Revision 09-4; Effective December 1, 2009
In determining blindness for aged, blind or disabled individuals, blindness is met if a person is considered “legally blind” as defined by the Social Security Administration. Based on a medical determination of blindness, a person is considered blind if the visual acuity in the person's better eye is 20/200 or less with corrective lenses, or if the person has tunnel vision that limits the field of vision to 20 degrees or less.
