Abstract

Here a pair of spectacles is introduced which, in screening the lateral incidence of light and in variably cross fading the risual point eliminates the contrast-diminishing intraocular proceeding stray light. It helps to achieve an improvement of the contrast by considering the x-ray photograph or television image. The result is that details are easier perceptible.
