ROCKBROSCycling 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.

I've had these glasses for 3 yrs. With good care, they do last. Reason for 3 stars is that they stopped being photochromic! They no longer get dark in sunlight!

These glasses are just what I was looking for. They weigh next to nothing, so they are really comfortable and fit perfectly. I like them because when I am riding, I don't want too much tint to the lenses so I can see imperfections in the road and on trails. They darken just enough, which is exactly what I wanted. I highly recommend them.

This is my second pair that I bought for mountain biking. I like these because they start clear so I can use them in low light or night riding conditions. They do a really good job of not fogging up when I start getting hot and sweaty. The tint doesn’t take long to appear/disappear according to the amount of sunlight and they are a surprisingly durable and comfortable. I still have my first pair but after a lot of use and crashes, they have gotten a bit scratched up which is why I’ve bought this second pair. They keep a fair amount of dust out when trailing another rider but some does get past the lenses. If that’s a priority of yours, I’d say to buy something with bigger lenses

Really loved how these glasses looked. I bought them back in March and they broke earlier this month for no apparent reason. When I opened the case the right arm was broken. Only lasted me around 4.5 months.
