YIMIunisex-adult Night Vision Glasses Night Vision Glasses

- Tinting level doesn't change appreciably in sun or indoor- Lense is not of glass, it is plastic, so its very difficult to keep it clean. Whatever you do, spots remain there.- Not a good value for money

Things I liked about these glasses are they look premium people commented on how good they look they are also very lightweight and comfortable to wear all dayThey are definitely polarized but the photochromatic part I was a little disappointed with never owned any before so not sure what to expect but for me at least they didn't seem to get dark enough in very bright sunlight but on most occasions they were pretty good and being a van driver in and out of premises all day not having to keep taking them off was a bonus because that's how I break or lose so many pairs.All in all I'm pretty pleased with them I just wish they would go darker in bright sunlight to eliminate me from squintingFor that I'm deducting 1 star but I do like them

Disappointed,glasses much darker than expected.Yes they do darken outside but don’t lighten much when back indoors.Wouldnt recommend.

I have read some comments complaining that the sunglasses are not clear enough in shade, or not dark enough in the sun. Maybe other sunglasses are better in either of these situations, but personally I think it is largely acceptable. After all, how many sunglasses are there in the market that are at the same time polarising, photochromatic and anti-reflective? Even if you find them not clear enough in shade (which I think does not do justice to them), the polarisation compensate it very well. And they are dark enough in bright light.They are very light and comfortable to wear, gently curved to cut the wind when you are on bicycle, and looking nice as pedestrian. There are all plastic so that there is no metallic nor glass element that could seriously injure your eyes in case of an accident. Their case is made of soft plastic, protective enough to the sunglasses without being too rigid, so that the case prevent them to break or deform whether they are in a pocket, a backpack or else.All perfect.

These are simply brilliant. I had read plenty of articles in pro-cycling magazines raving about photochromatic and polarising sunglasses that cost well over £100 - some of them over £200. Thought I would give these a punt. I cycle seven miles to work and back each day. The glasses are superb. Lightweight. Comfortable on the nose. Fit brilliantly under my helmet without hurting my ears and the arms fit close to the head (but not too close). So quick to darken and lighten. Rain seems to shrink off them. They never fog. Quick delivery. The smart hard case also came with a little picture enclosed that you can only see with a polarised lens (by way of proof that these are indeed polarised.)

The glasses have very sturdy, metal frames and decent lenses. They don't go too dark in the sun, it does just enough to take away the glare without the feeling of being to dark. Polarisation works well, especially when going from light to dark areas.They've survived a mountain bike accident with barely a scratch and they stayed on my head! Not much more to say, except they go clear enough even in a cloudy day and do a good job of keeping wind out of my eyes. Can't fault them. Good job
