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

I ordered the Green (Day) and Yellow (Night ) kit. Both came in their own hard clear plastic case and with a black pouch slip in style case.Be sure to measure your glasses before ordering and then order the right size. Don’t get mad if you skip this step and blame the glasses for your lack of effort. They do not fit my glasses perfectly. No clip on sun glasses ever have. They do fit pretty darn close.I can confirm they are polarized.How do you check this? It is easy. Before you clip them on your prescription glasses go outside, not while you are driving, and look for some reflection like in a car windshield or in water. Hold the sun glasses, (again not while they are on your prescription glasses) in front of your eyes and look through them at the reflection. While looking through one of the sun glass lens and rotate slowly in a circle so that you always can still see the whole lens. Do it as if it was a quarter and you are rotating George Washington upside down. At some point if the lens is polarized the reflection will become darker. You can also test this with a LCD computer screen or smart phone screen without bothering to go outside. The polarization on the yellow ones is much more subtle than the green but it is there.Do they block UV rays as advertised? I have no idea, I can only assume they do.Overall they are a great pair and work as advertised. I would buy these again.

I'm in my mid 50's, and my night driving has deteriorated over the years to a point where I really hated driving at night. I had lasik done many years ago, and halos from oncoming cars always really bothered me. But, with age, I also saw more reflection issues coming from street lights and headlights.I accidentally stumbled on yellow glasses to improve night-time driving but was skeptical. But, at this point, I was desperate. These had a good rating, and I could attach them to my eyeglasses. The price was reasonable, so I figured I had nothing to lose, and possibly much to gain. I measured my eyeglasses and purchased these clip-ons and they fit very well. And, then I tried them in different situations. Here's what I found.1. Nighttime driving with no rain with streetlights and lots of oncoming cars - they work extremely well. You do have to get used to them - as the yellow tint makes everything darker. All the white light and reflections turn yellow. But, the reflection is cut down dramatically.2. Nighttime driving with rain - I found it difficult to see when the rain was coming down steadily. Because of the tint, I cannot see the road well when it rains.3. Nighttime driving with no street lights - Since the yellow tint makes everything a bit darker, it's harder to see, so I don't use them in this scenario.Overall, I am very pleased with them, as most of my night driving is in an area with lots of lights. And, because they are clip-ons, I can easily flip them up when the circumstances change (rain or no streetlights/oncoming headlights). They are a very inexpensive solution and I'm so glad that I came across these!

I bought the black & yellow in the 59x42 largest size and they fit my glasses perfectly. They're not heavy and feel just fine. Just took a walk to the store about a half mile away on a bright sunny day (one of few we've had lately), and the black pair cut the sun and glare just fine. They are unbelievably well packaged, each with their own outer slipcase where the glasses slide in from one end, and then their own hard plastic snap-shut case. For my needs and for the price these are great clip-ons that work as advertised. Shipping was fast as well. I thought at first the pair of cleaning cloths had not been included, but found them folded at the bottom end of each slipcase, so a perfect five-stars from me.Edited same day as the review above, but now at night. Tried the yellow clip-ons and found them to be virtually useless in cutting down the light diffusion/aura/haze around streetlamps and oncoming headlights. Of course, there was a light yellow tint to everything, but as I flipped them up and down from my regular view to the tinted view repeatedly I found no reduction in light diffusion at all. Tried the black ones on again to check the diffusion and actually found them rather effective. Of course, everything was darker, but as I flipped them up and down I really could tell a marked reduction in the diffusion factor with headlights and streetlamps. Wouldn't necessarily want to drive with the black pair at night; they're too dark to be comfortable with. But for cutting down glare they are effective for both day and night viewing. Thus, I am deducting a star and my review now has 4 stars. The various packaging pluses still stand, but the actual product (the primary reason for the purchase), at least with the yellow clip-ons, needs some work.

These clip-ons were perfect for my rimless glasses. The spring mechanism that holds the clip-ons to my lens is easy to use and the actual contact points are coated to prevent slippage and marring of my lens. They also flip-up which is great if you're driving into a dark parking garage on a sunny day. I've read some other reviews with complaints about these clip-ons not fitting certain types of glasses. If you follow the sizing instructions provided on the product page you should be OK. However, there does seem to be a limit on how thick your actual lens or frames can be. My glasses are only 2mm thick. The spring mechanism seems like it can spread up to 5mm or 1/4". If your frames are thicker than 1/4", these clip-ons probably won't work for you.

Anuncian como si estuviera fabricado en Estados Unidos, en realidad es 100% de elaboración y garantía de calidad China.Cumple con lo ofrecido en la foto, quién sabe con el proceso que dice como están elaboradas.

It came earlier than advertised. Each in individual cases, impresive!Both lenses advertised as polatized, only grey lenses are, driving yellow lenses are not. Not worth the price.

These worked, fitted well and held on during various activities. I would recommend.

the colour is great ,that is about all .The clip is week and useless what a waste of money

well packed and provided with hard and soft casing for the glasses.
