Abstract
Abstract A protective shield for patients whose eyelids are unable to protect and moisten the eye. The shield comprises a transparent plastic bag filled with transparent fluid lying over the patient's eye and supported by the surrounding orbital structure. The shield is secured to the head by an overlying circular soft rubber mask allowing visibility and magnification of the eye. The mask in turn is attached to the patient by a strap with a Velcro-type closure.

Claim 1
Independent Claim
161 words
A protective eye shield comprising a sealed bag made of a thin, flexible, liquid impervious, transparent material and sized to fit over the eye of a patient and rest upon the surrounding orbital bone structure of the face to form a sealed chamber over the eye, said bag being filled with a liquid; and means contacting said bag in unattached relation therewith for holding said bag against the orbital bone structure of the face of a patient in fixed, noncontacting relation with the eyeball for protection of the eyeball by applying pressure to said bag against the orbital bone structure of the face, said holding means including an adjustable strap for surrounding the head of the patient and an opening for permitting viewing of the eye of the patient through said bag; said bag being maintained in fixed relation with respect to said holding means and the orbital bone structure only by the external pressure applied thereto by said holding means.
