The glasses I am presently wearing have interchangeable lenses. That works quite well, but I don't always have the time/desire to be changing lenses. So I'm wondering if the glasses with light sensitive lenses work for anyone? I'm specifically looking at the Tifosi "fototec" lenses. Has anyone tried these? Do they perform as stated? If not, I'll stick with changing lenses. My eyesight is far from perfect (darn those aging eyes!!) so I need eyewear that is dependable. I often commute to work, and the light conditions are so changeable. I want protective glasses/lenses that I can depend on.

TIA!
