What are the 10 most common types of eyewear hinges?

1. Standard Hinges

Design Features

Standard hinges are the most common type of eyewear hinge. They are typically made of metal barrels connected by a small screw that links the temple arms to the frame. These hinges are straightforward and practical, and they work for most everyday glasses.

Advantages

• Durability: Standard hinges are known for their robustness. They are typically very strong and can last for years, making them an excellent choice for customers who are rough on their glasses.
• Easy to Maintain: Since these hinges use screws, they are easy to repair if they come loose. For wholesale customers looking for low-maintenance, entry-level eyewear, standard hinges are an ideal choice.
• Cost-Effective: Standard hinges are budget-friendly, which makes them ideal for both custom and mass-market eyewear options.

Disadvantages

• Lack of Flexibility: The rigid design limits flexibility, which can make these glasses uncomfortable for individuals who frequently bend their temple arms or engage in high-intensity activities.
• Not Great for High-Impact Use: If glasses are often used in demanding environments or for sports, standard hinges may not offer the resilience needed to withstand these conditions.

Subtypes

• Three-Barrel Hinge: A simple design with three interlocking metal barrels. This is most commonly seen in everyday or budget eyewear.

• Five-Barrel Hinge: Offers more stability, making it popular in higher-end eyewear.

• Seven-Barrel Hinge: The most durable subtype, seven-barrel hinges are often used in heavy-duty eyewear for those needing extra strength.
