I have very dark eyes, so when I put these on (pink label diana brown), it made my eyes look bigger but not much color change. I am fine with it though since I use these going to work. When I irst put it on, I thought it looked too big actually, so I asked a coworker if my eyes looked unusually big or bug-eyed, and she said it's pretty natural looking. By lunch time it gets a little dry but i always have eye drops with me so it's not a problem. If you have dark eyes like me and you want more of a pop of color, these are not what you are looking for. However, If you want something to make your eyes look bigger and slightly alter your eye color (emphasis on slightly) these can be used, especially in more serious settings like for work. Overall, really nice but gets dry in a couple of hours so just have contact lens drops nearby.
