I've been using the same lenses for years. From the last one week or so, the moment i insert the lenses, my left eye turns very very red- as if I'm on some drugs. The rights eye does not have this problem and stays white.
The left eye loses the redness (becomes normal) within 10 minutes after lens insertion, and the redness does not re-appear for the rest of the day.
Is this dangerous? Do I need to see my optometrist for this?
