The glass is plastiky and the Photochromic Lens is not workingAlso it doesn't fit for who have medium to large nose

Great set of glasses. DO NOT clean them in hot water. Use the cloth that comes with the glasses. The photochromic lenses darken and lighten well too. I created a video to demonstrate to others like me how fast it changes and how dark the lenses get. Enjoy.

Works great for lots of MTB scenarios. The clear lenses get reasonably dark when exposed to sunlight, but for direct sunlight you'd want to swap in the dedicated shaded lenses. The larger surface area of the lenses is also good for cycling at speed to reduce the amount of bugs and dirt that can slip past the glasses into your eyes which I appreciate.They also fit well with my full-face helmet so if you don't want to spring for a nice set of goggles, these are a good alternative.Swapping lenses is reasonably easy, and I've done it a handful of times. I worry slightly about the longevity of friction-fit plastic pieces, however - the nature of this sort of system is that eventually it will wear out as the little tabs have to flex and slide into their sockets - but it has held up so far.The included hard carrying case is a nice touch as well and overall I'm pleased with how these have worked for me.

definitely value for money, very good fit.

Photochromatic lenses work great! Ear pads could be softer

Work great, easy to change lenses and very affordable.
