ROCKBROS Photochromic Sports Sunglasses for Men Women Cycling UV Protection

I bought these mainly for cycling and other outdoor activities. They fit extremely well and the optics are spot-on. The weight is among the lightest I’ve ever worn. I rate them 5* and will definitely consider getting a pair for my wife. They stay on my face very well as the temples are embossed with silicone (soft).

I've never felt a need to pop for photochromic cycling glasses before. If it was sunny I wore dark glasses of which I have several pairs. If cloudy, clear protective lenses, like shooting glasses. Occasionally, if the conditions were right, I'd wear amber lenses like I was skiing moguls on an overcast day. But when I saw these photochromic lenses from RB I had to give them a shot. Why? Price. (I bought these glasses, didn't get them for free to review). But it wasn't just price; it was the fact that I have other products from this company that I like very well. RockBros is more than just a bargain brand. The glasses arrived in a bombproof zippered case. I took them for a spin right away, a bright, sunny day in the desert. My eyes are a bit light sensitive but I never felt the need to squint, the lenses were dark enough to protect me from the glare but not so dark I couldn't see the data on my Garmin Edge. As for wind protection, what wind? My eyes were perfectly cocooned. I have a broad nose bridge but the nose piece accommodated me nicely. The glasses are featherweight, but not in any way flimsy; snug but not to the point of causing soreness above the ears. In short, I love these glasses and wonder why I waited so long to join the photochromic fray. I would have been well satisfied if these glasses had cost 2 or 3 times what they did. As for longevity, time will tell. But on that score I didn't pay $150 for them, either. Keep up the good work, RockBros.

The Rockbros Photochromic sunglasses are a great entry pair of cycling glasses. The plastic frame is very light and slightly flexible making them comfortable to wear. The lenses themselves do shade up quickly once exposed to either strong or direct sunlight. I wish the sunglasses had a vent at the top of the lenses to provide a little ventilation as on very hot days, they have fogged up a little.

I wanted one pair of glasses that would function for sun protection and for wind protection and these glasses did exactly as they were advertised. I live in Florida and truthfully the sun protection wasn’t as good against the super bright Florida sun, but I was traveling to Alaska to chase the Northern Lights. These glasses were great during the day in Alaska, but most importantly to me was the use at night. Since they were clear in the dark I could wear them for night sky viewing and my eyes didn’t get cold against the wind. Great purchase!

The lenses is not bad. But in general it’s not looking good for my face.

They looked good and they fit me well (although they tend to sit a bit high on the face, even after adjusting the nose pad), unfortunately the temples are straight and long, and they would end up touching my helmet (Fox Speedframe). This in turn would cause the glasses to either slide forward away from my eyes, or to tilt up away from my nose. If they had curved temple tips, they would have been quite good for the price.

I bought these sunglasses last year. I ended up by biking in them, running, and doing most of the work in the yard. I like them and bought another pair for my wife.I measured how Illuminance changes with time after exposure to sun. From the attached plot it looks like the attenuation is about 2 and happens in about 20 sec. It was measured in sunny late afternoon, and max is 65 klux, less than usually cited number of 100 klux. So, the attenuation might be stronger in a noon sun.Addition Aug 3, 2024: I measured it (again with Android app Light Meter) in steady state. Indoor (200-1000 lux) the sunglasses attenuate by 1.3, outdoor on sunny day from 2 (in shade) to 3 (direct sunlight 100 klux).I compared them with three "no name" sunglasses. Those give the same attenuation in all conditions, and it happens to be quite different, 5, 7. and 8.Conclusion: these sunglasses attenuate much less than "normal". Probably, it could be a problem on a beach, but I still like them very much for walking, running and biking.
