So I've been lucky and had 20/20 vision my life while the rest of my family all wears glasses. I've never read about presbyopia or even heard of it.
I was noticing reading lately that I have to hold the book out about 5 inches (same with VR headsets) or else the text blurs, so I looked it up and apparently after about 40 pretty much everyone needs reading glasses and this is a thing? I'm turning 39 in October, so the timing is about right then.
I also read that if you get headaches it can be from looking at blurry text and I gotta say I've been having a decent amount of headaches lately from working at home staring at the computer screen all day. Hmmmm....
Since now isn't a good time to go see eye doctors, maybe just try to use one of those print tests to determine what kind of reading glasses I need and order a pair online.
But yeah, as someone with 20/20 vision, I didn't realize this was a thing where at some point your eyes just say "later, I'm out" and you need reading glasses. I'd been off books for about 6 months, so only started noticing it in the last week or two when I started a new book.
