Device for monitoring body functions

摘要: The device comprises a scleral contact lens (1) for locating and supporting the on eye has an optical system with at least one discrete light source, e.g. fibre (9) or emitting diode, receiver, (10) photodetector, mounted within carrier (6) (1). may be used spectrophotometric analysis of retina (31) enabling it to in wide variety diagnostic monitoring techniques. In further arrangement (Figs 5 6) provide infra-red pupillometry. Further sensing devices also provided
