3D the term has become a hot topic of discussion we compete, all kinds of 3D products, this came into being. Compared with 3D TV,[link widoczny dla zalogowanych], 3D projectors such expensive products, the price of a pair of 3D glasses to look much cheaper, it also entered the homes of ordinary people more easily, by wearing 3D glasses, we can at home enjoy a variety of 3D games, videos, pictures, visual impact caused by, but you have not thought about for a long time to wear 3D glasses will give us how much harm the human body to bring it?
no doubt, 3D Yanjing let us have a broader, updated visual experience odd,[link widoczny dla zalogowanych], but it also laid on our health risks can not be ignored,[link widoczny dla zalogowanych], we must pay attention to this potential danger, how to solve this 3D technology will be the subject of an important prerequisite for universal one.
no doubt, 3D glasses, we have a broader, updated visual experience odd, but it also laid on our health risks can not be ignored, we must pay attention to this potential danger, how to solve this 3D technology will be the subject of an important prerequisite for universal one.
3D glasses, another hazard is the product quality. As yet there is no uniform standard 3D glasses make the introduction, the market has led to uneven levels of quality 3D glasses, the most expensive only a few dollars can buy, and expensive, you need a few hundred dollars to start,[link widoczny dla zalogowanych], if Disinfection usually do not pay attention when using it, this poor-quality products will result in the consumer's body physiological damage if prolonged use may also leave a movement disorder, awareness of some sequelae, such as dry eyes, body balance decreased, headache and fatigue and other symptoms.
in everyday life we are surrounded by the eye to observe things with a three-dimensional space, and then through the brain produce three-dimensional visual effect, but the reaction is usually very slow,[link widoczny dla zalogowanych], and 3D video frames to be much reaction over our eyes and brain reaction speed, always watch the 3D movie people will find that in your movie watching attentively, without knowing there will be eye fatigue, it is because your eyes for a long time in a state of high speed phenomenon after the overload occurs, particularly short-sighted audience, often in the eye fatigue at the same time there will have a sense of vertigo. A doctor that is not suitable for those suffering from diseases of the eye wear 3D glasses, including glaucoma, refractive errors, as well as the relatively poor ability to regulate visual hyperopia, presbyopia and other patients, who by the 3D glasses will be even greater harm.
Recently, a considerable number of media reported that many consumers to wear 3D glasses in a long time, after things have had varying degrees of physical discomfort, particularly for children and teenagers, psychological and strong novelty serious shortage of self-control makes them indulge in 3D world, unconsciously will produce vision loss, dizziness, blurred vision, eye or muscle twitching involuntarily occur, nausea, cramps, convulsions, loss of consciousness in the direction of disorders and and other symptoms, severe stroke may occur if there are other diseases, 3D glasses for the human dilemma is evident.
why we do so much harm? This may start talking about the principles of 3D glasses: 3D glasses are generally used for viewing 3D movies with the use of, and 3D video by two cameras with different angles taken from the screening when the two sets of images through different polarization After the treatment, projected onto the screen, if, when watching 3D movie, then do not wear 3D glasses to see the fuzzy picture of the two groups would be, and wear the 3D glasses,[link widoczny dla zalogowanych], polarized lens filters for left and right eyes see is different picture, with our articles using glasses to see the true, the brain according to the calculation will produce three-dimensional feel.
3D glasses will
