Dont forget that it is a lot easier to have eye checkups nowadays and therefore theres a lot more diagnosis of these problems.

Myopia and presbyopia are mostly caused by the shape of the eyes, so that the lenses in your eyes cant project the image correctly on your retina = blurred vision. So blue lights as mentionned by some are not really the problem

I once read that the unnatural myopia epidemic in asias mostly urban regions is due to the severe lack of natural sunlight and lack of visual focusing on distant objects over the last generation.

I don’t have a full scientific background guy I’d imagine it has something to do with all the blue light a lot of people stare at for hours more per day due to screens on computers and mobile devices.
