TJUTR Photochromic Polarised Sunglasses Style Cycling Glasses UV400 Protection Metal Frame Sunglasses for Driving Sports Unisex Men Women

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

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

A very comfortable wrap-around style of sunglasses, giving good dust protection (I wear a contact lens) on a gray day these have very little tint, but darken up well in sunlight, and cut out reflected glare. Excellent for cycling but remember they WON'T work in a car as car windscreens cut out UV and it's the increase in UV that triggers the lens to darken.Because of the wrap-around design they are still quite bulky when folded, it's worth have a rigid case large enough to cope with this. They come with a protective bag, lens cleaning cloth, a card to confirm they are polaroid and a UV 'torch' to confirm they are sensitive to UV light (the latter are a nice touch, particularly in view of their modest price)Two nice extra details: the side-arms are sprung and are textured so they don't slip when you get hot and sweaty, again nice touches at such a reasonable price.

These work really well, specifically the polarisation, even when in light mode, making them great for driving in most conditions. I find the time to react to changes in light is fine.
