I love these contacts. So in terms of comfort, I'd say they are slightly less comfortable than my normal contacts (they irritate my eyes very slightly but it's not as irritating as say, circle lenses). In terms of vision, sometimes at night in bright light there is a slight purple haze occasionally but overall I see great with them on.
In terms of coverage- I have medium brown eyes, and they are clearly purple with the contacts in.
10/10 totally recommend them! Super cute, gives you magical, ...
