<p>A device for measuring in vivo the opacity of the lens of the eye, in particular in cataracta nuclearis, comprises a light source (16) which irradiates the eye lens with at least one angular monochromatic light beam of short wavelength. The intensity distribution of the corresponding fluorescence spectrum is picked up in the long-wave range by a receiver (26). The wavelength corresponding to the maximum of the fluorescence spectrum is represented according to the degree of opacity of the eye lens by a signal processing circuit (29) and a display apparatus.</p> |
