LANG's STEREOTEST® represents the current standard of stereotests based on random dots, without the need for 3D glasses and with high sensitivity and specificity for stereopsis.
The test combines random dots and a lens grating and is designed for rapid screeening of binocular vision in all age groups, including very young children.
The card is presented at a reading distance and the patient is asked what he/she sees, while eye movements are observed.
Figure recognition is only possible for subjects with full stereopsis, while patients with amblyopia and strabismus (even at a reduced angle) fail the test.

The STEREOTEST® II DI LANG has four stereograms with disparities of 600, 400, 200 and 200 arcsec, of which only one is also visible monocularly.

Made in Switzerland.
