Counterpoint: If you are extremely nearsighted, contact lenses can give you much better vision than glasses. If I look at the red digits on an alarm clock from across the room while wearing glasses, and I tilt my head, I can see the numbers shift relative to the position of the alarm clock (think about light going through a prism and the colors separating). I had an old pair of glasses where the numbers would shift completely off of the clock and appear to be floating in the air, but my newer ones aren't that bad (I guess the lens material is better, or the lenses are just smaller so you can't look through them at such an extreme angle).
