Working on the screen: How to avoid eye problems in the office
Eye flickering and tired, dry eyes: Hardly anyone who spends several hours working on the computer every day is spared such complaints. Experts explain how such problems can be avoided.
Staring at the screen for hours
More and more people spend most of their working time on the computer. If you sit at your desk all day and stare at the screen, not only do you often experience symptoms such as back pain, but also eye problems. What can you do if your eyes itch and burn? In any case, you should always give your eyes a break. Prevention is also important. The TÜV Rheinland explains in a message how to avoid such complaints.
Treat your eyes to a break
One reason for complaints such as burning or itchy eyes, foreign body sensation and increased sensitivity to light is that the blinking of the eyes is too rare.
"This can be remedied by conscious pauses in vision, in which the gaze is directed into the distance and a regular blink of the eye ensures a good distribution of the tear film on the eye," explained Dr. Wiete Schramm, occupational physician at TÜV Rheinland.
Other experts advise regular relaxation. So it helps to apply an eye pressure every two hours.
To do this, the eyes are closed and the elbows are supported on the desk. Then place the palms of your hands over your eyes, with the ball of your hand resting on the bone under your eyes. Then apply light pressure on the eyes for a few minutes.
Declining tear production
Since the described eye complaints, in addition to a decreasing tear production in old age or internal illnesses, such as diabetes, can also be caused by constant drafts due to air conditioning or the blower in the car, care should be taken that the air flow is not directed directly at the face and eyes .
“The right lighting at the workplace is important for good vision. The combination of direct and indirect light that is reflected from the ceiling or the walls has proven its worth, ”writes TÜV Rheinland.
Proper lighting in the workplace
According to the experts, the illuminance at the VDU workstation should be 500 lux, in the surrounding area at least 300 lux. As visual performance deteriorates with age, older workers need a higher illuminance. 750 to 1000 lux can be useful here to enable fatigue-free reading.
We also recommend individual workplace luminaires that allow the lighting to be adapted to personal needs.
Avoiding reflections on bright, smooth, shiny or reflective surfaces is just as important for relaxed vision. Matt, non-reflective surfaces for office furniture and the choice of appropriate wall colors reduce the stress.
“The use of different colors of light in a room is hard on the eyes. Neutral white or daylight white light is best suited for working on the screen. Warm white light with its higher proportion of red and yellow tones has a relaxing effect and is popular for living spaces, ”says Werner Lüth, Head of Occupational Safety at TÜV Rheinland. (ad)
