FL-41 Fit-over Glasses
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 Fit-over style fits comfortably over most prescription frames.
We offer free US shipping and 60-day, no-hassle returns.
Fit-over glasses measure: 6.2" (width), 6.2" (Length), 1.8" (height).
