Un caso de eritropsia

Erythropsia or red vision (from the Greek erythros = red, and opsis = sight) is a temporary distortion of colour vision. This phenomenon is a chromatopsia or impaired vision. It consists of seeing all objects with a uniform reddish tint. This vision symptom usually alarms the patient. It is a little known process and is usually transient. It may be due to benign processes such as post-operative cataracts and drug toxicity or to be a consequence of more serious processes such as vitreous haemorrhage.
