- Also known as violet vision and purple vision. The term ianothinopsia comes from the Greek words ianthinos (violet) and opsis (seeing). It is used to denote a *chromatopsia (i.e. a temporary aberration of colour vision) in which whites are seen as purplish or violet. Ianothinopsia tends to be classified as an *entoptic phenomenon. The term is used in opposition to the terms *cyanopsia (blue vision), *chloropsia (green vision), *erythropsia (red vision), and *xanthopsia (yellow vision).ReferencesPinckers, A., Cruysberg, J.R.M., Liem, T.A.
