Blind


Blindness in Social Security disability programs is "statutory blindness," which means:
  • You have a central visual acuity of 20/200 or less in your better eye, even while you are wearing a correcting contact lens or glasses in that eye; or
  • You have a limitation in the field of vision of your better eye, so that:
    • You have a contraction of peripheral visual fields to 10 degrees from the point of fixation, or
    • The widest diameter of your visual field subtends an angle no greater than 20 degrees, or
    • You have a contraction of peripheral visual fields to 20 percent or less visual field efficiency.

If you have a visual impairment that is not "blindness" as defined above, but your reduced vision (alone or in combination with other disabilities) prevents you from working, you may still be eligible for SSI benefits.
