Work on the computer is part of everyday life for many people. A study by the Vision Council shows that 59 percent of regular users of digital devices suffer from symptoms such as dry eyes, headaches and blurred vision. With the right measures for eye health at the computer, you can prevent complaints and protect your eyes.
Optimal workstation design for eye health
For an eye-friendly workstation setup, it is advisable to replace old CRT monitors with modern LED flat-panel displays. These have an anti-reflective surface and prevent distracting flicker that often occurs with outdated cathode-ray tube monitors. Modern operating systems like Windows 11 offer additional settings for an eye-friendly display.
When purchasing a new monitor, you should aim for the highest possible resolution. A high resolution means a smaller pixel pitch and thus a sharper image. Ideal are screens with a pixel pitch of no more than 0.28 mm. Additionally, a large screen with a diagonal of at least 19 inches (approx. 48 cm) is recommended for a ergonomic workstation design.
In addition to screen size and resolution, contrast settings and color temperature also play an important role for eye health. A color scheme in the yellow-green range is easier on the eyes, while blue tones can lead to fatigue more quickly.
Another factor for eye health in the workplace is proper lighting. Light that is too bright, whether from sunlight or harsh indoor lighting, can overload the eyes. The optimal brightness at a computer workstation should be about half as high as is common in most offices. Glare from daylight can be avoided with curtains, blinds, or shutters. Overly bright indoor lighting can be softened by using fewer light sources or replacing them with warm-white LED light.
The ideal distance between the screen and the eyes is 50 to 60 cm. The center of the screen should be about 10 to 15 degrees below eye level to ensure a comfortable head and neck posture. Daylight is generally more comfortable for the eyes than artificial light; however, the monitor should always be aligned parallel to the window to avoid glare and reflections.
Eye health at the computer through proper behavior
To avoid digital overload of the eyes, frequent blinking while working at the computer is very important. By regularly closing your eyelids you moisturize your eyes and prevent dryness and irritation. When staring at a screen you often blink only one third as often as usual and do not fully close your eyelids. This causes the tear film on the eye’s surface to evaporate more quickly and leads to dry eyes.
To avoid dry eyes, the following exercise is recommended:
- Blink 10 times every 20 minutes, closing your eyes slowly as if you were falling asleep.
- Apply the 20-20-20 rule: at least every 20 minutes look at an object that is at least 6 meters away for 20 seconds. This relaxes the focusing muscles in the eye and reduces their fatigue.
- Give your eyes regular breaks: look briefly out the window, let your eyes wander, and blink a few times intentionally.
- Take a screen break at least once every hour, during which you should also avoid looking at your smartphone.
In addition to frequent blinking and breaks, good posture also helps relieve eye strain. Adjust your office chair and desk so that your feet comfortably reach the floor. A ergonomic sitting position with a straight back reduces strain on the shoulders, neck, and spine. An office chair with a backrest that adapts to your natural spinal curvature supports this effectively.
If you need to switch between the screen and paper documents, place the latter on a well-lit holder next to the monitor. This way you avoid frequent shifts of gaze and readjustments of the eyes.
To be able to work healthily and productively at a screen in the long term, you should also pay attention to a balanced diet. Nutrients such as vitamins A, C, and E as well as omega-3 fatty acids play an important role for eye health. These can be found, for example, in carrots, spinach, nuts, and fish. In addition, taking dietary supplements in consultation with a doctor can be useful to compensate for possible deficiencies.
Don’t forget to visit an eye doctor regularly to have your vision checked. Especially with intensive screen work, it is important to detect vision problems early and treat them accordingly.
Conclusion
Digital screen work can place considerable strain on the eyes. To avoid symptoms of eye strain and preserve eye health long term, an optimal workstation layout with eye-friendly lighting, a high-quality monitor, and an ergonomic posture are important. Equally crucial are regular breaks, relaxation exercises, and frequent blinking. If symptoms persist, seek advice from an eye doctor or optician. With the right prevention and individual adjustments, vision can be maintained even with intensive screen work over the long term.
