ABSTRACT:
An eyeshield for covering an eye that is being treated for some medical problem, so as to shield the eye until such time as it has healed. The eyeshield includes a substantially firm but bendable foraminous member having a concave interior surface that is adapted to be juxtaposed with the eye--to create a kind of shallow "vault" over the eye. The preferred material for the foraminous member is a sheet of 6061 aluminum alloy having a thickness of about 0.025 inch. The member has a peripheral edge or rim having the general shape of an ellipse, with a major axis of about 3 inches and a minor axis of about 2.4 inches. The eyeshield also includes a relatively thick but lightweight border that is permanently mounted around the rim in such a way as to completely envelop the same. The thick border is preferably formed from a flexible material that has rubber-like properties, so that it may yield to any manual bending of the foraminous member that may be accomplished in order to make the member achieve a better fit with the particular bone structure of a given patient. The foraminous member has a multitude of small apertures, preferably 100 or more, that are adapted to foster ventilation of the eye and the nearby facial skin. It also has a plurality of peripheral recesses, to aid in integrally molding the border to the foraminous member. Thus, the border and foraminous member may be permanently affixed to each other--and interlocked in such a way as to prevent any relative rotation therebetween.
