ISHIHARA COLOUR TEST
These series of plates are designed to provide a test which
gives a quick and accurate assessment of colour vision
deficiency of congenital origin. This is the most common
form of colour vision disorders. Most
cases of congenital colour vision
deficiency are characterized by a
red-green deficiency which may be
of two types: a protan type which
may be absolute (protanapia)
or partial (protanomalia), and
a deutan type which may be
absolute (deuteranopia) or partial
(deuteranomalia).
• 31293 STEREOPTIC TEST
This test is performed at a distance of 30-40 cm and allows
evaluation of the cooperation between the two eyes to form
a single image to the brain from the two image provided
separately by each of the two eyes.
It can be used for children from the age of one year and adults
if you suspect strabismus, amblyopia or visual reduction of one
or both eyes.

• 31289 WORTH LIGHT TEST - with red/green glasses
The Worth 4 dot test, is a clinical test for suppression
of either the right or left eye. Suppression occurs
during binocular vision, when the brain does not
process the information received from either of the
eyes. This is a common adaptation to strabismus,
amblyopia, and aniseikonia.

• 31294 LANG STEREOTEST I

Stereotest I was created to
simplify stereopsis screening
