Excellent. comfortable, good fit, good value, good polarising effect and effective polychromic darkening effect. The glasses start as a light shade, so don't impair vision in low light (even indoors) but are still effective in dealing with the glare of bright sunshine.Bear in mind that the darkening effect is triggered by ultra-violet light so it will not work inside a car, where the glass screens out u/v. However, the polarising is still very helpful. (My pair was helpfully supplied with a mini u/v torch to test the lenses, which showed rapid darkening.)So long as you are not looking for something super-dark to hide behind, these are effective, stylish and great value.

What I wanted was Photochromic glasses, well, they are sort of. I covered one lens and left them on a window sill in the full sun for 30 minutes, The exposed lens did darken but not by a lot. Both darkened and you do get a milder pair of glasses which I find I like. I don't like these black as black sooper coool shades as they are just for image. These are Polaroid and do that well, generally they are nicely made and quite stylish. They come in a stout hard case with cleaning clothes and a Polaroid tester. On the whole, they are quite good mild dark glasses and I think they will do what I want them to do. Decent price and good value not withstanding the Photochromic aspect.

Perfect, stylish, definitely recommend

The Style of the sunglasses is fantastic . They are very light weight plastic and the nose bit is very soft and comfortable . However the bit that I was disappointed about is they come with a shade on the lenses already , thought they eere going to be clear until i go into the open air / sunlight and then start to go darker depending on the uv ...so I can't wear them at work or on the bus without trying to look like a wannabe young again 🙃 person... a shame but I'll keep them all the same for the days when not in work and it's sunny ...

Not very photochromic

These sunglasses were recommended by a friend, I was sceptical about the quality but after 2 weeks use during the UKs heatwave I can honestly say that these £25 glasses are better than my old Maui Gin pair. The polarised lenses work brilliantly and adjust to light intensity. The frame is strong but at this price I could buy 10 pairs and still be saving on one pair of a designer brand.

Reasonably comfortable to wear. Polarisation effect ok but little photochromic response as others have noted. The lens tint hardly varies from indoors to strong sunlight outdoors. Not sure about robustness of frame. Overall good value for money but would have liked a proper photochromic response.

Blocks out the sunlight really well and helps indoors too as the lighting in my office is quite strong
