Plastic Steel Optical Glasses

These glasses combine the ultra-light, flexible qualities of a TR90 (thermoplastic) frame with the sturdy, refined support of plastic-steel temples, topped with advanced blue-light-filtering lenses. Designed for both comfort and durability, they are ideal for prolonged screen use and everyday wear.

1. TR Frame
Lightweight & Comfortable: TR (e.g., TR90 or similar thermoplastic memory resin) is notably low in density and weight, offering minimal pressure on the nose and ears—making extended wear fatigue-free. 

Highly Durable & Flexible: Known for high flexibility and impact resistance, this material withstands bending and deformation and retains its shape—perfect for active use. 

Skin-Friendly & Hypoallergenic: Plastic frames—including TR90 types—are less likely to cause skin irritation, unlike many metals that contain nickel or other allergens. 

Stylish & Customizable: TR90 frames are easily dyed or patterned, offering endless options—from translucent, “jelly” tones to vivid opaque colors—for contemporary aesthetics. 

2. Plastic-Steel Temples
Premium Look & Stability: Plastic-steel (a hybrid of plastic and steel or a composite “plastic steel”) provides a luxurious aesthetic with enhanced strength—keeping the glasses stable without excessive bulk. 

Lightweight & Robust: Combining light plastic with steel’s structural integrity delivers a balanced feel—robust enough to resist deformation, yet not adding undue weight. 

Ergonomic Fit: These temples can be molded or curved ergonomically to match ear contours—reducing pressure and friction for all-day comfort.

3. Blue-Light-Blocking Lens Features
Filtering Mechanism: Such lenses reduce harmful blue light through two main approaches:

A surface coating that reflects blue light.
Embedded blue-light filtering agents within the lens material. This dual action effectively reduces blue-light energy to mimic natural light—easing eye strain.

Effective Range: High-quality blue-light-blocking lenses typically filter wavelengths between 400 nm and 450 nm, which are known to contribute to retinal strain and fatigue.

Additional Enhancements:
Many versions also include:
UV protection—shielding against ultraviolet rays.
Aspheric/non-spherical designs—improving clarity and visual comfort.
