What you have to prove
Remaining vision in the better eye after best correction of 20/200 or less.
Medical evidence SSA expects
Ophthalmology exam records documenting best-corrected visual acuity using standard test charts (Snellen or equivalent), ideally from multiple visits to confirm stability.
Common misconceptions
The measurement is best-corrected — uncorrected vision doesn't count, even if glasses or contacts would push someone below 20/200. Progressive conditions being actively treated (e.g., responding cataract surgery) may not qualify until stable.
Didn't meet the listing? You can still qualify via a Medical-Vocational
Allowance — SSA's determination that your residual functional capacity, combined with
your age, education, and work history, leaves no jobs you can do. See our
appeals guide for what to do after an initial denial.
