I'm used to wearing normal contacts so I was worried about circle lenses but let me tell you, these are SUPER comfortable! A little blurriness at the beginning that fades quickly and I can't see the coloured part when I look around (always happened with other coloured lenses).
They look natural on me (I have medium brown eyes) both indoor and outdoor and they are much softer than I expected (it's a yearly contact, and I normally use bi-weekly).
All in all, I think I'm going to buy another pair in a more daring colour! :D
