What Are FL-41 Glasses
Not just rose-tinted. Precision-filtered.
FL-41 is a rose-amber tint developed to filter a specific band of light, the 480 to 520nm blue-green range, that has been identified as the primary wavelength responsible for activating migraine-related light sensitivity pathways in the eye.
A specialised population of retinal cells, intrinsically photosensitive retinal ganglion cells (ipRGCs), contain the photopigment melanopsin and are maximally sensitive to light in this exact wavelength range. In migraine sufferers, this pathway is believed to be sensitised or hyperactivated, meaning that even ordinary levels of blue-green light can trigger or intensify an attack.
FL-41 is distinct from generic blue-light glasses, which filter wavelengths below 450nm associated with screen flicker and circadian disruption. It is also distinct from dark sunglasses, which can paradoxically worsen photophobia over time by further sensitising the visual system through dark adaptation.

The Research
What the clinical evidence shows
University of Birmingham, published in Cephalalgia
Patients wearing FL-41 tinted lenses experienced a significant reduction in migraine frequency compared to those wearing a control grey tint. The study identified the blue-green spectral range as the primary activating wavelength for migraine-related photophobia.
University of Utah, photoreceptor sensitivity study
A narrow-band green wavelength around 530nm was the most tolerable light for migraine sufferers during an attack, further validating the FL-41 approach of filtering the surrounding blue-green band while allowing some mid-spectrum light through.
FL-41 glasses are not a cure for migraine and are not a substitute for medical advice. Results vary between individuals. Please consult your healthcare provider for comprehensive migraine management.
Who Benefits
Is FL-41 right for you?
FL-41 glasses are not appropriate for every patient, but they can offer meaningful benefit for a range of conditions where light sensitivity is a primary complaint.
Migraine Sufferers
Light is one of the most common migraine triggers. FL-41 glasses are clinically studied to filter the blue-green wavelengths that activate sensitised pain pathways during and between migraine attacks, particularly in environments with fluorescent lighting or screen glare.
Chronic Daily Headache
Patients with persistent headaches that have a photophobic component may find that reducing ambient blue-green light load helps lower headache frequency. FL-41 is worn during work hours or in high-fluorescent environments.
Post-Concussion Light Sensitivity
Light sensitivity is one of the most common and persistent symptoms after mild traumatic brain injury. FL-41 lenses are increasingly used as part of post-concussion visual rehabilitation, providing a filtered visual environment while the brain recovers.
Blepharospasm
Involuntary eyelid spasm is frequently associated with light sensitivity. Research has shown that FL-41 tinted lenses can reduce blink frequency and spasm severity in blepharospasm patients by reducing the light input that triggers the reflex.
Screen-Related Migraine Triggers
For patients whose migraines are consistently triggered by prolonged screen use, FL-41 glasses for computer work may reduce the cumulative blue-green light exposure that contributes to triggering an attack. They are distinct from standard blue-light glasses.
General Photophobia
Whether your light sensitivity is associated with medication side effects, autoimmune conditions, or is idiopathic in nature, FL-41 filtering can reduce the discomfort of light exposure in everyday indoor environments.

FAQ
Common questions
What are FL-41 migraine glasses?
FL-41 migraine glasses are spectacles fitted with a precision rose-amber tint that filters the 480 to 520nm blue-green wavelengths of light. This specific wavelength range is known to activate the light-sensitive pathways that are hyperactivated in migraine sufferers. FL-41 lenses are distinct from generic blue-light glasses and have been the subject of peer-reviewed clinical research.
Do migraine glasses actually work?
Clinical research published in the journal Cephalalgia, conducted at the University of Birmingham, found that patients wearing FL-41 tinted lenses experienced a significant reduction in migraine frequency compared to those wearing a control grey tint. FL-41 glasses are not a cure for migraine, but they are a clinically studied tool for managing light-triggered migraine and photophobia. Results vary between individuals.
Can I get FL-41 glasses with my prescription?
Yes. At Prime Optometrists we offer FL-41 lenses in prescription (including single vision and available lens indices 1.50, 1.60, and 1.67) and non-prescription formats. Prescription orders are reviewed by Dr Zobaida Tahiri before your card is charged.
Do you deliver migraine glasses across Australia?
Yes. We deliver FL-41 migraine glasses to all states and territories in Australia via Australia Post. Standard delivery is free. Express delivery is available at checkout.
Are FL-41 glasses better than sunglasses for migraines?
FL-41 glasses are designed for indoor use in environments with fluorescent lighting, screens, or artificial lighting. Dark sunglasses worn indoors can paradoxically worsen photophobia over time by further sensitising the visual system through dark adaptation. FL-41 lenses reduce the specific wavelength that triggers light sensitivity without making the environment excessively dark.
What conditions benefit from FL-41 glasses?
FL-41 glasses are clinically studied for migraine and photophobia. They may also benefit patients with chronic daily headache, blepharospasm, post-concussion light sensitivity, and those with light sensitivity from other causes. They are increasingly used as part of post-concussion visual rehabilitation.
Are FL-41 glasses safe to wear?
FL-41 glasses are safe optical lenses. They are not a therapeutic device but precision-tinted spectacles. As with any tinted lens, they are not suitable for driving at night. If you have a medical condition, please also consult your treating physician regarding your overall management.
