YIMIPolarized Photochromic Driving z87 Sunglasses For Men Women Day and Night safety glasses

In full sun glare off new snow (think snow blindness in nothing flat) these glasses crank down to coal-dark in seconds. I own several pair of expensive Ray Bans, but these have become my 'go to' sunglasses.

They are good I like the price, I love them when driving.

Try out for night driving and it help a lot , clear and cut off oncoming headlights, comfortable for long wearing. Recommend for those driving during night time. In the day time , it is clear and have sun protection.It is polarized but not too much on photochromic.

The glasses look good and seam to be well made. They have a light tint out of the box but don't change. Not dark enough during the day and too dark at night. Ad claims z87 safety glasses but nowhere is z87 on lens or frames. Not sure about uv protection but when facing the sun my eyes burn. Would not recommend

They don't fully function as advertised they are not polarized, they even come with a little cartoon to test and they don't pass their own test. I kept them because they do look cool and become a little darker with sunlight and help with cloudy, hazy conditions, but they are not fully polarized and don't help with glare of lights at night.

They are very comfortable and light and are very effective at reducing glare.

The polarization doesn't last and the little rubber nose pieces fall out

I have been hard on sunglasses and there's no point in spending a fortune on them. These are comfortable and do the job.
