ROCKBROSCycling Sunglasses Photochromic Bike Glasses for Men Women Sports Goggles UV Protection

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 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.

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.

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.

These are extremely comfortable sunglasses that work well on hazy days. I was also impressed by how much darker they became in bright sun conditions. In all, a nice addition to my cycling glasses at a good price.

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.

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.

These are terribly cheaply made, and the "polychromatic" lenses do not work. The quality of the plastic is that of a cheap toy you'd find in a Cracker Jack box, back when they had toys in there, or that you'd get as a cheap party favor for a kid's birthday party. They aren't worth $5, much less $30. They are going to be returned at my first opportunity. Do yourself a favor and avoid these.
