I was not expecting much for 3 pairs of glasses under $10 but I actually got more than I intended.
I have not had them long so I can not attest to durability, but they are comfortable, and to my surprise all the lenses are really nice and clear.

My sunglasses and safety glasses tend to produce glare and strange reflections of light especially if they fog up a bit, these do not do that. So I see really clear and feel really comfortable in them.

Now the reason 4* not 5* is the fact I expected them to be comfortable at speed, the glasses I have now not made for riding let way too much wind into my eyes when going faster than say 40mph. More expensive riding glasses had the same foam rings around them as these, so I figured that feature was designed to keep wind out of your eyes and protect them a bit better.

It seem's at least for my face, that is not the case. These are good up to maybe 45mph then wind just starts pounding my eyes and I have to squint and then over 60mph its almost impossible to see with my eyes watering and straining to see.

So I can not use them for everything, but I do feel that I got my moneys worth for them and they are great for small trips up the road where I will not hit highway speeds.

Despite reading several reviews stating that these glasses were fragile and didn't keep the wind out as advertised, I couldn't resist the cheap price and figured it was worth the gamble for 3 pairs of glasses. They arrived within a couple days as advertised. Each in a separate bag within the package, all arrived in good condition. There were no problems with the foam around the perimeter of the frames as some had mentioned. I've been using them regularly for a couple weeks and so far am satisfied with my purchase. I haven't tried the yellow ones yet but the dark and clear work well. They fit my head snugly. They are comfortable to wear for an hour (the most I have ridden with them so far). The foam helps to keep the wind out of my eyes, but as expected, some will still get in. It's an improvement over my wrap around regular sunglasses I have been using. If it's hot, the foam makes me sweat a bit around my eyes. Not a big deal. You can't expect something pressed against your face to keep the wind down and not do that. I can pull them away from my face for a moment and the sweat goes away almost instantly. The dark glasses are plenty dark and definitely keep the sun glare down. No idea about any polarization. I doubt it at this price. The clear lenses are very clear. Better than the cheapo harbor freight safety glasses I was previously using for night riding.
I recommend these glasses. For those reviews that said they break easily, I dunno... maybe you just have a big head. If mine break I'll certainly edit this review but so far I am pleased. For the price to get three pairs, you can't beat it. Go for it.

Air can still get in because the cushion is not one continuous pad, its a bunch of smaller pads in a line. But 100x better than no classes.

I haven't tried the yellow as i don't really ride at night, but the shades and clear are great. They actually don't look bad when worn either. They resemble some cheaper sunglasses; they don't look like safety glasses.

I like them well enough, and they get the job done. But because of the space in the pads, air does get in when they are not pressed against your face. So your eyes can water some still. If I were to do it over, I would pairs with one continuous pad. But these are good enough that I am not willing to mess the return and searching for another set. Plus for the price, they are nice.

These glasses are excellent. This is actually the second time I have ordered them (I wore the last set out-the lenses were still good but the rubber came off). The original ones are still good except for one pair (don't remember which one as I put them away for spares) but I have had them for over a year so I am happy with that. They offer great wind protection. They are scratch resistant. The dark lenses are perfect for sun and they are polarized and no glare. I use the yellow ones in fog and when I am driving at night (they are the perfect tint for this, not too dark to see while protecting eyes from headlight glare). Use at your own risk but they work great for me. I barely wore the clear ones but I always kept them on me just in case I needed them for night or one of my buddies needed to borrow a pair. They are mandatory here in VA so it is always good to have a spare or two. I could have re-glued the rubber back on buy honestly at this price there was no need and you can buy two sets and carry extras all the time.

Great price.They feel good and look good. Can't complain
