Opsales Polarized Black Metal Clip On Flip Up Grey/Gray Sunglass Lenses, Large Square, 64mm Wide X 56mm High, 147mm Wide with Bridge

Very handy. I keep a spare pair of these in both cars for days with a lot of glare.VALUE - For a pair of glasses that are less than $20 pretty good. For comparison my wife paid $200 for a pair of custom clip-ons at her eye doctor.MATERIALS - The protective lenses are thin but the metal clip is sturdy. They look like they would scratch easily so we store them in the overhead sunglasses compartment of the car and have not had any problems.EFFECTIVENESS - They do a good job cutting glare. They are great for days days when we have a snowstorm and there is a lot of glare. They were a lifesaver coming back from the eye doctor when my pupils were dilated.SIZE - Very useful. good coverage for even large glasses. I have a large pair of aviators and my wife has oval shaped glasses. A nice feature is that in a pinch we can both use them while we are driving.UTILITY - My wife and I both have glasses that tint in the sun but that feature does not work in the car. These are perfect for that since we do not have the same size glasses.

This is the clip on to buy if you have large format glasses. They are light weight and well built.

Not Bad, but, does not flip up high enough. Lens stay in the way and are in your view when flipped up.

I have used several other clip-on sunglasses for many years. These have been damaged by falling because of clip-on fumbling or clip failure or having the lensemounting or lenses damaged by storing in soft cases in a shirt pocket when not in use. Finding the right size and the desired gray color became a problem locally.When ordering 2 pair of these clip-ons, the price seemed higher than I liked but the availability, the correct size, and the color allowed me to go ahead.I ordered 2 pair to have a spare and to reduce the shipping cost per pair. I wondered how the glasses would be packed to protect them during shipping.Each pair of sunglasses came with a hard transparent snap-open plastic case with a formed mounting strip on which the sun glasses were clipped on with theirown clip inside the case. Not a bad way to ship but a great case for carrying the clip-ons in most any pocket when not in use. A slip inside the case says " Made in USA" and that there is a lifetime warranty on the clip-mechanism.

These clip-ons work ok, but they fall off easily, get smudged easily, and flip down all on their own when I want them up, and they do it all the time, to the point of being very tedious and annoying. The shading of the lenses was nice, but in the end, it just proved to me more trouble than its worth. I just tossed 'em.

Bought these for my 86yo father. He loves them. They are easy toget off and on. Flipping them up and down is also easy. His frames areon the larger side and these fit perfect. Even goes over edges a little.His only complaint is they could be a little darker.

Product arrived unscratched nor damaged, place it immediately on my glasses. The attachment was easy. Was concerned of whether it would be a good fit. Just looked at the picture on Amazon and matched it with my glasses. Great fit. No complaints from me

Good value for the price. It fits snugly over my regular glasses, and the flip-up feature is easy to operate. But be advised: this particular model is really, really big. If you don't like the big sunglasses look, opt for something smaller.
