Abstract

20,572. Laurance, L., and Wood, H. O. Sept. 11. Optical systems.-In retinoscopy, a lens or system of lenses S is employed to magnify the observed pupil, the mirror M used being placed between this system S and the patient's eye P, and consisting of an unsilvered reflecting-surface. In some cases the last lens surface may be used as the reflecting- surface. The source L of light may be fixed or movable.
