At least 7% of the population1 suffer from migraine symptoms. These include debilitating headache, nausea, patterns appearing in the field of vision and sensitivity to light.

The triggers can be notoriously difficult to pinpoint and for many, may never be identified. However, light emitting devices such as screens, sunlight, indoor lighting, flicker and other intense sources can be a common migraine trigger and are also commonly reported as causing heightened sensitivity during and after an attack. In fact it is one of the most commonly identified causes.

Up to 40% report that light can trigger2 migraine symptoms or cause sensitivity during an attack.3

This means that over 8 million people in USA and 14 million in Europe identify that sensitivity to sources of light is one of the causes of migraines or amongst their primary migraine symptoms.
