Sensorineural hearing loss is caused by damage to the cochlea in the inner ear or damage to the nerve pathways from the inner ear to the brain. Sensorineural hearing loss is the most common type of permanent hearing loss.
We donât really know why migraines cause light sensitivity, but itâs clear nearly everyone with migraine will tell you that they have sensitivity to light during an attack and many patients with migraine will tell you that certain kinds of light can trigger an attack (particularly those found in big box stores such as Target and Walmart).
Yet with or without flicker, individuals suffering from sensitivity to light experience issues. For example, people who suffer from migraines due to aura or perceptual disturbance. Aura migraines are migraines with symptoms prior to the actual migraine, such as dizziness, seeing zig-zag lines, and light sensitivity. Another issue that is exacerbated by fluorescent lighting is Irlen Syndrome, an optical processing disorder. Fluorescent lights are a major trigger for sufferers of this disease. According to Irlen.com, people with Irlen Syndrome have an increased sensitivity to light which causes headaches, restlessness and trouble staying focused when confronted with excessively bright lights.
