Photochromic Sunglasses

Really impressed. Good-looking, wide, unobstructed view, a bit too high on my face, but maybe that's just my face structure, or it's made for a more bent-down bike posture. Air does make its way in, but it's ok.

Ya'll. I have bought 3 pairs over the past year and while the others were ok, they were all either too dark once in the woods or too narrow and debris got behind the lense into my eye. THIS pair is everything I was looking for.1. Crystal clear view, I mean, couldn't even tell something was over my eyes. Even with the tint once in sun, the vision was not diminished like other tinted glasses will do.2. Coverage is perfect, wide, full eye protection. Nothing got behind the lenese.3. Nose adjustments, I did have to trial and error a few times but lots of adjustability with the nose piece to help glasses form well to your face.4. Lightweight! Seriously, once I got the nose adjustment right, I couldn't tell i was even wearing anything on my face. The top of the glasses did not bump my helmet and they did not slide, even with the sweat and 5 hrs of rocky/rooty/fast trails i was riding.5. I am super impressed with the photochormic lenses. When in sun, they tinted but I couldn't even tell they changed! My hubs had to point it out to me. The view from the glasses didn't diminish at all when tinted.6. Buy these. Just do it. If you need a pair of glasses to protect from debries, and hate the dark tint of sunglasses then these are for you.Note: I use these for mountain biking and that is what I was looking for, a pair of glasses to wear when trail riding that I didn't have to carry multiple diff lenses to stop and change based on light intensity in the woods.

I've been looking for a pair of riding glasses that can provide eye protection and some relief from sun glare. I've been moving away from dark polarized glasses toward lighter tints and clear lenses. This does split the difference pretty well and gives you some of both.These are not getting dark. They just don't do it. They aren't bad - I've got prescription Transition lenses for my glasses and these work nearly the same. When comparing the two, these Rock Bros have a bit less tint when dark, but not too bad. They are nearly 100% clear when not being exposed to UV.They require UV be on them for them to stay dark. If under a visor or generally not getting much UV, that will allow for them to go clear.I'm happy with them so far. I've done about a dozen rides in them and they work. They are plastic, so they scratch pretty easily. But I'm happy to have these to keep things out of my eye and offering a bit of help with the sun.*****Update****** 9/8/21I'm on my second pair. The first pair's frame cracked at the temple when they were sat on. Derp.I purchased the same glasses and can report these work just the same as the original. Again, not getting totally dark/black, but tinted and cuts the glare. I wear these most rides and think they are fine. For under $25, good enough.

Needed these so bad

It's my 3rd pair of sunglasses from rockbros. All 3 was good, lenses were clear and photochromic worked well. My complaint is with myopia adapter. It does not last, and just breaks. Not dropped, not removed, no bump, and during mid ride it suddenly breaks. It is my 3rd pair just because of myopia adapter broke 3 times, not the sunglasses. But they don't have replacement for sale. First one broke when I tried to remove it to clean it. So I thought it was my fault. So I ordered second pair, and after a ride I left my sunglasses in case in trunk of my car. Next time I open the case, and it's broke , inside the case. I thought that was weird, so I order the 3rd pair and this time it just breaks on mid ride. No particular reason I can think of. If you are just using the sunglasses without prescription, this is good sunglass for such a low price. But if you are getting it for rx, look somewhere else.

These glasses are great for cycling. I go on long rides and short rides and these are an essential part of my kit. It keeps the window, bugs, rain, and debris out of my eyes. I really enjoy getting out on the trail or open road and going a long way. Quite often to do that I have to start and end my ride in conditions where lighting has change (sometimes a lot). Having sunglasses on that adjust to those conditions are key. I need eye protection in all lighting situations but do not need smoked lenses in the dark. I do not have the space or inclination to carry two or more pair of sunglasses with me. Enter these wonderful pieces of eyewear. They are comfortable on the face, light weight and aero. They react quickly to changing light conditions and have stood up to all the elements.

As shown in the photo these glasses do *not* darken very much at all. The photo was taken after these glasses were exposed to bright Arizona sunshine for *3 hours* and they hardly darkened up at all.Worthless.....
