At 56 I've learned to pay attention to little hints your body gives you. I'm NOT at all neurotic and only see my Doc - if I have to. But I've learned in my life thru family, etc., you DO get clues before a disaster.
I have worn glasses since 3rd grade. Contacts over the last 10yrs or so on occasion. No glycoma. Not smoking now (smoked for16yrs, quit for 16, smoked for about 5 & quit over a year ago).
So... when I rub my eyes lately I can HEAR the lids let go from my eyeballs. Like they are loose or my eyeballs are shrinking and the suction is lessening. I attribute most stuff to aging... Is this an aging thing?
