• Does your child use a tablet or smartphone?
• Does your child like to watch a film or a series in the evening?
• Does your child have problems falling asleep or staying asleep?

Then the use of Blueblocker glasses can be useful for your child.

The crucial and biggest problem of blue light after sunset is its effect on the nervous system. After dark, the light tricks the brain into thinking it is the wrong time of day. This interrupts the sleep cycle and can have a negative effect on your child's health, especially over a longer period of time. Blueblockers that block 100% blue light can help your child protect the sleep cycle and improve sleep quality.

Difference between LEDs and fire

LED spectrum

We speak of blue light at a wavelength of approx. 380 to 495 nanometres (nm). It is short-wave and very energy-rich light. Modern displays, LEDs and energy-saving lamps have a disproportionately high share of blue light. This stimulates certain photoreceptor cells and can lead to a dysregulation of the sleep-wake rhythm. This can have a negative effect on your child's hormones and metabolism. (1)

Fire (candlelight)

Before we were able to turn night into day through the invention of electricity, there were only natural sources of light in the form of fire. The big and decisive difference to today's light sources is the distribution of the light spectrum. Blue and green are hardly present in candlelight, as can be seen in the graph. Furthermore, fire has no flicker effect, which can stress the nervous system. Therefore, fire usually has a calming effect.

A systematic review by Hester et al. (2) comes to the following conclusion:

Out of the 24 publications focusing on sleep, there was substantial evidence for blue-blocking glasses being a successful intervention for reducing sleep onset latency in patients with sleep disorders, jet lag, or variable shift work schedules. Given the well-established biological mechanism and clinical research showing that blue-blocking glasses are effective for inducing sleep, they are a viable intervention to recommend to patients with insomnia or a delayed sleep phase.

Why is there no 550 model for children?

In our practice, we have found that children's nervous systems still react strongly to colours. Apart from that, especially younger children feel much more comfortable with a lighter version and prefer to wear it.
