“It’s typos, which I used to be good at catching, but, since my eyes have been going bad, I seem to miss them more often.”
My wife, like me is her eighties, about a year ago started having problems reading with her smart phones and kindles and newspaper.
Our health care organization fits reading glasses to use / in the above situations/uses in one set of glasses.
So we got her an RX adjustable reading glasses like I have.
Now, she reaches for her new reading glasses if she is having problems.
