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.\u003c\/p\u003e\n\u003cp\u003eThe book is printed using specialty transparent red and green inks, which provide exceptional cancellation when viewing the images using our Bernell Red\/Green Filters, which are included with the kit.

Targets present a range of binocular challenges from basic simultaneous perception to more sophisticated stereopsis, Varying target sizes, different fusion locks, and reference targets allow the examiner to probe and categorize binocular aspects of strabismic performance.

This technology also allows for color images to improve interest and images that will resist fading over time. It also has several challenges; the key one being apparent motion. If the test were set up like the traditional polarized version, the answer could have been obtained by even a monocular patient by moving the test from side to side to see which image moves; similar to the apparent motion seen in the polarized type tests by closing one eye at a time. In order to prevent such a hint, this test was designed differently. One image in each row appears to be closer and one appears farther compared to the circle in which they are housed. If the test is moved or twisted from side to side (which they are instructed not to do) one can tell which ones are different, but not whether they come out or go in.\u003c\/p\u003e\n\u003cp\u003eThe test has two test plates: \u003cbr\u003ePlate #1 features a Dinosaur character that tests gross stereopsis.\u003c\/p\u003e\n\u003cp\u003ePlate #2 features clip-art characters that are divided into two separate tests.
