I wear glasses, have done for over 20 years now but mine are reactor lights so they go dark the minute I step into daylight
Did you manage to find polarized photo chromatic prescription lenses?
Only ones I could find are Drivewear by Transisions. They are good but never go clear, even without sunlight they have a yellow/brown tint.
I found Asda to be good value for them as they charge an extra £50 for the Drivewear or regular photochromatic lenses.
