The light visible by our eyes is composed of red, yellow, green, blue and violet light.

Blue light is the most energetic of the visible spectrum. The more energetic the light, the more dangerous it is for the eye. This one is located just after the Ultra violet from which we protect ourselves with the sunglasses.

On the visible light spectrum, blue light is divided into two very different types of radiation. Turquoise blue light (from 455 nm to 495 nm) is recognized as vital to the body. It contributes to our awakening, our falling asleep, our well-being in general.

On the other hand, blue-violet light (from 380 nm to 455 nm) accelerates the aging of our cells and generates headaches/eye strain. Partly filtered by the crystalline lens, it penetrates deep into the eye and hits the retina in its central part.

The effects of blue light on sleep and circadian rhythms are no longer in question. The so-called circadian rhythms are those regulating the time of wakefulness and sleep in individuals and are impacted by a hormone called melatonin. Blue light causes a certain level of alertness in humans, degrading the secretion of melatonin and therefore the quality of sleep.

Insomnia, headaches, eye strain: if you are prone to these symptoms, chances are you need blue light glasses to improve your overall well-being.

Blue light is a high-energy light that is emitted by the sun. It is the main source of emission of this light. However, we note that blue light is also ubiquitous in artificial light sources, especially in energy-saving lighting (LED) and electronic displays such as smartphones, tablets and computers, but the level of illumination is too low. It is this moderate illumination that makes blue light dangerous for our eyes. Computer screens as well as telephone screens are generally at a distance close to our eyes. Thus the length of the rays of light is too small not to impact us.

Excessive exposure to these sources whose harmful blue light is considered too aggressive is proven to be the origin of certain pathological changes.

You can protect yourself with a pair of anti blue light glasses.

There are several solutions to reduce the impact of blue light:

• Limit the use of computer, phone and tablet screens

• Adapting your LED bulbs and favoring warm white temperatures

• Put a filter on your screens, whether it is a night mode or a dedicated application

• Adopt anti blue light glasses

This is the last solution that will provide the best protection against blue light.
