FL-41 Clip-on Light Sensitivity Lenses
Fl-41 is the tint most commonly recommended by doctors and specialists for the prevention of light sensitivity and migraines. One study found that the use of Fl-41 glasses reduced the number of migraines by an average of 74% in a four month period.
Fl-41 glasses are also effective at reducing photophobia and light sensitivity that does not result in migraines, particularly light sensitivity caused by florescent lighting and computer screens.
Our Fl-41 glasses are suitable for both indoor and outdoor use. Our clip on lenses fit comfortably on most prescription frames.
We offer free US shipping and 60-day, no-hassle returns.
Lenses measure 132 mm (width), 41 mm (height).
