I wore daily wear lenses until they were discontinued. Since I had to change lenses, I decided to try disposables and they were available in colors, too! I'm a blue eyed blonde (like many in my family) and always wondered how I'd look with grey or green eyes.
I tried the accuvue transparents and opaques. The transparent ones (aqua) were kinda cool - enhanced the color I had, didn't change it really. I would get them again. The opaques are another story!
What I was not prepared for was the effect of looking thru colored lenses!! The grey ones gave the world a slightly hazy look and didn't do much for my appearance. The green ones make me feel like I'm underwater and looking up at the sky, but I'm told they look very natural on me. Both are annoying when trying to get a clear look at something - I find myself tilting my head (as if to look over the rim of reading glasses) in order to get a clear view of whatever I'm looking at...
I'm a -5.75 and order online (1800contacts). Somehow they mistakenly sent me +5.75 in the opaque green!

I never paid much attention to the + or - before, so I thought I was going crazy until I compared boxes and noticed the error. (1800contact was VERY nice about the mistake and replaced them right away!)
