Custom Eyewear Mold Costs: When Is New Tooling Necessary?
A buyer sends a new eyewear design to several suppliers and receives three very different tooling quotations. One supplier charges only a small development fee.

Why Do Sunglass Lenses Pop Out? Manufacturing Causes and Fixes
A sunglass lens can look perfectly secure during sample approval and still pop out after shipping, heat exposure or repeated temple opening. When this happens, the first explanation is usually simple: the lens was cut too small. That is possible, but it is not the only cause. In some cases, the lens is actually too […]
3-Barrel vs 5-Barrel vs 7-Barrel Eyewear Hinges: An OEM Guide
Is a 7-barrel hinge really stronger than a 5-barrel hinge, or does it simply place more metal inside the temple? This question comes up frequently during custom eyewear development.

Sunglass Lens Coatings: AR, Hard Coating, Hydrophobic and Oleophobic Options
Choosing sunglass lens coatings sounds like a small technical detail. In real OEM production, it is not small. It affects how the sunglasses look after transport, how easily customers clean them, how premium the product feels in hand, and how many complaints a brand may receive after launch. Many buyers spend a lot of time […]
How to Choose a Titanium Eyewear Manufacturer: Technical Checks for Brands
Choosing a titanium eyewear manufacturer is not the same as sourcing a normal metal frame supplier. From a distance, many titanium frames look similar. They are lightweight, clean, slim, and easy to present as premium eyewear. But for brands, the real risk is not whether the sample looks beautiful on a table. The real risk […]
