ROCKBROS Cycling Sunglasses Photochromic Bike Glasses for Men Women Sports Goggles UV Protection

I bought these glasses for trail running because regular sunglasses are too dark, and I habitually trip over small roots and stones. I also have a habit of nearly treading on rattlesnakes, which blend very well into the dirt and leaves and are almost never in a hurry to move. I need both eye protection and better contrast so I can avoid falling and hopefully will see snakes before I'm right on top of them. These glasses are IT. They fit perfectly, are very lightweight and I can't even feel them on my face. No ear or nose pain. They don't fog up or slide down and most importantly, I can see the trail clearly and the contrast is very sharp. They transition seamlessly from clear to dark and back while traversing trails with frequently changing light conditions. I ran 5 kilometers in heavy heat and humidity, sun and shade today with sweat dripping down my face. These glasses performed very well. I am so pleased with this purchase. To summarize, these are wicked good glasses for outdoorsy folks like me.

Definitely worth the money. They're inexpensive, the lenses get surprisingly dark (darker than my prescription transitions lenses on my daily wear eyeglasses), and what I didn't expect was that there's an insert that you can put prescription lenses in and pop on top of the nose piece. They seem sturdy, and the arms have springs (something I didn't have on my more expensive old uvex and tifosi glasses) and they fit a woman's head! The lenses are clear, they're vented so they shouldn't fog easily, and I was really surprised at how dark they got out in the sun, so I can wear these for day or night rides and have my eyes protected from road debris while riding and they're nice and light.

These glasses are good for the price. The photochromic function is decent to good.The black nose pads and the black hinges are slightly distracting.

These are great when running. Stay in place and quality is good.

These are the 1st pair of glasses that fit my face. I think the nose piece did the trick. As a bike rider, I mounted my rear view mirror to the left arm of my glasses. The polychromatic lenses are clear & work flawlessly. I even got a pair for my husband. Thank you for making these glasses!

For the price point, it's a good buy. The lens do a good job of changing color; an important detail for me because of the change in shadows where i ride while I ride.Here is the catch: Make sure you fold them carefully and put them in the case after each use. Mine lasted a little over 2 years. The weak point is the hinge. The good news is that there is no screw to get rust or fall out. The bad news is that it's plastic and finally snapped. I would not say that I am rough on them, but I have not been as careful as I could have been. Part of the reason why i don't buy the really expensive ones. I would also advise against these for triathlon. Something a little more durable might do well.You need to make the call as to how careful you can and will be with them.Do they work? YesFlexible and adjustable nose piece? Check!Are they lightweight? YesComfortable? For me, yesWould I buy them again? TBD. Maybe if I find a pair that the frames are still good where someone sratched the lenses.

Bought these as clear glasses for motorcycle riding at night. Then I realized they darken in the sunlight. Nice light weight glasses. I would recommend them.

The blue purple ones with the full frame are terrible. The sweat wicks right on the lenses and fog up due to the tight design and no air flow. All the ones without the full frame work great!
