You can get a look at a whole lot of different contacts at your local optometrist's office. Most offices do have some "wild" versions to sample. I recommend going to yours and they can tell you what the best kinds for your eyes are and they will show you how to use them and take care of them.
Also, I know there there are a bunch of threads concerning contact uses and good links where to get them. And I can't stress enough about going to your optometrist before you start using contacts.
