Do Flickering Lights Cause Headaches?

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. Fluorescent light contains invisible pulsing, which is likely why so many report it as a migraine trigger.

Why do I get headaches when I see flashing lights?

Some people experience flashes of light that appear as jagged lines or “heat waves” in both eyes, and they can last for up to 20 minutes. These types of flashes are usually caused by a spasm of blood vessels in the brain, which is called a migraine. If a headache follows the flashes, it's called a migraine headache.

Does Whitelight cause headaches?

As we showed previously, blue light remains a central component of LEDs and continues to be a primary culprit for worsening migraine attacks and sensitivity to light. In addition, red- and white-colored LED lighting also activate areas of the brain that are suspected of producing photophobic and migraine pain.
