If fluorescent lights, LED flicker, screens, or bright stores trigger your migraines… FL-41 lenses might change your life.
Originally studied for migraine and light sensitivity at the University of Utah, FL-41 is a specialty rose tint designed to filter specific wavelengths of light linked to photophobia and migraine discomfort.
Newer research using fMRI brain imaging showed FL-41 lenses actually reduced activation in pain and light sensitivity pathways in the brain. 🤯
Patients often report:
• fewer migraine triggers
• less eye strain from screens
• improved comfort under LED & fluorescent lighting
• reduced sensitivity to glare and flicker
This is NOT the same as standard “blue light” glasses.
FL-41 targets the wavelengths most associated with migraine and photophobia.
