Contact lens products

Abstract

A contact lens product comprises a contact lens packaging preservation solution, a silicone gel contact lens immersed in the contact lens packaging preservation solution, and a sealed packaging container for containing both. The contact lens packaging preservation solution comprises sodium chloride, sodium dihydrogen phosphate, disodium hydrogen phosphate, a hydrophilic polymer, and water. The concentration of the hydrophilic polymer in the contact lens packaging preservation solution is 0.1~2.0% w / v. The hydrophilic polymer is selected from at least one of polyethylene glycol, polyvinylpyrrolidone, and poloxamer 407, and the number average molecular weight of polyethylene glycol is 4000~12000 g / mol. This invention provides a silicone gel contact lens product that, when worn, does not easily accumulate lipids on its surface and possesses both moisturizing and lubricating properties, thus providing a comfortable wearing experience.
