Playing outdoors is very important for children. The analysis of eight research at the University of Cambridge revealed that in each additional hour of time spent outside the house every week, there is a decrease of the possibility of the children to suffer from myopia by two percent.
According to researchers, it could be that it is because the eyes are exposed to natural light and the amount of time spent searching for objects with long distance. A total of more than 10 thousand children and teenagers were involved in this study. These findings were presented at the annual meeting of the American Academy of Ophthalmology in Florida.
Dr. Justin Sherwin and his team of researchers concluded that children with limited sight distance on average spend 3.7 hours less per week outside their houses compared with those with normal sight. Still, he adds, the reason why is not clear.
The researchers are hoping to find a relationship between the children who spend more time outdoors and those who do less activity such as reading, studying, or playing games on the computer. But so far no relationship was found, at least two of the eight research that examines it.
But Dr. Sherwin said they need more accurate data to understand what factors – such as increased visibility, reduced visibility, exposure to ultraviolet light or physical activity – the most important. In addition, there are also other factors to consider.
“Any increase in playing time outside the house should be measured also by exposure to UV radiation exposure and increased risk of skin cancer, cataracts, or other types of cancers.” But on the other hand, continued Dr. Sherwin, “Increased physical activity outside the home can prevent things like diabetes, obesity, lack of vitamin D, and osteoporosis.”
Short distance eye sight is a common condition that causes distant objects appear blurred, while close objects can be seen clearly. Myopia is the medical term for short-distance vision.
The case of long-distance vision impairment is increasingly easy to find in the UK and also the United States in recent years than 30-40 years ago. Nearly 1-2 percent from five to seven parents in the UK experiencing long distance vision problems.
About five million Britons suffer from vision problems and about 200 thousand of them experienced serious sight distance limitations. In some regions of Asia, more than 80 percent of the population suffers from impaired vision.Tagged with: impaired vision, Myopia,
