DEFINITION

Classification: 351/215

Including light polarizing means:

(under subclass 205) Subject matter including a light polarizer wherein the light which is directed into or emerges from the eye of a patient is polarized to avoid reflexes and to obtain the greatest possible intensity of illumination and image-clarity.

(1) Note. The above light polarizers may comprise two adjustable light polarizing foils, or the foils may polarize the light linearly so that their planes of oscillation are at right angles to each other.
