108 views

No, 5.5 eyesight generally refers to a prescription strength of -5.50 diopters for nearsightedness. Legal blindness, however, is defined as having a visual acuity of 20/200 or worse in the better eye with corrective lenses or a visual field of 20 degrees or less. Therefore, having a -5.50 prescription does not equate to being legally blind.
