1. An ophthalmic lens for detecting glucose in an ocular fluid, comprising:

  • competitor moieties;

    glucose oxidase molecules comprising glucose/competitor moiety binding sites to which glucose and competitor moieties can reversibly bind; and

    detectable labels which are associated with the glucose oxidase molecules and/or the competitor moieties and which are capable of generating an optical signal that changes in a concentration-dependent manner when glucose reversibly binds to the glucose/competitor moiety binding sites.
