  • Publication number: 20220023659
    Abstract: A computer implemented method for controlling a device adapted for projecting a light beam on at least a part of an eye of a wearer, the device having an optical module comprising a light source, a pupil being defined for the part of the eye, the method comprising a step of providing the size of the pupil, determining a command law of the radiant power of the light source, the command law being determined on the provided pupil size, and sending the determined command law to the light source, wherein a maximum light intensity and a minimum light intensity are defined for the part of the eye and, at the step of determining, the command law further depends from at least one parameter selected in the group of the maximum light intensity and a minimum light intensity, each one of the maximum light intensity and the minimum light intensity varying spatially in the part of the eye.

  • Patent number: 11135446
    Abstract: The present invention concerns a medical device (10) intended to be worn by a human wearer, the medical device (10) defining a first area (26) and a second area (28), each area being intended to be positioned in front of a respective eye of the wearer. The medical device (10) comprises a frame (10), comprising a rear shell (34). The rear shell (34) defines a hole (54) facing the first area (26) and the rear shell (34) is opaque facing the second area (28). The medical device (10) also comprises an optical module (20) in the first area (26). The optical module (20) comprises a light source (70) and an optical system (72). The optical module (20) is arranged to send a light beam through the hole (54). The medical device (10) further comprises an electronic circuitry (18), adapted to command the optical module (20).
