YIMIPolarized Photochromic Outdoor Sports Driving Sunglasses for Men Women AntiGlareEyewear Ultra-Light Sun Glasses

In the last 20 years I have been buying name brand sunglasses $200 and higher. I have always liked them for fashion and the optics. I just got this pair and cannot believe how much I like them. My biggest complaint with my previous sunglasses have been they are too dark while driving in my vehicle. I wear them anyway but take them off a lot. This pair is so clear while driving while making everything brighter and still blocks the sun. Then when I get outside they switch to dark. I’m gonna get a pair for every vehicle I have. I love them.

They look good and appear to be well made but they don't darken

Excellent driving glasses. Very effective against glare, light and comfortable.Great quality for your money. This item is second to none of the high end, brand glasses

Do not darken at all. It never turns black only yellow

Doesn't change colors like advertised and everything is tinted yellow and bright

I have blue eyes. So, overcast days are much brighter on my eyes than even sunny days, sometimes. The yellow lenses make it easier to see on rainy days. And since I live in Florida, the rain and sun have a tug of war all day in the summer. The photochromic lenses help to mitigate when the sun is out as well.But here is the really cool part. Wherever white light is reflected, it appears yellow through the lenses. This makes windshields on cars glow yellow (again, very useful on rainy days). This morning, I took out the trash and stepped in a puddle, then a dry spot on my way to the dumpster. On the way back inside, I could see my wet foot print highlighted in yellow from about 10 feet away. That's pretty awesome. It's almost like AR.They are also very comfortable. They are lightweight, and have great nose pads.I also found they are useful for glare reduction when I have 4 monitors in front of me at work. Much easier on the eyes.I'm obviously getting old because I just wrote paragraphs about a pair of inexpensive sunglasses, but honestly, these are great. I'm very happy with them.

OK, first off one should know that all photochromic lenses need to be seasoned to work best. Learned this from the Transitions site. Expose the lenses to full sun for 20 minutes, then take them inside and keep them from any light. For this, I just put them in the case and put that in the box. Repeat for at least 3 cycles and the lenses will darken more than just using them. I found these darken almost as dark as my prescription Transitions lenses. This is better than another non-prescription pair of sport glasses I have. The plus is these are amber colored and polarized as well. The amber helps see irregularities in road and terrain better while, of course, the polarized cuts glare. The amber color makes some reflective surfaces look green, like car windshields, smooth asphalt and manhole covers. Not a drawback but odd at first. This doesn't go away as the lenses darken as the amber color is constant. This could be a slight problem in the dark (the 4 stars) but I never ride my bike in the dark, so I don't care. Add to this the fact that they are curved to protect one's eyes, polycarbonate making them near shatterproof and UV A&B protective and these are the best non-prescription protective glasses you will find anywhere.Update on above after using for several months. What little polarization they had is gone. Also the photochromic part doesn’t work as well either, barely darkens. Because of this have changed my rating to 2 stars. Again, you get what you pay for. Still wear them as they, I hope, are still UVA and UVB filtering but that could be gone. I have no way of checking.

All descriptions given by the manufacturer is good. Very comfortable and protection of your eye is wonderful. I love it
