Eyes hurt, kinda discolored?!

people are telling me when i look to the side.. so you can see the side or back of my eyes.. people are saying their yellow, and then grey, then white at the front. they kinda hurt too, like when i look around sometimes... also i don't feel so great.
kinda feel sick to my stomach... and tired..
I'm wondering, anyone have any ideas what could be wrong with me?
