– MIRYEA Polarized Photochromic Outdoor Sports Safety Sunglasses for Men Women Anti Glare UV400 Protection for Day and Night Driving Cycling Golf Running Cycling Fishing Eyewear Sun Glasses

These turned out to be very good sunglasses. I had doubts before buying them but it turned out that I made the right choice. Smart and adaptive to the light. They darken in bright light and become lighter in a darker environment. I recommend this product!

Comfortable lightweight spectacles. Easy to wear and do provide some sun protection although not a substitute for proper sunglasses in very bright conditions as do not darken sufficiently. I have to wear protection against bright light at all times, so I thought these would be ideal for changing conditions and they do help, just maybe not as good as expected.

Found them fits well. Very light. Excellent price. Can't wait to try them soon.

The photochromic darkening effect is minimal and you cannot do the “test” as is illustrated in the advert. The lenses do not go anything like clear in the dark and not very dark at all in the sun. Polarisation is fine though. The glasses are clearly made by Yimi and not by MIRYEA. I am now worried whether these are proper UV filtering lenses and will get them tested before I decide whether to return for a refund. EDIT - UV test is ok, they do filter out the harmful rays and a pure UV source darkens the lenses well. Natural light causes slow changes and limited colour change as above

I use regularly for sport (running and tennis 5 times a week, some cycling. Skiing etc) They work very well No mist, comfortable, lens adapt quickly to different light Strong and adapt to head face very well (do not drop) Often I use them instead of my expensive branded one when not doing sport as well Excellent value for money

These are polarised & do cut down car windscreen reflections, but as you would expect do not go darker when driving. They do have slight tint & do cut glare a bit, but in bright sunlight normal polarised sunglasses are better. Do work outside car & do go darker but not as dark as dedicated sunglasses. Yet to try out in winter mornings, where I'm hoping headlight glare may be slightly reduced.

Well made and supplied with a soft case. Looks good and seems to meet the UV regulations. However using for driving and cycling there are some slight internal reflections which may be a distraction.

Love these for using when out on my bike,take the glare out of the sun and make cycling a joy.
