Mesh section dissappearing in Object mode. Help?

I’ve been working on creating a character model, and when making the eyes, i created meshes while in edit mode for the eyes. When I go back to object mode, however, the eyes dissapear, everything else is there, and when i return to edit mode, everything is there, so i’m pretty confused. Any ideas?
