Keratoconus - a lovely little genetic present from my father. It's a condition where the cornea thins and loses its rigidity, causing it to bulge or slip. Hence, the contacts effectively hold it in the correct position. Glasses would work in the short term for the vision, but wouldn't help stabilise the condition in the way the contacts do. I guess the nature of the condition is that the cornea is constantly changing shape, and thus the contact lenses don't fit as well after a while, allowing bits underneath them and driving me insane in the process!
