“Fishing sunglasses are a performance product first. The buyers who succeed don’t start with frame style—they start with lens specs and fit: polarization quality, coating durability, salt/sweat resistance, and wrap geometry that blocks side glare without pinching. If your factory can’t validate those with repeatable testing and assembly control, returns will eat the margin.”

Whether you’re sourcing sunglasses for a fishing brand or building your own line from scratch, one thing’s for sure — not all fishing sunglasses are created equal.

Sure, they all look cool on the surface. But what separates a cheap pair from one that serious anglers swear by? It’s not just about throwing on a polarized lens and calling it a day. It’s about smart design, functional materials, performance coatings, and a manufacturer who knows what the fishing crowd really needs.

At EyewearBeyond, we’ve worked with outdoor brands from all over the world — many of them stepping into fishing eyewear for the first time. The biggest mistake we see? Underestimating the manufacturing details that make or break a product.

So, in this guide, we’re pulling back the curtain.

From lens tech and mold development to frame design, packaging, and QC — we’ll walk you through exactly how fishing sunglasses are made, and how you, as a brand or distributor, can make smarter decisions when sourcing.

Let’s dive in.

2. How to Design Fishing Sunglasses? The Procedures and Components

Designing fishing sunglasses isn’t just about picking a frame and slapping on a polarized lens. For brands that want to stand out — whether you’re targeting pro anglers, casual weekend fishers, or even coastal lifestyle markets — you need a design that’s both functional and marketable.

So where do you start?

2.1 The Key Steps in Designing Fishing Sunglasses

1. Define your target market and product positioning
Are you building for offshore saltwater fishing? Fly fishing in rivers? Youth or women-specific designs? Maybe your customer base needs RX insert compatibility, or just a stylish yet practical model for lifestyle wear.
Knowing your customer drives every design decision — from shape and fit to material and price point.

2. Let creativity meet brand identity
This is where your ideas and your brand story come together.

• What colorways represent your style?
• Do you want sporty lines, or something sleeker?
• Will your lenses be mirrored, photochromic, or classic amber?
  Build a look that aligns with your brand DNA — and offers something different from what’s already flooding the market.

3. Turn sketches into reality
Even a rough drawing helps. Many brands start with hand sketches, then move to 3D modeling (CAD) to preview the shape, lens curvature, and frame angles. These files are later used for mold creation and production sampling.

4. Choose the right lens materials and coatings
Lenses aren’t just about vision — they’re about protection and performance.
You’ll need to decide on:

• Polarized TAC or polycarbonate?
• UV400 coatings?
• Mirror, hydrophobic, or anti-fog layers?
  The fishing environment is harsh — lenses must perform in bright sun, salt spray, and wet conditions.

5. Find a reliable designer or manufacturer
If you’re not handling the CAD work in-house, work with a design partner or factory that understands sports eyewear structure.
Where to find them?

• Alibaba – for manufacturers with mold capabilities
• Fiverr/Upwork – for freelance eyewear designers
• LinkedIn – to find B2B-experienced product developers

Working with experienced suppliers like EyewearBeyond, who’ve done this before, also saves a ton of back-and-forth.

2.2 Design Tips & Functional Considerations

To build a high-performing fishing sunglass model, here are a few design elements you’ll want to get right:

• Frame structure:
  Choose wraparound designs for maximum glare protection and side coverage. OTG (over-the-glasses) designs work great for prescription wearers. Magnet-based lens swapping is a growing trend in performance fishing eyewear.
• Lens system:
  Use dual-layer or interchangeable lenses for flexibility. Pro users appreciate the ability to switch lenses based on light conditions (e.g. sunny vs cloudy vs low light).
• Ventilation design:
  Include top/side vents to reduce fogging in humid or early morning conditions. Poor ventilation is one of the biggest reasons users abandon even well-made frames.
• Surface finish:
  Matte rubberized textures offer better grip when wet. You can also explore gloss, water-transfer prints (camo is popular), or custom electroplated accents.
• Logo placement:
  Think beyond just one spot. Brands often place logos via:
  • Laser etching on the lens
  • Silk printing on the temple
  • Woven patch or rubber badge on the head strap (for floating styles)

Don’t forget — good design also makes assembly, packaging, and customization easier later on

3. 7 Types of Fishing Sunglasses

Not all fishing is created equal — and neither are fishing sunglasses.

