I remember being able to read the bottom row of an eye chart. My brother used to be able to read the tiny print at the bottom of the eye chart telling which company printed the chart, the copyright date, company address, etc.
Now my eyes cannot focus on anything inside of arm's length. That means I have to sit way back from my computer and use large font sizes. Mobile devices are special kind of hell for me. To use a smartphone I need to put on reading glasses, but when I'm wearing them I can't see anything more than about 5 feet away. Getting older has positives and negatives, eyesight is one of the negatives.
