Photochromic Sports Sunglasses Professional Anti Fog - UV400 Goggles with Myopia Frame for Running Cycling Fishing

I have had these for around 5 years! For a $30, these are amazing.

Good inexpensive glasses for riding that seem responsive to lighting. I have only used them for a few rides so time will tell if they last. They are comfortable, lightweight, and stay on my face well. No regrets so far.

I bought these as an experiment, and frankly didn't expect to think much of them. I was wrong--they are fantastic. The comfort & fit is excellent, and the high front makes them disappear when I'm on my bike, which is all I use them for. They are very light, and the temples are just the right length to work with my helmet and to keep them perfectly in place. Of course, they look pretty stupid, but I'm not dressing for style on my bike. I had zero confidence in their photochromic abilities, especially after being sorely disappointed by a pair of $220 Julbo Reactiv glasses earlier this year. These Rockbros don't go from clear to dark as they claim, but they do go from near-zero tint to what I'd call a "medium" gray. They are not quite dark enough to ride on a full-sun day in the desert, but in a mixture of clouds and/or trees they are fine. The change is fast enough to be useful, but they don't change quickly enough to adapt to riding into and out of tree shade quickly. However, since they don't really get very dark, they are fine for that. Clarity is excellent, despite the very thin lenses. The included case is nice. Overall I'm extremely pleased with these, and will probably buy another pair for my girlfriend.

These glasses have been the most comfortable ones as of yet and it is my 3rd pair that I have tried in the last month or so. They fit well under the helmet and are light weight but they are wider than what I thought they would have been from the measurements on the photos. I do have a skinny face so it’s mostly my fault. Lol. I only wore them once so not much more I can say. They were very comfortable.

[update after ~7 months] I originally rated these 1 star for not being photochromic, and noted that I'd keep them as light grey glasses because they fit (me) so perfectly that they're the only riding glasses I've ever forgotten I'm wearing. Who knows how long I had these on today? I was completely oblivious to them. The lenses are essentially invisible, and the ugly high frames are out of my field of view. (Everyone else can see them, though :)) And I'm not too big to admit that I was wrong and there is actually a mild photochromic effect. But only mild. And only in direct sun. Given that I forget I'm wearing them, maybe that mild effect is just the right amount. Over the months these have been the only glasses I've worn - my other more expensive and better looking pairs are sitting and gathering dust. The other pairs are optically imperfect; too dark; leave a sensation on my nose or temples or ears; leave a gap above the top of the frame; need adjusting; or any of a number of other problems. I've come back to this review because I came back to the item listing to rebuy it in different frame colors, and my name caught my eye. Turns out I won't buy more colors, because the white pair has a chance that light will reflect off the nose bridge, and I don't like blue. When I break or lose my black/red pair, I'll buy another without hesitation. [original review] Light grey indoors. Light day outdoors. Light grey in the sunshine. Light grey if placed in a box overnight and taken out in the morning. Light grey if one side is covered and the other side in direct sunlight for an hour. These are simply light grey plastic glasses. However, the top of the frame is high, making them disappear to me while riding, are comfy (to me), and in 20 years of serious riding are the first glasses that I've forgotten I'm wearing, so I'll keep them as light grey glasses. Be warned that the high frame looks ugly in use.

I thought it was better quality

I use them for trail running with windy conditions and prevent watery eyes, so you can focus on where to step properly downhill. Lightweight, fits well, you can place them over your cap if not need it.

Óculos muito bom, é leve, lente de boa qualidade. Já utilizei em mais de 10 pedaladas em trilha, bastante trepidação etc e ele se mantém firme na cabeça

Lentes de protección muy adecuados al ciclismo, se oscurecen en relación a ser expuestos a rayos solares; no esperes polarizado extremo pero facilita vision en la mañana o al atardecer. No permiten el paso de polvo o insectos, sellan bien el rostro y no se empañan, lo cual se agradece. Resistentes en relación a marca y calidad de la misma. Mejor opcion China.

Glasses are good though the bridge above the nose is too high - hence they sit high on the face (could be the shape of my face). Otherwise very clear on those cloudy days and they adjust accordingly to variations in brightness. Note they scratch easily so care must be taken after each ride to put them away safely. On warmer days hard riding on single-tracks, the lack of air circulation between glasses and face may cause glasses to fog up.

muy buena protección fisica y de luz
