Our past anecdotal evidence prompted that a longer response window (RW) in the Trivector
test (Cambridge Colour Test) improved mature observers' estimates of chromatic …

The present study, an extension of Paramei [J. Opt. Soc. Am. A, 29, A290, 2012], provides
normative data on chromatic discrimination, using the Cambridge Colour Test, for normal …

Color discrimination was estimated using the Cambridge Colour Test (CCT) in 160 normal
trichromats of four life decades, 20–59 years of age. For each age cohort, medians and …

Color vision tests and multi‐test protocols in current use often fail to detect small changes in
red/green (RG) and yellow/blue (YB) color vision due to poor sensitivity. The tests also have …

This study evaluated reproducibility of the Trivector subtest of the Cambridge Colour Test.
Data for normal trichromats were obtained in Brazil (N=111 N= 111) at T0, six months (T1) …

The evaluation of colour vision and discrimination of an individual forms an integral part of
routine eye and vision examinations. Colour vision deficiencies have a high prevalence and …

Age-related changes in chromatic discrimination along dichromatic confusion lines were
measured with the Cambridge Colour Test (CCT). One hundred and sixty-two individuals …

Color vision tests use estimative of threshold color discrimination or number of correct
responses to evaluate performance in chromatic discrimination tasks. Both approaches have …

Purpose. We assessed chromatic sensitivity along the protan, the deutan, and the tritan line
(Cambridge Colour Test, CRS Ltd.), the loci of the unique hues (red, green, yellow, blue) …

Normal colour vision relies on the absorption of light by the short-, medium-, and long-
wavelength-sensitive cones. If one or more cone types are absent, or their function is …