From deep-sea trolling to fly fishing in shaded rivers, different environments call for different eyewear features. If you’re building a product line or deciding what to stock, it’s crucial to know what kinds of sunglasses real anglers are actually looking for.

Here are seven tried-and-true types of fishing sunglasses — each with a purpose, and a target market.

3.1 Wrap-Around Fishing Sunglasses

The classic go-to for hardcore anglers. These glasses hug the face closely, providing maximum side protection from glare, wind, and water spray. The wrap design also helps keep them secure during fast movement or rough boat rides.

Ideal for:

• Deep-sea and offshore fishing
• High-glare environments
• Full-day wear under the sun

Most pro-level fishing sunglasses fall into this category — and for good reason.

3.2 Interchangeable Lens Models

Light conditions on the water can shift fast — cloudy mornings, blazing afternoons, golden-hour casts. That’s where interchangeable lens systems shine.

Popular features include:

• Magnetic or click-in lens swaps
• Lens kits with multiple tints (gray, yellow, copper)
• Storage case for extra lenses

A favorite for serious fishers who want more than one lens in a single frame.

3.3 Polarized Fishing Sunglasses

This one’s non-negotiable. Polarized lenses cut glare off the water’s surface, making it easier to spot fish, protect the eyes, and reduce fatigue. Most fishing customers expect this by default — even at entry-level price points.

Popular lens tints:

• Amber: Great for contrast and cloudy days
• Gray: True color and bright sun
• Copper: Excellent for freshwater fishing

Polarized styles can be paired with any of the other frame types listed here.

3.4 Photochromic (Light-Adaptive) Sunglasses

Photochromic lenses adjust to changing light automatically — they darken in strong sun and lighten in shade. This is a solid option for fishers moving between sun and shadow, or for those who want “one pair that does it all.”

Pros:

• No need to swap lenses
• Often combined with polarization
• Comfortable for long-term wear

Great for river and lake fishing where shade lines change often.

3.5 Urban/Coastal Lifestyle Sunglasses

These are for the casual angler who might cast a few lines at sunset, then hit the beach bar after. Still polarized, still functional — but with a more lifestyle-driven design.

Features:

• Fashionable shapes (aviator, square, low-profile wraps)
• Lightweight builds for all-day comfort
• Often preferred by younger or female anglers

If your brand targets a broader outdoor audience, these are a smart addition.

3.6 RX Insert Fishing Sunglasses (Prescription-Ready)

Many anglers need prescription lenses — but full RX fishing sunglasses are pricey and limited in style. That’s where RX inserts come in.

Structure:

• Regular fishing sunglasses with an internal clip-in insert
• Insert holds prescription lenses
• Easy to replace as prescriptions change

This is a cost-effective, versatile solution for prescription wearers — and growing fast in demand.

3.7 Youth & Small-Fit Fishing Sunglasses

Don’t overlook the next generation. More and more parents are bringing kids into the sport, and they need gear that fits properly.

Youth versions often include:

• Smaller wraparound frames
• Lightweight materials
• Bright colors or fun patterns
• Same UV400 + polarized protection as adult models

If you’re building a family-friendly or beginner-friendly fishing eyewear range, this category adds real value.

4. Lens Technologies for Fishing Sunglasses

If there’s one thing that truly defines a fishing sunglass — it’s the lens.

Out on the water, your customer isn’t just looking for style. They’re depending on their lenses to cut glare, reveal fish beneath the surface, and protect their eyes all day long. So if you’re developing your own fishing eyewear line, understanding lens technologies isn’t optional — it’s mission critical.

Let’s break down the essentials.

4.1 UV Protection

At bare minimum, every pair of fishing sunglasses should offer UV400 protection — blocking 100% of UVA and UVB rays. This isn’t just about eye health. Extended exposure to UV can cause headaches, fatigue, and long-term vision issues — especially on reflective water.

Good UV protection is:

• Built into the lens material (like PC or TAC), not just coated
• Long-lasting, and doesn’t wear off over time
• A key spec for CE/FDA certification

Pro tip: If you’re sourcing or producing for the US/EU market, UV protection is non-negotiable.

4.2 Anti-Fog Coating

Fogged-up lenses in the middle of a cast? Instant frustration.

Especially in humid coastal climates or early mornings, anti-fog coatings are a premium value-add. Some factories apply anti-fog directly to the lens interior; others offer aftermarket wipes or sprays as part of your packaging set.

Look for:

• Hydrophilic coatings that absorb moisture and resist condensation
• Fog-resistant venting systems (combined with smart frame design)
• Optional lens inserts for double-layer protection

Offering anti-fog features — even as an upgrade — gives your line an edge.

