FL-41 Glasses are a Thing of the Past
The Highest Scientific Standard
An independent, double-blind, randomized, placebo-controlled clinical trial
Avulux is the only light sensitivity lens to ever be proven effective at this highest standard of clinical testing.
Avulux lenses were designed to help people with migraine manage the impact of light.
Avulux’s lens design directly aligns with the most recent research linking specific wavelengths (or colors) of light to increased pain and light sensitivity.
Avulux is patented, clinically proven, made with a revolutionary lens technology, and the lenses available to customers today are the lenses that were proven in the Avulux clinical trials.

FL-41 Glasses and Lenses
FL-41 was a lens created in the 1980s to help people with light sensitivity caused by flickering fluorescent lighting. There are various optical labs and vendors that sell the FL-41 tint, and there are inconsistencies between lenses. There is no clinical evidence showing FL-41 provides light sensitivity nor migraine relief during a migraine attack. There are also new light sources like LED, digital screens, and even sunlight that sensitive individuals are faced with in their daily lives that remain unaddressed by FL-41 lenses.
Lens Technology Has Evolved With New Research
It’s only within the last 10 years that the medical world has come to better understand how light plays a role in pain and how it can affect and worsen migraine symptoms. FL-41 mainly blocks blue wavelengths of light, and there has since been clinical evidence, through research conducted at Harvard, showing that blue light isn’t the only culprit in worsening migraine pain (so generic blue light glasses are also falling short). Exposure to amber and red light can be just as painful (as they're also pain and light sensitivity triggers) while low-intensity green light can reduce migraine pain or keep it consistent.
New Light Sensitivity Glasses That Help People with Migraine - Avulux
Avulux has actually been shown to effectively manage the impact of light by filtering harmful light during a migraine attack. Avulux is the only lens that has been able to show this in a clinical setting. Avulux targets the most harmful blue, amber, and red light while allowing in soothing green light to help you get through the day. Avulux glasses can be used as indoor glasses and they also work well for outdoor use.
Why is it that you may have heard more about FL-41 than Avulux? FL-41 has had 40 years to spread the word, while Avulux was released to the public in 2018.
Know what else was widely used in the 1980’s? Landline telephones. We’ve all moved on to our smartphones since then. Lens technology has evolved just as much.
