To be fair, most people wearing glasses are exactly due to not being exposed to enough (natural!) sunlight when they are young.

It's the same thing with bracers and propensity to tooth decay. There are minor genetic factors involved but it's mostly due to the modern industrial lifestyle.

I would say the main reason of the increase of people wearing glasses over the decades is that good eyesight for reading is much much more important than 50 or 100 or 150 or 200 years ago.

People that couldn't read or didn't have to read in their job rarely got tested or their bad eyesight was ignored.

Oh, I'm talking about myopia. Presbyopia is almost inevitable with age regardless. Now, astigmatism has unclear causes, but most of it is likely not genetic, so there you go again.

I don't think most people realize how physiologically messed up we are compared to our ancestors (not folks from the Middle Ages, I mean, but true Homo sapiens hunter gatherers). It's like comparing wolves to pugs.
