have purchased these twice. very comfortable reading glasses, don't pinch ears or nose, but they do slide off easily. also screws come 'drilled in' some only half way, they strip easily and fall out on their own after a week or so. easy enough to thread a wire thru but the frames will also break where the arm attaches to the lens. nice cases and come with cloths, but they still scratch easily nice for spares in the car, etc. but don't last long enough for everyday use.
i read reviews before buying, but didn't encounter any info about glasses being too tight. after i tried them on, i searched reviews on tight and found only 2 reviews ... strange. ok, goes back.
i don't know if i got a bad set, but i did not want to try another set to find out. the lenses were only 90% magnified. as you got towards the center and the outside edges, the magnification didn't exist, making wearing these at the computer quite annoying. as i turned my head there were large blurry patches. this is not something that happened with my previous, very similar style glasses, that just didn't happen to be on prime when i ordered these.other ratings look good, so maybe i just got a bad box, but i had to send it back b/c i couldn't work like that.
