Sunglasses are a kind of vision care product that is used to prevent damage to human eyes caused by strong sunlight stimulation.

Our eyeballs (lens) absorb ultraviolet rays very easily, and the damage caused by ultraviolet rays to the eyes is invisible. To protect our eyes, we must always wear sunglasses.

Our sunglasses are made of special photochromic polarized lenses.

During the daytime, it can effectively filter the strong light, enhance the visual sharpness, reduce eyes fatigue, and keep the eyes always in the most comfortable state of outdoor activities.



Light Grey Glasses (Photochromic)



Photochromic Technology



This type of lens features a substantial photochromic effect. It is not totally transparent, and its color also changes according to how much it absorbs UV rays (ultraviolet radiation).



Photochromic lenses change in color under different light conditions. They darken when exposed to strong sunlight, which can effectively protect your eyes from over-exposure. Our photochromic lenses will change in color only when exposed to UV rays, which means the lenses won’t change colour while you’re inside of your car or somewhere there are no UV rays.



The photochromic lenses detect the intensity of light change and absorb ultraviolet rays automatically. When exposed to intenser sunlight, they will turn darker and at the same time they offer ultimate blockage against UV rays to keep your eyes comfortable by helping you see more clearly and relieving eye strain.



At night or in dark tunnels, these lenses will become clear again very quick, providing sharper vision and longer sight distance for your eyes to see the surroundings clearly.
