How can I get insurance while in school?

I live in Maine and I'm no longer covered on my parents insurance (I'm 22) and I need coverage mainly for vision. I legally need corrective lenses to drive and just see 15 feet in front of me. I go to school full time and work about 30 hours a week. I can't find any good info on insurance, specifically vision, for someone like me. I rarely have to go to the hospital for anything so my main reason for insurance would be vision. However, dental would be nice too.
