IN RECENT years, myopia, commonly known as short-sightedness, has become a growing global concern.

This condition, which affects a person’s ability to see distant objects clearly, is now considered an epidemic that is expected to impact nearly half of the world’s population by 2050.

The rise in myopia cases is closely tied to modern lifestyles, particularly the increased use of screens, reduced outdoor activities, and urban living.

In South Africa, while statistics on myopia are limited, anecdotal evidence suggests the trend mirrors what's happening globally. Understanding the causes, risks, and solutions is vital for parents, educators, and healthcare providers to address this growing issue.

Why is myopia on the rise?

According to global studies, myopia currently affects between 25% and 33% of the world’s population.

The World Health Organisation (WHO) predicts this could rise to 50% by 2050. Lifestyle changes, particularly in urban environments, play a significant role.

Excessive screen time and near-work activities

Children today are spending more time on tasks that require close focus, such as reading, gaming, and using smartphones or tablets. These activities often take place indoors, away from natural light, which is essential for eye health.

Lack of outdoor time

Research shows that spending more than 14 hours a week outdoors reduces the risk of developing myopia by about 30%.
