Abstract: A WS12-releasing contact lens is described as well as method of manufacturing the same. The WS12-releasing contact lens comprises a polymeric lens body and WS12 releasably adhered to the polymeric lens body, and releases from 0.05 μg to 0.5 μg WS12 after 1 hour in a release media or when worn by a human subject. The WS12-releasing contact lens can be comfortably worn by a symptomatic contact lens wearer and can increase the duration of comfortable lens wearing time and/or reduce lens awareness events and/or reduce contact lens dryness in a symptomatic contact lens wearer.
