Abstract
An ophthalmic device which comprises a holographic element comprising a medium comprising a phenylboronic acid group and, disposed therein, a hologram, wherein an optical characteristic of the element changes as a result of a variation of a physical property of the medium, and wherein the variation arises as a result of interaction between the medium and an analyte present in an ocular fluid.
Claims19
An ophthalmic device which comprises a holographic element comprising a medium comprising a phenylboronic acid group and, disposed therein, a reflection hologram,
- wherein an optical characteristic of the element changes as a result of a variation of a physical property of the medium,
- wherein the variation arises as a result of interaction between the medium and an analyte present in an ocular fluid, and
- wherein the reflection hologram is disposed in only a part of the ophthalmic device.
A method of detection of an analyte in an ocular fluid, which comprises:
- inserting in a user's eye a contact lens which comprises a holographic element comprising a medium comprising a phenylboronic acid group and, disposed therein, a reflection hologram,
- wherein an optical characteristic of the element changes as a result of a variation of a physical property of the medium,
- wherein the variation arises as a result of interaction between the medium and an analyte present in an ocular fluid, and
- wherein the hologram is disposed in only a part of the contact lens.
