[today’s run: none]
I recently heard a story on the radio about babies using iPods and such things. It had me thinking about our perception tools.
In college I learned about how to make perspective drawings. Those are drawings on flat paper that give the illusion of three dimensions. They use visual cues like converging parallel lines, scale of near vs. far objects, shading and shadowing.
But what they don’t do is require refocusing your eyes. So if you were given a life-sized perspective drawing you might notice that everything is in the same physical distance and your eyes don’t have to focus near and far.
I don’t know about you, but I don’t think I am very perceptive of when my eyes are focusing near and far except when I’m too close for my bi-focals.
So I was just wondering about those babies and their iPods. Not much exercise for the old eye-focuser muscles. Not that it is a new problem. Kids have been parking in front of the television since I was a pup. In my day the TV was across the room. Now they’ve got it at the end of their arm.
