Band 7+: A growing number of office workers are experiencing 'digital eye strain' due to prolonged screen time, yet many workplaces lack policies to address this issue. What are the primary factors contributing to this problem, and how can employers and governments effectively combat it?

The rise of digital devices, like computers and laptops, in the workplace is widely considered to be beneficial because they are convenient and efficient. However, a growing number of office workers are experiencing “digital eye strain” due to long screen time and little rest, along with the lack of policies to address this problem.

First, it is important to understand thoroughly what “digital eye strain” is. This is a condition in which a person experiences dry and burning eyes, blurry vision, or headaches, and is caused by looking at digital screens, such as phones, computers, and tablets, for an extended period of time. Although it may not seem serious or long-lasting, this issue can negatively impact people’s health and reduce productivity in the workplace.

The most notable factor contributing to this problem is screen habits. Excessive workload can make people blink less frequently, skip necessary rest breaks, and stare at screens for prolonged periods without interruption. When focusing on screens, blink rate can drop by up to 50%, which rapidly dries out the surface of your eyes and leads to fatigue, redness, and blurred vision. Inappropriate office lighting can also worsen strain. Dark lighting can force the eyes to concentrate more, which may lead to irritation. Furthermore, bad posture or short distances from the screen can also put pressure on eye muscles.

It is important for companies to address the problem is a variety of approaches. Foremost, they must implement appropriate breaks so office workers can rest their eyes. Methods such as 20-20-20 (every twenty minutes, look at a distance of about twenty feet for twenty seconds) to relax their eyes have been proven to be effective against eye strain. In addition, workplaces must adjust their lighting depending on daylight, avoiding too dark or too bright environments to reduce strain. Educating workers about correct postures is also necessary in the long-term.

Digital eye strain is a significant issue, but by implementing the right strategies, it can be effectively addressed.
