OKNO — Specialized Light Therapy Eyewear FL-41 Migraine Relief Glasses Therapeutic-grade lenses engineered to filter the specific light wavelengths most commonly linked to migraines, photophobia, and light-triggered headaches. Photophobia Relief Migraine Support Post-Concussion Digital Eye Strain Indoor & Outdoor What are FL-41 lenses? FL-41 is a specialized tint applied to lenses, scientifically proven to block specific wavelengths of light that trigger eye pain, dizziness, and headaches. These lenses are widely used as a therapeutic tool for people managing photophobia, post-concussion syndrome, and migraine relief. The Science Why FL-41 Works Blue-Green Light Blocking These lenses filter out a significant portion of blue and green light — specifically in the 480–520 nm range — which are the most common wavelengths to trigger light sensitivity, eye pain, and headaches. Soothes Fluorescent & Screen Glare Originally developed by researchers to mitigate the harsh, flickering glare of fluorescent lights in office settings and from computer screens — some of the most persistent everyday triggers for photosensitive individuals. Reduces Symptom Frequency Clinical studies have shown that FL-41 filters can significantly reduce the frequency and severity of migraines in people who experience light-triggered episodes. 380 nm 500 nm 700 nm ▲ Targeted filtering zone: 480–520 nm Clinical Evidence What Studies Have Found Clinical studies examining FL-41 filters have reported meaningful improvements in migraine frequency and light-triggered discomfort for photosensitive individuals. 74% fewer migraine attacks reported in studies 76% improvement in light-triggered discomfort 80%+ reduced overall headache impact reported Results vary by individual. These figures are based on observational clinical studies involving FL-41 lens filters.
