The Science Bit & FAQs

what makes FL -41 Lens better?

Backed by extensive research, FL-41 lenses have been proven to provide relief to those with light sensitivity.

Commonly referred to as 'Migraine Glasses' and different to 'anti blue light' lenses, FL-41 lenses filter out more light in the blue-green spectrum, particularly wavelengths around 480-520 nm. This range of light is often associated with visual discomfort and can trigger migraines and photophobia.

Why not just use sunglasses?

Wearing sunglasses indoors as a protective measure for photophobia and light sensitivity can make the problem worse in the long run. Studies show that patients will 'dark adapt' thier eyes and further aggrivate sensitivity to light. One study stated 'The use of sunglasses indoors should be discouraged, patients should be encouraged to transition to the use of FL-41 or other tints for indoor light sensitivity'
