yes new studies show that it is not good.
yes it makes your eyes strain to see, which is probably why most
people get tired while watching tv, the pupil in the eye is
constantly adjusting in size to the different levels of light, so
it could cause eye fatigue. That is, it makes your eyes tired and
could make it temporarily harder to focus. It's not likely to cause
No it isn't. A television is a cathrode ray tube with is in effect
shooting light onto pixels. Therefore when you watch tv in the dark
you are basically watching a light. Having an alternate light
source in the room will make no difference whatsoever to your eyes,
except if that light source is reflecting off the glass TV screen
which would cause a glare. If this happens then your eyes will
really strain because they are trying to adjust to see the light
from the CRT. So, having another light on when watching TV could
actually hurt your eyes!
Don't watch TV in the dark! How many times have we heard that? The
truth in the statement lies in understanding contrast ratios. The
eye can adapt to an very wide range of light levels, but it can
only adapt to one light level at one time. When one looks at a
bright computer monitor on a dark background the eye doesn't know
whether to adapt to the bright monitor or the dark background. When
this happens hour after hour, day after day, fatigue sets in. The
same thing can happen when looking at a brightly lit sheet of white
paper in a dark room. To lessen eyestrain: lower the brightness on
the monitor; increase the light in the surrounding area; or both.
Just the opposite problem can occur when one places a computer
monitor in front of a window. The bright daylight surrounding the
screen makes it difficult to see what is on the screen. It is best
to place the monitor perpendicular to the window to minimize high
contrast and reflections on the screen.
NO! Watching T.V. in the dark is not bad on the eyes. Setting to
close to the T.V. is not bad on the eyes.
ophthalmology facts are available on the related links below
But I for one do not believe them, a newer study by Sciencedaily
came up with a different result.
Have a look at their report on he related link below
It is a myth that watching TV in the dark is bad for the eyes with
no scientific basis. The eye is able to view varying degrees of
light intensity and colours due to the presence of rod and cone
cells present within the retina of the eyeball. Rod cells are
responsible for night vision and cone cells are responsible for
more detailed, trichromatic vision. Utilising a combination of
these cells will not damage the eye. The myth is linked to the fact
that reading in the dark is bad for your eyesight. This is indeed
fact due, to the fact that most people require the straining of
their eyes in order to make out characters in a book. Rod cells are
not particulary good at viewing objects in detail. Any prolonged
straining of the eyes can be damaging. Watching tv in the dark at
the correct distance is not damaging. Don't you think the
popularity of cinemas would have rapidly decreased otherwise?
Please note that prolonged viewing of any single object CAN cause
eye fatigue/strain, which once again can be damaging to the eye;
this should not be confused with the act of watching TV in the
dark. Remaining a focus on a fixed point for very long periods of
time, such as a screen can be damaging, in light or dark. Sitting
close to a screen is NOT recommended, because the light intensity
is far greater at short distances. If your eyes feel discomfort,
have a break. Source:Prof. Simon King E
The eyes are not hurt by watching TV in the dark. If you watch a
lot of TV the contrast difference may cause some eye strain, but this only causes eye fatigue
which really isn't all that bad for the eyes. The eyes are more
durable than that.
If you look at those motion pictures as a source of light, then you
can picture having some light in the room can cancel out some of
the lights sending from the TV through destructive interference.
However, constructive interference can also occur which can amplify
the color. So I don't really know whether constructive or
destructive predominates (probably has something to do with the
geometry of the light source and the TV). One thing for sure, with
no lights in the room, the colors are truer since there's no
Millions of people who watch movies in dark theaters around the
country dont seem to complain out the lights being out while
watching their flick.
Is staring at a candlelight in the dark bad for you?
