CAXMANPolarized Clip-on Flip Up Metal Clip Rimless Sunglasses for Prescription Glasses

I'm an older person having increasing discomfort driving when there are oncoming headlights in my eyes. I'm still working and I need to be able to commute in the winter, in the dark. It was suggested to me to try polarized sunglasses. I had a big pair of polarized sunglasses (from another company) that fit over my regular glasses, that I had bought long ago for a long drive in a sunset situation, so I tried them out in the dark. While that made the headlights more tolerable, I felt they made the general scene too dark to drive safely, especially on my rural road where there are no white lines at the edge. So I thought I would try a flip-up pair and flip them down when headlights were approaching, then flip them back up when the headlights were past.I was very pleased with the price as well as the fit on my glasses; the flipping is easy to control and works as I had hoped. I was even more pleased to discover that these were not as dark as the polarized pair I had tried first. The headlights are still strong, but I am not blinded, especially if I focus on the right edge of the road, and with these shades on, I can still see the side of the road at night well enough to not need to flip up and down. They came well packaged with a protective case, and they are an essential part of my commuting kit. I sometimes walk into the house forgetting I have them on, so I make sure the case is in my purse so I will have them for my evening commute. I am very happy with the purchase.

Seems to be decent quality. Works well. The directions on how to select the proper size to fit your eyeglasses could be easier. Maybe a chart listing the general range of eyeglass lens dimensions to the dimensions of the clip-on sunglass lens sizes for a proper fit would be useful. I was lucky as the fit was quite good.

It is a good product, it protects from the sun but it is somewhat heavy.

I recently replaced my prescription glasses with new ones, and my old clip on sun glasses were too small. And I found it impossible to find clip on sun glasses from my optometrist and I didn't want to spend the bucks for the new custom made magnetic over the lens type they offered. Amazon to the rescue. I found these Caxman clip-on's and they were very highly rated and after following their measurement guide, I bought the best size for my glasses and they fit perfectly over my new glasses. I'm really impressed. Since I don't wear sunglasses unless I absolutely have to, these will be a perfect low priced solution. And the thing I like best is the flip up feature. I'll be wearing them mostly when I'm out shooting pictures and as any photographer knows, it is impossible to shoot pics wearing sunglasses as it is impossible to get an undistorted view thru view finder. So with these, I just flip them up when shooting and back down again immediately after taking the shot, and I have great protection from sun and glare and my eyes are happy.They are very well made and have ample non scratch coating on the clips that fit onto the very top of the lens to secure them in place so there is no chance of scratching the eyeglass lens. The other great thing is Caxman offers a wide variation in lens sizes and a measurement guide so you will get the correct size ordered. Also, there are about 5 colors available from black, dark black, and others. I got the black and am very happy with that color - they don't darken too much that colors are badly distorted, etc. At 13 bucks, I'm ordering a couple more pair so I'll have them in car, camera bag, etc when I need them.

Very difficult to determine proper size

Better than the ones I used to have. Sturdy-feeling (course I only just got them), flip smoothly & come in a nice case.

Product is easy to clip on and comfortable to wear. lens seems good and I am pleased with this purchase. I like the flip up option when I need to see something without sunglasses but dont want t take them off

These are great. Got the darkest one and they're just right for the intense CO sun.Easy to use, lightweight, and dark.My only gripe is that there is a lot of reflection on the inside of the lenses when sunlight hits it from the side or top. I always wear a cap anyway which helps, but it's still annoying when low angle light blinds you with the reflection from the side.
