As smart phones affect our vision

What awaits those who spends all day looking at the screen.

Blurred vision

Different types of activities in their own way affect the eyesight. Those who engage in ice fishing, snow blindness can develop - the burn of the cornea by ultraviolet rays reflected from the snow. Welders are injured by electric arc radiation. Observers on ships experiencing hallucinations. Those who often looks at the screen, suffer from blurred vision.

For a while we did not even notice that vision deteriorates. If we see clearly enough, then just add the brightness of the screen. Only it still does not help protect eyesight.

The first sign of decline: you start to squint, looking at the phone. Then, place it closer to the face, increase the font size on the screen. In the end, you give up and buy glasses. They, of course, help once again enjoy reading from the phone without interference. But there is a vicious circle.

We appreciate your vision on how well we see the letters on the phone. And do not think that this phone is undermining our ability to see.

already registeredTransient Smartphone "Blindness" several cases of temporary blindness from the smartphone. If it for some time lost the ability to see with one eye. This problem arises from reading lying on her side in the dark. At the same eye with which you see on the screen is adapted to the light, and the one that closed the pillow - to the darkness. After that, the eye to adjust to the light, "fades". Fortunately, it only lasts a few minutes.

Computer eye syndrome

Typically, these symptoms are referred to him as blurred vision, dryness and a burning sensation in the eyes and headaches. The term is quite vague. The American Association of Optometrists classifies this syndrome any discomfort that people experience when looking at the screen for a long time.

As treatment they offer so-called exercise 20 × 20 × 20. Every 20 minutes to take a break for 20 seconds and look at something, located on you from a distance of 20 feet (six meters). This exercise will help your eyes relax.

However, this syndrome can be attributed not only the voltage from reading fine print or tired of the bright lights.

If the approach is broader and it includes the more general notion of blindness - the inability to detect objects in the real world, especially natural.

For example, few people today are the different types of trees. We just do not pay attention to them. And so many other phenomena in the surrounding world. In this, perhaps, is the main danger of smartphones.

Of course, to completely abandon the smartphones and other devices will not work. But it is possible to reduce their negative impact. For example, use special apps to view. Do not forget to gymnastics for the eyes. And more often hop off the screenBecause the world is beautiful in itself.
