Fentesi
Fentesi is a term that refers to a specific type of visual distortion or illusion, often experienced as a brief, involuntary movement or shift in perception. It is not a recognized medical condition in itself but rather a descriptive term for a subjective experience. Individuals who report fentesi might describe seeing objects or their surroundings flicker, jump, or momentarily appear to move when they are actually still. This can occur in various contexts, sometimes related to visual fatigue, eye strain, or even as a transient phenomenon during periods of intense focus or stress.
The sensation of fentesi is typically short-lived and does not usually cause significant distress or impairment.
