FL 41 – Tester

FL-41 Glasses for Light Sensitivity & Photophobia Relief

Are you sensitive to light?

If you suffer from photophobia (light sensitivity), simply wearing darker lenses isn’t the solution. While darker sunglasses block more light, they often reduce your overall visual quality and can make your symptoms worse over time. True relief comes from wearing the correct combination of specialized lenses and frames.

Conditions That Benefit From FL-41 Lenses:

Our specialized migraine and light-sensitivity glasses offer relief for:

• Migraine headaches and vestibular migraines

• Blepharospasm

• Computer Vision Syndrome (CVS)

• Sensitivity to fluorescent lighting and LED bulbs

• Motion sickness and visual vertigo

• Nighttime driving discomfort and glare

Why Choose Our FL-41 Filter Lenses?

Originally developed following 1990s research by Birmingham University, specialized tinting was shown to dramatically reduce the triggers associated with migraines, blepharospasm, light-triggered seizures, and eye strain.

The FL-41 lens is a distinctive rusty rose-coloured tint designed to block specific wavelengths in the light spectrum—most notably the flickering blue light emitted from indoor fluorescent lighting and digital screens. Featuring a 50% absorption rate (ABS), these lenses help minimize eyestrain, tension headaches, and chronic migraines.

The Perfect Frame Design for Maximum Protection

Lens technology is only half the solution. To prevent ambient light from leaking in, these frames feature a wrap-around design that contours naturally to your head, paired with thick side arms to block peripheral light. All lenses include 100% UVA and UVB protection alongside the FL-41 therapeutic filter.

Try Risk-Free: Our 30-Day Guarantee

Fitted with authentic FL-41 filter lenses, you can test these frames at home to see if you are among the 85% of users who experience immediate relief. If you aren’t completely satisfied, simply return the glasses in their original box for a full refund.

Medical Disclaimer: When treating any chronic medical condition, we always recommend consulting your GP or an ophthalmologist (eye doctor) before purchasing therapeutic eyewear.
