Randot Stereo Tests evaluate stereo depth perception by requiring patients to identify six geometric forms from random dot backgrounds (500 to 20 seconds of arc). This genuine Stereo Randot Test provides accuracy and reliability in testing stereopsis. Random dot patterns require the binocular individual to extract figures from a background in such immediate juxtaposition that any influence the distance between them might have on judgement is eliminated. The test figures can be identified only with polarized 3-D viewing glasses
