You do need to see an Eye MD ophthalmologist immediately. Have your family doctor help you.
One thing you and others should know. The ER doctor may have washed his hands before coming in the room.
Some exam rooms do not have sinks and the MD washes at a central station before coming into the room then washes after he/she leaves.

You should call your doctor immediately. If you can't get hold of a doctor, I'd go to an urgent care facility immediately or even the ER if that's your only choice to get seen immediately.
I am not a medical professional, but if the fall caused some delayed bleeding inside your head somewhere, maybe this could be what's wrong? I am not saying it is, only that I would be very alarmed at vision loss or any other strange symptoms after a bump on the head.
Call your doctor right now!
