Many people with migraines experience photophobia, an abnormal sensitivity to light. Photophobia can occur both during a migraine attack and between attacks, causing both natural and manufactured light to cause pain and discomfort.

For some people, light may act as a trigger for a migraine attack.

Photophobia can cause people to avoid going outside on sunny days and seek shelter in darkened rooms. However, light isn’t always avoidable.

One of the ways some people with migraine combat photophobia and prevent migraine attacks is by wearing tinted glasses.

Available in Prescription and non-prescription lenses.

How are migraine glasses different from regular sunglasses?

Researchers have found that only certain wavelengths of light causes photophobia, which makes finding migraine glasses that filter these specific wavelengths very important.


Currently, the FL-41 tint is the only known option that specifically targets this light without being too dark like sunglasses.

Outdoor FL-41 lenses are also available and offer more protection than regular sunglasses. However, sunglasses are designed to block the bright sunlight, and while they can be worn indoors, prolonged wear of sunglasses indoors may actually cause the eyes to become more sensitive to light, as the eyes adapt to the darker shading of sunglasses.


What research has been done on migraine glasses? Several clinical trials have studied the effect of tinted glasses in people with migraine. One study conducted in 2002 compared glasses that filtered conventional white light with a control pair of glasses that were just tinted but didn’t filter light. The participants used the different glasses and recorded the frequency of their migraine attacks in a headache diary. The frequency of attacks was marginally lower when the optimal glasses that filtered out light were used.

Another study involved 20 children with migraine, conducted in 1991. The children were randomly assigned to wear glasses with either a FL-41 rose tint or a blue tint for four months. The frequency, duration, and severity of migraine attacks were recorded. After one month’s wear, all the children had an improvement in the frequency of migraine attacks, but only the children wearing the rose-tinted glasses had this improvement sustained up to four months. In the rose glass group, the frequency of migraine improved from 6.2 per month to 1.6 per month.

 Based on published research, the best tint option for migraine and photophobia relief is a filter capable of blocking the critical 480-520nm wavelengths.

Does certain light trigger or worsen photophobia? The answer is a resounding yes! Fluorescent lighting, sunlight, and computer or mobile device screens can make things worse for someone with light sensitive eyes. Fluorescent lights have been shown to double incidences of headaches and migraine attacks among office workers, and they are repeatedly cited as an issue for patients with a history of traumatic brain injury.

Not all wavelengths of light cause the same types of pain. Some wavelengths, particularly in the blue part of the spectrum, irritate nerves in the eye and brain and trigger pain. And these wavelengths are everywhere in natural and artificial light. Fluorescent lights are particularly bad because of how the brain perceives them. 

The Fluorescent Light Nightmare: Fluorescent lights make many people feel sick, because they pulse faster than you can consciously see but the brain still acknowledges this pulsing as rapid signals from the nerves of the eye. Rapidly repeating patterns, such as blinking lights or even stripes of the right width, can cause headaches, eyestrain, and nausea. For some people, it can even trigger migraines. Fluorescent lights can irritate our brains without us even consciously aware of it, and the use of fluorescent lighting is growing, exposing us to more and more pulsing. As scary as this is for us, there’s good news. Fluorescent pulsing is most intense at certain wavelengths. That means if you filter those specific wavelengths, you can filter the pulsing.
