In stock


The Lang Stereopad, similarly to the the Lang Stereotests I and II, combines Random Dots with a lenticular surface but offers more sophisticated assessments of stereopsis. Magnetic test cards are shown individually or in pairs on a handy red double-sided test panel. The test does not require specific glasses, and is highly sensitive for global stereopsis. It has no monocular clues and is ideal for preferential looking testing of infants and preverbal children.

In a pilot sample* of 240 orthotropic children between 1 and 10 years, all 33 aged less than 2 years could be tested with the the Lang Stereopad prototype, but none of them with the TNO-Test.
