Zusammenfassung:A contact lens having antioxidant properties is described as well as methods of manufacturing the same. The contact lens can be present in a sealed contact lens package. The seal contact lens package can include at least a) a plastic base member having a cavity; b) a contact lens packaging solution in the cavity; c) a sterile, unworn contact lens immersed in the contact lens packaging solution in the cavity; and d) a cover that forms a liquid-tight seal with the plastic base member. As an example, the unworn contact lens is a silicone hydrogel contact lens having present therein vitamin E. The vitamin E is non-releasable from the unworn contact lens and the contact lens packaging solution has less than 1 ppm of vitamin E present. The vitamin E is trapped, embedded, absorbed, or non-covalently attached in the unworn contact lens.
