When I was a kid we didn't have a computer. Home computers didn't exist until I was in my teens. We had one 12-inch black-and-white TV that received four channels when the rabbit ears were set up properly. I spent a lot of time outdoors. This is of course anecdotal, but I have needed glasses since before fifth grade. (I got my first pair of glasses in fifth grade, but in retrospect it was clear that I needed them much earlier. I can still vividly remember the first I ever tried on my new glasses and being astounded at the level of visual detail that existed in the world. Stars! Leaves on trees! Wow! I had no idea.)