4.3 Anti-Scratch Coating

Fishing sunglasses go through a lot: tossed in tackle boxes, dropped on rocks, smudged by sunscreened fingers. That’s why a solid anti-scratch layer makes all the difference.

Most factories apply a hard coating (HC) to the front and back of the lens — especially if you’re using TAC (Tri-Acetate Cellulose), which is softer than PC or nylon.

Ask your supplier:

• Is the anti-scratch coating applied on both sides?
• Can it withstand saltwater conditions?
• What’s the average abrasion test result (e.g., Bayer test rating)?

Good scratch resistance extends product life and protects your brand reputation.

4.4 Lens Ventilation Systems

This is less about coatings and more about smart design — but it directly affects lens clarity.

Ventilation in fishing sunglasses helps:

• Prevent fogging (especially when air is still)
• Regulate temperature between face and lens
• Increase comfort during long wear

Common styles include:

• Top vents above the lens
• Side cutouts
• Integrated lens+frame airflow channels

Some high-end models also feature dual-layer lenses with internal air gaps — like snow goggles — for extreme environments.

5. Frame Design and Fit Features

Lenses may handle the optics, but the frame is what keeps the entire product wearable. Out on the water, that means grip, stability, and all-day comfort — whether you’re battling fish or just waiting under the sun.

Here are some critical frame design features you should think through when developing your own fishing eyewear.

5.1 Adjustable Nose Pads

Not all noses are shaped the same — and that matters more than you’d think.

High-quality fishing sunglasses often feature adjustable nose pads made from soft, flexible rubber (like TPE or silicone). This helps:

• Improve comfort over long hours
• Keep glasses from sliding when the face gets sweaty or wet
• Accommodate different nose shapes across regions (a must for global brands)

Some brands also opt for metal-core nose pads that can be manually bent for a custom fit.

Bonus tip: If you’re targeting both Western and Asian markets, adjustable nose pads can help solve regional fit differences without needing separate SKUs.

5.2 Temple Grip & Arm Length

Let’s face it: sunglasses that keep sliding down or squeezing your head are an instant no-buy. That’s why temple design is just as important as lens clarity.

Here’s what to consider:

• TPE or rubber temple tips for a non-slip hold
• S-bend or wraparound temples to hug the head
• Spring hinges or flexible arms to accommodate different head sizes
• Ideal arm length: 120–140mm (depending on your target customer segment)

Whether you’re designing for deep-sea pros or weekend shore fishers, a secure temple fit prevents constant adjustment — and that’s a big deal when hands are tied up with rods, bait, or steering the boat.

5.3 Helmet & Cap Compatibility

Unlike cycling or motorsports, fishing isn’t always helmet-heavy. But many anglers wear baseball caps, bucket hats, or buffs — and that affects frame fit.

A few helpful design considerations:

• Low-profile top frames that slide under hat brims
• Thin temples that don’t dig into the side of the head under caps
• Flat or slightly curved temple tips for comfort under wide-brim hats

If you’re planning a multi-sport or crossover model (e.g. for hiking or boating too), you may want to test helmet compatibility during sample development.

6. Pattern Making and Mold Development

Once your fishing sunglasses design is finalized — with lens shape, frame style, fit details, and functional features — the next big step is turning it into a physical mold. This is the foundation of manufacturing consistency.

If you’re going the OEM or private label route, understanding how molds are made helps you:

• Avoid costly mistakes
• Communicate clearly with your supplier
• Plan for product development timelines

Let’s break it down.

6.1 What Is Pattern Making in Eyewear?

Pattern making in eyewear is the creation of technical drawings and physical mockups that define every angle, curve, and dimension of the sunglasses.

This typically includes:

• 2D technical sketches (with exact dimensions)
• 3D CAD models showing depth and curvature
• Lens radius and base curve calculations
• Hinge and screw positioning
• Surface texture references (e.g. matte, gloss, rubber finish)

These files are used to create prototypes and eventually — the injection mold.

6.2 Mold Development for Fishing Sunglasses

Here’s where things get technical (but don’t worry — your manufacturer handles most of it). Still, as a buyer or brand, it’s helpful to know what happens behind the scenes.

There are usually two molds made:

• Frame mold: For the front frame and temples, usually via injection molding
• Lens mold: For curved lenses, especially if using polycarbonate or nylon materials

Key decisions at this stage:

• Do you need interchangeable lens support?
• Will the frame be one-piece or multi-part assembly?
• Are you adding features like rubber nose pads or metal logo inlays?

