I refused to get reading glasses when I started having trouble reading small labels some years ago. I blamed the problem on computers and that might have something to do with it but probably mostly age.

Instead I got this book: https://www.amazon.com/Better-Eyesight-People-Gillian-Snoxal...

It's not even a book. More like a pamphlet and could fit the whole thing in a

almost. But it worked in my case at least. A few weeks of doing the exercises and I could read find print labels again!
