Category Archives: FL-41 Glasses and Sunglasses
FL-41 is a tint for eyeglasses that preferentially blocks blue-green light and was originally developed to reduce sensitivity to fluorescent lighting, but has been shown effective in mitigating the frequency and severity of migraine, blepharospasm, and other light-sensitive conditions.
Light is often what triggers pain and migraine sufferers frequently complain of light sensitivity during their attacks. Dr. Bradley Katz, a founder of Axon Optics, is a neuro-ophthalmologist at the University of Utah and studies how precision tinted eyewear can provide relief to patients with light sensitive conditions.
A study performed by researchers at the University of Birmingham, England tested a group of migraine sufferers by having them wear glasses with the tint FL-41. Participants experienced a reduction in the number of migraines, from over 6 episodes per month to under 2 episodes per month. Axon Optics lenses are based on the heritage of this FL-41 tint. Our lenses have been optimized to offer better visual quality and appearance and are preferred by users to the original FL-41. Furthermore, our lenses have the option of a multipurpose anti-reflective, anti-fingerprint, and anti-scratch coating.
