Lang Stereopad
The Lang Stereopad, similarly to the Lang Stereotests I and Lang Stereotest II-R, 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.

LANG STEREOTEST II R
Intended use and main features
Lang-Stereotests are orthoptic products for binocular diagnostics and screening of disorders of stereoscopic vision in adults and children, for medical professionals. The Lang-Stereotest is used for rapid screening of stereopsis vision in all age groups from 6 months of age. Since loss of stereopsis is considered a key symptom of amblyopia (lazy eye), failure to recognise random dot stereograms may indicate a previously undetected, treatable disorder of binocularity (e.g., microstrabismus, anisometropia). Lang-Stereotest have proven to be highly specific and highly sensitive for stereo vision. Thanks to the unique combination of random dots and a lenticular lens, no special glasses are needed, and the eye movements of the subject may be easily observed.The test exists in the versions Lang-Stereotest I and II, and the revised versions I-R and II-R.

Bernell Stereo Test Book Near and Far Tests
Pediatric Opthalmology, Stereo Acuity Test, Stereo Acuity Testing, Stereo testsBernell Stereo Test Book Near and Far Tests
Test books now have improved features, including tabbed title test pages, better test plate flow and thicker more durable pages.
This stereo tranaglyph™ test booklet was designed to offer a simple, yet effective option for screening stereoscopic vision deficits in patients of all ages. This economical screening solution helps to detect binocular vision issues such as poor stereopsis, amblyopia, suppression and strabismus. The test booklet combines three standard variations of stereo screening books into one convenient package! This includes: near stereo acuity for both gross stereopsis and fine depth perception, distance stereo acuity for gross stereopsis, and random dot gross stereopsis and fine depth perception. As an added bonus, the cover is comprised of stereo images of shapes and figures positioned at various distances, which can be used as a quick binocular screening tool.

Frisby Near Stereotest 3 plates
First launched in 1983, it is used in orthoptic and ophthalmic clinics and by optometrists world-wide.
- Tests for stereopsis using natural vision, with no special glasses. It has three transparent plates, which are presented to the patient one at a time against the clear background provided by the fold-down flap of the storage box.
- Tests for stereopsis, even if reduced vision or amblyopia is present because of the coarse texture elements included in the pattern.

LANG STEREOTEST II
The Lang-Stereotest® II is an easy-to-use examination instrument designed for screening, i.e. early detection of spatial vision problems in children.
The Lang-Stereotest® II is a supplement to the proven Lang-Stereotest® I (Star, Cat, Car) and is also used to test binocular vision according to the same principle. In addition to three figures that are only visible binocularly (crescent moon, car and elephant), there is also a contoured star that can be seen with one eye. The individual figures appear to be set off from the background at different distances.
Many users had requested another stereoscopic examination card as an alternative to the Lang stereo test® I. In version II, the random dots are smaller and less dense. The disparities are chosen a little finer, namely 200 arc seconds for the moon, 400″ for the car and 600″ for the elephant at an observation distance of 40 cm. The star, which is also visible monocularly and has a disparity of 200″, is intended to improve diagnostics in young children by increasing attention and reaction. In addition, subjects without binocular vision remain less disappointed.
Note: the LANG-STEREOTEST does not measure visual acuity and does not substitute for an ophthalmologic examination. A negative test result indicates only a lack of stereoscopic vision at the time of examination.

LANG STEREOTEST I
The Lang-Stereotest is an easy-to-use examination instrument designed for screening, i.e. early detection, of spatial vision problems in children. The test is designed for rapid screening of stereo vision in all age groups from 6 months of age and includes a star, a cat and an ordinary car that appear to be raised from the background at different distances.
The Lang-Stereotest I is an orthoptic product for binocular diagnostics and screening of stereo vision disorders, for medical professionals. Since loss of stereopsis is considered a key symptom of amblyopia (weak eye), failure to detect random dot stereograms may indicate a previously undetected, treatable disorder of binocularity (e.g. microstrabismus, anisometropia).
The Lang -Sereotest has been shown to be highly specific and highly sensitive to stereo vision. Thanks to a unique combination of random dots and lenticular, special glasses are unnecessary, and gaze behaviour remains observable.
Important: The Lang-Stereotest neither measures visual acuity nor replaces an ophthalmological examination. A negative test result, i.e. failure to recognize the figures, merely indicates impaired stereo vision at the time of the examination.
