The other night we'll watching tv I suddenly  got horrible blurry vision.  It felt like something was in both my eyeballs at the bottom of my eyes.  I went to look in the mirror and saw in each eye (on my eyeball) just above my lower eyelid was a clear piece of skin.  One on each eye.  It was shocking to see.  I basically lost half my vision and couldn't see.  After about a hour, it went away and my eyes returned to normal.  Now I'm just left with very dry and painful eyes. I looked everywhere but couldn't find anything about this.  Can anyone help and tell me what this was.
