Why does everything fade black when i push my eyes inward?

Question

its really weird. use your index fingers to push from the outside of your eyeball inward. do it by pushing the skin where the corners of your eyelids meet. keep your eyes open and watch everything turn black. takes about 5 seconds

Answer 1

First, dont do that...

Second

When you push ur eyes back, i would assume ur hurting them

Third,

I think your not getting a clear site of what ur really seeing.  Light enter's your eye and bounce to the back, which your brain can process.  ur prob inverting the light elsewhere and not to the back of ur eye, where u "see"  thus causing you to see black

*i'm not 100% sure thats whats happening but it sounds reasonable

Answer 2

Answer 4
