Hi, I'm twenty one years old and I have been wearing contact lenses for about three months now, I have an astigmatism. I've been having discharge for the last couple of weeks, when I wake up my eyes are almost completely crusted over, I just assumed it was from allergies, however the last couple of days I've been having pain in my eyes and some blurred vision from time to time, yesterday I noticed that the sclera is a grey color and there are spots that look more blue. What could be causing this? I googled and all I came up with was a rare bone disorder(which I don't have) and aging(I'm twenty one)...
