122 results about "Eyelid" patented technology

An eyelid is a thin fold of skin that covers and protects an eye. The levator palpebrae superioris muscle retracts the eyelid, exposing the cornea to the outside, giving vision. This can be either voluntarily or involuntarily. The human eyelid features a row of eyelashes along the eyelid margin, which serve to heighten the protection of the eye from dust and foreign debris, as well as from perspiration. "Palpebral" (and "blepharal") means relating to the eyelids. Its key function is to regularly spread the tears and other secretions on the eye surface to keep it moist, since the cornea must be continuously moist. They keep the eyes from drying out when asleep. Moreover, the blink reflex protects the eye from foreign bodies.

Eye lubricant

A mixture for enhancing eye lubrication comprises a plurality of microspheres having diameters ranging from about 5-40 microns combined with an aqueous component comprising water. The microspheres can be coated with oil. When the mixture is applied to the surface of a user's eyes, the microparticles will enhance lubrication during blinking and partially lift eyelids so that other components of the mixture can be better distributed beneath the eyelids. An oil can be added to the mixture. Preferably the oil is configured so that, when the mixture is agitated, it forms a temporary, thermodynamically unstable emulsion from which the oil quickly disassociates when the mixture is applied to the eye. The oil thus is quickly available to enhance lubrication performance.
