Abstract: Objective To compare college students wearing the influence of different light transmittance glasses for stereo vision to provide a scientific reference for college students to choose colored glasses. Methods 50 normal binocular vision(5.0 or higher), three-dimensional visual sharpness(60 s or less)of normal students of of the first and second grade volunteered for the experiment of Hebei University were adopted Yanshaoming's check figure in stereo vision inspection method, conducted different light transmittance of the glasses, stereo vision test. Results The tinted glasses of our high light transmittance of stereo vision was better than that of low light transmittance of the lens. Conclusion Different light transmittance blinkers have different effects on college students of stereo vision.
