How does television watching affect the eyes of children?

Answer 1

yes new studies show that it is not good.

Answeryes 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 permanent damage. AnswerNo 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! AnswerDon'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. AnswerNO! 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.

Answer">AnswerBut 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

AnswerIt 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

ANSWER

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.

Answer_with_physics_(kind_of)">Answer with physics (kind of)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 interference. Answer: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. Answer:

Is staring at a candlelight in the dark bad for you?

Answer 2

it does not affect much if you follow some careful steps!as see the TV program from a distancedon't watch for a long time (not more than 6 hours)=have a good day!=

Answer 3

Watching TV in the dark can mess up your eyesight by causing blurry vision. The stress on your eyes from watching TV in the wrong lighting causes blurry vision and tired eyes.
