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.

Brought for husband who's having a lot of problems with his eyes, they seem to be helping.

I took time to choose what I felt were the right glasses for me, I needed something for driving as well as general use. The glasses don't go as dark as I would have preferred but they achieve was was described. Whilst driving they are very effective in reducing glare and they have now replaced an old pair of amber tint driving glasses which I used previously. I find them extremely comfortable and often forget I have them on. As a result of my purchase I have now obtained a second pair for my son and he is equally pleased with his. I often go to a location where there is a large fish pond in which I have never been able to actually see the fish, with these glasses I am now able to see all the fish clearly so impressed and satisfied with my purchase.

I have had these now for some time, but wanted to be 100% certain before I posted this review.If I wear these glasses for longer than an hour at any one time, I am guaranteed to wake up the next morning with severe headache/ Eye strain! Because of this, I only wear them for driving in extremely sunny conditions (As per the new driving laws regarding the sun) and never longer than one hour at a time!Despite this? They are extremely comfortable!

I use them when sea kayaking so they take a beating these stand up to the job and don't coat the earth.

They may be polarised but they do not darken in sunlight!

The sunglasses are okay, but don’t rely on the photochromic lenses they are very slow to react (if they react at all.

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.

It fit my face perfectly and looks good too.

Like the transition feature. Can wear outside or driving. Great shades. My favorite!

These glasses seem to be polarized okay, but I have worn them in bright sunlight and the lenses do not visibly darken as advertised for being photochromic!

Remueve los reflejos ligeros y atenúa los fuertes. En el mar te ayuda a ver los peces con mucha mayor facilidad por lo mismo de los reflejos. Te puede llegar a remover la vision en monitores, celulares o televisores. Aun no entiendo completamente porque. En el monitor que uso si se inclina la cabeza de cierta manera, se puede llegar a ver el monitor completamente negro.A mi en lo personal se me caen bastante si agacho la mirada.

Ottimo grazie
