TR90 Optical Glasses Manufacturer

1. Are TR90 optical glasses more flexible than cellulose acetate or metal frames?

This is one of the core advantages of TR90 material. Compared to cellulose acetate and metal, TR90 optical glasses excel in flexibility and elasticity.

• Compared to cellulose acetate: Cellulose acetate is a rigid plastic. While it's easy to carve into rich colors and textures, resulting in outstanding texture, its inherent rigidity makes it prone to breakage under external force and unable to bend back to its original shape. TR90 optical glasses frames, on the other hand, can be bent significantly. For example, the temples can be opened far beyond their normal angle, and they will quickly return to their original shape after being released, without leaving permanent deformation. This memory property is something cellulose acetate lacks.
• Compared to metal: Metal frames, especially ordinary alloys, while possessing a certain degree of toughness, have a lower bending limit. Repeated adjustments can easily cause metal fatigue and breakage. Stainless steel and titanium frames offer better flexibility, but are generally more expensive. TR90 inherently possesses outstanding elasticity and impact resistance, capable of withstanding numerous accidental impacts and pressures, making it particularly suitable for manufacturing sporty optical glasses frames, providing wearers with added peace of mind.

2. Can TR90 blue light blocking glasses offer better comfort for prolonged screen time?

Absolutely. In fact, combining the material advantages of TR90 with blue light blocking functionality is an ideal solution tailored for users who spend long hours on digital devices.

• Lightweight and Pressure-Free: The low density of TR90 material makes TR90 blue light glasses extremely lightweight. There is virtually no pressure felt during extended wear; the force exerted on the bridge of the nose or the sides of the temples is negligible. This is the primary foundation of comfort, significantly reducing fatigue caused by excessive frame weight.
• Fit and Stable Fit: Due to its flexibility, the temples and nose pads of TR90 blue light glasses better adapt to different head shapes and nose bridge curves, providing a more snug and stable wearing experience. Even when looking down or moving around, they won't easily slip off, avoiding the hassle of frequently adjusting your glasses and allowing you to fully focus on the screen.
• Comprehensive Protection: Comfort comes not only from physical wear but also from visual experience. The lenses we've equipped in our TR90 blue light glasses effectively filter harmful blue light emitted from the screen, alleviating glare-induced dryness, eye strain, and visual fatigue. The combination of a lightweight frame and eye-protection features creates a comfortable screen-use experience all day long.

3. Is TR90 material suitable for making prescription lenses with higher diopters?

TR90 is an optical glasses frame material that is very suitable for making medium to high diopters prescription lenses, but there are some key manufacturing process requirements.

• Strength and Safety: For higher diopters, especially farsighted lenses, which are thicker in the center and thinner at the edges, there will be some tension on the frame. The tensile strength and toughness of TR90 material are sufficient to firmly hold the lens in place, reducing the risk of the lens falling out or breaking due to frame deformation, providing additional safety.
• Lightweight Advantages: High-prescription lenses (especially resin lenses) inherently carry weight. Using TR90, a lightweight material, to create the frames minimizes the weight of the lenses, maintaining the overall lightness of TR90 Optical Glasses and avoiding excessive strain on the nose and ears. This is crucial for improved wearing comfort.

To ensure that TR90 frames can goodly support high-prescription lenses, higher requirements are placed on the precision of the frame groove cutting, the uniformity of the lens rim, and the reinforcement design of the lens head. Our factory employs a reinforced core design and more precise grooving process when producing these optical glasses frames, ensuring that the frame does not deform under long-term use, providing a stable and reliable home for high-precision lenses.

4. Is the flexibility of TR90 optical glasses sufficient to adapt to different face shapes?

The outstanding flexibility of TR90 material gives it exceptional adaptability, better serving a variety of face shapes, which is one of the main reasons for its popularity.

• Adaptable Temple Adjustment: The temples of TR90 Optical Glasses can be adjusted to widen or narrow to match the head width of different customers. Whether the user has a wide or narrow head circumference, fine-tuning can be done under the guidance of a professional to achieve good clamping force, avoiding excessive tightness or slippage.
• Frame Inclusivity: Although the overall shape of the frame is fixed, its inherent flexibility allows it to adapt to slight changes in facial curvature to a certain extent. This ability to deform slightly allows it to fit more naturally to the face.
• Advantages of Personalized Customization: From a manufacturing perspective, TR90 material is easily manufactured into various ergonomic curved designs through injection molding. This means that we can create TR90 blue light glasses and optical frames with curvatures that better fit major face shapes during the design phase. Its softness over rigidity characteristic makes it less picky about face shape than rigid materials, thus providing a comfortable and fitting wearing experience for a wider range of consumers.
