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. The amount of WS12 releasably adhered to the polymeric lens body provides a basal tear concentration in lens wearers of 2 μg/ml to 8 μg/ml WS12 after 30 minutes of lens wear. The WS12-releasing contact lens can be used to increase contact lens comfort, reduce eye fatigue, reduce sensations of ocular dryness and impart a pleasant, cooling sensation in the lens wearer without causing stinging or burning upon insertion.

Abstract: A contact lens having an amount of at least one cooling agent and at least one TRPV1 inhibitor releasably adhered is described as well as method of manufacturing the same. The contact lens can be comfortably worn by contact lens wearers 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 and further can reduce or avoid any stinging/burning sensation when the contact lens is first used or a short time thereafter.
