World Sight Day, celebrated in second week of October each year.This is year it is observed on  October 12th, serves as a global reminder of the importance of vision and the need to address eye health issues. In recent years, an alarming trend has emerged: an increasing number of young people and students are experiencing various eye problems due to excessive screen time, primarily from computers and mobile devices. This article sheds light on the prevalence of eye problems among youth, citing examples of rising cases, and underscores the importance of proactive measures to protect their vision in today's digital age.

The Digital Era's Impact on Youth Eye Health

The digital revolution has transformed the way young people interact with the world. From online learning to social media, entertainment, and work-related tasks, screens have become an integral part of their daily lives. However, the prolonged and often uninterrupted use of screens has given rise to several eye problems among youth, including:

1.     Digital Eye Strain: Symptoms include dry eyes, eye fatigue, headaches, and blurred vision, often referred to as Computer Vision Syndrome (CVS).

2.     Myopia (Nearsightedness): Studies show that the prevalence of myopia is on the rise among children and adolescents. Excessive screen time is a contributing factor.

3.     Blue Light Exposure: Screens emit blue light, which can disrupt sleep patterns and potentially harm the retina over time.

4.     Lack of Outdoor Activities: Reduced outdoor time, especially among students engaged in online classes, can lead to poor eye development and increased risk of myopia.

Examples of Increasing Eye Problems Among Youth

1.     Myopia Epidemic: In countries like China, Singapore, and South Korea, the prevalence of myopia among young students has reached alarming levels. For instance, in some Chinese cities, more than 80% of high school students are myopic.

2.     Increased Screen Time: The COVID-19 pandemic accelerated the shift towards remote learning, causing a significant surge in screen time for students. A study in the United States found that children's screen time doubled during the pandemic.

3.     Strain-Related Symptoms: Reports of digital eye strain and related symptoms have become increasingly common among youth, leading to a growing awareness of the issue.

Protecting Youth Vision

1.     Limit Screen Time: Encourage youth to follow the 20-20-20 rule, which suggests taking a 20-second break every 20 minutes and looking at something 20 feet away to reduce eye strain.

2.     Blue Light Filters: Many devices offer blue light filters or night mode settings that can help reduce blue light exposure during evening screen use.

3.     Outdoor Activities: Promote outdoor activities and regular breaks from screens to support healthy eye development.

4.     Regular Eye Exams: Encourage young people to undergo regular eye examinations to detect and address vision issues early.

5.     Adjust Ergonomics: Ensure proper ergonomics when using computers or mobile devices to minimize strain on the eyes and neck.

On World Sight Day 2023, it is vital to recognize that the digital age has brought about significant changes in the lives of young people, but it has also posed new challenges to their eye health. The increasing prevalence of eye problems among youth should serve as a wake-up call to take proactive measures to protect their vision. By promoting healthy screen habits, encouraging outdoor activities, and ensuring regular eye check-ups, we can help the younger generation enjoy a brighter and clearer future.
