The Frisby Pocket Stereotest is a new addition to the Frisby Stereotest range.  It comprises one 6mm plate and one 3mm plate in a pocket-sized case, convenient and easily transportable.

It is ideal for stereopsis screening, in optometrist practices, doctors surgeries or in school screening programmes.  It is very easy to use and can be administered by non-professionals.

The plates have two quadrants, and are presented to the subject using the white background of the case (but should not be presented flat against the case, see diagrams).  The purpose of the test is to demonstrate stereopsis by the subject detecting in which quadrant the target is hidden.

It tests for stereopsis even if reduced vision or amblyopia is present because of the coarse elements included the texture – this is a valuable feature of Frisby Stereotests.
