Well, I got circle lenses/colored lenses quite a while ago, but don't wear them daily. I have disposable contacts that I wear everyday, while the circle lenses I use every now and then to make my eyes look more cute. I keep them in a contact case in solution, obviously, but I was wondering how often the solution should be changed??? I've also noticed when I put them in recently they made my eyes sting… why is this? Thanks for your answers~ ^_^
