To be considered blind for federal disability programs in the United States, particularly through the Social Security Administration (SSA), your vision generally cannot be corrected to better than 20/200 in your better eye, or your visual field must be severely restricted.
The Definition of Legal Blindness for Disability Programs
The criteria used by the Social Security Administration (SSA) for determining disability based on visual impairment align with the common understanding of "legal blindness." These standards are crucial for individuals seeking benefits such as Social Security Disability Insurance (SSDI) or Supplemental Security Income (SSI).
Central Visual Acuity
According to the SSA, you are considered blind if your vision cannot be corrected to better than 20/200 in your better eye. This means that with your best corrective lenses (like glasses or contacts), you must be at 20 feet to see what a person with normal vision (20/20) can see at 200 feet. It's a significant impairment to your central, or straight-ahead, vision.
Visual Field Restriction
Beyond just central acuity, legal blindness also accounts for severe limitations in peripheral vision. Even if your central visual acuity is better than 20/200, you may still be considered legally blind if your visual field is 20 degrees or less in the better eye. This means your side vision is extremely limited, creating a "tunnel vision" effect where you can only see a small area directly in front of you.
Eligibility for Social Security Benefits
Meeting the SSA's definition of blindness can significantly impact eligibility for federal disability benefits. Individuals who meet these criteria are generally eligible for specific benefits designed to support those with severe visual impairments.

Key Visual Criteria for Disability Consideration
The evaluation of visual impairment for disability purposes often focuses on the following aspects:
- Central Visual Acuity: Is your best-corrected vision 20/200 or worse in your better eye?
- Visual Field: Is your visual field restricted to 20 degrees or less in your better eye?
- Irreversibility: The vision loss must be considered irreversible and not correctable with standard lenses.
These comprehensive criteria ensure that disability determinations accurately reflect the significant challenges faced by individuals with profound visual impairments.
