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 are great glasses for Florida cross country riding. I don’t even feel them on my face. I do a lot of night ride where I start in daylight and finish in the dark. In the past I had to carry two pair of glasses with me. One set clear and the other tinted. Now the lens color transitions as needed and I don’t have to worry about it. Gave it 4 stars because they are delicate and can break easily if not handled with care. I usually have to buy a pair every 1.5 years or so because a leg eventually breaks off. They are great for the price though.

I've worn these twice now while biking, once on a 12-mile ride and once on a 25-mile ride. Both times I forgot that I was wearing them. They are very light weight and comfortable. The photochromic feature seems to work well. When I put the glasses on, the lenses were clear, and I noticed when I took them off that they were slightly shaded. They come with a small holder that inserts into the glasses for prescription lenses. Although it seems like a good idea, I only wear reading glasses and do not have a need for this. The holder is small, and I wonder where someone would find prescription lenses to fit it. Overall, I like these glasses and recommend them.

When I first got these, they did not darken much in sunlight so even though they fit well, look nice and have that cool and unobtrusive prescription glasses frame that snaps on, I gave them just one or two stars. I kept wearing them though and I was out in bright sun last week and took them off and noticed that they were very dark!I am now changing my review from one or two stars to 5. If yours are not getting dark give them some time in the sun and that will probably change.

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.

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!

They work good as far as getting dark in the sun but the plastic lenses are not that good to see through for me and I have used a different pair before and I could see ok with them but these made it a bit cloudy and maybe it's because I'm a bit older now
