Beschrijving Multilens Nelli FL-41 migraine glasses brown
An ode to the Nelli FL-41
Many benefits in one go
It is no longer necessary to sit in the dark, completely avoid screens or constantly walk around wearing sunglasses. Migraine glasses provide the benefits of all these measures in one, and you'll also look more stylish immediately!
Why the Nelli FL-41 migraine glasses?
The glasses use so-called FL41 filtered lenses, which is why they are also called "migraine glasses". The filter ensures that only the most powerful light - certain wavelengths from blue and green light - does not reach your eyes. This also improves contrast and even visual acuity.
Fluorescent light (or other bright lighting) and computer, TV and other screens emit a lot of irritating blue light. Wearing the Nelli computer glasses with a blue light filter relieves stress on your eyes, preventing headaches, visual stress and Blepharospasm. In addition, your sleep is improved because blue light prevents the production of the sleep hormone.
People with migraines will recognise wearing sunglasses (even indoors) to combat migraine symptoms. The problem with this is that your eyes get used to the dark, which can worsen your light sensitivity. That's why the FL41 filter, or UV filter, only blocks the most sensitive lights. This way, your eyes are protected without making them "lazy".
The stylish frame of the glasses is available in two colours: brown and black. Furthermore, the frame is very lightweight, which greatly enhances wearing comfort. The glasses come with a leather case and a cleaning cloth.
What makes migraine glasses so good?
Migraine glasses are a simple solution to a complex problem. Light-sensitive individuals previously had to take many measures to prevent headaches and other discomforts. And people who have to look at a screen a lot know the disadvantages of this. Now there is one solution that protects your eyes from harmful light and can make your days much more comfortable: migraine glasses.

Where and how often you should wear the glasses varies per person and situation. To gain clarity for yourself, it is best to determine in which situations you experience symptoms of light sensitivity. These are the moments to wear the glasses. Please note: it is not recommended to wear the glasses while driving at night.
