The screen of your TV (and other devices such as tablets and phones) emits blue light. If you look at it in the dark, it can cause problems.
Some believe, for example, that this. A study by the University of Toledo has shown that blue light causes the formation of toxic molecules in photoreceptor cells of the retina. These molecules can accelerate visual degeneration.
Although the damaging effects of the blue light on the eyes must be further explored, it is widely agreed that thisbecause your body perceives it as daylight. Nighttime TV can disrupt the natural circadian rhythm of your body by reducing the amount of melatonin produced because the body thinks it is daytime. Melatonin is basically a sleep hormone and without it you stay awake.
To save your eyes ̵
Use a blue light filter.
Many new TVs have blue light filters that you can turn on. The filter sets the sound of the light emitted by the screen to a warmer tone, which is better for your eyes and the chemical production for the sleep in your brain.
To turn on the filter, go to menu and select option . Then look for the blue light filter to activate it. If you can not find the setting, you may want to refer to the owner's manual.
If your TV does not have a blue light option, do not worry. You can buy blue light filters that stick to the screen and change the color of the light or block the blue light.
Using a projector
Replacing your TV with a projector may be a good idea. A projector throws its light off a wall or screen while a TV directs the light at you. Projectors thus expose your eyes to less blue light.

If the jury is still out, blue-eye blocking glasses can be helpful. They absorb blue light so that less of it gets into your eyes and you just have to put them on before turning on the TV..