Each of these decisions can affect mold complexity and cost.

6.3 Cost and Timeline of Mold Creation

• Mold cost (for sunglasses): Typically ranges from $1,500 to $5,000+ USD, depending on complexity
• Time to build: Usually 25–40 days
• Modifications: Once a mold is made, changes are limited and expensive — so triple-check your design and samples before final approval

Many manufacturers, like EyewearBeyond, offer digital mockups and 3D-printed samples before committing to full metal mold tooling. Take advantage of that — it’s cheaper and faster to tweak digital files than a steel mold.

6.4 Customization vs. Using Existing Molds

If you’re not ready to invest in custom tooling, you can:

• Choose from existing frame molds
• Customize surface finish, color, lens tint, and logo

This is a common route for first-time brands or limited-budget projects, and with the right design tweaks, you can still create a unique product.

7. Materials Used in Fishing Sunglasses

Fishing sunglasses need to survive a brutal combo: saltwater, UV rays, sweat, heat, and impact. That’s why smart material selection isn’t just about price — it’s about performance, durability, and long-term customer satisfaction.

Here’s what the best manufacturers (and smart buyers) look for.

7.1 TR90 Frame Material

This is the gold standard for most performance sports frames — and for good reason.

TR90 is a type of thermoplastic that’s:

• Ultra lightweight
• Highly flexible (can bend without breaking)
• Resistant to heat and UV damage
• Won’t lose shape even under stress

For fishing sunglasses, TR90 is ideal because it’s comfortable for all-day wear and tough enough to handle rough use — whether it’s dropped on a dock or exposed to hot car dashboards.

Some brands use Grilamid TR90, a Swiss-made version known for superior consistency.

7.2 Polycarbonate Lenses

Ask any seasoned eyewear manufacturer: polycarbonate (PC) is the top lens choice for outdoor sports eyewear.

Why?

• Impact-resistant — won’t shatter like glass
• Lightweight — important for large or wraparound lenses
• Built-in UV protection
• Can easily be polarized or mirror-coated

Another plus? PC lenses are thinner than TAC lenses at the same strength, making them great for sleek designs.

Note: If you’re targeting the premium market, nylon lenses are another option — slightly clearer optically and even more durable, but more expensive.

7.3 TAC Lenses (Tri-Acetate Cellulose)

TAC lenses are widely used in mid-range fishing sunglasses. They’re:

• Naturally polarized
• Lightweight
• Cost-effective
• Smooth to the touch

But — they’re also less impact-resistant than PC, and scratch more easily. That’s why TAC lenses almost always come with a hard coating to improve durability.

TAC is ideal for brands looking to hit competitive price points without sacrificing optical clarity.

7.4 TPE or Silicone Grips

No one wants sunglasses sliding down their nose mid-cast.

That’s where TPE (Thermoplastic Elastomer) or silicone inserts come in. These are used in:

• Nose pads
• Temple tips
• Inner bridge pads

They help sunglasses stay put — even when wet or sweaty — and improve comfort over long hours.

7.5 Metal Hinges and Logos

Small details, big impact.

• Stainless steel hinges add strength and premium feel
• Spring-loaded hinges improve fit for wider face sizes
• Metal logo inlays create a high-end finish and brand identity

These are commonly found in mid-to-high-end fishing eyewear.

7. What Materials Are Commonly Used in Fishing Sunglasses?

When it comes to manufacturing fishing sunglasses that truly perform, the materials matter just as much as the design. These aren’t casual fashion sunglasses — they’re built to handle intense sunlight, reflected glare, saltwater corrosion, and high-impact use. Choosing the right materials is what separates premium, pro-level gear from throwaway products.

Let’s break down the core materials used in fishing sunglass production — and why they matter.

7.1 Lens Materials

Polycarbonate (PC)

• Impact-resistant, lightweight, and naturally blocks UV.
• Perfect for wrap-around lenses and full-coverage styles.
• Can be combined with polarization, mirrored coatings, and anti-fog layers.

Polycarbonate is the go-to for high-performance fishing eyewear. It handles rough use and offers excellent optical clarity on the water.

TAC (Tri-Acetate Cellulose)

• Often used for polarized lenses at mid-range price points.
• Lightweight and flexible but more scratch-prone than PC.
• Requires hard coating to improve durability.

