Xanthopsia

Xanthopsia (or yellow-sighted) refers to the predominance of yellow in vision due to a yellowing of the optic media of the eye. In this condition everything seen has a yellowish tinge.

The most common cause is 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 Digitalis-derived digoxin, used to treat heart failure, induced xanthopsia responsible for the yellow tinting exhibited by many of Van Gogh's works. 

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.

The condition can be artificially induced by adapting the eye with blue light.
