I have these lenses in Blue. I have medium/dark brown eyes and they are opaque enough that they actually change my eye color enough that it is noticeable from far away. With little or no makeup, they make me look washed out, but with the right eye makeup colors, they look beautiful. I actually bought these mainly to use for Halloween, when I dressed as someone with blue eyes :)However, the reason why I give only 3 stars is because they make my eyes quite dry, and can be pretty uncomfortable after a long day at work. (I work a 9-5 office job and work with a computer all day.) When I wear them to work, I need to go to the bathroom at least a few times a day to take out the lenses, rinse them with multi-purpose solution, put in eye drops, then put the lenses back in. Rewetting drops are not all that helpful for me.The center thickness is only 0.08 mm, just like my Avaira lenses, so what's making my eyes dryer is either the different material of the lenses or the increased diameter (14.5 mm for the Freshlook as opposed to 14.2 mm for Avaira). In fact, one time I got some clogged oil glands in my right lower eyelid from wearing these lenses, which cost over $300 to treat and left me unable to wear contacts for a month, but I think that was from a defective box of lenses, which the merchant fortunately replaced.
