Claimants who are blind and unable to work may be able to receive disability benefits through the Social Security Disability Insurance or Supplemental Security Income programs. The Social Security Administration will determine a claimant is blind using the same criteria for each program. Claimants are considered "legally blind" if their vision can not be corrected in their better eye to better than 20/200. Legally blind can also include a limited visual field of 20 degrees or less in a claimant's better eye. Blind claimants may qualify for Social Security Disability Insurance if they have worked long enough and accumulated enough work credits. Blind claimants who have not worked may qualify for Supplemental Security Income if they meet the resource and income requirements of the SSI program. Claimants who have impaired vision but it does not meet the definition of "legally blind" according the Social Security Administration may still qualify for disability benefits if their impaired vision, combined with other health conditions, make it impossible for them to work.
