Purpose The LANG FIXATION CUBES, and LANG FIXATION STICK are orthoptic products for binocular diagnostics, to be used mainly by ophthalmologists, orthoptists, optometrists, and opticians. They were designed by J. Lang, inventor of the LANG-STEREOTEST®, to facilitate the orthoptic examination in children. They are being used for assessment of eye fixation, motility, accommodation, convergence, for cover test, and to prepare the patient for testing with the LANG-STEREOTEST® or the LANG-STEREOPAD®.
