I'm 62 and don't normally wear glasses, but reading glasses have become a big part of my life. I use 1.0 to look at my big screen, 1.75 to look at my phone and always misplace them somewhere.
Head to Costco and buy three three packs of the diopter strength you loose. It'll take a few years to loose 9 pairs and if you bust them out of the pack when a pair is lost then you always have a scratch free pair.
As "nerdy" as they look, the CliC brand readers (that separate magnetically at the nose, and that wrap around the back of your head with a solid band) are remarkably good at sticking with you as you move around in the day. 1.0's at the computer, 1.x around your neck.
Sadly, they don't make them with anything under 1.25.
