What Is Myopia? One In Three Kids And Teens Losing Their Sight

A recent study revealed a shocking discovery stating that one in three children and teenagers worldwide is affected by myopia or nearsightedness. 

What is Myopia?

Myopia generally known as nearsightedness, is an eye condition where distant objects appear blurry while close objects can be seen clearly. This condition makes it difficult to see distant objects clearly and often leads to the need for remedial eyewear, such as glasses or contact lenses.

A recent study on myopia, published in the British Journal of Ophthalmology, highlights that myopia is becoming a significant global health issue, affecting one in three children. The study suggests that if this situation continues, over 740 million children worldwide will be affected by myopia by 2050.

Country Status:

The research analyzed data from over five million children across 50 countries on six continents. In this case, Asia turned out to be the most prevalent of myopia. In Japan, about 85% of children are affected, while South Korea reports 73%. 

Other countries, including China and Russia, also have rates exceeding 40%. Some countries like Paraguay and Uganda have much lower rates, around 1%, and the UK, Ireland, and the US report approximately 15%.

From 1990 to 2023, global rates of myopia have tripled, directly affecting 36% of children. This significant increase in myopia cases was observed following pandemic lockdowns when children spent most of their time indoors.

Researchers also indicate that myopia usually develops during primary school years and tends to worsen until the eye growth stabilizes around age 20.

Lockdown Impact:

During the lockdown, people tend to spend most of their time indoors which leads to increased screen time and fewer outdoor activities. The researchers also point to lockdowns as a significant factor in the decline of eyesight among children and teenagers. They stated, "Emerging evidence suggests a potential link between the pandemic and accelerated vision deterioration among young adults."

If the current situation continues, it is predicted by 2050, more than half of the world's teenagers could be affected by myopia. 

The study also indicates that girls and young women may be particularly vulnerable, as they often spend less time outdoors during their school years.

Prevention:

In light of these findings, experts are urging families to limit screen time and encourage outdoor activities to help mitigate the risk of myopia. Increased exposure to natural light and physical activity is believed to play a crucial role in maintaining healthy vision.
