An ophthalmic device comprises a holographic element comprising a medium 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. The device may be used for the detection of analytes such as glucose.

L'invention concerne un dispositif ophtalmique qui comprend un élément holographique consistant en un support dans lequel un hologramme est disposé. Dans ce dispositif, une caractéristique optique de l'élément se modifie du fait de la variation d'une propriété physique du support, et cette variation est entraînée par l'interaction entre le support et un analyte présent dans le fluide oculaire. Ce dispositif peut être utilisé dans la détection d'analytes tels que le glucose.
