The main threat scientists see in technology and especially in mobile phones
Scientists have made a sensational discovery and cited three main reasons why people have bad eyesight. So, the main factor of vision loss is not heredity, and the fact that we ourselves spoil.
The researchers caution there are three things that negatively affect vision, but to him we are exposed constantly. The main threat scientists see in technology and especially in mobile phones, as they pose harmful to the eyes light. In addition, a person focuses on one point, which forgets to blink and the eyes not getting enough moisture.
Another threat to the vision is the ultraviolet light and its effects a person is exposed to regularly. On Sunny days wear sunglasses with special protection, marked with UV 400 is able to filter out harmful rays and protect eyes from exposure to them. Direct sunlight can cause thermal burns to the retina of the eye that are impossible to feel because the retina has no pain receptors.
Equally important mistake is that many people ignore the existing difficulties with his eyesight, but in the long term, this can provoke an even more negative effect.
Also, experts suggest that women face a higher risk of vision problems.
“Most people don’t know that two-thirds of people who have lost vision are women,” – says in his interview with Assumpta Madu, an ophthalmologist from Montefiore Medical center in new York.
According to scientists, there are a number of reasons. First, glaucoma which can cause blindness, more common in women. Second, some experts connect this fact with the sex hormones – estrogen, the development of which women almost completely stopped with the onset of menopause. Thirdly, the cause of many eye diseases is poor hygiene wear and care for contact lenses. According to statistics, two-thirds of contact lens wearers is women.
Recall that several ways, allowing you to navigate in a relatively dark room.
As reported by the portal “Znayu”, an international group of scientists from the University of Michigan conducted a series of studies, which found that seaweed can identify a substance capable of coping with blindness, both with acquired and innate.
Also “Znayu” wrote scientists from the University of St. Andrews, UK, have created ultra-thin flexible film capable of emitting laser light. It is based on organic semiconductors, and once installed on the eye it increases the possibilities of human vision.
