Which is more harmful for eyes LCD or LED?

Both LCD and LED television sets can damage your eyes no matter what you have at home. The backlights provided by the LCD will harm your eyes and the self-illuminating pixels of the LED will harm your eyes. How are you going to change this from happening? You need to be somewhat far from your television set when you watch. Watching too close to the screen might make your eyes more damaged.

Take note that once your eyes are damaged, it is already irreparable. This is just something that you have to deal with for the rest of your life. Take note that some people are recommended to watch TV closer because of nearsightedness or other eye conditions. The best option is to avoid watching too much television.
