FL-41 is a lens tint that has been shown to reduce the impact of migraine attacks in clinical studies. But what does FL-41 tint look like? Are all FL-41 glasses the same? The answer is a resounding no.
An early research project from the University of Utah Medical Center evaluated whether patients were getting the same benefit from therapeutic lenses (or lenses with FL-41 tint) from different vendors. Surprisingly, the study found wide variations in the quality, lens color, spectral characteristics, and optical densities of lenses purchased from different optical shops and laboratories.
Each line on the graph below represents FL-41 lenses from 5 different vendors. The light shows how much light passes through the lens at different light wavelengths. As you can see, they vary significantly. Even the color of the lens ranges from rust. to purple, to hot pink.
How Are Axon Lenses Different?
The graph shows the level of variation when using generic FL-41 tint. Axon Optics brand name SpectraShield is clinically shown to be more effective and more consistent than the generic. Here are some of the differences you’ll see when you take a closer look:
Lens Testing: We’ve tested our proprietary Axon lenses with over 500 people using clinically validated surveys. We found that nearly 90% of these people experienced a decrease in light sensitivity and migraine. On average the impact of light sensitivity was reduced by 38%. Migraine days reduced by 24%.
Lens Coatings: Axon applies over 10 premium coatings on each side of its lenses to reduce glare, scratches, and smudges. This is a $100-$150 value if purchasing a similar coating through your optical shop. The Axon lens coating has less than 0.5 reflectance which is crazy low!
More Good Light: You don’t want to wear dark lenses inside as you’ll dark adapt your eyes — think how painful it is to come out of a Movie Matinee into bright sunlight. Axon lenses let 20-70% more good light into your eye than generic lenses that have been released after Axon launched.
Continued Research: Axon Optics was founded by a neuro-ophthalmogist, photonics researcher, and optical entrepreneur. My partner, Dr. Katz, has treated literally thousands of patients with light sensitivity and/or migraine. We use profits from Axon Optics to fund additional research for new products related to migraine and light sensitivity.
Correct Color: Generic lenses are red, rust, purple, rose, orange, green, etc. It can be difficult to know what you are getting with out there, which is why we’ve actually tested our lenses as described above.
Extras: You receive an eyeglass case, microfiber pouch, and a 1-year warranty. All non-prescription frames have a 100% money back guarantee and a no-questions-asked return policy within 30 days. Feel free to try them out.
You can see hundreds of user experiences for insight into these lenses. If you really want to dig in, here is a long, but relevant history on the use of tinted lenses for migraine and light sensitivity.
How Should I Choose A Therapeutic Lens?
Look at the research and consider the source. Axon Optics was founded by researchers at the University of Utah. One of the founders, Dr. Bradley Katz, is a neuro-ophthalmologist who has worked with thousands of patients. He has been recommending and perfecting therapeutic eyeglasses for patients with light sensitivity for over 15 years.
The Axon lenses, called Spectrashield FL-41™, have been used by tens of thousands of people and have been shown to reduce the impact of migraine in over 90% of users. Our SpectraShield FL-41™lens is proprietary, and has been fine-tuned over the last 20 years many years by Dr. Katz. Each lens comes with premium coatings that block glare and prevent finger smudges and scratches.
Here is some feedback from an optical shop that is recommending Axon Eyewear: “I did a quick in-office test of [various vendors of FL-41]. Your tint won, especially with the office people who suffer from migraine headaches.”
