I was having trouble with my contact(s) this morning.
I finally decided to just take it out.
I found the problem.
I wear a contact in just one eye, it works very well, usually.
I wear the disposable kind.
I had two or three contacts in, two for sure, bur it feels like there's another one in there somewhere.
Lucky I figured it out or
Pretty soon I'd be seeing the computer screen with one eye and Beijing with the other.
