deuteranopia /deu·ter·an·o·pia/ (-no´pe-ah) a type of dichromatic vision with confusion of greens and reds, and retention of the sensory mechanism for two hues only—blue and yellow.deuteranop´ic
deuteranopia [doo″ter-ah-no´pe-ah] defective color vision, with confusion of greens and reds, and retention of the sensory mechanism for only the hues of blue and yellow. adj., adj deuteranop´ic.
deuteranopia Type of dichromatism in which red and green are confused, although their relative spectral luminosities are practically the same as in normals. In the spectrum, the deuteranope only sees two primary colours, the long wavelength portion of the spectrum (yellow, orange or red) appears yellowish and the short wavelength portion (blue or violet) appears bluish. There is, in between, a neutral point which appears whitish or colourless, at about 498 nm. It occurs in slightly over 1% of the male population and only rarely in females. Syn. green blindness (although this term is incorrect as green lights appear to a deuteranope as bright as to a normal observer). See defective colour vision; dichro-matism.
deuteranopia Ophthalmology Red-green color blindness caused by a lack of middle wavelength–530 nm photopigment. See Color blindness. How to thank TFD for its existence? Tell a friend about us, add a link to this page, add the site to iGoogle, or visit webmaster's page for free fun content. |
