What are Photochromic Lenses?

Photochromic lenses, also known as photochromatic lenses, are a type of glasses lens that change colour depending on the amount of UV light they are exposed to. In bright sunlight, these lenses will darken to protect your eyes, but when you go inside or the UV light decreases, they'll turn back to clear, allowing you to see normally. This means you only need one pair of glasses for both indoor and outdoor activities, making it super convenient.

How Do Photochromic Lenses Work?

Photochromic lenses have a special light-sensitive substance in between their layers. This substance is usually made of both organic and inorganic components. When exposed to ultraviolet (UV) light, the photochromic molecules in the lens change shape and darken the lens. But when there's no more UV light, these molecules go back to their original form and the lens becomes clear again. This whole process happens continuously as the lenses adjust to changes in lighting conditions.

What is the difference between photochromic and transition lenses?

Photochromic and transition lenses both refer to the same thing - eyeglasses that can automatically change from clear to dark (and vice versa) when exposed to sunlight. 

Can I use Photochromic lenses for driving?

Photochromic lenses can be worn while driving, yes. One pair of glasses can be used for both indoor and outdoor activities, including driving, making them more convenient. The lenses adapt to shifting lighting conditions, lowering eye fatigue and enhancing driving visual comfort. The majority of photochromic lenses also provide complete UV (ultraviolet) radiation protection.

The response time of photochromic lenses can vary, and in some circumstances, they may take several minutes to fully darken or lighten in response to changing lighting conditions.
