is it advisable to watch color tv in the dark?

Answer 1

Nope.....
It is harmful if you to watch TV in the dark. Let's see this from
the eye's view.
In the eye, there is a small opening called the pupil, which controls the
amount of light that enters your eye. This amount is calibrated
according to the lighting of the surroundings. If it is dark, your pupils
widen to let in more light, and vice versa. This helps you in seeing
things in a proper shade, colour, etc, and many other factors which
affect sight. The important thing to remember here is that the pupil
takes some time to adjust to light changes.
Now, when you watch TV in the dark, the amount of light emitted by it is
variable and constantly changing. Your pupils can't adjust to these light
changes as fast as they occur, and that puts a strain on your eyes. If
there is light in the room, this reduces the strain by giving a constant
background against which the pupil can accomodate. Hence, never watch TV
in the dark.
In movie theatres, the same explanation is there. But, can you tell me how
many times do you go to the theatre? not as much as you watch TV. Hence,
no one notices the difference. But, you must have noticed that as soon as
you come out in the bright light of the day from the movie theatre, you'll
be blinded, and it will take soe time before you can see clearly. That
will give you an idea of how much time it takes the eye to adjust to light
differences and why TV shouldn't be watched in the dark.
