SCREENKEEPERS ARE GOOD FOR YOU!
One major drawback of the ongoing digitisation of modern society is the 'blue light effect' of screens and equipment. LED lighting in devices is particularly strong in the blue range, which may have negative effects due to strain on the eyes. This is also referred to as Computer Vision Syndrome (CVS). Most people are very familiar with the biggest drawbacks:
Screenkeepers with blue filter (select this option when ordering) therefore include a blue light and UV filter to neutralise these effects. The user will not notice any difference, the filters simply do their job.
CVS is widespread and ranks in the top five common problems among skilled workers; more than 40% of office workers suffer from it.
That is why the technical term of Computer Vision Syndrome, or CVS, was coined. It may sound very medical, but CVS is not an official medical condition. That does nothing to help the difficulties experienced, however:
Chances are that you have already experienced one of the 7 typical complaints of CVS.
However, in addition to these well-known complaints, 'computer eyes' pose another problem: they increase the risk of myopia and, later in life, of far-sightedness. It may even lead to short bursts of short-sightedness when looking at a screen for too long.
Blue light mimics sunlight, or daylight, which can disrupt the human biological clock. The biorhythm is driven by the suprachiasmatic nucleus in the hypothalamus, which in turn activates the pineal gland in the brain to produce the sleep hormone. Blue light inhibits the production of this sleep hormone.
Looking into a blue light makes it more difficult to fall asleep. Light influences the central internal biological clock of people and animals and therefore also their heartbeat, hormone secretion, body temperature and the sleep and wake cycle. Disturbances in the natural sleep rhythm may have numerous negative effects on people's emotional and mental state. Performance deteriorates, while health risks increase.
The effects of blue light and computer use (including tablets and mobile phones) have been relatively limited for most of today's adults, but new generations are starting to use phones and tablets at an increasingly younger age. The effect of continuous screen time with developing eyes is therefore the subject of a great deal of research conducted by ophthalmologists.
The question is, what are we doing to our children's eyes?
Staring at a screen for more than 4 hours a day is harmful to them, but some of them do so for much longer periods. Whether it involves a computer screen (during the day), television screen (in the evening) or mobile phone screen (the rest of the time): they are only looking straight in front of their nose, with the focus always fixed on a screen that is about 50 centimetres away. And that has consequences. It is not surprising that more than 90% of the population needs to wear glasses sooner or later.
Unfortunately, damage to the retina caused by blue light is irreparable. This is particularly serious when it occurs at the centre of the field of vision, in the yellow spot, which leads to a reduction in visual acuity.
For these reasons, Screenkeepers provides the option of including a special blue light filter in addition to the screen protection. You can specify this with your order.
