  • Eye protection device
    Patent number: 5828437
    Abstract: A device placed by a support in front of the eyes of a user protects them against luminous aggression, in particular by a laser beam. The device includes a light attenuation system to attenuate the intensity of the received beam by a particular attenuation value. A light amplification system is disposed between the light attenuation system and the eyes of the user to amplify the intensity of the light received from the light attenuation system by a particular amplification value, but such that the intensity of the light transmitted towards the eyes does not exceed a prescribed maximal intensity that is not harmful for the eyes. The attenuation and amplification values are substantially equal.
