Go to an optician, they will test you and make up a prescription and then order you in some lenses.
Lenses work the same as glasses, the difference being that you rest them on your eye and that (if you use monthly lenses) you have to rinse them after each usage with a special cleaning fluid.
The optician will explain this all to you if you ask.
I have very poor eyesight and i have contacts. can't reccomend them more0
