Visual Impairment- types of visual impairment

A person must see clearly, hear clearly, feel sensitively, but in connection with the outside world it is not always possible to combine all this, therefore problems appear. At the moment the most common problem of mankind is visual impairment. According to French ophthalmic company “Horus Pharma”(n.d.), more than half of the world’s population will suffer from myopia, by 2050. This alignment of circumstances makes it much harder to find the reasons for the reduction of vision and the inefficiency of the developed prophylactic.

Unfortunately, the current age of technology has brought not only the benefits and impetus to development. It also contributed to the fact that now most people wear glasses, lenses and suffer from various eye diseases. Phones, computers and various gadgets badly affect human health. This phenomenon adversely affects the organ of vision, reducing the ability to see. This leads to headaches, exhaustion and overstretching of nerve cells. Despite the urgency of the problem, it remains unresolved. A lot of prevention, exercise and a lot of treatment to improve vision, but patient statistics do not change. Globally, it is estimated that approximately 1.3 billion people live with some form of vision impairment. With regards to distance vision, 188.5 million people have mild vision impairment, 217 million have moderate to severe vision impairment, and 36 million people are blind. With regards to near vision, 826 million people live with a near vision impairment.

A considerable number of things have appeared that more or less designed to make life easier for people. For this reason, telephones are the main and most widely used modern technology. All displays of phoned and e-books have an impact on human vision. However, each person has own reason of having poor eyesight. The backlight that mobile phones create is much brighter than e-books have. While viewing a message or visiting Internet pages, people constantly have to concentrate on the phone screen. This fact does not give the opportunity to blink frequently.

As Mutti (2017) said CLEERE researchers found that children who spent more time outdoors had a smaller chance of becoming nearsighted. The researchers also showed that time spent outside is independent from time spent reading, providing evidence against the assumption that less time outside means more time doing close work.

Also, except impact of technologies on eyes, smoking is as bad for eyesight as it is the rest of human’s body. Research showing a link between age-related macular degeneration (AMD) and smoking is now as robust as that between smoking and lung cancer, with the evidence that cigarette smokers are up to four times more likely to be blinded by AMD compared to non-smokers (Reader’s Digest, n.d.)

Although the binding between mental load on eyes and exercises is a popular topic for discussion and researches among the adults, our coevals are not fully aware about this relationship. It might be caused by insufficient prevalence of different methods to keep eyes healthy nowadays.

To improve eyesight and never come back to the stage of visual impairment, it is necessary to take several actions. Firstly, make students to walk and play outside as compulsory order in the school day, as the same as eating and taking a break. Secondly, using items designed specifically to help people with vision loss or other disabilities, including everything from screen readers for blind individuals or screen magnifiers for low-vision computer users, video magnifiers and other devices for reading and writing with low vision, to braille watches and braille printers. Thirdly, giving special eye glasses before computer lessons in order to less effect on eyes.

Human’s eyes are the most valuable things in the life; therefore we have to make an effort to save them by any means.
