The device comprises a scleral contact lens (1) for locating and supporting the device on the eye and has an optical system with at least one discrete light source, e.g. an optical fibre (9) or a light emitting diode, and at least one discrete light receiver, e.g. an optical fibre (10) or a photodetector, mounted within a carrier (6) on the scleral contact lens (1). The device may be used for spectrophotometric analysis of the retina (31) enabling it to be used in a mide variety of diagnostic and monitoring techniques. In a further arrangement (Figs 3 and 6) the device may be used to provide infra- red pupillometry. Further sensing devices may also be provided on the contact lens (1).

Le dispositif comprend une lentille de contact scléral (1) pour placer et maintenir le dispositif sur l'oeil, ainsi qu'un système optique doté d'au moins une source lumineuse discrète, par exemple une fibre optique (9) ou une diode électroluminescente, et au moins un récepteur de lumière, par exemple une fibre optique (10) ou un photodétecteur, montés dans un support (6) sur ladite lentille de contact scléral (1). On peut utiliser le dispositif pour l'analyse spectrophotométrique de la rétine (31), ce qui permet son utilisation dans une grande diversité de techniques de diagnostic et de contrôle. Dans une autre réalisation (figs 5 et 6) on peut utiliser le dispositif pour la pupillométrie infrarouge. On prévoit d'autres dispositifs de détection disposés sur la lentille de contact (1).
