ekraanivahe

The Estonian word "ekraanivahe" translates to "screen distance" or "display distance" in English. It refers to the optimal or recommended distance between a person's eyes and a digital display screen, such as a computer monitor, television, or smartphone. Maintaining an appropriate screen distance is considered important for visual comfort and health, helping to reduce eye strain, fatigue, and potential long-term vision problems.

Factors influencing the ideal screen distance include the size and resolution of the display, as well as the ambient lighting conditions. For larger screens like televisions, a greater distance is generally recommended to allow the entire screen to be viewed comfortably without excessive head or eye movement. For smaller screens, such as those on smartphones, the distance is naturally closer, but it is still advisable to avoid holding the device too near the eyes for extended periods.

General guidelines often suggest a viewing distance of one to two feet for computer monitors, and a distance roughly 1.5 to 2.5 times the diagonal screen measurement for televisions. The principle behind these recommendations is to ensure that the viewer can see the entire screen without needing to move their eyes or head excessively, and to prevent the screen from occupying too much of the visual field, which can lead to discomfort. Adjusting screen brightness and contrast to match the surrounding environment can also contribute to better visual ergonomics and reduce the perceived need for extreme viewing distances.
