Lesa Glasses for Migraine and Epilepsy

Principle

Epilepsy tint
A deep blue with low light transmission. This lens helps to prevent and stop an epileptic seizure. The special colour simulates a resting or sleeping position and quickly calms the subject.

Migraine/Epilepsy Preventive Tint
Worn all the time, this tint reduces visual stress and softens light flashes. This dual action significantly reduces migraine and/or epilepsy attacks.

Magelis Classique - The anti-migraine shade.
Migraines are frequent headaches. It is generally disabling because it can interfere with the sufferer's activity. A migraine lasts between 4 and 72 hours. Symptoms include phonophobia, photophobia, nausea and even vomiting, and are generally aggravated by physical exertion. Migraines are three times more common in women than men, and often occur between the ages of 10 and 40. There are various causes of migraine, with the ophthalmic factor frequently put forward as a cause.

Magelis tint acts on different levels. It eliminates harmful and disabling blue light and acts on light transmission and perception. As well as acting on neurotransmitters by altering the visible spectrum, Magelis also limits light transmission, which generates additional stress. It is therefore beneficial in the fight against photophobia.
Worn all the time, this tint reduces visual stress and attenuates flashes of light.
This dual action significantly reduces migraine and/or epilepsy attacks.
epileptic seizures.
Light transmission: available in 5 different light transmissions, each patient will be able to choose intensity to suit their sensitivity.

Magelis Akebi - A winning combination of headaches prevention and contrast.
Some people are so sensitive to light that they suffer from headaches.
It's mainly wavelengths below 500 nm that cause this phenomenon. In other words, mainly blue light. By effectively and precisely filtering the right wavelengths, a lens can inhibit chemical behaviour in the brain or regulate a wearer's circadian cycle.
The eye contains light-sensitive retinal ganglion cells that generate melanopsin.
The function of melanopsin is to facilitate colour vision in bright light. It is mainly released by exposure to blue light. Some studies have shown that light-related ophthalmic headaches may involve this molecule. 

The Akebi tint eliminates harmful and disabling blue light and acts on light transmission and perception. As well as acting on neurotransmitters by modifying the visible spectrum, Akebi tint limits the transmission of light, which generates additional stress. It is therefore beneficial in the fight against photophobia. When worn continuously, this tint reduces visual stress and attenuates flashes of light. This action significantly reduces migraine and/or epilepsy attacks. Akebi also significantly improves contrast vision.
This may also be suitable for visually impaired people.
Light transmission: available in 5 different light transmissions, each patient can choose the intensity that best suits their sensitivity.

The glasses are used as standard non-refractive sunglasses and are available in different sun protection categories from 1 (indoor or cloudy weather) to 3-4 (outdoor, sunny weather) and tints. Category 4 - not suitable for driving!
