Growing up my dad told me to do a number of things, at times I thought he was nuts.
But in my dotage, I see the wisdom in what he said.
Unfortunately, what he needed to do was explain it better to his dim-witted son better first.
I forget when exactly he told me, I think I was maybe early High school. He stated that had no idea where the world or economy was going, but that I should seriously think about becoming an Optometrist.
Here is actually explained himself a bit. As a computer programmer (he wrote code for punch cards) yes, this was a long time ago. He also used a terminal to do his functions. His belief was that soon all would be staring at a screen all day and would wear out everyone’s eyes and that all would need to wear glasses.
I am the only one in my immediate family without a glasses prescription. At 45 I went to an optometrist, thinking I was going blind. Only to find out my vision was becoming normal…
At 60 I still see fine without glasses. Yet, I know my father was correct, staring at screens has made the number of people needing glasses increase. Other than outliers like myself.
