Pattern glare

Pattern Glare

Pattern Glare (/ˈpætərn ɡlɛər/) is a condition where individuals experience discomfort or visual disturbances when viewing certain spatial frequency patterns, particularly high-contrast striped patterns.

Etymology

The term "Pattern Glare" is derived from the English words "pattern", meaning a repeated decorative design, and "glare", meaning a bright, dazzling light. It was first used in the context of visual perception to describe the discomfort experienced by some individuals when viewing certain patterns.

Symptoms

Symptoms of Pattern Glare can include headache, eye strain, nausea, and dizziness. These symptoms can be exacerbated when viewing striped patterns, such as those found on a zebra or barcode.

Causes

Pattern Glare is thought to be caused by an overactive response in the visual cortex of the brain to certain spatial frequency patterns. This overactivity can lead to the symptoms associated with Pattern Glare.

Treatment

Treatment for Pattern Glare typically involves avoiding the patterns that cause discomfort. In some cases, color therapy or the use of colored overlays can help to reduce the symptoms of Pattern Glare.
