Here's a picture of me wearing the lens in artificial, natural and flash light here: http://i63.tinypic.com/x1hjb7.jpg
The circle lens is not very enlarging, but it does help define your eyes and make it slightly bigger.
It is a medium-dark brown color that slightly lighter than my natural eye color under artifical lighting(I'm Asian). Under natural light, the color is a bit more noticeable, and it is the brightest under flash or direct sunlight.
Like the previously review said, there is a hint of green in the lenses and the gradient blends in perfectly with my natural eye color. I wore it for about 7 hours and there had been no discomfort or redness in my eyes.
To be honest I am looking for a lens that is brighter than this one, but the description and photos from klenspop shows the color of the lens exactly like how it did on my own eyes, and it is comfortable, so I will give it 5 stars.
