Individually packaged boards.

Test created with the aim of simplifying the detection of stereopsis in children.

This test is suitable for vision screening in schools and for assessing the visual needs of children with special needs from the age of 5. Hole for hanging the board on the wall. Dimensions: 45.7 x 50.8 cm; folded: 45.7 x 25.4 cm.

LANG II TEST

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 they see, 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.

Two wooden characters (white and red) to capture the attention (both visual and auditory) of pre-verbal children. Can also be used for convergence tests. Shaking the pencil produces a sound.
