Assisting Patients With Migraines, Blepharospasm, & Other Light-Sensitive Conditions

FL41 lensThe FL-41filter is a ‘boysenberry-ish’ colored tint that we have found to be useful in patients with migraine headaches, blepharospasm, light triggered seizures, CVS (Computer Vision Syndrome) and other light-sensitive/triggered conditions. FL-41 was first described in a research project that took place in Birmingham, England in the early 90s. In this study, children with migraine headaches wore FL-41 filtered spectacles.

The researchers found that wearing the FL-41 filter improved the light sensitivity in these children, as well as lessened the frequency and severity of their migraine headaches. Since that time, FL-41 filtered lenses have been used to treat these and other conditions.

FL 41 LensAided by funding from the Benign Essential Blepharospasm Research Foundation, we have found that blepharospasm and migraine patients suffer more from light sensitivity, vs. people who do not struggle with these conditions. We have also found that when these patients have had their light sensitivity treated, their blepharospasm and migraine symptoms have improved.

Recently, we have tested FL-41 filtered lenses, head-to-head, against conventional gray sunglasses and standard rose tinted spectacles.  We have found that the majority of patients prefer wearing FL-41 filtered spectacles.
