In the bustling rhythm of our daily lives, we rarely pause to consider the remarkable organs that allow us to experience the world in vibrant color and detail—our eyes. Yet these delicate instruments require consistent care and attention, especially as digital screens increasingly dominate our waking hours.
Dr. Alejandro Oliver, ophthalmologist at Timmins and District Hospital, has noticed a concerning trend in his practice. “I’m seeing patients with digital eye strain at younger ages than ever before,” he explains during our conversation at his clinic. “What used to be primarily an issue for older adults is now affecting teenagers and even children.”
The statistics support his observation. According to recent Canadian vision health surveys, nearly 60% of adults report experiencing symptoms of digital eye strain, while screen time among children has increased by over 50% in the last decade. These numbers paint a clear picture: our collective eye health faces unprecedented challenges in the digital age.
“The human eye wasn’t designed for hours of close-range screen viewing,” Dr. Oliver notes. “But with some simple adjustments to daily habits, most people can significantly reduce strain and protect their vision for years to come.”
The 20-20-20 rule stands as perhaps the most accessible preventative measure. Every 20 minutes, take 20 seconds to look at something 20 feet away. This simple practice, which Dr. Oliver recommends to all his patients, helps relax the focusing muscles in your eyes that tense during prolonged screen time. Setting a quiet timer or using one of the many available apps can help make this habit automatic.
Proper lighting also plays a crucial role in eye health. “Many people work in environments with either excessive glare or insufficient illumination,” Dr. Oliver points out. “The ideal setup includes ambient light that’s roughly half as bright as typically found in office settings, with a focused task light for reading physical documents.” For screens, positioning is equally important—they should sit slightly below eye level at arm’s length to minimize strain.
Nutrition represents another pillar of ocular wellness. “The connection between diet and eye health is stronger than most people realize,” says Dr. Oliver. Foods rich in omega-3 fatty acids (found in fish like salmon and mackerel), lutein and zeaxanthin (abundant in leafy greens), and vitamins C and E (present in citrus fruits and nuts) all contribute to maintaining healthy eyes. While supplements can help, the ophthalmologist emphasizes that “whole foods deliver these nutrients in forms your body can most efficiently use.”
Regular comprehensive eye exams remain the cornerstone of preventative care. The Canadian Association of Optometrists recommends adults have an eye exam every two years, and annually for those over 65 or with existing conditions. “Many serious eye diseases develop without symptoms in their early stages,” Dr. Oliver cautions. “Only professional examination can detect these issues before they cause permanent damage.”
For Timmins residents in particular, Dr. Oliver highlights seasonal considerations. The harsh northern winters bring unique challenges—snow blindness from intense UV reflection can cause painful temporary damage, while dry indoor heating systems often exacerbate dry eye syndrome. “Quality sunglasses with UV protection are essential year-round in our region, not just in summer,” he advises. “And consider using a humidifier during winter months to maintain healthy moisture levels for your eyes.”
The rise in myopia (nearsightedness) among children represents another concern. “Children need regular breaks from close-up activities, whether screens or books,” Dr. Oliver emphasizes. “At least two hours of outdoor time daily has been shown to significantly reduce the risk of myopia progression.” This recommendation aligns with what eye health researchers call the “outdoor effect”—natural light exposure appears to play a protective role in developing visual systems.
Perhaps most importantly, Dr. Oliver stresses the need for awareness of warning signs that warrant immediate attention. Sudden vision changes, flashes of light, floaters, eye pain, or redness should prompt a visit to an eye care professional without delay. “When it comes to your vision, it’s always better to err on the side of caution,” he says. “Many conditions that could lead to vision loss are entirely treatable when caught early.”
As our interview concludes, Dr. Oliver offers a final perspective that frames eye health within the broader context of wellbeing: “Our eyes connect us to the world and to each other. Taking care of them isn’t just about preventing problems—it’s about preserving our ability to fully experience life’s precious moments.”
In a world increasingly mediated through screens, this reminder feels particularly poignant. The gift of sight, so easily taken for granted, deserves our conscious protection through simple daily habits that, when practiced consistently, can help ensure our visual health for decades to come.
