Glasses. If I had contact lenses, I'd need new ones every two weeks because I'd lose them, or I'd forget to put them in in the morning, which would be to difficult for me anyway, considering the way I usually feel in the morning. Besides, I can start cleaning my glasses if I feel nervous or have nothing to do.

> Although, I think if I could have laser eye surgery, I'd probably go for it... I'd love to be able to see when swimming and stuff, for one thing, and it'd be a lot easier to look in microscopes, and I wouldn't have to worry about losing my un-blurred sight. Sadly, my eyes are too messseeeed up for eye surgery as it is now. Oh well.

This is why I'm replying at this point of the thread. I've recently heard something (on a German TV magazine; I'm looking whether there are any links to websites in English) about a new development in that area, a method to measure the finer bumps and stuff more accurately. The device used is called an aberrometer. Controlling newly-developed lasers with its data has already been tested on a number of people; and many of them could see better than they had done with their glasses on, and 16 percent of the subjects had results of 200 percent or better. The problems with that are that there aren't many lasers of the necessary type yet, and of course it's not possibly yet to see how their eyes will develop over time, e.g. what aging will do to them.
For those of you who don't want a laser to cut away bits of your eyes, a Spanish Physics professor (called Pablo Artal) is, approximately, attempting to develop a new type of glasses based on the same principle (adaptive optics). The lab prototype is currently a bit too large for anyone's head, though: it's about the size of a table and weighs more than 100 kilograms. It's not been attempted to miniaturize it yet; but Artal apparently said he thinks the thing could be reduced to something approaching (electro-optical) glasses.
