Welcome to NT!
You mise well have been describing ME! I've been told a few different things, but the one that I believe the most (in 'my' case) is regarding my anxiety/depression. Plus I try to wear too many hats between my job, twin boys graduating highschool this year, caring for my grandson....
My psychiatrist is pretty sure it is due to the depression.
You probably don't battle depression, so this of course wouldn't pertain in your case......maybe the 'wearing too many hats' might be tho?
I take meds and am fairly certain that this, in part, has to due with my short-term memory.
Other 'well meaning' people might try to say that it is due to aging, which could, I guess, to some extent in SOME people.
Certainly mention this to your doctor. If this is something that is bothering you, then it IS important!
Just some things I thought I'd throw out there
I hope you are doing ok with your eyes?
