as someone who has been wearing plain contacts for 5 or 6 years and is pretty nearsighted i can say that, while weird and a little different feeling than my usual lenses, these are really comfortable and I feel SUPER CUTE. As far as the prescription goes, while it works I can see the edges of the lens at times and they're a tiny bit blurry, but I can see, and am not getting head-aches or anything, which is better than if they weren't prescription at all!
I'm really excited on the color too~ very similar to my natural color so it looks really great
