I was just looking out my window, and everytime I look through binoculars, there is a blind spot towards my nose, and usually I have to look with only one eye because something is blocking my other eye all together. a wobbly blackish grey blindspot thingy.
if I pull my face back and open my eyes really wide, it goes away. I made sure it wasn't my eyelashes or anything, what is it? it changes when I change the way the binculars are bent.

The binoculars may be adjusted wrong. They can be adjusted to make the eyepieces closer together or farther apart. It sounds like you have them too far apart.
