London, Dec 28, 2017: Worried that your kid’s eyesight might deteriorate because of endless hours spent on smartphones, gaming consoles, computers and tablets? Take heart, spending just two hours a day outdoors, playing any sport in the sunlight, might help, experts suggest.

Myopia — also known as nearsightedness and shortsightedness — is a condition of the eye where the light that enters the eye does not directly focus on the retina, but in front of it.

 This causes the image that one sees — when looking at a distant object — to be out of focus. It does not affect focus when looking at a close object.

According to experts, lack of natural light is the key behind the condition.

“The main factor seems to be a lack of exposure to direct sunlight, because children who study a lot and who use computers or smartphones or tablet computers a lot have less opportunity to run around outside and are less exposed to sunshine,” Annegret Dahlmann-Noor, consultant ophthalmologist at Moorfields Eye Hospital in London, was quoted as saying to BBC Health.

While stopping or limiting screen time use may be a big task for parents, the best thing to do, say the experts, is to get children playing outside as much as possible.

“We know that myopia or short-sightedness is becoming more common,” Chris Hammond, professor at King’s College London, was quoted as saying to BBC Health.

“Protective of myopia development is time outdoors — sport and leisure outdoors are protective of eyesight,” Hammond said.

“Probably on average across the week and the weekend, two hours a day outdoors is protective of becoming short-sighted in children,” he noted.

Further, a diet rich in omega-3 essential fatty acids, and vitamins A, C and E and nutrients are good for the back of the eye.

Regular annual eye checks can also help, experts suggested. (IANS)

Nose of Kids Hold Clues to Serious Lung Infections

Experts say this breaks with traditional thinking that symptoms predict whether either a virus or bacteria is causing the illness and could impact a decision of whether or not to use antibiotics

Tiny organisms in a child’s nose could offer clues to improving the diagnosis and treatment of severe lung infections, a new study suggests.

The study found that the composition of the microbiome — bacteria and viruses found in vast numbers in the body — was altered in the noses of children with respiratory infections, compared with his healthy peers.

This difference predicted how much time children had to spend in hospital and helped spot those likely to recover naturally, potentially reducing the need for antibiotics, said researchers from the University of Edinburgh.

“Our findings show, for the first time, the total microbial community in the respiratory tract — rather than a single virus or a bacteria — is a vital indicator of respiratory health. This could impact how doctors diagnose LRTIs and use precious antibiotics to fight infections,” said lead author Debby Bogaert, Professor at the varsity.

Lower respiratory tract infections (LRTIs), including pneumonia and bronchiolitis, are a leading cause of death. Symptoms include, shortness of breath, weakness and fever.

It was found that the microbiome in the back of the nose and throat was related to that seen in the lungs, making it easier to understand and diagnose infections.

For the study, published in The Lancet Respiratory Medicine, the researchers studied more than 150 children under the age of six, hospitalised with LRTI. They compared them with 300 healthy children.

Children with LRTI had a different microbiome profile — including the types and amounts of individual viral and bacterial organisms — compared with the healthy children.

These profiles could identify 92 per cent of children as being healthy or ill when combined with factors like the child’s age. This was true no matter what symptoms the child had.
