Photochromic Lenses: Explore Transitions GEN S & XTRActive Options
Photochromic lenses — also known as reactolite lenses — are a smart solution for people who need clear vision indoors and sun protection outdoors. These light-adaptive lenses stay clear when you’re inside and darken automatically when exposed to UV light, acting like built-in prescription sunglasses.
At The Glasses Guys, we offer a range of premium photochromic lenses including Transitions® GEN S and Transitions® XTRActive to suit every lifestyle.
Enjoy seamless vision in every light with photochromic lenses – dark outdoors, clear indoors.
🌞 What Are Photochromic Lenses?
Photochromic lenses use light-sensitive molecules that adjust to UV exposure, becoming darker outdoors and returning to clear indoors. This built-in responsiveness offers:
✔️ Convenience – no need to carry sunglasses
✔️ UV protection – 100% UVA & UVB filtering
✔️ Comfort – reduces eye strain and glare in changing light
