hand held quick and efficient near test for heterophoria and cyclophoria - the patient rests the face-piece on his or her nose and looks through the two slits, the upper oblique wing divides the visual field into two halves so that the left eye sees the scale towards which the white arrow points and the right eye sees the arrow - the character and degree of the deviation can then be determined at once from the apparent position of the arrow on the scale - cyclophoria can be measured by adjusting the moveable wire forming the shaft of the red arrow until it appears to the patient to be parallel with the horizontal scale - the apparatus should be directed downwards
