Darran elaborated that dry eyes may manifest as a burning or gritty sensation, making it uncomfortable for individuals to focus.Additionally, fluctuating vision can occur due to an unstable tear film,which is essential for clear sight.

Digital eye strain refers to a collection of eye-related issues stemming from excessive use of screens - be it smartphones, tablets,or computers.

Darran explained: “Digital eye strain basically refers to a group of eye or vision-related problems essentially due to overuse of digital devices.”

“In order for you to see clearly, the front surface needs to be nice and smooth,” he added, emphasising the importance of maintaining eye moisture.

This condition, sometimes referred to as computer vision syndrome,affects a significant portion of the population as the duration of screen time continues to increase.

Environmental factors also play a crucial role in aggravating DES. Darran highlighted how varying climates can exacerbate symptoms: “In Australia,it’s very dry,while in Malaysia, the air conditioning tends to dry the air out.” Such conditions can further destabilise the tear film on the eye’s surface,exacerbating discomfort.

The symptoms of DES are varied and can significantly impact daily life. Darran outlined common complaints, including eye fatigue,dry eyes,and headaches.

THE

phenomenon of digital eye strain (DES) has emerged as a pressing concern,affecting individuals across all demographics.

With the rise of remote work, online learning,and the pervasive use of smartphones , many are experiencing a range of uncomfortable symptoms linked to prolonged screen exposure.

“Up to probably even 50 per cent of kids are experiencing some form of eye strain,” he observed, attributing this to online learning and increased smartphone use during the pandemic.

“When you don’t blink as much when you’re staring at a screen, the front of the eye dries out.”

Insightful Eye Care Optometrist and Co-founder Darran Yeow offered valuable insights into the nature of DES,its symptoms ,and the environmental factors that exacerbate it.

This lack of blinking can lead to discomfort, blurry vision, and even neck and back pain as users adjust their posture to cope with visual strain.

The Covid-19 pandemic has fundamentally altered work and learning environments, leading to increased reliance on screens.
