About the benefit and harm of reading
The rhythm of a modern life almost does not leave people time for reading. However thirst of knowledge forces us to search for new opportunities for its satisfaction. We read in trains of the underground, buses, we try to receive the information from the screen of the computer. It, certainly, expands borders of our intelligence, but also undermines health of organs of vision.
The Australian researchers came to a conclusion that constant and continuous reading can lead to changes of a cornea and reduction of visual acuity. The reason is in that that during reading eyelids, depending on illumination and a visual angle, create some pressure upon a cornea, that leads to change of the eye form. Physicians advise to make small breaks in reading for prevention of complications, enabling eyes to have a rest.
The same advice can be given to people, whose work is connected to necessity of long contact of eyes with the screen of a computer or a map.
