Very satisfied with the magnifying glasses. They fit perfectly well on my bifocals. Now I can see the smaller print and it is not blurred. They came the day after ordering in good condition, with a case.Great convenience at work, works well with computer screen distance. Only thing with the computer screen it does work more as magnifier compared to how they work as readers for paperwork. They flip up 180 degrees, they make the glasses top heavy so glasses to slide down the nose slightly.Metal clip and comes with a caseLight, easy to stash/clip on maybe a collar when not needed. The storage case is nice when I am actively needing them. I have a feeling the lenses may be easily scratched. I am happy that I purchased them.Me gustaron por lo prácticos que sonThese clip ons were the perfect solution to not being able to read small print as i once did. However, i could of bought a smaller lense fraction of 5 which would have given me the same results..My badSo I have a horrible astigmatism, can't wear contacts. My vision for reading is now worsening, I'm afraid I can't get away with being 29 for much longer... I tried progressive lenses and HATED them, but with the next pair of glasses I only got a little bit of magnification on the bottom of the lenses, but then I have to read with my nose way up in the air. In a fit of desperation, I ordered these clip on readers. They happened to be the perfect size to fit on my glasses. They come in a handy little container. The clips don't scratch or otherwise damage my glasses, and the readers themselves haven't gotten scratched up with regular use for several weeks now. I can read again! My only minor issue is that wearing these makes my glasses a bit top-heavy, so if I'm bending over, my glasses will sometimes slip down. But seriously, for me, these were life changing! So happy with them!Physical dimensions are overstated. The height if the lenses top to bottom is not 1.57 inches it is 1.4. The width is not 2.36 inches, it is 2.25 inches.
