From work meetings and school assignments to streaming, gaming and scrolling through social media, screen time has become an inseparable part of daily life. While digital devices offer convenience and connectivity, prolonged exposure can take a toll on your eyes. In today’s digital-first world, understanding how screens affect eye health and how to protect your vision is more important than ever.
How screen time affects eye health
Staring at a screen for hours without breaks can strain the eye muscles, reduce the blink rate, and affect concentration. One of the primary concerns is exposure to blue light emitted by digital devices, such as smartphones, tablets and computers. While blue light isn’t inherently harmful in small doses, excessive exposure, especially in the evenings, can disrupt sleep patterns and may contribute to digital eye strain.
When your eyes are forced to focus on digital screens for extended periods, they work harder than usual. Over time, this overuse can lead to discomfort and eye issues.
Common symptoms of digital eye strain
If you’re experiencing any of the following symptoms after screen use, you could be dealing with digital eye strain:
- Dry, irritated eyes
- Blurred or double vision
- Headaches
- Neck and shoulder pain
- Difficulty focusing
- Increased sensitivity to light
These symptoms can impact productivity, sleep quality and overall comfort, making it crucial to address the issue before it worsens.
How blue light glasses can help with digital eye strain
One of the most effective ways to combat digital eye strain is by using eyewear with a blue-light coating on its lenses to shield away the harmful blue light emitted by digital screens. Blue light-blocking glasses filter out a portion of this high-energy blue light emitted from screens, helping to reduce glare and visual fatigue.
By limiting blue light exposure, they not only reduce eye strain but can also support healthier sleep cycles, especially for those who use screens late at night. Whether you’re working from home or binge-watching your favourite show, blue light glasses are a simple yet effective solution to protect your eyes without compromising on clarity or comfort.

Easy tips to reduce the impact of screen time on eye health
Here are some easy-to-follow tips which you can follow for good screen habits that can help reduce eye strain:
- Follow the 20-20-20 rule: Every 20 minutes, look at something 20 feet away for at least 20 seconds.
- Adjust screen brightness and contrast: Adjust your screen’s brightness to match your environment to minimise glare.
- Use artificial tears: If your eyes feel dry, eye drops can help keep them lubricated.
- Maintain proper posture: Position your screen at arm’s length and slightly below eye level.
- Limit screen use before bedtime: Reducing exposure to screens an hour before sleep can help regulate your body’s natural sleep rhythm.
Digital devices aren’t going anywhere, but neither should your eye health. If you find yourself glued to screens for hours on end, it’s worth taking steps to protect your vision. From wearing blue light glasses to adopting simple screen hygiene habits, small changes can make a significant difference. After all, your eyes deserve a break, too.
