The easy view behind me is very useful for hiking, walking my dog and bicycling. Particulary with ebikes adding danger to the bike paths and rarely wanring that they are about to pass at high speed, my glasses warn me when they are coming.
Second pair for me. I use these for late in the day rides when I will finish at twilight. They work perfect.
Fitting in the prescription insert requires a little fiddly skill. A small screwdriver, a fixer's mindset to assemble a two-piece puzzle. My optician, new to TriEye, became my superhero; I thought I would merely pick up the prescription insert (–8 diopter lenses fit BTW), & do it myself. But she loved the concept so much, she put it all together! Now I have prescription bicycle glasses that I want to use in many outdoor contexts.
Excellent riding glasses. Way better than the helmet attached mirror.
