A while back, I got a new pair of lenses from Geocolouredlenses.com . I was excited to try these, since this specific line of lenses has tempted me ever since I started wearing lenses.
What I got was Geo Super Nudy in Grey . They're 14,8mm in diameter, come in wide range of prescriptions and have a really beautiful, simple design.
I have a greyish-blueish-greenish eyes so the middle part blends in really nicely. Even though the diameter isn't that huge, the outer rim is quite thick and gives you very dolly enlargement effect. Wouldn't recommend for those who are after a really natural effect though!
They're also very comfortable, like pretty much all Geo lenses I've ever tried.
