A test for colour blindness in which the patient matches coloured skeins of yarn.

Description

A test for colour blindness in which the patient matches coloured skeins of yarn. The test is based on the Young-Helmholtz theory of colour perception which states that there are three sets of colour perceiving elements in the retina. According to the theory, a defect in one of these elements causes a variant of colour-blindness.

See also Young-Helmholtz three colour theory, under Thomas Young, English physician and physicist, 1773-1929.

Wilson was the first in Britain publicly to point out the potential hazards of colour-blindness in railwaymen and seamen.