TAC lenses are ideal for budget or entry-level models that still require quality polarized performance.

Nylon

• Premium lens material, with superior clarity and flexibility.
• More resistant to warping under heat.
• Great for high-end, lightweight fishing sunglasses.

7.2 Frame Materials

TR90 (Grilamid)

• Flexible, durable, and extremely lightweight.
• Resists heat, UV, and chemical exposure (ideal for saltwater environments).
• Comfortable for long wear — doesn’t dig into ears or nose bridge.

TR90 is by far the most common choice for fishing sunglass frames, and trusted by top brands worldwide.

TPR / TPE Rubber

• Used for nose pads, temple tips, and anti-slip grips.
• Soft, comfortable, and increases stability even when wet.
• Can be over-molded onto TR90 frames.

7.3 Logo and Detail Materials

• Silicone or PVC: Often used for 3D logos or strap branding.
• Stainless Steel or Aluminum: Used for inlaid logos, hinge components, and spring arms.
• Silk screen ink or laser etching: Used for permanent logo applications on lens or frame surfaces.

Pro Tip: If you’re targeting a premium segment, a combination of nylon lenses + TR90 frame + over-molded rubber grips offers a perfect balance of durability, comfort, and optical performance.

8. Cutting, Assembling, and Finishing

Once the materials are ready — from lenses to frames — the actual build process begins. This stage involves precise lens cutting, careful frame assembly, and the all-important finishing touches that elevate your fishing sunglasses from “factory output” to “retail-ready product.”

Let’s walk through how high-quality fishing sunglasses are put together, piece by piece.

8.1 Lens Cutting Methods

The first step is shaping the raw lens material into the perfect form. Since many fishing sunglasses use wraparound or curved lenses, accuracy is everything.

Two main methods are used:

• CNC Cutting (Computer Numerical Control):
  Lenses are cut with incredible precision using a rotating blade system guided by CAD files. This allows for consistent cuts even with complex lens shapes and base curves.
• Laser Cutting:
  Ideal for thinner lenses or when ultra-clean edges are required. Laser-cutting is contactless and reduces the risk of cracking or scratching during the process.

Before cutting, the factory aligns the polarization film (for polarized lenses) to ensure it sits at the correct optical angle — usually around 37–45 degrees for fishing-specific use.

8.2 Frame Assembly Process

Next comes the frame. Depending on the design, assembly can be straightforward or require more advanced integration.

Here are a few common frame styles:

• Snap-In Lens System (most common):
  Lenses are pressed into the frame’s inner groove, held securely by pressure and fit.
• Lock-In / Clip Mechanism:
  Used for interchangeable lens models, where users can swap lenses themselves. Often includes small release tabs.
• Magnetic Interchangeable Systems:
  A premium option found in higher-end fishing sunglasses. Magnets allow for fast, tool-free lens swaps while keeping the lens stable during use.

Throughout the process, the assembly team ensures the lens curvature matches the frame design (typically Base 6 to Base 8 curves in fishing eyewear) to prevent gaps, warping, or stress on the lens.

8.3 Key Assembly Considerations

• Polarization Alignment:
  Getting this wrong can result in glare instead of protection. Good factories test the polarization direction during assembly with a light test.
• Frame Fit and Flex Check:
  After lenses are installed, temples are opened/closed repeatedly to check for tension, symmetry, and proper hinge action.
• Lens Seating Pressure:
  If pressure points are uneven, it can cause lens warping or stress fractures. Proper tool usage is key — especially with PC or TAC lenses.

8.4 Final Polishing and Cleaning

The last step is all about refinement.

• Frame and lens edges are gently polished to remove any sharp mold lines or burrs.
• Lens surfaces are cleaned with microfiber cloths and compressed air — no smudges, no particles.
• If your product includes mirror coating, this step is done extra carefully to avoid scratches or peel-offs.

Some factories also do a final anti-fog spray or UV test before packaging.

9. Seams, Assembly Points, and Fastening Details

When it comes to outdoor eyewear — especially fishing sunglasses — how parts come together matters just as much as the materials themselves.

Why? Because these are the micro-details that impact durability, flexibility, ease of repair, and waterproof performance. And if you’re targeting the high-performance market (like saltwater anglers), these fine points can make or break your product’s long-term value.

Let’s break down the key assembly details to keep an eye on.

9.1 Hinge Systems: Screws vs. Screwless

One of the most important joints in any pair of sunglasses is where the temple (arm) meets the frame.

