This stereo tranaglyph™ test booklet was designed to offer a simple, yet effect 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.

The 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. The booklet also includes a printed answer key in the back of the book.
