30-Plus Researchers Link Striped Patterns and LEDs to Brain Overload in Vision Review

Summary
A review by more than 30 researchers argues that striped patterns, flickering LEDs, glare and crowded visual scenes can trigger headaches, nausea, eye strain and even seizures by overloading the visual cortex.
Brain-imaging studies cited in the paper suggest artificial high-contrast, repetitive patterns drive stronger neural responses and oxygen use than natural scenes, though the proposed metabolic-overload mechanism remains unproven.
At least 11 diagnoses and neurodivergent groups showed a similar discomfort profile, with autism, ADHD, dyslexia, migraine and epilepsy patients often affected more severely because inhibitory control of visual signals may be weaker.
LED flicker drew special concern: rapid dimming can create a 'phantom array' during eye movements, a problem linked to migraine distress, reading disruption and discomfort from some modern car headlights.
The authors say many fixes are cost-neutral if planned early—reducing contrast, avoiding striped interiors and testing designs with software—while noting the review synthesizes prior studies rather than reporting new experiments.
