The right-handers(right-wingers) and the left-handed persons you know but do you know that the same
phenomenon also exists for eyes?
This small test is going to allow you to determine your main eye.
Use a paper drilled in the center, the tense arms centre an object to 2 eyes, then close successively the right(straight) eye then the left(awkward) eye
Opened left(awkward) eye: you see the object - you are a left-handed person of eye - goofy. (a minority as for hands ).
