erythropsia
Very LowTechnical/Medical
Definition
Meaning
A visual condition where objects appear to be tinted red.
A type of chromatopsia (abnormal color vision) specifically characterized by the perception of a red tinge or hue on normally colored objects. It is a symptom, not a disease itself, often associated with certain drugs, eye conditions, or after cataract surgery.
Linguistics
Semantic Notes
The term is purely clinical/medical. It denotes a pathological or drug-induced symptom, not a normal state of vision. It is distinct from 'erythrophobia' (fear of blushing).

FAQ
Frequently Asked Questions
No, it is a symptom or condition that can be caused by various underlying factors like medication, eye surgery, or disease.
Common causes include certain medications (e.g., digoxin), ocular conditions affecting the retina or lens, and sometimes as a temporary effect after cataract surgery.
Color blindness (daltonism) is usually a congenital deficiency in distinguishing certain colors. Erythropsia is an acquired anomaly where all objects appear tinted red, often due to a pathological or pharmacological cause.
Treatment involves addressing the underlying cause, such as adjusting or discontinuing a causative medication or treating the associated eye condition.
