Legally blind criteria usually refer to visual acuity and visual field. A visual acuity of 20/200 or worse in the better eye with the best possible correction is one criteria, while a visual field of 20 degrees or less is another. While -5.00 is a measurement of refractive error (nearsightedness), it is not typically used to determine legal blindness.
