Although computer vision syndrome is particularly troublesome, it does not cause long-term harm, but it can certainly facilitate the onset of other diseases, starting with dry eye syndrome.
Among the treatments that can help the eye, we guarantee:
- Observe a point 10 meters away for at least 20 seconds, approximately every 20 minutes.
- If there is an opportunity to get up at this turn, you can stretch and relax your neck;
- Use a high-resolution screen, excellent as it makes reading on the screen less stressful, thanks to more defined characters and higher contrast.
- Do not forget: the screen should be kept at a distance of 50 or 70 cm from the eye, with its upper edge made the same height as the eyes, in order to keep the head slightly tilted down;
- adjust the screen brightness so that it is slightly higher than the surrounding environment, and the working environment should not be too bright and free from reflections that confuse the vision, which will force the eye to make greater efforts; the use of programs that can make the light emitted by the screens more yellow;
- Keep your shoulders and head back while using your smartphone, bringing its screen closer to your face and not the other way around: this will improve your posture by making a little extra effort for your arms.
