I have some Tifosi's with Fototec lenses - the "Light Night" version on the Tyrant frame (they have i think 6 different light sensitive lenses) and they are far from a gimmick for me. I can wear them at night and the middle of the day without having to switch lenses. These ones don't get as dark as some of the other versions but the quality of fit

They protect well against bugs. I've used them in descents at 50-51mph and they protect well from the wind. They don't do much to keep my eyes from itching during allergy season. I use them in the winter, but they will fog if I'm not moving and my eyeballs definitely get cold into and below the low teens.

The Tifosi's are a great value with the quality of the glasses and the price, but if you are worried that they could get lost of broken then they are overpriced. I used to go through glasses about once a year or sooner because they'd get broken by my kids or lost, but I've been really satisfied switching to nicer glasses. I just have to be more careful with these ones.
