Abstract

The invention relates to a preparing method of antibiosis antiultraviolet contact lenses. The preparing method of the antibiosis antiultraviolet contact lenses solves the problems of germ breeding on surfaces of eye balls, corneal edema, corneal neovascularization reaction and anaphylaxis and the like caused by the fact that protein, lipid and collagen and like in tears in adsorbed by the contact lenses are deposited at the surfaces of the lenses since the lenses and the eye balls are in long term contact during wearing in the prior art. The method comprises the steps: 1, preparing materials: preparing a material of zinc oxide nanoparticles, and a water gel material: 2, mixing the materials: uniformly stirring the zinc oxide nanoparticles and the water gel material; 3, ultraviolet irradiating: injecting the uniformly stirred zinc oxide nanoparticles and the water gel material into a rotating preparing die of the contact lenses and irradiating ultraviolet; 4, machining a shape; 5, separating the lenses from the die: placing the polished lenses into warm water. The preparing method is suitable for the field of manufacturing of the contact lenses.

Description

technical field [0001] The invention relates to a preparation method of a contact lens, in particular to a preparation method of an antibacterial and ultraviolet-proof contact lens. Background technique [0002] Due to the heavy learning tasks and the wide popularization of various screen display technologies, more and more people's eyes become myopia, which causes a lot of inconvenience to daily life. For the convenience of life, but also in order not to affect the appearance, more and more people choose to wear contact lenses. However, wearing contact lenses incorrectly and some incorrect habits will not only fail to make your eyes bright, but will damage people's eyes. Contact lenses can cause many harms to the eyes, and it has become a problem that people are more and more concerned about. Contact lenses, also called contact lenses, are lenses worn on the cornea of ​​the eye to correct vision or protect the eyes. Due to the direct contact between the lens and the eyeba...
