i also believe that because an myopic eye does not converge on a distance object, the person has trouble with his central vision, so he "tries to see" the whole snellen as once and uses his peripheral vision.

a negative refractive state LEADS to problems such as lose of saccadic movement, lack of central fixation, double vision, etc.

there's no evidence that these problems lead to a negative refractive state
