Frisby Stereotest

Frisby Stereotest develops tests for assessing stereopsis: the ability to perceive depth using both eyes. The tests use real depth differences and require no special testing glasses, making them practical for examining children and adults.

The range includes the Frisby Near Stereotest for near vision, the compact Frisby Pocket Stereotest for screening, and the Frisby Davis Distance Stereotest (FD2) for distance stereopsis. The tests are used in orthoptics, optometry and ophthalmology, as well as scientific research.
