Bilateral Visual Acuity Impairment (DC 6066) is rated by the U.S. Department of Veterans Affairs under DC 6066 of 38 CFR § 4.76, § 4.79, DC 6066 across 10 severity tiers (90% / 80% / 70% / 60% / 50%…). Service connection requires (1) a current diagnosis, (2) an in-service event, injury, or exposure, and (3) a medical nexus opinion linking the two under 38 C.F.R. § 3.303.
Reduced visual acuity in BOTH eyes where neither eye is anatomically lost, light-perception only, or at 5/200 (those higher-severity findings rate under DC 6063, DC 6064, or DC 6065 respectively). DC 6066 covers the seven sub-tables for vision-in-one-eye 10/200, 15/200, 20/200, 20/100, 20/70, 20/50, and 20/40 — each paired with fellow-eye Snellen acuity to yield a rating from 0% to 90% across 28 pairings. Common clinical drivers: bilateral diabetic retinopathy, bilateral macular degeneration (AMD), bilateral cataracts (postoperative residuals), retinitis pigmentosa, optic neuropathy.
