Why is short-sightedness increasing in children these days?

Myopia is on the rise. In the UK, the number of children with myopia has doubled in the last 50 years. Globally, it’s projected that by 2050 half of the world’s population will be myopic.

Although myopia – also known as near-sightedness or short-sightedness – can run in families, environmental factors, such as spending too much time indoors have a large influence.

For most people, myopia develops from a mixture of both genetics and environmental factors. But while evidence shows that modern lifestyle factors contribute to myopia, scientists still aren’t entirely sure why.

For instance, research shows that the amount of time a child spends outdoors can play a significant role in their risk of developing myopia.

Not only do most studies show that children who spend more time outdoors are less likely to develop myopia, studies requiring children to spend extra time outdoors during school hours have shown the rate of myopia onset decreased compared with children who didn’t spend additional time outdoors.

But researchers still aren’t quite sure why this is the case. One theory is that the higher levels of light outdoors releases more dopamine into our retinal receptors (the nerves that process light signals in the eye), thus protecting against myopia.

Another suggestion is that the greater amount of physical activity children typically get outdoors prevents myopia. But studies have now shown that this has little effect.

It’s also been suggested that the different patterns and details we see in outdoor versus indoor spaces might explain the increase in myopia.

For example, one study suggests that the abundance of plain features and walls in indoor environments is to blame. This may also be why myopia tends to be more common in urban areas, however, more research is needed to understand this.

Modern lifestyles

Nevertheless, modern lifestyles often require us to spend a lot of our time indoors. For example, children are spending longer in formal education thanks to increases in school leaving age and more people pursuing higher education, which evidence suggests can cause myopia.

Yet what aspects of formalised education are causing increases in myopia is still unknown. Prolonged reading, learning at close distances, time spent indoors and increased screen use might all be to blame.

While one study suggests reading at a distance closer than 25cm may be a risk for developing myopia, reading probably only has a small effect on developing myopia.

The effect of greater screen use on myopia in children also has mixed results – probably because estimating screen use and controlling it in a long-term experiment is difficult. Regardless, further research is needed to understand whether excessive screen use is to blame for higher rates of myopia, and why this is the case.

Given the risk factors for developing myopia, there are also concerns now that stay-at-home orders and home learning during the pandemic may have worsened children’s eyesight.

Although there has been no study yet looking at the effect on children in the UK, early results elsewhere suggest that the pandemic may cause more children to develop myopia – but it’s anticipated the effects will be small. Whether the pandemic will have caused permanent increases in myopia is also yet to be seen.

Currently, the best advice for limiting the risk of developing myopia is to increase time spent outdoors, even by 40 minutes a day.

Mangaluru, Sept 14: Offline classes for grades 8, 9 and 10 will commence in Dakshina Kannada district from September 17 and for grades 6 and 7 from September 20.

Deputy commissioner KV Rajendra chairing an official meeting on Monday said that schools should compulsorily follow Covid-19 guidelines while commencing offline classes. 

“Nearly 99% of teachers and staff in schools in the district have received vaccines. Currently, 261 children are undergoing treatment for Covid-19. Take initiatives for the treatment of children and trace their contacts. Teachers should ensure that all children entering classes are wearing masks and follow social distancing strictly,” the DC said.

He said schools should continue the online classes even after the commencement of offline classes. “Consent letters from parents should be obtained compulsorily before allowing children to attend offline classes. Students from Kerala should stay in hostels or they may continue to attend online classes,” he said.

Schools should provide basic facilities including toilets before the commencement of offline classes. Teachers and staff should undergo Covid-19 tests periodically and ensure that parents of children attending classes have no symptoms of Covid-19, he added.

Though the DC allowed PU colleges to commence offline classes for I PU, the date has not been fixed. DDPU C D Jayanna said that classes will be commenced for I PU as per guidelines soon.

Bengaluru, Sept 21: At least two persons lost their lives and a few others are feared trapped after a major fire broke out following suspected LPG leakage in an apartment at Devera Chikkanahalli, around 20 kilometres from Bengaluru. The blast is said to have occurred in the third floor of Ashrith Apartment. Three nearby flats have also reportedly caught fire.

Fire, emergency department officials and the police are trying to bring the fire under control and rescue those trapped.

There is speculation that a child may have died in the fire, but officials are yet to confirm it. Five persons have been rescued so far. 

Preliminary information suggests that the fire broke out in the top two floors of the five-floor apartment building due to an LPG gas leakage, followed by a blast around 5 pm. The fire has spread to four flats, and officials are trying to prevent it from spreading further. Furniture and other valuables have been gutted in the flames.

Soon after residents heard a huge noise and noticed smoke in the apartment, they ran out from their flats to save themselves. The building has 72 flats. 
People noticed a woman trapped in the fire. She was unable to come out of her flat or jump as there was an iron grill mesh on the window. One witness added that it is not known yet how many are trapped. 

Srinath Joshi, deputy commissioner of police (South-East) said, one person was shifted to hospital and two others are suspected to be trapped inside. More details will be available only after the fire is brought under control, he said.
