Light sensitivity is one of the most underestimated migraine triggers. For many people, certain light wavelengths actively provoke migraine attacks, especially blue and green light from screens, fluorescent lamps, and LED lighting.
FL-41 glasses are clinically studied migraine lenses that filter specific wavelengths known to overstimulate the trigeminal nerve and visual cortex.
What science shows:
-
FL-41 lenses reduce photophobia and visual discomfort
-
They lower cortical hyperexcitability linked to migraine attacks
-
Studies show fewer migraine days and reduced attack severity in sensitive patients
Unlike standard blue-light glasses, FL-41 filters a precise light spectrum, not just brightness. This makes them especially helpful for:
-
screen work
-
fluorescent office lighting
-
migraine with aura
-
chronic light sensitivity between attacks
FL-41 glasses do not treat migraine directly, but they reduce one of the most powerful external triggers – visual stress.
Used consistently, they act like a protective shield, helping prevent attacks before they start.
