I have myopia, but I don't wear specs. I get foreign eye sensation in my both eyes and my eyes get red automatically sometimes and get normal back it's own. I also get itching but not normally. I am not sure but I think my foreign sensation gets bad when it contacts with water. I have some pigmentation of sclera below iris which looks like a downward paint stroke in light brown color. Could I ignore it, or could I wait before I show it to my doctor? I already had left it as it is from 6 years. What if left untreated? It doesn't bother a lot.
