Mens Polarized Photochromic Sunglasses, Aviator Sport Driving Sunglasses, UV 400 Protection with Large Metal Frame

I needed glasses for bike riding when I start out in bright sunlight and come home in darkness. The color distortion is weird, everything looks normal, except reflections off car windshields and puddles in the road look mellow yellow. I feel like I’m living in an alternate reality, but for me it’s kind of delightful. Not for everyone, apparently. These photochomatic lenses need ultraviolet light to darken. If you are wearing them in a car, the safety glass in the windshield has plastic imbedded in it which, besides keeping the glass from turning into deadly shards if it’s broken, but it also blocks ultraviolet light. Your glasses may not darken in the car, but the polarization will still work. This is more appreciated in a car because you may be traveling for a long time behind a vehicle that’s reflecting chrome back in your eyes, and without polarized glasses, some people get migraine headaches. Not so important on a bike. Yellow is better when the light gets darker because it blocks blue light (somewhat) and allows better night vision.

The glasses are nice and actually get darker when in the sun. Seems to be a good value.

These are lightweight, comfortable and inexpensive. The polarization is a plus. However, they do not darken enough in bright sun.

Nice but the lens scratch easily

The photochromic effect is slow to darken with UV and bleach with IR, but this is true for all glass photochromic devices. I like the polarization to eliminate glare, the small uv light to demonstrate the darkening, and the test strip with the invisible picture. The glasses could be worn at night as they are mostly transparent without UV light.

These look good and are comfortable to wear, a good value for the money. But, they don't have the photochromic effect anywhere near to my old pair of Ray Bans, nor a pair of prescription transition lenses. They don't change much at all between indoors and outside in bright sun. So after a couple months of wearing these, I'm of the opinion the photochromatic effect is non-existent, so dropping this to 1 star rating. The advertised photochromatic effect is why I bought these in the first place.

The other reviews were accurate, in that the glasses don't change from light to dark sufficiently, and the coppers might make out my pretty mug from wanted posters :) I wish I had a wanted poster but without the reprucrussions...quite the conversation piece when having guests over for the holidays. I'll stick with my Ray Bans which are gradient fading dark to light top to bottom. They're nice because I can see clearly indoors with them, and got them for around $150. Serengeti glasses are also excellent, with photochromic action adjusting the tint for the incoming light.

I have not yet used these. I bought them for a beach trip which is still a few weeks away. I was shocked to get them so fast in the mail. Not even 2 days, and I do not have prime shipping. I will try to update this after I do wear them a bit. Unboxing: First I noticed it came in a very nice box. Fairly soild. Inside the box (pics included), I found the sunglasses, a cleaning cloth, a soft bag, a thank you card, instructions for care, a small flashlight that I believe is a blacklight (though I'm unsure as why it was in the box, none the less my cat and I like this new tiny light), and a test card. I was surprised at the many items. It was more than I'd thought I was getting. First impression of wear and testing transition: I do think they are a bit big on my face, I am female. That won't stop me from using them. I also think sunglasses look weird on myself. These have the classic aviator style. I like the color of the frames. I used the test card to check the polarization, and it indeed worked. I then went outside and tested the transition. It also worked. They did not get super dark in my photos, but the sun is not exactly filling out at the moment. But they did transition as they should. Shipping: As I mentioned, very fast shipping. Very happy about that.
