Blue light and migraine: how to manage visual triggers

Health and wellness

For those who live with migraines, light can be both a trigger and an aggravator. Understanding this relationship helps reduce exposure to what causes harm.

This article is for informational purposes only and does not replace medical advice: migraine has many causes and treatments, and a professional should guide your case.

Light Sensitivity and Migraine

Many people with migraines experience photophobia: discomfort or pain from bright light. Intense lights, glare, and flickering screens can be especially difficult during an attack, and even act as a trigger in sensitive individuals.

Eye Strain as a Cumulative Factor

Long hours in front of a screen strain the eyes and can lead to tension in the forehead and neck. This accumulated effort sometimes contributes to headaches. Breaks, good lighting, and reducing glare help lessen this burden.

Measures that can help

• Reduce the brightness and glare in your workspace.
• Take real breaks and apply the 20-20-20 rule.
• Avoid the screen being the only light source in the room.
• Filter out some blue and intense light during long workdays.
