Some of my friends have bought contact lenses from this site:

They didn't go blind, but I wouldn't know how high quality the lenses are looking at the prices. NB, my friends don't need a prescription and they only used the lenses for a couple nights out.
I never bought coloured contacts becasue I have astigmatism, so the regular prescription lenses aren't good for me either.
My sister bough her coloured lenses at an optometrist becasue she needs them with a prescription...
Well, I hope the above link is helpful. ^^
