NoIRs and low vision.

Records of three hundred and eighteen low vision patients from three low vision centers were reviewed to determine patient preferences for NoIR light filters based on ocular disease and visual acuity. Eighty-nine percent chose the #101 and #102 filters. Patients with dry macular degeneration, chronic open angle glaucoma, and retinitis pigmentosa showed a greater preference for the #101 NoIRs. When visual acuity dropped below 20/400, no patients selected the darker filters (#108 & #109).
