Tension-type headache can also cause photophobia during and between headaches. Fluorescent light contains invisible pulsing, which is likely why so many report it as a migraine trigger. Light and other visual stimuli also can trigger migraine attacks: for example, flickering or pulsing lights, repetitive patterns, glare, bright lights, computer screens, TV, and movies. Between attacks, many people with migraine are more sensitive to light than those without migraine. Between 80% and 90% of people living with migraine and headache disorders will experience photophobia during migraine attacks and even can find low levels of light to be glaring or painful. Photophobia is so common in migraine that it is one of the symptoms that health care practitioners rely on when making a diagnosis. Which Headache Disorders Are Associated with Photophobia? The cells are more sensitive to some wavelengths of light than others, with particular sensitivity to blue-green light. These cells are distinct from the rods and cones in the eye that enable us to see. Researchers also found a special kind of cell in the eye-intrinsically photosensitive retinal ganglion cells. Light can worsen pain during an attack by activating nerve cells in these areas of the brain. A team led by researchers at Harvard Medical School published a study in 2010 that found a pathway from the eyes to areas of the brain that are active during a migraine attack. Photophobia has been recorded in medical writings since the 1930s but has not been well understood scientifically until recent breakthrough discoveries. In fact, a person can be completely blind and still be sensitive to light. The part of the eye that transmits photophobia to the brain is different than the part that transmits vision. Photophobia is a neurological issue that involves communication between receptors in the eye and the brain. Between computer and device screens, fluorescent and LED light bulbs, and even sunlight, our lives are awash with this light. Blue-green light causes more photophobia than other colors. The wavelength or color of light also plays a role. The brighter the light, the more discomfort, pain, or aversion you probably feel.

The patient with photophobia experiences discomfort or pain in the eyes due to exposure to light (sunlight, fluorescent lights, TV or computer screens, or the glare from snow). The word, photophobia is derived from two Greek words: photo- вЂњlightвЂќ and phobia вЂњfear or dread ofвЂќ-hence, вЂњfear of light.вЂќ However, in medical terms, it is not a morbid fear or phobia, but rather a symptom, common in migraine, as well as ophthalmic and other neurological disorders. What is Photophobia?Дo lights seem too bright to you? Does light make your head pain even worse when you have a headache or are in a migraine attack? Do your eyes ever hurt or feel uncomfortable due to light? Do you have an aversion to light whether you have pain or not? If you answered вЂњyesвЂќ to any of these questions, you most likely have photophobia. Concussion or traumatic brain injury (TBI), and trigeminal autonomic cephalalgias (including hemicranias continua and SUNCT) can also photophobia. And, it is not the only headache disorder, cluster headache, new daily persistent headache (NDPH). Eventually, we established a company that manufactured specialized eyewear.ДЄlthough we started the company because of our personal migraine experience, we quickly learned that photophobia is a symptom of more than 40 health conditions.

My wife got so much relief that we made a few more pairs to help other people we know who experience migraine. My background is in new product development, so I put those skills to work and made exactly the glasses we envisioned for her. I had watched my wife suffer for many years, and while I could relate because of my own episodic migraine, I often felt helpless in her struggle. The problem was finding glasses that blocked enough light for the tint to be effective. Research had found that a special tint for glasses resulted in 74% fewer migraine attacks per month! When we did more reading at home, we found that the study the specialist mentioned, was part of more than 20 years of research on light sensitivity. When my wife protested that sunglasses were her only way to quell the pain, her physicianвЂ™s response excited us both.

Sunlight, light from computer monitors and TVs, and fluorescent lights triggered even more attacks. During an attack, photophobia increased her misery. Chronic migraine had made her so sensitive to light that she had to wear sunglasses indoors. вЂњWearing sunglasses indoors is increasing your sensitivity to light.вЂќ My wife and I were floored when her headache specialist made this statement.
