'''Xanthopsia''' is a color vision deficiency in which there is a dominantly yellow bias in vision. The most common causes are digoxin's inhibitory action on the sodium pump, and the development of cataracts which can cause a yellow filtering effect.
It has been suggested that Van Gogh contracted xanthopsia as a result of digoxin consumption. Digoxin is a medication derived from digitalis and used to treat various heart conditions. This theory claims xanthopsia as the cause of the yellow tinting exhibited by many of his works.<ref>{{cite web |url=https://psyc.ucalgary.ca/PACE/VA-Lab/AVDE-Website/vangogh.html |title=Van Gogh, Vincent (1853–1890) |department=Art, Vision, & the Disordered Eye |website=Vision & Aging Lab |publisher=University of Calgary |access-date=2015-07-09 |archive-date=2005-02-23 |archive-url=https://web.archive.org/web/20050223113607/http://psyc.ucalgary.ca/PACE/VA-Lab/AVDE-Website/VanGogh.html |url-status=dead }}</ref>
Xanthopsia is also a rare side-effect of jaundice, in which bilirubin may be deposited into the eye in sufficient quantity to produce a yellow tint to the vision.<ref>{{cite book |last=Weatherall |first=D.
