1. A contact lens, comprising:
- a substrate that forms at least part of a body of the contact lens, wherein the substrate comprises a hydrogel; and
a hydration component that is configured to generate information associated with a hydration level of an eye in which the contact lens is worn, wherein the hydration component comprises one or more sensors to generate the information associated with the hydration level, and wherein the one or more sensors include at least one sensor configured to sense swelling of the hydrogel.
