......that a work colleague and I have been mulling over. If your eyeballs came out of their sockets but were still attached to the optic nerve would you still be able to see?
yes.
but if they are not in the socket properly, with all the ciliary muscles & ligaments attached, then the eye wouldn't b able to control either the focus or the amount of light entering the eye.
so your brain would still receive the information through the optic nerve about whatever the eye was "looking" at (whilst it dangled about your navel!!) but it wouldn't be a very good picture!
not a doctor, but very recently taught "eyes & vision" at school, including dissection of sheeps eyes... fascinating stuff.
And the above question comes up quite alot!
