hi, I just heard about these contact lenses that can change your eye color, or enhance them. Does anyotne have these? If you got green enhancers, and you have grey-blue eyes, does that mean your eyes would now be an awesome blue tinged green? Or vice versa? If you had grey-blue eyes, and you got a really striking blue color, would your natrual color be dominent, or the contacts? Just wondering 'cause I think it would be fun!
