Children's eyesight is steadily getting worse with 1 successful 3 present short-sighted oregon incapable to spot things successful the region clearly, a planetary investigation suggests.

The researchers accidental Covid lockdowns had a antagonistic interaction connected eyesight arsenic children spent much clip connected screens and little clip outdoors.

Short-sightedness, oregon myopia, is simply a increasing planetary wellness interest which is acceptable to impact millions much children by 2050, the survey warns.

The highest rates are successful Asia - 85% of children successful Japan and 73% successful South Korea are short-sighted with much than 40% affected successful China and Russia.

Paraguay and Uganda, astatine astir 1%, had immoderate of the lowest levels of myopia, with the UK, Ireland and the US each astir 15%.

The study, published successful the British Journal of Ophthalmology, looked astatine probe involving much than 5 cardinal children and teenagers from 50 countries crossed each six continents.

Their number-crunching revealed that short-sightedness tripled betwixt 1990 and 2023 - rising to 36%.

And the summation was "particularly notable" aft the Covid pandemic, the researchers say.

Myopia usually starts during superior schoolhouse years and tends to worsen until the oculus has stopped growing, astatine astir 20 years of age.

There are factors that marque it overmuch much apt - surviving successful East Asia is 1 of those.

Although Asia is expected to person the highest levels compared with each different continents by 2050, with astir 69% short-sighted, processing countries whitethorn besides scope 40%, the researchers say.

Children should walk astatine slightest 2 hours extracurricular each day, peculiarly betwixt the property of 7 and nine, to trim their chances of being short-sighted, accidental UK oculus experts.

It is not wide if it is the beingness of earthy sunlight, the workout taken outdoors oregon the information that children's eyes are focusing connected objects that are further distant that makes the difference.

In Asia, wherever these peculiar lenses are precise popular, glass classrooms which mimic learning outdoors are besides being used.
