Global Vision Eyewear Men's Kickback 24 Sunglasses with Photochromic Color Changing Lenses

Great glasses. No need to change if on a bike and sun sets. They also seal well but don't fog

Perfect for motorcycle riding. The tint is nice and dark, even in mid-day sun, and they are super clear when riding at night.

Good product.

2nd pair I have purchased, different model, both claim to have transitioning lenses yet neither actually transition in direct sunlight. I returned the 1st pair and will return these.

What I needed/wanted:- Padded Safety glasses for dusty construction environment (z87.1 ansi)- Polarized (cuts glare, day and night)- 100% UV400 (iow, full UV protection)- Photochromic, so I can use the same safety glasses when going in and out of the sun at a construction site.- Bonus: wear them to and from said work sites on the motorcycle and when pursuing any outdoor activity.I don't know where other reviewers came up with the instructions of putting them in the freezer, then in the sun. If you Google that, it says its "urban legend". There were no instructions of any kind packaged with the glasses... duh....you put them on and wear them, right? But I did it anyway. Freezer - Sun. I live in south-central Arizona where you get boatloads of heat, sun, dust. If you face the sun, they get dark enough. If you then turn sideways to the sun, the one side now goes clear very quickly. Hey, look - If you are outside in AZ on a sunny day, you need them dark; not half dark, not halfway, half-anything.Polarization - these are not polarized. If you rotate them (on or off your head) they do not change. If you rotate them with another pair of polarized glasses behind, they should go black.... they don't. They aren't polarized. I don't have a way of checking other product claims (UV 100% protection), actual safety standard adherence.PRO: they are super comfy, lightweight and look great. People (all wearing safety glasses) said those are cool looking, where'd you get them?CON: Not polarized, transition/photochromic action is too weak, whether you freeze them or not. There is one cautionary statement on the box containing the glasses, to the effect: they may not work as well above 104 degrees F. This may mean: Don't keep these in your car on a sunny day. Dude - In AZ its over 104 every day starting in mid May for 4 months straight - temps in your vehicle will easily exceed 130 and melt stuff!!Anyway - I like these glasses...no, really. But they just aren't for me, especially advertised as polarized, but not. Good thing: Made in Taiwan - don't see that everyday, anymore.

Very nice motorcycle glasses. When they change color is great. Like them alot. Did not fog on me. Well worth the money highly recommend buying.

Works good
