Abstract

268,771. Zeiss, C., [Firm of]. April 1, 1926, [Convention date]. Sight-testing apparatus.-A holding device for apparatus used in eye-sight testing comprises a table a having two arms b, c pivoted about a vertical axis d. The arm b carries a support f for a binocular magnifier g and the arm c carries a support h for the illuminating device j. A chin rest m carried on a slide enables the pupil of either eye of the patient to be in the line of the axis A-A about which the arms b, c rotate. The testing-apparatus are thus always directed to the pupil of the eye and their angular disposition may be indicated on a scale a<1>, as shown.
