Abstract: Light-transmitting contact lenses of Polymethylacrylate, Gas Permeable of Hydrogel materials may be immersed in an aqueous liquid medium contained in a storing and processing device, all of which are substantially transparent to the ultraviolet radiation spectrum. The lenses, liquid medium and storing device are all irradiated with ultraviolet radiation in a preselected frequency range, while simultaneously being subjected to ultrasonic frequency vibrations to thereby cause asepticization of lenses, liquid medium and storing device. The ultraviolet irradiation and ultrasonic vibrations are insufficient to cause detrimental molecular modification to the lenses or storing device, but does cause the formation of oxidation free radicals in the liquid medium. The unique combination of ultraviolet irradiation and ultrasonic vibration in the presence of the liquid medium containing oxidation free radicals cause rapid destruction of all microorganisms associated with the lenses, liquid medium and storing device.

Abstract: Ophthalmic dosages of chromophores in aqueous gel to block transmission of all or various spectrums of U.V. from the eyes, when used as ophthalmic liquid sunglasses.

Abstract: Method of using ophthalmic dosage of aqueous aloe vera gel as emollient and absorbent of UV radiation to shield eye retina by topically applying said gel in the eye.

Abstract: Method of establishing U.V. absorption spectrum equilibrium between the tear film and epithelium of the cornea by topically applying an aqueous dispersion of a high molecular weight polymer and an ocular chromophore as ophthalmic liquid sunglasses.

Abstract: A process for predictably recurving the cornea of an eye by disposing light-absorbing color bodies in the cornea, and then vaporizing at least some of the color bodies with light energy according to a predetermined pattern to form corneal-recurving scars. The light energy is focused in the cornea and defocused and diffused behind the cornea. The color bodies used are of a transient nature, and those not vaporized fade and disperse out of the cornea in due course.

Abstract: The cornea of an eye is recurved by disposing therein light-absorbing color bodies and thereafter vaporizing such color bodies according to a pre-selected design to form corneal-recurving scars.

Abstract: A light-transmitting contact lens body of polymeric material is immersed in an aqueous liquid medium which is substantially transparent to the ultraviolet spectrum. The lens body and the liquid are irradiated with ultraviolet radiation sufficient to asepticize them but insufficient to cause significant molecular modification of the polymeric material.
