The intensity of staring at Andina's laptop screen has now diminished. This was in stark contrast when he was still working full-time on a youth-based social news site three months ago. He can spend up to 12 hours in front of the laptop. "From morning to evening, continue to continue again usually until dawn," said Andina.
In addition to work, Andina also continued her master's degree at one of Yogyakarta's public universities. No wonder he had to spend a lot of time in front of a laptop to work plus doing his college assignments.
"In the past when I was young, when I was too close to watching TV, I was sure to get angry with my mother. He said, "Back or you can be blind!" Uh, now I can spend hours on end in front of the laptop screen. And okay, "said the woman who was familiarly called Andin.
As a child, stories about parents' nagging to not watch TV from close range may also be experienced as a child. But now, in line with Andin's story, maybe most of us always spend time in front of a 'glowing screen' from a distance that is definitely not approved by mother.
The question that might be born is, do the hours we spend can affect vision? Is the fear appeal approach from the mother right, and not the message blank like advice: "Do not go out after sunset, the kidnapped will be kidnapped?"
A study published by Scientific American can make you start thinking you have to control the habit of staring at a laptop, computer, or gadget screen with a continuous glowing screen. This research might show, your mother's nagging when we watch TV too closely may have a point.
With conditions that continue to look at the screen, our eyes have the potential to experience eye strains. Tired may look not so creepy. The creepy finding is that the eye strain can increase the risk of glaucoma.
Glaucoma is a type of vision disorder characterized by damage to the optic nerve which is usually caused by pressure in the eye. If you have ever seen a circle of shadows around a light, or a narrowing vision that eventually cannot see the object at all, then glaucoma is infected and you need an immediate examination.
For those of us who pay less attention to the wonders of one of our five senses, we may not be able to respond to a highly complex and highly adaptive visual or visual system. The system can change focus to see objects, both near and far. In addition, the visual system can also change when looking at conditions of light or dark environments.
When our eyes are forced to watch the screen for hours, the conditions caught by the visual system are only minimal variations. "Our eyes are most" happy "assigned to enjoy a varied focus distance, with a variety of parallel light sources that are correct. The use of computers or laptops clearly does not provide these things," said Dr. Jeffrey Anshel, O.D., author of Visual Ergonomics in the Workplace.
Tension of the eyes, for the use of a laptop or computer, there are several causes. First, the eye muscles are forced to work continuously. When looking at the screen, two sets of eye muscles will work together so that our focus on the object can be seen clearly. Like body muscles, continuous use of the eyes can certainly create a tired atmosphere. If you don't believe, have you had a vision experience to be blurred when you look away from the screen? This happened because of the spasm of the ciliary muscles. Our focus, which was previously locked on a laptop or computer screen, then temporarily loses sight.
Second, have you ever felt itchy in the eyes after undergoing a long session in front of a laptop or computer screen? The itching causes the desire to rub your eyes. Itching in the eyes is caused by dry eyes due to rarely winking.
Normal flashing intensity is 12-15 times per minute. But when using a computer, the eye tends to blink less frequently. At worst around 4-5 blinks per minute. Why can the intensity of blinking eyes be rare when looking at the screen? The eyes usually "jump around" on the screen depending on what object we see. This pattern is called saccade. Whereas when it blinks too often, it actually interferes with the pattern and decreases productivity due to decreased concentration.
Another reason that can cause the eye to experience eye strain due to too long staring at the laptop or computer is the light settings on the screen. Arrange as best you can and make sure the light doesn't make your eyes feel stressed by its brightness. "Simple, let's just say you see a light bulb for hours. "The LCD screen of your gadget is almost all illuminated by a rough lamp in your eyes from the very beginning you operate it," said Dr. Anshel.
I have been working on computers for close to 25 years now. I sit in front of four screens every day and I have had no ill effects from it. I think the fact that newer monitors have less of a refresh rate issue is probably a good thing.
With old CRT monitors the refresh rate could cause a rolling or flickering that was hard for some people to see, but it was there none the less. It would constantly cause your eyes to focus and refocus.
The advent of LCD's and LED's has made that much less of an issue. While not totally clear the readability of today's monitors puts much less stress on your eyes and the muscles that control them.
As I said, I sit in front of a computer every day for close to 8 hours. I also visit the eye doctor every year and I have had perfect vision since I was a kid. Everyone else in my family wears glasses, but I am over 40 years old and have never needed glasses.
I think that speaks for itself as to how much screen time can impact your eyesight.
I think the older computers were an issue but today's modern LCD screens seem to be kinder on the eyes. If you spend 12 hours a day behind the screen then maybe over time your eye sight may weaken and need glasses. The glare is not an issue and I think like most older people we will end up with glasses eventually ,but go blind no.
