As the number of people working from home continues to increase, so does the time spent working remotely on a computer screen.
Whether on a desktop, tablet, e-reader, or cell phone, the extra time spent on a computer creates more potential for eye problems. This can lead to the so-called Computer Vision Syndrome or CVS. Improperly placed equipment can cause CFS, resulting in dry eyes, irritation, inattention and an overall negative impact on job performance.
There are several reasons for this. First, it takes a lot of muscle effort to maintain a clear view when working at close range. Within a few hours, the visual system will only experience muscle fatigue. Second, working close by continuously also causes high concentration and can lead to perceptual tunneling, which increases the degree of distraction and shortens the attention span.
Ultimately, everyone who works on a computer suffers from reduced blinks. Blinking produces moisture and is an important part of how the eyes take care of themselves. It regularly blinks about 15 times per minute. However, studies have shown that when using computers and other digital display devices, flickering occurs only 5 to 7 times per minute. Less water on the surface of the eye can cause blurred vision, running water and eye burns.
The following are five ways to combat computer vision syndrome and maintain optimal eye health.
1. Place the visible portion of the screen below the line of sight. Assuming that the ergonomics of the table and chair are good, the computer should be placed slightly downwards.
It is easier to stare down slightly than to look straight or up.
It helps keep the eyelids down and helps reduce the potential for interference from the airflow, especially if the room is air-conditioned. It helps prevent dryness. In addition, the correct screen position can improve the posture of your feet flat on the ground.
2. Eliminate or reduce glare on the screen. Excessive glare can cause mild toxicity or discomfort. It affects a person’s ability to perform their normal work functions. A good test is to place a folder above your head when viewing the work terminal. If it is easier to read than to use a folder, the user may experience discomfort and glare from a disability.
Glare can be reduced by placing a screen on the computer terminal. The anti-reflective coating on the glasses also helps.
3. Keep exposure to blue light to a minimum. As computers become more modern and complex, their ability to be exposed to blue light becomes stronger. This type of light has immediate consequences, including long-term macular health, the part of the eye that deals with 20-20 vision. Blue light can also damage the sleep cycle. Filters and coatings can help reduce blue light exposure.
4. Allow the workstation to enable peripheral vision. Workstations should be constructed to allow for peripheral visual stimulation or continuous eye movement through peripheral vision. Eyesight performs best when exposed to a full range of visual stimuli, not just one type, and no other types can be seen.
Take a break. To best avoid the eye pressure associated with the computer, users should blink their eyes, position the screen in the correct position, and avoid multiple screens and rest. Standing up, walking around, and slight extensions or rotations of the arms, wrists, neck and back help reduce high eye pressure and provide a better work experience.
