These lenses stay fairly moist throughout the day, but they also get little uncomfortable at times, but a little blinking or rewetting drops gets rid of that. My main issue with them is that they are INVISIBLE. I have dark eyes, so maybe that adds to it, but the color just does not show up on me, even with a bright light directly pointed at them. It seems like the lenses are mainly clear, with only small bits of color at the edges. Another issue is that they are very large and are probably supposed to enlarge, but because the lens is half clear, it looks very strange with only little bits of green coming out of my eyes and onto the whites. You can clearly see through the lens where my real iris is, which bothers me. :(
