Is It Okay To Stare At Lighted Screens In The Dark?


We have all been told at one time or another not to read books or other printed material in the dark. These days most people read and watch images in the dark from the screens of devices like laptops, TV, iPad, iPhone, tablet computers, android phones, computers and other devices with light on their screens. Hand-held devices are held close to the face in the darkness when used sometimes and some people are concerned if this is okay or not, and if there will be long-term effects of this action.
When the eyes are going to be used in a place that is dark or with limited light, the eyes will dilate
more. When you reading from a screen or watching on a screen, there is always a change in the light being emitted from the screen when you actions like flipping, commercial breaks, going back on your screen, going to a new page, changing channels, etc. This results in the eyes working harder to adjust to the constantly changing levels of light being emitted. The eyes muscles are just like other muscles in the body and will get tired from working hard. This will result in headaches, sore eyes, tired eyes, teary eyes, eye fatigue, blurred vision, eyestrain etc.

While there is no research that says that staring at screens in the darkness can damage your eyesight or have negative effects on your sight, it is better to do things more safely for better health over time. Read on your lighted devices or watch TV and other screens with a secondary source of ambient light. The secondary light source may be dim or soft, but this will definitely reduce some of the stress on your eyes by not making the changes in emitted light from your device obvious.

Hand-held computer devices came into popularity in the 2000 with the first iPhone out in 2008 and iPad in 2010. Nobody can tell you about what long-term effects that can occur due to using them in the dark. Who knows what the outcomes may be in the next 10, 15, 20 years or further down in future?

  1. Myles was a 20 year-old man who was brought to the emergency room by the campus police of the college from which he had been suspended several months ago. A professor had called and reported that Myles had walked into his classroom, accused him of taking his tuition money and refused to leave. I was as shocked as a father, Although Myles had much academic success as a teenager, his behavior had become increasingly odd during the past year. He quit seeing his friends and no longer seemed to care about his appearance or social pursuits. He began wearing the same clothes each day and seldom bathed. He lived with several family members but rarely spoke to any of them. When he did talk to them, he said he had found clues that his college was just a front for an organized crime operation. He had been suspended from college because of missing many classes. His sister said that she had often seen him mumbling quietly to himself and at times he seemed to be talking to people who were not there. He would emerge from his room and ask his family to be quiet even when they were not making any noise.I could not stand the shame of my son illness so I decide to consult some of my africa friends at work , and then Tasha introduced me to Dr. Itua who uses her herbal medicines to cure her Hiv and Prostate Cancer after the herbal medicine consumption.