• Traditional Metal Screws
  • Most common in fishing sunglasses, especially for TR90 frames.
  • Easy to tighten or repair.
  • Use stainless steel to prevent rust from saltwater exposure.
  • Requires torque calibration during assembly to avoid cracking frame plastic.
• Screwless / Snap-Fit Hinges
  • Popular for minimalist or sport-style frames.
  • Reduce weight and eliminate corrosion risk.
  • Typically use built-in flex or pressure-fit mechanisms.
  • Not repairable — the whole arm may need replacement.

For ocean or boat use, many brands opt for rust-proof spring hinges for added flexibility and better long-term performance.

9.2 Lens Replacement Systems

Some fishing sunglasses — especially higher-end or all-weather models — come with interchangeable lenses.

The two most popular mechanisms:

• Magnetic Lens Swap System
  • Quick-change, premium feel.
  • Requires strong rare-earth magnets built into the frame.
  • Needs precise mold alignment to avoid misfits or light leakage.
• Quick-Release / Clip Systems
  • Small tabs or slots lock the lens in place.
  • Affordable and durable, but slightly more time-consuming to change.
  • Ideal for frames where users carry multiple lenses (e.g., mirror + clear + low light).

For fixed-lens designs, these features are skipped entirely — but precision fitting is still critical to prevent edge chipping or internal stress cracks.

9.3 Nose Pad Attachment Styles

The nose bridge is another area where construction choices affect comfort and longevity.

• Replaceable Nose Pads
  • Often mounted on metal stems with adjustable angles.
  • Easy to swap out — good for hygiene and long-term use.
  • Best option for multi-regional fit (Asian vs. Western nose profiles).
• One-Piece Molded Nose Pads
  • Part of the TR90 or rubber-injected frame.
  • Sleek, seamless, and durable — but non-adjustable.
  • Common in wrap-around sports models.

Higher-end fishing sunglasses sometimes combine both: a molded rubber pad on an adjustable core, offering both comfort and custom fit.

9.4 Waterproof & Seal Design (for Saltwater Use)

For ocean fishing, exposure to salt, humidity, and spray is inevitable. That’s why water resistance isn’t just for electronics.

Smart sunglass brands address this with:

• Internal rubber gaskets between lens and frame to prevent seepage
• Sealed screw inserts to block saltwater corrosion
• Water-repellent coatings on lenses and frames
• Drainage grooves near the nose bridge or bottom edge (to avoid water pooling)

These are especially important for saltwater-specific or boat-use models in your product line.

When you’re designing for real-world use — not just for show — these connection points tell the story of your product’s durability. Customers don’t see them immediately, but they’ll remember if something breaks or rusts after two trips.

10. What Are the Measurement Points for Fishing Sunglasses?

Every good frame starts with great measurements. While most end-consumers may not notice them at first glance, these technical specs determine everything from wearability to lens visibility range, helmet compatibility, and retail fit rating.

If you’re working on your own private label or OEM fishing sunglass line, here are the key measurement points your manufacturer (or spec sheet) should cover:

10.1 Lens Width

• The horizontal width of a single lens at its widest point.
• Usually ranges between 58mm to 72mm depending on whether the frame is wrap-around or rectangular.
• Wider lenses = more coverage, better side protection from reflected glare on water.

10.2 Lens Height

• The vertical dimension of each lens from top to bottom.
• Important for determining field of vision and cheek contact.
• In fishing sunglasses, taller lenses are common, especially for full-shield styles.

10.3 Bridge Width (Nose Gap)

• Distance between the two lenses, measured at the bridge.
• Determines nose fit and whether the sunglasses will sit properly or slide.
• For global fit (including wider Asian nose profiles), bridge width should be designed between 14mm to 20mm or paired with adjustable nose pads.

10.4 Frame Width

• Total width from one outer temple to the other.
• Critical for choosing the correct fit range (S / M / L face sizes).
• Standard unisex fishing frames usually measure 135mm to 150mm in full width.

10.5 Temple Length

• The length of the sunglass arms from the hinge to the tip behind the ear.
• Common ranges: 120mm – 140mm.
• Needs to be long enough for grip, but short enough for helmet compatibility or cap wearers.

10.6 Wrap-Around Angle / Frame Curve

• This refers to how curved the frame is around the face (often called base curve).
• Most fishing sunglasses fall into Base 6 to Base 8 range — higher curve means better peripheral coverage and wind protection.
• Needs to be aligned with lens curvature during assembly to avoid stress points.

