Method for manufacturing contact lens

Abstract

The present invention provides a method for manufacturing a contact lens, including providing a dry lens; subjecting the dry lens to a hydration process, and then obtaining a wet lens; and subjecting the wet lens to a sterilization process, and then obtaining a contact lens. Applying a first polymer to at least one of the hydration process and the sterilization process, applying a second polymer to at least one of the hydration process and the sterilization process, such that the contact lens includes a shell layer, and the shell layer includes the first polymer and the second polymer. The first polymer includes polyvinyl alcohol, and the second polymer includes polyvinylpyrrolidone.
