Sitting long before the computer does not harm the eyes?

Today, the number of people who regularly use computers, smartphones, tablets . has increased to a dizzying level in just over a decade.Facing this situation, many experts voiced concern about the relatively dangerous health problems that humans may encounter during that exposure, especially with the eyes.

But in fact, is it really that serious?

According to scientists, so far, many proofs prove that from age 10 onwards, our eyes will not be hurt no matter how long we look at any object (of course, face heaven and objects with similar light are exceptions. If at the time before 10 years of age, these behaviors may negatively affect the vision because the nervous system between the eyes and brain is still in the developing phase.

Normally, when reading a piece of paper, light from the surrounding environment will reflect the surface of the paper and go straight into the eye. The retina at the back of the eye when receiving that light starts the process of converting into a signal that the brain can understand. This process is similar to when we look at the TV screen, computer ., just a little bit differently that the light is emitted directly from the screen and not the light through reflection as above.

Some people expressed concern about the type of radiation produced by electronic products, but in reality this is not worrisome. Radiation is a kind of visible light, which is why we can see the screen without reflection. It is located outside the visual spectrum, has low energy levels and is harmless.

Frequent contact with the computer is not a cause of eye damage.

Besides, there are many opinions complaining that sitting in front of the screen makes them feel headache and eye pain. Explaining this, the experts say that when focusing on the screen, our eyes did not properly perform the functions that the Creator gave. Eyes are developed in a major direction to observe on a wide scale rather than regularly looking at things that are too close. Focusing on a close object (here is a computer screen, smartphone, TV .) requires eye muscles to shrink, the convergence of the eyes is very high, which increases the symptoms of eye strain if kept in this condition. for many hours.

According to doctors, this is one of the main causes of headaches. However, the damage is not permanent, it will naturally disappear when you rest properly.

With the question of why eyesight has deteriorated since the beginning of the work associated with computers, experts say this phenomenon may be due to increased frequency of eye activity over time or when they we entered middle age. From the age of 12, the adaptability of the inner lens of the eye decreases and to the age of 40, the eye fatigue will become even clearer. Also, the size of the screen does not affect the eyes if you do not suffer from visual diseases.
