What is a photochromic lens?
Let's start with the etymology of the word "photochromic" which comes from the Greek "photos" meaning light and "Chroma" meaning color. So, photochromic simply means to change color depending on the light . Compared to sunglasses, photochromic lenses darken or lighten depending on their exposure to ultraviolet (UV) rays. They are clear indoors and darken quickly in the sun outdoors when subjected to UV radiation and brightness.
Photochromic lenses thus easily adapt to your environment and protect your eyes from brightness and glare.

Varionet photochromic lenses are:
- Made of polycarbonate, a highly impact-resistant and lightweight material
- Equipped with a hardened or "anti-scratch" treatment
- with traditional anti-reflective treatment for added comfort inside
- Grey: lens color most suitable for emmetropic presbyopes because there is little distortion of the light spectrum
- Lenses that react to UV and light, protecting you from UV and blue light by 99%
- Near vision lenses with Varionet technology (clear vision from 30 cm to more than 1 m)
- Perfect for all indoor and outdoor proximity activities!
Please note:
Photochromic lenses are not recommended for people who often change environments. In general, they darken quickly outside but take longer to return to their initial state when there is less light, up to 5 minutes depending on the case.
