i am not sure but there is some distortion. i can read items well but i see a curve. also, on the pair ki have clean with my usual wipes, that work, i am getting a film.
my eye dr suggested i get readers so my eyes aren't as strained since i look at a computer all day for work. i bought these because they came in multiple colors and looked cute. i felt like it made everything harder to see, so i brought them into my eye dr for my follow-up appointment. she tried them on herself and said the lens was cheap and gave it a fun house effect (huge relief on my part because i thought my eyes got worse). super cute, but i wish the quality was better. i'd return it if i could, but i threw out all the packaging as soon as i got it.
ordered these to help with glare from lights at night..i expected clear lens with reflective coating on them.. my vision was immediately distorted when i put them on. everything was blurry, so tried them out and drove to the store that evening in the dark and it felt dangerous. i wear prescription glasses and when i take these off and just use my bare eyes my vision was much better than wearing these. these just made every thing worse. so i put my prescription glasses on and then put these over my prescription glasses and boy things were even worse, so in my opinion they are not helpful at all.
