What Causes Light Sensitivity?

FL-41 tinted lenses (called migraine glasses) originated in the 1990s to help with fluorescent lights and it’s now used to help with light sensitivity and migraine — a disorder that affects 1 in 4 households in the United States. And while a lot of things can bring on a migraine attack, it turns out that light is one of the most common triggers.

FL-41 is a type of specialty eyewear tint designed for people with light sensitivity and most commonly recommended for patients with migraine, post-concussion syndrome and dozens of other light-sensitive conditions. It was first introduced back in the early 1990’s as part of a research study that explored how glasses coated with this precision tint might help alleviate the migraine symptoms of young children—particularly against the harm of fluorescent lighting. Within the last decade, advancements in the understanding of photophobia and light sensitivity have precipitated more widespread availability of FL-41 to patients all over the world.

Axon Optics’ FL-41 tint is best for indoor lighting conditions. They’re designed to block only the harmful types of light and let the rest in, so dark adaptation won’t be a problem. FL-41 tint can also be applied to outdoor sunglasses. This can give you an extra measure of protection from not only bright UV light, but blue light specifically.
