The Lang-Stereopad® is a new device for testing global near stereopsis. It is suitable for all age groups, including preverbal children (less than 1 year). This stereo test does not require the use of special glasses because of the combination of random dots with a lenticular screen, similarly to the the Lang-Stereotests® I-R and II.

The Lang-Stereotest® I-R is an easy-to-use screening-test designed for early detection of problems with stereoscopic vision of children. In contrast to most stereo tests it does not require glasses, due to the combination of random dots and a lenticular screen.
-
The Lang-Stereotest® II is used to test binocular spatial vision (stereopsis) in infants, children and adults.

The LEA Puzzle is designed for training and assessing typically developing toddlers and other young children. The puzzle also serves as an assessment tool for individuals with brain damage or for older children and adults with low cognitive abilities. The goal in the play training of toddlers and young children is to help them develop the concept of same/different as a prerequisite for early measurement of visual acuity.
