Abstract
An apparatus for shielding a human eye of a patient while allowing the human eye contact with the air. A lens of the apparatus is fashioned to one or both of the eyes and is optically clear and optically correct in that it does not distort the patient's vision. The optically correct aspect of the lens is achieved by either polishing a mold for the lens or alternatively, by die-cutting the lens from an optically correct material. The lens may be held in place by an adjustable strap. A plurality of vents to allow the eye contact with the air are a plurality of apertures in the lens or a plurality of spaces or holes in a cushioning structure, where the cushioning structure is coupled to the perimeter of the surface of the lens facing the eye.
Claims18
An apparatus for shielding a patient's eye while allowing the patient's eye contact with air, the apparatus comprising:
- a. an eyeshield having an optically correct viewing area;
- and
- b. a plurality of vents surrounding the optically correct viewing area for allowing air to circulate through the eyeshield.
An apparatus for shielding a patient's eye while allowing the patient's eye contact with air, the apparatus comprising:
- a. an eyeshield having an optically correct viewing area;
- and
- b. a cushioning structure affixed to the perimeter of a first surface of the eyeshield wherein the cushioning structure includes a plurality of vents for allowing air to circulate behind the eyeshield.
A medical eyeshield for shielding a patient's eye while allowing the patient's eye contact with air, the medical eyeshield comprising:
- a. means for shielding a human eye said shielding means being optically correct;
- b. means for securing the shielding means;
- c. means for coupling the securing means with the shielding means;
- and
- d. means for circulating air between the human eye and the shielding means while preserving the optically correct nature of the shielding means.
A method of manufacturing an eyeshield comprising the steps of:
- a. producing a mold that will fashion an eyeshield wherein the eyeshield is optically clear;
- and
- b. polishing the surface of the mold to facilitate the eyeshield being optically correct.
A method of manufacturing an eyeshield comprising the steps of:
- a. cutting an eyeshield from an optically clear and optically correct material;
- b. affixing a cushioning structure having a plurality of vents to the perimeter of one surface of the eyeshield;
- and
- c. coupling an adjustable strap with the eyeshield.
