Wed Sep 25 02:05:57 UTC 2024: ## Children’s Eyesight Worsening Globally, Pandemic Exacerbates Problem

**London, UK** – A new global analysis warns that children’s eyesight is deteriorating at an alarming rate, with one in three now suffering from short-sightedness, a condition also known as myopia. The study, published in the British Journal of Ophthalmology, found that the prevalence of myopia tripled between 1990 and 2023, reaching 36%.

The researchers point to the COVID-19 pandemic as a contributing factor, with lockdowns leading to increased screen time and decreased outdoor activity.

**Asia Leads the Way**

The study, which analyzed data from over five million children in 50 countries, revealed that East Asia has the highest rates of myopia. A staggering 85% of children in Japan and 73% in South Korea are short-sighted, with over 40% affected in China and Russia. In contrast, Paraguay and Uganda have some of the lowest rates, with myopia affecting only around 1% of children.

**Other Factors at Play**

The research highlights various factors contributing to the rise of myopia. Genetics plays a significant role, with children of short-sighted parents being three times more likely to develop the condition. Early schooling, particularly in places like Singapore and Hong Kong where children start school at age two, also increases the risk.

**Recommendations for Prevention**

To combat the rising prevalence of myopia, eye experts recommend that children spend at least two hours outdoors each day, especially between the ages of seven and nine. While the exact mechanism is not fully understood, outdoor activities seem to have a protective effect.

Parents are also advised to have their children’s eyes checked regularly, particularly between the ages of seven and ten.

**Future Outlook**

The study predicts that by 2050, more than half of teenagers worldwide could be affected by myopia. Girls are expected to have higher rates than boys due to spending less time engaging in outdoor activities.

While the condition cannot be cured, glasses or contact lenses can correct vision. Special lenses, which are becoming popular in Asia, can slow down the progression of myopia, but they are expensive.

The rising prevalence of myopia is a growing concern as it could lead to a surge in eye conditions later in life. The study emphasizes the importance of taking preventive measures to protect children’s vision.
