tritanopian.

/trʌɪtəˈnəʊpɪə/

Etymology: modern Latin, < German tritanopie (J. von Kries 1911, in Helmholtz's Handbuch der Physiol. Optik (ed. 3) II. 341), < trit- , variant trito- comb. form + an- prefix² + -opia comb. form.

Ophthalmology.

A form of dichromatic colour-blindness marked by reduced sensitivity and discrimination in the blue and green parts of the spectrum.

1915 J. H. Parsons Introd. Study Colour Vision ii. ii. 180 Cases of tritanopia or so-called blue-blindness are rare and mostly due to disease.

1937 Nature 10 July 49/1 A diagnosis can be made from the tables of dichromasy in general, and of protanopia, deuteranopia, and tritanopia in particular.

1978 Nature 23 Nov. 390/1 When the eye has been adapted to a bright yellow light, a marked loss of sensitivity to short-wavelength stimuli may be recorded immediately after the extinction of the adapting field. This phenomenon..was termed transient tritanopia by Mollon and Polden.
