For me, this pair of circle lens was more of an enlargement than a color change. Since my eye color is dark brown, the circle lens color blended well with my natural eye color. The size is perfect because you really can't tell that I'm wearing circle lens and the comfortable-ness was great; I didn't have irritated or dry eyes. However, I do recommend wearing them for less than 8 hours as the instructions say. I usually wore them for 4-5 hours.
