AosBetKMDJG 2 Pairs Safety Glasses Side Shields,Slip on Side Shields, Fits Medium to Large Eyeglasses Frames（2 Pairs Transparent Black）

Purchased many times. Work great.

Especially for the price of them, I must say I am fairly impressed. Granted I did have to modify them a little bit, as I wear completely circular lenses, but still. Having them made of a silicone rubber makes them fairly easy to work with, and they seem pretty durable. I may have to modify them a bit more, to make things physically even, but overall, they are still excellent, as far as I can tell.

I was expecting thicker fabric. I should have read the description better.

Generally speaking it is not good enough, for 4 reasons:1: not a good fit for many glasses types, I have multiple and it is a good fit for only one.2: although it is made in black, it is still transparent. I used both pairs on one glasses to make it block the side light.3: it is not good looking on you glasses, you can only use it in your house to read something.4: vertically, it does not have a good coverage. they could have make it much better.pros: made of good material and probably will not tear apart.

NOT UV Blocking - Tested with a $20 Bill and a DriMark UV Pro flashlight from AmazonThese M-L versions are:* Less stable on my Aviator frames than the S-M version, which is exactly the same size* Easier to attach to the frames due to SINGLE feed through hole vs the S-M's two feed through holes.If you're going to attach and remove a lot then these are better than the S-M version. You'll do a little wiggle to settle them into place after putting the frames on but they seem to stay in place after that if not disturbed. For me the stability of the other, S-M, version is the better choice since I just leave the sides on all the time.

My husband had cataract and glaucoma surgery and is very light sensitive. He was wearing two pair of sunglasses, but still had issues with sun coming in through the sides. With these shields, he can wear one pair of sunglasses and is able to see well enough to finally drive again. He is a very happy man!

An awkward fit on my sunglasses, could be a little darker, but helps a lot!
