Watching television up close is not bad for the eyes because the most recent TV sets, launched from the 90s onwards, no longer emit radiation and therefore do not harm vision.
However, watching television with the light turned off can be harmful to eye health as the pupil ends up having to adapt to different luminosities constantly, which can lead to tired eyes due to excessive stimulation.
It is much more harmful for the eyes to stare at the sun or beams of lights, which are used in clubs and concerts, and can even cause long-term blindness.
What is the ideal distance to watch TV?
The ideal distance to watch TV should be calculated according to the size of the TV screen.
To do this, measure the length of the TV diagonally, from the lower left corner to the upper right corner, and multiply this number by 2.5 and then by 3.5. The range of results will be the ideal distance to watch TV comfortably.
This calculation works for both older and newer televisions, with flat screen, plasma or LED. However, this distance can vary considerably from one person to another and what should be recommended is that it is comfortable to see the entire screen and be able to read the subtitles without any effort.
