Another thing about contacts and glasses (that's true for at least me, and many other people I know) is that you have to keep constantly updating prescriptions, about every other year or so. But I have heard people say that if you don't wear corrective lenses that often then it's not necessary, because you're not making your eyesight worse. Assuming that this is true, dependence on technology makes us depend on technology even more. Though I'm pretty sure that's a myth, it's kind of a scary thought. And easy to believe, about as easy as pop psychology like "humans only use 10% of their brains."

I don't know if I could survive very long without corrective lenses. Without them, I can't read what I am currently typing, and I'm horrible at facial recognition. I wouldn't be able to do very well in class or at work without them. I remember the first time I got glasses and suddenly I was able to understand how people could read the chalkboard from so far away, and that I could see individual hairs on the back of people heads as opposed to a matte blur. I don't think I would be able to survive without my glasses--for one thing, I wouldn't be legally allowed to drive. While I might not need to do that now a lot, it is something that I anticipate needing in the future. More relevant: slipping on black ice. Ouch.
