2. Titmus Stereo Test
The Titmus stereo test consists of a combination
of contour targets. The most common targets are
a series of rings for older patients, animals for
children, and a large stereo fly that is used mainly
for screening. The circles test from 800 down to 40
seconds of arc while the animals test 400 to 100
seconds of arc. The fly has variable stereo from
the head to the thorax and contains disparity
values from about 700 to 400 seconds of arc

4. TNO Stereo Test
The TNO stereo test uses a random dot pattern.
Red and green glasses are required to dissociate
the patient. The test contains multiple plates with
hidden objects and can measure disparity values
down to 15 seconds of arc

6. Lang Stereo Test
The Lang stereo test is unique in that no
dissociating glasses are needed. This test is a
random dot test that can test disparity values
of 1200 arc seconds to 200 arc seconds

8. Frisby Stereo Test
Similar to the Lang test, the Frisby test does not
require the patient to wear dissociating glasses.
Instead, the test uses transparent plates with
different thicknesses to alter the disparity in the
test. The test can be performed at different
distances, which changes the disparity of the
test. The test can measure values between 600
and 20 arc seconds

10. Random Dot Stereo Tests
A number of stereo tests include the use of
random dot stereo targets that are viewed with
polaroid glasses. Some tests, such as the
Random Dot E, use single plates for testing,
while others may use shapes or animals
embedded in the test. The level of disparity
tested varies from test to test
