My 20 yr old son wears contacts and he had an eye infection. He was away at college. Never said anything to me until after the fact. He never saw his eye doctor. He bathed the eye with warm water and the infection appeared to clear up. He told me recently that now when he gets tired the eye droops.He hasn't worn his contacts since he got the infection. He is perfectly healthy. Is there anything that can be done at this point or is this a permanent lingering effect ? Is it possible the infection never fully resolved? Thanks for any info.
