Full Description:
An easy-to-use screening and assessment test for stereopsis using natural vision, without the need for special glasses.
The Frisby Pocket is a one-plate screener assessment stereotest, compromising a 6mm 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.
How the Frisby Stereotest Works
The Frisby Stereotest is a free-space, real depth stereotest. The plate has two random texture patterns, with a hidden circular shape in one. The patient has to decide in which pattern the hidden shape lies.
Suitable for a wide age range, especially shy pre-school children and pre-verbal babies from 7 months.
