Tips for Maintaining Optimal Eye Health in the Digital Age

In today’s digital-driven world, our eyes are constantly working overtime. Whether you're answering emails, binge-watching your favorite shows, or scrolling through social media, screens have become an unavoidable part of daily life. But all that screen time can take a toll on your eyes, leading to discomfort, dryness, and even long-term vision problems. At Lum Optometry, we’re here to help you maintain healthy vision without having to sacrifice your digital lifestyle.

Follow the 20-20-20 Rule

One of the easiest ways to combat digital eye strain is by using the 20-20-20 rule. Every 20 minutes, take a 20-second break to look at something at least 20 feet away. This simple habit helps reduce eye fatigue and gives your focusing muscles a much-needed rest.

Blink More (Yes, Really!)

It sounds simple, but when we stare at screens, we tend to blink less—sometimes up to 50% less than normal. This can lead to dry, irritated eyes. Make a conscious effort to blink fully and frequently to keep your eyes naturally lubricated. If you still experience dryness, artificial tears can help provide relief.

Adjust Your Screen Settings

Your screen’s brightness, contrast, and text size can all impact eye strain. A good rule of thumb is to keep your screen brightness similar to the surrounding light. If your screen is much brighter or dimmer than your environment, your eyes have to work harder to adjust. Enlarging text size can also reduce strain, especially for prolonged reading.

Mind Your Distance and Posture

Sitting too close to your screen can lead to discomfort. Ideally, your screen should be about an arm’s length away, with the top of the monitor at or just below eye level. Slouching can also contribute to tension headaches and neck strain, so maintaining good posture while working can go a long way in preventing discomfort.

Use Blue Light Filters

Exposure to blue light from screens can interfere with sleep patterns and contribute to eye strain. Many devices now offer built-in blue light filters, or you can invest in blue light-blocking glasses. If you work late into the evening, reducing blue light exposure a few hours before bed may improve your sleep quality.

Stay Hydrated

Your eyes need proper hydration and nutrition to stay healthy. Drinking plenty of water throughout the day helps prevent dryness, while foods rich in omega-3 fatty acids, vitamin C, and lutein (such as salmon, leafy greens, and citrus fruits) can support long-term eye health.

Schedule Regular Eye Exams

Even if your vision feels fine, routine eye exams are essential. Digital eye strain can sometimes mask underlying issues, such as uncorrected vision problems or early signs of eye conditions. Dr. Lum uses advanced diagnostic technology to assess your eye health and ensure you’re seeing as clearly and comfortably as possible.

Protect Your Vision in Today’s Modern World

With screens being a permanent part of modern life, prioritizing your eye health is more important than ever. Small adjustments to your daily habits can make a big difference in how your eyes feel and function.
