In today's world almost all the citizens watch television. Many of them wear spectacles due to this. Some of them who don't like TV said that it is an idiotic box.
Watching television for 1 hour is good but on sametime watching more than 1 hour will not be good for your eyes. Some of them have eye infection due to this. Now a days many of them buy LED, LCD, SMART TVs which is not necessary. So, I conclude that watch TV for less time.
