Active vs. Passive.
Why traditional photochromic transition lenses are obsolete, and active electrochromic eyewear is the new standard.
The Problem
Traditional transition lenses rely on a chemical reaction triggered by UV rays. This strips you of all control.
- ✗ Walk indoors? Wait 5+ minutes to clear up.
- ✗ Driving? Windshields block UV, so they won't tint.
- ✗ Cloudy day? Unpredictable tint levels.
