I have just been to an oculist 2 weeks ago and he checked the eyes and everything was okay but a few days ago I noticed that when I rub my eyes the right eye feels uncomfortable. The left eye doesn't. I can rub the left eye and it doesn't feel uncomfortable but the right eye feels strange. It feels as if the eyeball is inelastic or has too much pressure and because of this the rubbing is uncomfortable. My impression is also that the right eye protrudes a bit further than the other one. Is this possible that both eyes are not on the same level?

And what's also strange is that sometimes in the gym when my pulse is high then I see strange transparent patterns in front of my eyes which change with every heart beat it looks as if you're looking through a kaleidoscope.
