I may now feel a slight irriation in one eye as i an aware of it again. I had them last year and have only in the last week noticed them again. so perhaps they went away for the winter. Sometimes i excidently sleep with the light on. I have done alot of travelling and outdoor activity in the past but i have suffered anxiety attacks in the last few months over other things things, not relating to my health. Can diet improve the whites of my eyes? Could I have high colestral? And no I am not on any medicines other from taking piriton occassionally.
