What are FL-41 migraine glasses and how do they work?

FL-41 Q & A

FL-41 Lenses: A Comprehensive Overview

FL-41 lenses are a specialized type of eyewear designed to alleviate visual discomfort associated with certain light conditions, particularly in individuals who suffer from conditions such as migraines, photosensitivity, and other light-sensitive disorders. These lenses are known for their unique tint, which is specifically formulated to filter out specific wavelengths of light that can trigger discomfort and exacerbate symptoms in susceptible individuals.

Key Features:

  1. Wavelength Filtering: FL-41 lenses are characterized by their rusty rose tint. This tint is not chosen randomly; rather, it is carefully selected to filter out specific wavelengths of light. In particular, FL-41 lenses are effective at blocking light in the blue-green spectrum, which is often associated with fluorescent, LED  lighting and digital screens. By doing so, these lenses aim to reduce the impact of artificial lighting on individuals sensitive to these wavelengths.

  2. Migraine Relief: One of the primary applications of FL-41 lenses is to provide relief to individuals who suffer from migraines triggered by light sensitivity. Research suggests that certain wavelengths of light can contribute to the onset of migraines in susceptible individuals. FL-41 lenses, by selectively blocking these wavelengths, aim to reduce the frequency and severity of migraine attacks.

  3. Photophobia Management: Photophobia, or extreme sensitivity to light, is a common symptom in various medical conditions, including post-concussion syndrome, chronic fatigue syndrome, and certain neurological disorders. FL-41 lenses are prescribed to manage photophobia by minimizing the discomfort caused by exposure to bright or artificial light sources.

  4. Computer Vision Syndrome: With the increasing prevalence of digital devices in our daily lives, many people experience symptoms of eye strain, headaches, and fatigue related to extended screen time. FL-41 lenses can be beneficial in reducing these symptoms by mitigating the impact of certain wavelengths of light emitted by screens.

Prescription and Non-prescription Options:

FL-41 lenses are available both as prescription eyeglasses and non-prescription versions like clip-ons or fit-overs. Individuals with specific vision correction needs can enjoy the benefits of FL-41 technology tailored to their prescription, while those without prescription requirements can use non-prescription options for specific activities or as a preventive measure.

Considerations and Limitations:

While FL-41 lenses can be highly effective for many individuals, it’s essential to recognize that their efficacy may vary from person to person. Additionally, these lenses may not provide a complete solution for everyone, and other factors contributing to light sensitivity should be addressed in conjunction with eyewear solutions.

In conclusion, FL-41 lenses represent a specialized and innovative approach to managing light sensitivity and related symptoms. As technology continues to advance, these lenses may see further refinement and application in addressing a broader range of visual and neurological conditions. Individuals experiencing light sensitivity or related symptoms should consult with an eye care professional to determine the most suitable solutions for their specific needs.
We confirm that our FL-41 lenses are 100% genuine. We have followed the same fourmula used in the original research carried out by Birmingham University. However, it’s always a good idea to consult with a healthcare professional or an optometrist for personalized advice, especially when it comes to medical conditions and treatments. If you have more questions or if there’s anything specific you’d like to know, feel free to ask!
