Outdoor Fl-41 Light Sensitivity Sunglasses (Polarized)
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.
Outdoor Fl-41 glasses are also effective at reducing photophobia and light sensitivity that does not result in migraines, particularly light sensitivity caused by sunlight. Fl-41 lenses block 80% of the blue wavelengths that can trigger eye pain, dizziness, and headaches.
The polarization on our outdoor sunglasses additionally blocks vertical light, helping to reduce glare.
Glasses measure 5.6" (width), 1.75" (height), 6.5" (Length).
