Photochromic glasses, also called transition glasses, turn dark in the sun and clear indoors. One pair works as your daily glasses and your sunglasses, which suits Pakistan’s strong sun, bikers, students and anyone who moves in and out all day.
How photochromic lenses work
The lens contains molecules that react to UV light. Outside, UV light darkens them. Indoors, with no UV, they return to clear.

Frequently asked questions
What are photochromic glasses?
Photochromic glasses have lenses that turn dark in sunlight and clear again indoors. They react to UV light, so one pair works as both normal glasses and sunglasses.
How long do photochromic lenses take to change?
They usually darken within a minute or so in strong sun and take a few minutes to clear fully indoors. Cold weather makes them darker, heat makes them a little lighter.
Do photochromic lenses work inside a car?
Usually not very well. Most car windscreens block UV light, so the lenses stay light inside the car. Drivers who want dark lenses in the car often keep a pair of sunglasses as well.
What is the price of photochromic glasses in Pakistan?
On ROSHNEY, you choose a frame, which starts from about Rs 1,000, and add the photochromic lens when you order. The full price shows in the cart.
Are photochromic and transition glasses the same?
Yes. Transitions is a brand name that people use for all photochromic lenses.
