I have light green eyes, which I like very much; however I also like changing up the color of my eyes every now and then. I thought that was cool, and it reminded me of Glitter Eyes, which gave my eye a silver glow (but painful to use), and looked wolf like. I imagine they will last for about a month till you need to replace them. Even though Moonlight was not at all recognizable on my light green eyes, I will say that they are very, very, comfortable.
