Eyeglass Frame Material Types: TR90 vs. Polycarbonate Frames

Sunglasses can be made from many different types of material. At Wooly, we provide both polycarbonate (PC) and TR90 frame materials for sport sunglasses, which are the most common and popular raw materials in the market. When comparing these two materials for sport sunglasses, the specific requirements and conditions associated with sports eyewear become particularly important. As a professional sport sunglasses manufacturer, Wooly will share this information in this article.

Polycarbonate (PC) Frames:

Advantages of Polycarbonate for Sport Sunglasses:

1. High Impact Resistance: Polycarbonate is known for its exceptional impact resistance. It’s a suitable choice for sports with a higher risk of impact, such as cycling, skiing, or racquet sports.
2. UV Protection: Polycarbonate naturally protects against harmful UV rays, an essential feature for outdoor sports.
3. Lightweight: Polycarbonate's lightweight nature ensures that the sunglasses won't contribute any unnecessary weight or discomfort during physical activities.

Disadvantages of Polycarbonate for Sport Sunglasses:

1. Potential for Brittleness: While polycarbonate is impact-resistant, it may become brittle over time, especially with prolonged exposure to harsh conditions, which could affect long-term durability.

TR90 Frames:

Advantages of TR90 for Sport Sunglasses:

• Flexibility and Durability: TR90 is a thermoplastic material that is highly flexible and durable, which can be beneficial in sports where the sunglasses may be subject to bending or twisting.
• Comfort: TR90's flexibility allows for a comfortable fit, and the material is less likely to cause discomfort during extended wear.
• Lightweight: Similar to polycarbonate, TR90 is lightweight, contributing to the overall comfort of the sunglasses.

Disadvantages of TR90 for Sport Sunglasses:

1. Less Impact Resistance: TR90 may not provide the same level of impact resistance as polycarbonate. This could be a drawback in high-impact sports.
2. Thicker Profiles: TR90 frames may appear thicker than polycarbonate frames, which could impact the aesthetics, though this is a subjective consideration.

Considerations for Polycarbonate and TR90 Materials:

1. Lens Quality: In addition to frame material, the quality of the lenses is crucial. High-quality lenses with proper coatings for anti-glare, anti-scratch, and polarization can enhance the performance of sport sunglasses.
2. Fit and Coverage: Regardless of the frame material, a secure and comfortable fit is essential for sports sunglasses. Additionally, a design that provides sufficient coverage to protect the eyes from wind, dust, and debris is important.
3. Ventilation: Adequate ventilation is crucial, especially in sports that induce sweating. Proper ventilation helps prevent fogging, ensuring clear vision during activities.

The best choice between polycarbonate and TR90 for sports sunglasses depends on the specific requirements of the sport, the wearer's preferences, and the environmental conditions in which the sunglasses will be used. Some sports may benefit more from the impact resistance of polycarbonate, while others may favor the flexibility and comfort of TR90.
