The Photophobia Spectrum: Harnessing Green Light

80% of migraine attacks are associated with extreme light sensitivity. Research from Harvard Medical School has shown that while blue and red light wavelengths worsen migraine pain, a narrow band of green light can actually reduce pain intensity.

Dark Mode for Recovery

High-contrast, dark environments protect the ocular nerve from over-stimulation. This is why the Relief app uses an exclusively dark UI — reducing blue-light exposure during an attack lowers the electrical noise in your visual cortex and speeds recovery.
