730005 The Laminated HRR (Hardy Rand and Rittler) Pseudoisochromatic Test, 4th Edition provides several very important features to provide the most advanced color vision test available: congenital and acquired testing, identification of the type of defect, and diagnosis of the extent of the defect as well as quick positive classification of normals. The HRR employs a sophisticated test strategy that virtually eliminates the potential for memorization and malingering. The figures used by the HRR Pseudoisochromatic Plates are independent of language and suitable for both adults and children. -
The Lang Fixation Cubes have been designed by J. Lang for the assessment of eye fixation, motility, accommodation, convergence, for cover test, and to prepare the child for testing with the Lang-Stereotest® or the Lang-Stereopad®.
5 child-friendly objects are presented on the side and the top of the cube. Some of them are also included in the two versions of the Lang-Stereotest® and of the Lang-Stereopad®, and on the Lang Fixation stick.
The Cube has a red handle.
Each turn of the cube shows a new object. The star on the top side and the other objects can also be used for the test of convergence.

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. -

This test can be used with infants, children and adults with low cognitive abilities when communication difficulties prohibit the use of optotype tests to measure visual acuity. This test measures an individual's ability to detect the presence of parallel lines of decreasing width to provide information about the function of some parts of visual pathways. Item #: GF1300 -