10.7 Face Fit Curve

• This is more of a 3D metric — the combination of curve, nose pad spacing, and temple tension.
• Factories use dummy heads or digital headform models (Asian, European, US) to test this.
• A snug fit without pressure points = less slippage and more comfort on long days near the water.

11. Printing and Branding Techniques for Fishing Sunglasses

When someone picks up your fishing sunglasses, what makes them remember your brand? It’s not just performance — it’s the visual identity. The logo on the lens. The clean silk print on the arm. The woven label on the strap. And yes, even the way the box opens.

Here’s how experienced manufacturers bring branding to life in fishing sunglasses:

11.1 Laser-Etched Logos on Lenses

• Subtle, sleek, and long-lasting, laser engraving is the go-to option for logos on polycarbonate or nylon lenses.
• Applied during or after the lens coating process.
• Doesn’t peel, fade, or interfere with vision.
• Common placement: bottom right or left corner of the lens.

Pro tip: Laser-etched logos give a premium feel — and work especially well on mirrored or polarized lenses.

11.2 Silk Screen Printing on Frame Surface

• A versatile and cost-effective branding method, perfect for temple arms, bridge areas, or even inner frame markings.
• Can be done in multi-color, metallic, or matte ink.
• Requires UV-resistant ink for outdoor performance — especially in saltwater conditions.

11.3 3D Rubber or Silicone Badges

• Often used on straps or soft cases, but can also be added to temples.
• Adds tactile branding that stands out in hand and in photos.
• Works great for sportier, rugged product lines.

11.4 Woven Labels and Printed Straps

• For sunglasses with adjustable straps (common in wrap-around or floating designs), branding can be woven into the elastic or printed via heat transfer.
• Durable even with sweat, water, and sun exposure.
• Ideal for models targeting kayak fishing, deep-sea anglers, or boat crew use.

11.5 Custom Packaging Options

• Branded boxes, microfiber pouches, and cleaning cloths round out the brand story.
• Print your care instructions, lens type, and UV rating right into the package — it’s functional and educational.
• Add QR codes for authenticity or product registration, especially for mid-to-high-end offerings.

For brands in the fishing eyewear space, your logo doesn’t just sit on the product — it speaks for your reliability. The key is choosing branding methods that hold up to water, heat, and repeated use.

12. Packaging and Branding Essentials

You’ve got a great product — polarized lenses, anti-scratch coatings, water-repellent frames. But how do you make sure your customer remembers your brand the moment they unbox it?

That’s where thoughtful packaging comes in.

Whether you’re targeting the premium sport market or launching a more budget-friendly SKU, your packaging is part of your identity — and it needs to reflect durability, functionality, and professionalism.

12.1 Packaging Options

Here are the most commonly used packaging formats in fishing sunglasses manufacturing:

• EVA Hard Cases
  • Durable, impact-resistant, and perfect for premium models.
  • Often include internal mesh pouches for spare lenses or accessories.
  • Logo can be printed or embossed directly on the surface.
• Nylon Soft Pouches
  • Lightweight, protective enough for everyday use.
  • Doubles as a cleaning cloth.
  • Easy to brand with heat transfer prints or woven labels.
• Color-Printed Paper Boxes
  • Essential for retail presentation.
  • Can be fully customized with UV spot gloss, matte lamination, embossing, or eco-friendly kraft finishes.
  • Inserts can be molded to hold the sunglasses snugly during transport.

12.2 What Goes Inside the Box?

A smart packaging setup doesn’t stop at the case or pouch. Consider including:

• Microfiber Cleaning Cloth — Branded, if possible.
• Extra Lenses — If you’re offering interchangeable lens models.
• Instruction Manual — Include care tips, anti-fog directions, or warranty info.
• Thank You Cards / QR Codes — Direct customers to your website, product registration, or social media.

These small additions go a long way in helping your fishing sunglass brand feel premium and professional.

12.3 Branding on Accessories

Your logo and design language shouldn’t stop at the frame. You can extend your identity across:

• Straps (if included): Printed, woven, or silicone-badged.
• Zippers (on EVA cases): Can be embossed or rubber-tipped with your logo.
• Hanging Tags: Attach with SKU, barcode, product story, and material specs.
• Inner Box Inserts: Great for storytelling or brand mission content.

Think of your packaging as a silent salesperson — it’s doing the talking when you’re not around. For B2B buyers, that extra polish helps with retail display, product differentiation, and ultimately… repeat orders.

