Some studies emphasize that entertainment devices generate radiation, among others affecting the eyes and neural reactions.
Around 1967, General Electric acknowledged to the audience that some of their TVs, due to errors in manufacture, emit more X-rays than usual (talking of quantities from 10 to 100,000 times higher than recommended by the authorities)
If you sit near any form of technological entertainment, there will be no radiation that endangers your eye health. This, however, does not mean it is a good practice.
However, suffering from eyestrain occurs not only when you see up close the screens. Andrew Hogan, president of the Optometric Association of Australia, explained it this way. "When you look at an object for any length of time, your eye muscles are working The more you focus to this object, the more work these muscle are doing. therefore when you see the screen without looking elsewhere, makes your eyes get tired. "
For example, sit at a proper distance depending on the size of your screen and make breaks to post your views on other objects (near and far).
Another common recommendation is to avoid dark rooms where the screen is the only light source. Again this will not damage your eyes directly but it could cause eye fatigue because of having to adapt to these constantly changing colors around you.
Are 3D content harmful?
With the boom of 3D and even movies in this format, it is common to hear that these contents can be harmful to the eye. So far there are no studies that prove it and professionals are quite skeptical that this can be a reality.
However, some people may find it uncomfortable to see content in three dimensions on a screen. This is common in people with mild vision problems (like nearsightedness, astigmatism and strabismus), as their eyes fail to correctly superimpose the images from each eye to give the final image. In these cases they can cause dizziness, nausea and even eye fatigue, so it is best to use this technology with caution, at a proper distance and breaks.
