摘要：

A lens assembly generally includes an ophthalmic contact lens, a rotating collar configured for rotation around at least a portion of an outer surface of the lens, and an indexing assembly configured to provide tactile feedback to a user in the form of increased resistance to relative rotation of the lens and the collar at uniformly spaced indexing positions.
