I bought the prescription colored contacts for a cosplay costume. I usually wear contacts so I really needed something that still allowed me to see. The strength that I ordered ended up being perfect, but the curvature is WAY off. The curve was way too drastic and stood proud from my eyes. So every time I blink they move around and frankly kind of hurt. They work long enough for photos but I wouldnt be able to manage them for more than an hour I was expecting them to have an option to FULLY customize the fit but I guess not. Shipping was very fast though.
