What are FL-41 lenses? FL-41 is a specialized tint applied to lenses, scientifically proven to block specific wavelengths of light that trigger eye pain, dizziness, and headaches. These lenses are widely used as a therapeutic tool for people managing photophobia, post-concussion syndrome, and migraine relief.
The Science
Why FL-41 Works
Blue-Green Light Blocking These lenses filter out a significant portion of blue and green light — specifically in the 480–520 nm range — which are the most common wavelengths to trigger light sensitivity, eye pain, and headaches.
Soothes Fluorescent & Screen Glare Originally developed by researchers to mitigate the harsh, flickering glare of fluorescent lights in office settings and from computer screens — some of the most persistent everyday triggers for photosensitive individuals.
Reduces Symptom Frequency Clinical studies have shown that FL-41 filters can significantly reduce the frequency and severity of migraines in people who experience light-triggered episodes.

▲ Targeted filtering zone: 480–520 nm
Clinical Evidence
What Studies Have Found
Clinical studies examining FL-41 filters have reported meaningful improvements in migraine frequency and light-triggered discomfort for photosensitive individuals.
74%
fewer migraine attacks reported in studies
76%
improvement in light-triggered discomfort
80%+
reduced overall headache impact reported
Results vary by individual. These figures are based on observational clinical studies involving FL-41 lens filters.

Still good . I a used only 2 days
Best
It is big, not suits my face cut. Maybe smaller size suits.
Quality of glass is good. Glass is effective in stopping glares from oncoming vehicles. However, at close range I found difficulty in figuring out the proximity of vehicles. The frame looks bigger on my face. I would have liked more if it had a smaller size available as well.
I got the damage piece and i requested for the new one but still didn't receive please exchange my product with some different model
Frame is good, so is the quality, value for money product however during night drive is extremely helpful. 4/5* . Keep up the quality.
