A vision condition where objects appear abnormally red or reddish in color, usually caused by eye inflammation, medication, or neurological issues.
From Greek erythro- (red) + -opia (vision condition). Medical term describing a visual perception disorder involving red coloration of the visual field.
Erythropia can be a symptom of serious eye conditions like acute glaucoma or certain medications, so when people report that 'everything looks red,' doctors take it seriously as a sign that something is wrong, not just a quirk of perception.
