What this listing is about
A composite metric can qualify a claimant even when neither acuity nor field loss alone is quite severe enough. SSA allows meeting the listing by visual efficiency % or by a visual impairment value that sums acuity and field components. eCFR
Exact text (SSA)
“2.04 Loss of visual efficiency, or visual impairment, in the better eye:
A. A visual efficiency percentage of 20 or less after best correction (see 2.00A7d). OR
B. A visual impairment value of 1.00 or greater after best correction (see 2.00A8d).” eCFR
Checklist
- Better eye, after best correction.
- Show either:
- Visual efficiency ≤ 20%, or
- Visual impairment value ≥ 1.00 (acuity impairment value + field impairment value). Social Security
Proof tips & testing
- Include visual acuity and automated perimetry MD to compute the visual impairment value (SSA method divides |MD| by 22 and adds to acuity impairment value).
- Provide tables/worksheets showing math from the official formulas; attach the perimetry printouts.
- Confirm device standards and testing conditions per 2.00A9. Social Security
Definitions: Visual efficiency % = product of central acuity and field efficiency; visual impairment value = acuity impairment value + field impairment value per SSA formula.
