Abstract
A light-occlusive self adherent eye patch is disclosed comprising an absorbent pad having a nonadherent lower surface, a backing having a lower face adhered to the upper surface of the pad and extending outward from the periphery thereof, a light-occlusive pressure sensitive adhesive coating on the lower face of the backing to adhere the patch to the eye socket, and a removable liner protecting the lower surface of the pad and the adhesive prior to use. The pressure sensitive adhesive blocks at least 95 percent of the light of a preselected wavelength impinging on the adhesive.
