I have Astigmatism, so I have to wear specs. I don't like to wear them though, and more often than not, I'm not wearing any.
As far as contacts are concerned, I havn't ever worn them, mostly because my optician suggests that I don't need to buy contacts. If I want to, I can just stop wearing glasses. =P
What's weird is, the angle and power of the lens in one of my eyes changes pretty fast, so I have to get new glasses regularly (regularly = whenever I feel like going to the optician. :D)
