The Frisby Screener Pocket Stereotest is a portable, real-depth test for screening stereopsis, the ability to perceive depth using binocular vision. It uses physical depth and random-texture patterns, without requiring special viewing glasses.

Each test plate presents two random-texture patterns, with a hidden circular shape in one pattern. The patient identifies the pattern containing the hidden shape.

Choose between two pocket-sized versions. The 1-plate version includes one 6 mm stereopsis test plate and a pocket-sized case. The 2-plate version includes one 3 mm plate, one 6 mm stereopsis test plate, and a pocket-sized case.

The test is suitable for a wide age range, including preschool children, and is especially useful for shy preschool children.

Designed for use by optometrists, orthoptists, and vision screening teams in clinical practices, school screening, community programmes, and outreach settings.
