Ok I get we all look at small letters and images on screens and paper these days. Is this why in the last 150 years or so millions and millions of humans need spectacles? Is it because we are meant to be looking at things from a distance rather than nearby so our eyes haven’t caught up?
In: Biology
I don’t have any scientific evidence lined up to back this, but I strongly suspect our modern society is the main cause of poor eyesight. Spending multiple hours per day focused on a screen or other object relatively close to your face (most likely) weakens your eyesight. Back in the day, people who spent all day reading or writing books needed glasses but the average population didn’t.