13. Lens Care and Maintenance Tips

No matter how well a pair of fishing sunglasses is built, how your customer takes care of them will directly impact longevity. And as a brand or wholesaler, providing clear care guidance not only helps reduce complaints and returns — it adds credibility to your product.

Here are a few smart practices and care tips that are commonly included in instruction manuals, hang tags, or packaging inserts for fishing sunglasses.

13.1 How to Clean the Lenses Properly

• Always use the provided microfiber cloth.
• Avoid paper towels, tissues, or shirt corners — these can scratch the coating.
• For stubborn dirt (especially from saltwater), rinse gently with clean, lukewarm water first before wiping.
• Never use alcohol or window cleaner — they can strip mirror coatings or anti-fog layers.

Consider printing a small cleaning icon on the box or lens film as a reminder.

13.2 Proper Storage Guidelines

• Always store sunglasses in their designated case when not in use.
• Avoid placing them face-down on any surface.
• Never leave sunglasses inside a hot car dashboard or under direct sunlight for hours — extreme heat can warp frames or delaminate lenses.
• After saltwater use, rinse frames and lenses with fresh water to prevent corrosion or residue build-up.

13.3 Anti-Fog Tips for Fishing Use

• For glasses that come with anti-fog coatings, instruct users to avoid wiping the inside of the lens aggressively.
• If fogging occurs in humid or temperature-fluctuating environments, suggest using a non-abrasive anti-fog spray or wipe — many brands even include one in the box.
• Encourage users to clean regularly — oils and smudges can compromise anti-fog performance.

13.4 How to Turn This into Brand Value

Simple care tips not only protect the product — they also become brand-building touchpoints. You can:

• Include a branded lens care card in every box
• Print QR codes on packaging that link to care tutorials or FAQ pages
• Add lens care info to your online product pages for customer support

Ultimately, your customer’s experience doesn’t end when they put the glasses on — it continues with how they care for them. Giving guidance shows you care too.

14. Quality Control & Final Inspection

No matter how sleek your design is or how premium the materials are — if quality control isn’t in place, your sunglasses simply won’t stand up to real-world use.

Especially for fishing sunglasses, where exposure to sun, salt, sweat, and water is constant, factory-side inspection procedures must be thorough. As a brand or wholesaler, knowing what QC steps your manufacturer follows is essential to avoid surprises post-shipment.

Let’s break down what a solid QC process should include:

14.1 Lens Inspection

• Clarity Check: Ensuring lenses are free from bubbles, distortions, or scratches.
• Polarization Test: Verifying correct alignment of the polarizing film — especially critical in fishing eyewear.
• Coating Check: Making sure mirror, anti-fog, and UV coatings are even, not peeling or streaked.

Many factories use a polarization testing chart or rotating filter tool during inspection.

14.2 Frame & Fit Testing

• Symmetry Check: Both temples open/close evenly, no warping or tilt.
• Flex Test: Gentle pressure applied to arms and nose bridge to ensure elasticity without cracking.
• Hinge Test: If using screws or spring hinges, tightening and opening/closing cycles to test durability.

For TR90 or injected frames, cooling and shrinking deformation must also be checked post-molding.

14.3 Functionality Verification

• Lens Swap Mechanism Test (for interchangeable models): Ensuring magnets or clips align correctly.
• Grip & Fit Simulation: Try-ons on dummy headforms to ensure comfortable, stable fit across sizes.
• Anti-Slip Test: Especially on models with rubber temples or nose pads — sunglasses should stay in place during simulated movement.

14.4 Final Assembly & Packaging QC

• Logo Position Check: Ensuring printed or laser logos are clean and correctly placed.
• Accessory Count: Confirm that cleaning cloth, case, extra lenses, manuals, and packaging match the packing list.
• Barcoding / Labeling: Check hang tags, box stickers, and inner tags for SKU accuracy.

14.5 Optional: Third-Party Inspection

For brands ordering in bulk, especially for export, it’s common to bring in a third-party QC service (like SGS, TUV, or Intertek) to run final checks on-site before shipment.

They’ll typically perform:

• AQL Sampling (Acceptable Quality Limits)
• Drop Tests
• UV400 Testing
• Salt Spray Testing for hinges and screws (for marine models)

A product that looks great but fails in the field isn’t just a return — it’s a hit to your brand reputation. Smart QC ensures your sunglasses not only look premium but act like it too.

In Conclusion
