I use contacts, the biocompatibles ones. They are pretty good contacts, but I have a little bit of astigmatism, and can't see as clear through contacts as i would glasses. I could get the astigmatism ones, but they are a buttload more expensive, and are specific to each eye, and take a bit longer to put in. My prescription is at -3.50 for both eyes. I am nearsighted.
Hopefully, I am going to get laser surgery on my eyes when I'm about 23 or sooner. It's getting cheaper now, and the technology and surgeons have gained a lot of experience.
Those contacts that you can leave on for a month straight scare me. How do they let enough oxygen into your eye? And I'm sure you still have to put in special drops in once a day at least. Anyone have experience with these?
