Im badly shortsigted, but with my contact lenses ( or specs ) i can see just fine.
but if i lose them or something .. im almost tehnicaly classified as "partially sighted", so i am useless without my eye wear.
I have a bit of astigmatism too, but its corrected.
Im lucky i guess. One of my friends has really bad eye sight. She wears contact lenses too .. but it doesnt correct all of it .. she has some degree of color blindness .. im not sure the name of the condition .. she cant see pale colors properly, like if someone write red pen on white paper it cause her a problem.
My dream would be to have perfect vision .. but .. having known a few blind people i feel lucky i have my vision at all.
