Rapid Eyewear‘Vogue’ Black TRANSITION OVERGLASSES SUNGLASSES that Fit Over Your Glasses. Will Go Over Spectacles up to 140mm. For Men & Women. Darken with The Light from Cat 1 – 3. UV400 Protection

Work outside but no too dark for inside.

Leider musste ich feststellen, dass die Gläser sehr scharfkantig sind, Verletzungsgefahr.

Don't seem to be photochromic to much ,hardly any change anti glare works fine

I ordered these to use after eye surgery, unfortunately they didn't go dark enough for me. They are rather large but seemed quite comfortable and are less obtrusive than the full frame ones so may be ideal for anyone who doesn't need really dark lenses. They change really quickly too, which would have been really useful.

These glasses do exactly what they say. They go darker in sunlight and return back to normal when out of the sun etc.They help by cutting down the brightness and glare within the home and also when your shopping as the lights always seem to be very bright within stores.

They are lightweight, react well when walking from bright sunlight into shade. The side pieces are helpful. I think it is a well designed product that is comfortable for long distance hiking. Would buy again.
