CAXMAN Polarized Clip-on Flip Up Metal Clip Rimless Sunglasses for Prescription Glasses

These are the best clip on fold up sunglasses out there. I have been getting this brand for at least 8 years. Sizing can be tricky. I always buy two sizes and return the one that doesn’t fit well. Thin but durable…they don’t slip off.

Good buy

The fit was great and the lense color was nice great look and easy install

Got one to try so I wouldn't have to always be swapping to contacts or wearing an additional pair of eyewear(cover shades) on top of my daily glasses that can fog or cause headaches when worn too long due to additional pressure point with the weight and the arms(temple) of both eyewear. These are lightweight enough I barely notice them when they clipped on and in use, though if you have larger glasses, the weight might be more prominent. They work great in reducing the bright outdoor blinding sunlight, but as with all prescription eyeglass issues; unless you have AR coatings the light refraction is still there though extremely reduced to be negligible. it's not completely removed like when wearing contacts + regular sunglasses but it's more than enough to make it comfortable to drive without bright flashes of light just blinding you out of nowhere. Another great thing is they make it so if i accidentally look too high when sunlight is out and i happen to cross into some direct sun or glare reflecting surface that usually causes "flash blindness", nothing happens as long as i don't stare too long. As for durability, they feel alright considering how lightweight they are and rimless; but only time will tell.

My husband never goes anywhere in the day without them

These are as well made as any clip-ons, but warning: They are not as dark as advertised. I ordered both Cat3 (Grey) and Cat4 (Dark Black). The description says Cat3 "light transmittance" is 12%-17% and the Cat4 is 5%. Both claims are wildly false. Using a high-end digital light meter, the Cat3 transmits 83% of the light, which means it BLOCKS 17%. The Cat4 transmits 70%, so blocks only 30%. No idea where they got their 5% number for Cat4. I have a blown pupil in one eye and need 50% block to be comfortable in bright sun.

Review from my dad who “searched far and wide” for these: Great optical quality, well constructed, very well designed clip-on mechanism, great level of extra darkness, and the extra-wide lenses give good peripheral coverage.

The clip one did not fit because the description was to vague. I was so disappointed I threw them out.

Its awesome! So dark and it fits perfectly on my glasses and stays put!

There was nothing wrong with the clip ons, per say, but they didn't fit the glasses they were bought for.
