In this satellite century, more and more people are watching television for entertainment and subjective knowledge. But many people have doubts regarding the distance that should be maintained from television while watching, mode of watching and the effects of watching television in darkness, etc. Many people believe that the picture on the television can be seen much clearly in darkness. So they close down all the doors, windows, put off the lights and then watch the television. It may be true also. But by watching television in darkness, eyes get tired quickly. Visionary faults may occur. Actually one can watch the television in dim light also. Eyes would not get tired quickly by watching television with more illumination of light in that room. Also no visionary defects occur. It is good for health to watch television at a distance of two and half meters or seven feet from the television. When we sit for watching television, care should be taken such that the angle between the centre point of television screen and our eyes should be around 10 to 15 degrees so that neck muscles would not undergo unnecessary stress. That’s why it is better to follow guide lines while watching television. Extreme care should be taken in the case of children.
