Please tell me, could you tell me why we don't have a blind spot when both eyes are open?

Brain compensation: The brain is the actual site of vision and it compensates for permanent things in the vision. Both of your eyes have a blind spot, a spot with no light receptors where the nerve exits, which can be mapped out by your ophthalmologist in a test called visual field. Your brain has learned to ignore these holes in the vision and fills them in so you are not aware of them being present.
