nothing against this product itself. its nice and comfortable.but all blue light glasses make claims that have no actual backing. don't really do much.
i can't tell if they work or not; i still get headaches/eye strain while wearing them for work. it comes with a little mini screwdriver (?) to tighten the screws, but it barely fits in the screws to tighten them, so not sure if that solves the problem. the screws come loose really easily so the glasses feel flimsy. i want to think they do help at least some, but i don't know if there's a definite way to tell.
since most of the world has moved to online learning because of covid, i decided to try these blue light blocking glasses so i could potentially reduce any eye strain.starting with the pros:these glasses are pretty stylish, the design is popular and this is one of the cheaper ways to get glasses in this style without having to dish out a lot of money for name brands. alongside that, paying about $17 (at the time of my purchase) for glasses, a carrying case, and a cleaning cloth isn't that bad of a deal.cons:firstly, the adjustable nose pads of these glasses, although being a nice feature compared to an integrated nose pad are not easy to adjust and i still haven't been able to get them to a comfortable position. that's not really the fault of the glasses since it would be impossible to make these fit everyone, but be aware that you might have to spend a decent amount of time adjusting them before you'll feel comfortable wearing them for extended periods of time. moving on from that, i noticed that there is a lot of reflection in these glasses, i can see my pupils reflected and it can be quite distracting. finally, i'll be honest, after having worn these for about a week, i can't say that i've noticed any noticeable difference in how my eyes feel at the end of the day, i should have been suspicious when i didn't notice any orangish tint commonly found on other reputable blue light blocking glasses.overall, i would recommend looking into other options for blue light blocking glasses if you're also looking at screens all day, but these would function as decent fake glasses if that's what you want.
