Reading in Dim Light No Damage Eyes?

During this time the public learned that reading in dimly lit place that can damage the eyes. But what actually happens is not to damage the eyes, but eye stress.

 
This condition is usually often do the kids before bedtime. With only accompanied by dim light or dim his room, the children read the story books, comic books or other books.
As quoted from HowStuffWorks, a study published in the British Medical Journal revealed that reading under low light does not damage the eyes, but it causes eye strain. Because when someone is reading or walking in dim light, the eye will adjust in several ways.

First, the retina of the eye will start producing chemicals that are more sensitive to light, even these chemicals can detect light that is converted into electrical signals and sends signals to the brain.


Second, the iris muscle to relax, causing the opening of the eyes. This allows the eye to collect as much light as possible, so that the retinal nerve cells can adapt to low light to the retina of the eyes can work in low light.

When reading in the dim light, the focus will be more difficult, it makes the eyes have to work hard to separate the words and the eyes become more tense.

If the eyes are working hard for a long time, then the eye will become tired even though many of the muscles used. This condition can lead to some physical effects such as eye pain, itching, headaches, back and neck pain and reduced vision. Also sometimes a person rarely blinking because it is too focused on one object, so the possibility can experience dry eyes and discomfort.

If this condition continues, it will increase eye strain. If symptoms are not reduced, then chances are the person has a fundamental problem such as nearsightedness eye.

Most assume that reading in dim light causes permanent damage, possibly because someone already has the fundamental problem of nearsightedness and coupled with the occurrence of eye strain.

Therefore should be read by using a good light, light not too dim but not too much glare, so the eye does not experience tension. Also try to frequent blinking if it is too focused on an object and look out the window every 15-30 minutes.
