Problems solved by technology

Although this invention patent provides a cleaning method that uses electrophoresis to separate adhesions on contact lenses, the inventors have confirmed through a large number of experiments that the core of this electrophoretic cleaning technology is to provide a stable current in the cleaning agent, and at the same time separate the contact lenses. Adhesives (such as tear protein) are adsorbed on the electrode. In addition, the electrode needs to meet the use environment of repeated energization and cleaning solution immersion. Long-term use will not cause metal corrosion such as metal oxides, otherwise the impurities produced by metal corrosion On the contrary, it will pollute the contact lens and cause damage to the cornea. There is no technical solution to solve this technical problem in the prior art

Abstract

The invention relates to the field of cleaning of contact lenses, in particular to a nanoelectrode for cleaning contact lenses through electrophoresis. The nanoelectrode comprises a conductive base material, and platinum or platinum alloy of transition metal elements supported on the conductive base material. The nanoelectrode is stable in operating current, can absorb protein, and is difficult to corrode and long in service life.

Description

technical field [0001] The invention relates to the field of contact lens cleaning, in particular to a nanometer electrode used for electrophoretic cleaning of contact lenses. Background technique [0002] There are quite a few myopic people who choose to use contact lenses for the sake of beauty or convenience. However, long-term use of contact lenses will cause protein deposition, which will cause the lenses to lose their oxygen permeability, and will cause damage to the cornea after wearing them. Therefore, after wearing contact lenses for a certain period of time, they must be cleaned for reuse. [0003] At present, the most commonly used cleaning method for contact lenses is to put the lenses of the contact lenses into the two containers of the contact lens cleaning box, respectively inject cleaning potions, and then rub them with your fingers to remove the dust and protein deposits on the lenses of the contact lenses. , mucus, oil and other dirt to maintain the oxygen...
