As our world is growing rapidly towards a new digital revolution in its every step, the attention towards human health on the other hand, is slightly pretermitted. The necessity of working on digital screens raises the physical discomfort of almost every individual. Due to longer working hours on digital devices, a large number of people who work on digital screens complain about eye-strain, which itself has a new scripted term, digital eye strain.
What Is Digital Eye Strain and How It Occurs?
Digital eye strain or computer vision syndrome (CVS) is a repetitive motion injury of eyes often found in people who work on digital screens. Studies have suggested that eye strain and few other visual syndromes occur in 50 to 90 percent of computer users. Our eyes are one of the most sensitive organs that need extensive care. Therefore, it is suggested not to gaze continuously on digital screens such as desktop, laptops, mobile screens, and tablets for more than two hours at a stretch.
When you work on a computer screen, your eyes have to focus and refocus on multiple tabs all the time. The lenses of our eyes move back and forth as reading goes and reacts to each image pixel on screens to send data to brain cells. All these jobs require big efforts for your eye muscles. Unlike papers, digital screens have contrast, flickering, and blue light to worsen the things more. All these problems are enough to cause fatigue, dryness, blurred vision, and eye strain.
Have you ever wondered why the only blue light is harmful when there are several other colours? Very few people are aware of the fact that blue is the prominent dominator in the RGB colour panel of digital screens. Most of the colours are covered with the blue layer, thus blue gives the screen its brightness in order to make every image clearly visible. It is a short-wavelength light associated more with strain than hues of orange and red which have longer wavelengths. Although it creates less harm to eyes than UV rays, it is still a concern that must not go missed. Let’s look at how blue light affects our general health with the help of these below points:
- Disrupts sleep schedule.
- Reduced attention span which leads to difficulties in learning and grasping new things.
- Extreme exposure can damage the retina over a period of time.
- Increases the risk and frequency of headaches.
