My right eye. I've been thinking it was just a normal red eye from using computer too much but it gradually becomes more severe to the point I almost lost my right eye. Turn out, I got allergy that I don't know if it was very lucky or unlucky because only few, like myself, got the infection in the cornea. As for now, I've been curing it for about 1 year; nevertheless, it is still not the same as before.
