Tunnel Vision Apr 2026

Tunnel vision, or the loss of peripheral vision, is a condition where your visual field is restricted to a small central area, much like looking through a tube or binoculars. It typically occurs when the "rod" cells in the retina, which are responsible for side and night vision, stop functioning correctly.

Beyond biology, "tunnel vision" also describes a physiological response to extreme stress or intense focus:

Tunnel vision is often a symptom of serious underlying eye conditions:

: When the retina pulls away from the back of the eye, causing sudden vision loss.

: Inflammation of the optic nerve, often linked to conditions like multiple sclerosis. Common Symptoms:

: Frequently bumping into objects, tripping, or feeling anxious in crowded spaces. 2. Psychological and Situational Tunnel Vision

: Difficulty seeing objects or motion off to the side.
