Product Features

What are the photochromic lens?


Photochromic lenses are made of many lens materials including plastic, glass or polycarbonate. They are typically used as sunglasses that conveniently switch from a clear lens indoors, to a sunglasses depth tint when outdoors, and vice versa.

They typically take around 30 seconds to fully darken and approx 2 - 5 minutes to return to a clear state.


Indoor Protective Lens: In the room or at night, the lenses color are basically transparent, the same as the ordinary lenses, like high light transmission performance, relieve visual fatigue,make you see the world more clear.

Outdoor Protective Lens: Lens under the action of ultraviolet light in the sun color, ultraviolet dark color change, deep, shallow light-colored ultraviolet light, isolated from UV damage, anytime, anywhere to protect your eyes.

The advantages of the photochromic lens?


1. Reduced costs – buying a single pair of dual purpose photochromic glasses that can provide vision for both indoors when clear and providing sunglasses protection outside is more cost effective than buying two separate pairs.


2. UV protection - Photochromic lenses provide full protection against the harmful UV rays of the sun and direct exposure to sunlight can cause serious eye problems and in some cases blindness.

3. Convenience - You only need to own 1 pair of glasses for both indoors and outdoors in the sun as opposed to needing to switch between 2 pairs of regular glasses to sunglasses. You only need to remember to take one dual purpose pair of glasses with you as no doubt at some point we have all forgotten to take our sunglasses out with us only to be caught out by the glare of the sun or even left them behind never to be seen again.


4. Eye Health – Reducing your exposure to the suns harmful UV rays can lower the risk of cataracts or other eye/age related problems
