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
We are actively testing people for their vision. Its relatively inexpensive and affordable for the masses.
Historically there was either no test or nothing to be done, or corrective lenses were expensive and extemely hard to acquire. You had to be very wealthy to even have the option of correction to consider. If its not even an option to consider, you just deal with it and probably don’t even really think about it much. Your eyesight was what it was.
