What is the photochromic lens?

Photochromic lenses are eyeglass lenses that are clear (or nearly clear) indoors and darken automatically when exposed to sunlight.

Transmittance: 80%-18% (80% is light grey colour when in low UV, 18% is dark grey colour when in high UV) 

What is the TR90 Frame Glasses?

TR90 is a thermoplastic material that is incredibly durable, flexible, and lightweight. Frames made with TR90 are extremely comfortable. Since they are flexible, they can bend under pressure and contour your customer's face comfortably

Why must eyeglasses have UV400 protection?

Eyewear with UV400 protection is essential because it blocks harmful ultraviolet (UV) rays, specifically those with wavelengths up to 400 nanometers. These UV rays, particularly UVA and UVB, pose significant risks to eye health, including cataracts, retinal damage, and even skin cancer around the eyes. UV400 protection ensures that the lenses can effectively shield the eyes from these damaging rays, reducing the risk of eye diseases and minimizing eye fatigue and discomfort caused by exposure to bright light. Therefore, it's crucial for eyewear to have UV400 protection, especially for outdoor activities like driving, hiking, skiing, swimming, and more.
