Stereo Fly Test

This test has long been recognized as the standard stereopsis test.

Three tests in one: Fly Test for stereopsis, Circle Patters for depth perception, and Animal Series for younger children. Size: 6-1/2" x 8-1/2". Includes polarized goggle.

Graded Test measures stereopsis from 800 to 40 seconds at 16". New leather-like cover is much better than old plastic book.
