regrettable buy. quality is really bad with construction and the lenses simply aren't very clear or accurate. ordered the 4 pack hoping to use them instead of my bifocals when reading but these will likely cause eyestrain. regrettable buy.

these glasses reflect a shadow of the screen on my cell phone, tablet and computer which is very distracting due to the coating on them.they are fine for paper books but hurt my eyes on electronic devices.

updated review 9-1-22:now the 1.5x glasses are breaking. these glasses are totally disposable and i cant tell if they are helping with eye strain.updated review:after a year, 3 out of 4 of the x2 magnification glasses have broken. i use the x2 pretty much just for looking at my phone screen, which is not a lot. i use 1.5x the most, and on my computer every day. i dont believe any have broken and they are the same design. the weak link is not the hinge, but where the lens side of the hinge point is molded to the lens. i attached a picture. all 3 glasses broke at the same spot.so, i liked how lightweight they were and the price at the time (they were less expensive a year ago) but they are breaking. just the x2's for some reason. i also haven't noticed any great difference in eye strain on the computer.i reduced my review to 2 stars and included a picture of the broken glasses.i found some similar glasses with a much heavier frame. i have been using the x3 version for text i cant read with the 1.5 or 2's and they seem fine. i'm going to try those in a x2. i like these glasses better, they are lighter, but they are breaking.original review:i suggest people always set their review filter here on amazon to (newest). there a lot of reviews here that are clearly outdated because there are a lot of options available now that people were asking for before.i’m giving a 4 of 5 stars for these glasses due to value. they are not high-end glasses. at about $4.50 each, these are very inexpensive glasses. and like most people i have glasses all over the place and cant stand them hanging/dangling from my neck, so i stick a pair hanging on the front of my shirt. but all my glasses still tend to migrate and sometimes end up in a pile together or i can’t find any of them!these arrived very well packaged with each one in its own very basic glasses case. in the package are also two lens wipes (cloth, not disposable alcohol wipes) a glasses screwdriver, a thank you card and a little light (they call it a torch) you can do a silly little exorcise of proving the blue light filtering against a white patch on that card with that little blue light “torch”. there is also a glasses hanger or lanyard included if that’s your thing. i’ve never cared for anything dangling or tied around my neck.i never did that test. it seems like they are trying to cover for something. are we inclined to believe these are a fraud because they are from china? how are we to know that little torch isn’t an artificial blue light and not the type of blue light emitted from the sun or a computer screen? i don’t know if natural or device screen is the same “blue” as an intentional “blue” colored light. there is a yellow tint to the glasses that’s not bothersome, but i read that yellow tinted glasses are blue light blocking…for whatever that’s worth. i’m just trying to see if they change anything for me.so far i don’t notice any significant change in my health or vision, but if there is none, these are still a decent bargain. and that’s what they are designed for, inexpensive readers. with the exception of some very expensive glasses, all glasses are vulnerable to scratching. don’t lay them on the face of the lens and how anyone could think they could toss them loose, unprotected in a bag or briefcase with other stuff without scratching is beyond me. it’s common sense.they seem very flimsy, but i’m not sure they really are. the plastic may be new technology. i certainly haven’t gone out of my way to try to break them and none have broken through regular use. it’s only been a couple weeks though.out of the box, the hinges are extremely tight. the glasses screwdriver they include makes it convenient to loosen them, but i have pretty strong fingers and there were a couple i could barely loosen because they were so tight. i suppose that says a lot about the plastic strength if the screws can be tightened that tight. but even after loosening the screw, these glasses require two hands to put on your face without touching a lens in my experience. other “frameless” glasses i have, have a ridge or a thicker perimeter around the lens so you can pick up by the edge of the lens and not smudge the lens. it’s very hard to do that with these, you have to be purposeful when handling them or you are cleaning them every time you put them on. it explains why they send wiping cloths with the glasses. also, sitting at my computer, there is a window next to me and these glasses pick up reflections from behind and the side making me think i need to clean the lens. that can be a little distracting and i dont have that issue with my other glasses. not enough to make me not wear the glasses though.the temple tips have an almost abrasive or file like serration against your skin. at first i thought this would be an irritant to the skin but its not. one thing is for sure, these glasses will not likely fall off of your face, probably even with some physical activity like sports (for anyone who needs readers playing sports!).i like the totally clear everything except the screws style i bought. it feels like i have greater peripheral vision, even if its just psychological. because of their minimalist design, they are very lightweight.
