I’m sure we were all told by our mothers when we were younger to not sit to close to the television and stare at it for too long otherwise we’ll have poor eye sight. This is not the case. Such a myth has been perpetuated through the ages and stems from the time General Electric came out with colored television sets way back in the 1960s’. Because of the amount of radiation that is let off from the screen, federal health officials deemed them highly unsafe. Not wanting their product to trigger great problems for viewers, General Electric stopped selling them.
Dr. Lee Duffner of the American Academy of Opthalmology does not cause any damage to one’s vision. Like staring at anything for too long, watching television can cause one’s ones to hurt as they are so focused on what is on the screen that the eyes get exhausted staying in one focal region for such a vast amount of time. The solution to this is simple. By turning off the television and shutting your eyes to allow them to rest will ease the tension in them and bring them back to a relaxing and natural state. Televisions pose a greater risk to weight gain and influencing somebody’s behavior than eye sight.
This claim that staring at the tube for long periods was also tested by the Lighting Research Center (LRC). The experiment went like this: have volunteers sit in front of the television for an hour while watching an action movie. The type of television in this experiment was a flatscreen television so that could always have the potential to unintentionally manipulate the results. About 50% of the volunteers were to view the film in a room that was brightly lit. After about an hour, they stopped watching and then returned to finish the film, except only this time the room was not lit up. The researchers decided to run a second trial with a different group of subjects with a twist. In this trial, they went from a non lit up room to a brightly lit up one. Throughout this movie watching in different areas of lighting and no lighting, the individuals had to press a button indicating that they were able to respond to visual cues, while the researchers measured electrical brain activity to see if there was a different from first watching the film and then resuming back to it. Blinking of the eyes were also observed for the study’s purpose. Lastly, the individuals of the experiment had to say if they felt the change in lighting had an impact on their eyesight. What the conclusion of this study showed was there was actually less straining and little fatigue of the eyes when the groups were in a brightly lit room, as opposed to watching in a darker room where eyes had a harder time paying attention. Even though it was more difficult to keep watching in the dark, the team of researchers attributed this to people being tired and that no signs were there to indicate that their eyesight was at all affected.
