3d - technology is relatively new, and its impact on the psyche of sight and still poorly understood. But some things are already alarming.
Some visitors celebrated theater after watching dizziness, nausea, eye fatigue and even temporary loss of vision. There are also more sad cases. So after watching the movie "Avatar," the man died. Doctors said that the cause of unhappiness in this case, there was a sharp increase in blood pressure.
Therefore, it is reasonable to parents concerned about the issue,whether it is possible for children 3d?
Let's first silent take a look at what the technology itself.
In Soviet times, there were movie theaters, where you can watch movies with stereo effect. But 3d - is somewhat different technology. The main difference is that a stereo effect is achieved by projecting the image onto both eyes simultaneously, and this makes 3d for each eye separately.
To obtain a three-dimensional image, the human brain needs information from both eyes, because each of them sees the same picture from different angles. Get an image with both eyes, the brain processes the information and allows you to see a general picture in all its depth.
Based on this principle and 3d technology. Images are shown to each eye separately, each side has its own perspective. Frames are replaced with high frequency and for that to see the stereo image in all its splendor, the eyes have to travel very unfunny work.
At the same time, when we consider the real three-dimensional object, our gaze is directed inward, as it were, feeling thing. 3d effect is to create the illusion of depth, and when we look at this illusory three-dimensional object, the eyes take the same position, but other muscles are utilized.
Such a contradiction - a strong pressure on the brain, not to mention the eyes. Now imagine that the child's eyes even more fragile, since it is only at the stage of development. Child and under normal conditions is not able to perceive all the images correctly up to 5 years, when the eye is more or less formed, and these loads can be and it is not able to do.
Specialists Eye Microsurgery directly state that3d movies for children can be dangerous, in particular lead to the development of a pathology of organs.
It is unknown what about this child psychologists say, but the question is,
whether it is possible for children 3dSeriously studied and these specialists.
If we ignore the possible mental health problems and vision, today known exactly are some contraindications, which concern not only children but also adults.
Firstly, 3d movies, do not look to those who have a severe visual impairment, for example, one eye sees much worse than the other, there is strabismus, other eye diseases. Even if these people do not feel discomfort while viewing, there is a risk that they simply do not see the stereo image.
Also raises serious concerns 3d viewing people with unstable mentality. Specialists say that such an image very hard on the cerebral cortex, which may exacerbate the condition of patients in this category.
Oddly enough, it is not recommended 3d and people with diseases of the spine (osteoarthritis, low back pain). This is because such people and so substantially impairing blood flow and blood flow to the visual areas of the brain is insufficient, which in turn leads to strokes.
I think that this applies primarily to adults, but it is worth consideringwhether it is possible for children 3dSuffering from these diseases.
To view a movie format 3d glasses are required, they enable the perception of stereo. Here also seen some problems. Quality sunglasses should not change the degree of illumination image darken it. Experts believe that such a defect can also lead to headaches, eyestrain, nausea and other troubles.
And if you do decide to go for a session, inspect the glasses. Especially meticulously should choose3d glasses for children.
In addition to changes in lighting, you need to pay attention to the integrity of the points. Even small cracks are not allowed. At best, you will not be able to enjoy the surround effects in the worst earn visual disturbances.
In many theaters standard issue glasses of medium size, but there are those where available 3 types of points: male, female and3d glasses for children. This point is to clarify before going to the cinema. After all, the distance between the eyes of the child is much less than that of an adult, which means that it will not just be uncomfortable in such spectacles, but they can also harm him.
Specialists generally advised to have their own glasses, especially3d glasses for children. Firstly, you will be assured of their quality, and secondly, can choose the size that suits you and, thirdly, protect yourself from eye infections, which, anyway, can be transmitted through objects of common use.
If you do not have my glasses, it is reasonable to buy disinfectant wipes, which should be wiped issued in the cinema.
But back to the specific issue:whether it is possible for children 3d. Here experts are unanimous: you can arrange child holiday, but at the same time carrying out a number of conditions.
As already mentioned, carefully choose3d glasses for children. Best of all, if it will be special, small size.
It is better not to drive to the session toddlers who are under 5 years old, most likely you will have to leave in a few minutes after the start of view.
Pay close attention to the condition of the child during the session. If you see that he periodically takes off his glasses, t eyes or hear complaints about the bad state of health, it is better to immediately leave the cinema. Simply remove the points here is not to escape, because without the glasses, the screen will be of poor quality.
If the baby is transferred session, do not rush to carry it again. As mentioned3d movies for children - Serious load primarily on vision. Therefore rare trips can become a real holiday, while overindulgence can harm health.
