Our lives these days are dominated by screens. Whether it's scrolling through social media, binge-watching Netflix, or constantly checking emails on our phones, we're spending more and more time glued to digital devices. And it's not just us - our kids are growing up in a world where screens are the norm, not the exception.
The truth is, this rise in screen time has some serious implications. It can lead to everything from eye strain and headaches to disrupted sleep patterns and even addiction. Many parents are struggling to find the right balance between letting kids enjoy the benefits of technology and protecting them from the potential downsides.
But here's the thing - we can't ignore the fact that digital devices are here to stay. They're a fundamental part of our lives, both at work and at home. Read on as we take a deeper look at digital screens, their impact on our eyes, and some things we can do to reduce the risk of developing eye health problems.
The Science Behind How Screens Affect Eye Health
The science behind screen use and eye strain is fascinating, and it's important for everyone to understand the potential risks.
When staring at screens, eyes must work harder than usual. This is because the eyes need to focus and move more when looking at screens. In addition, screens emit blue light. Vibrating within the 380 to 500 nanometer range, blue light has the shortest wavelength and highest energy.
With our eyes working hard to look at screens, combined with close-up exposure to blue light, prolonged screen usage can contribute to a range of eye health issues.
One of the most common conditions is called digital eye strain, which includes symptoms like dry eyes, blurred vision, and headaches. This is largely due to the fact that we blink less frequently when staring at a screen, which can cause our eyes to become fatigued more quickly. Blinking less also means that extended periods of screen time can also cause dry and irritated eyes.
The blue light emitted by many digital devices has also been linked to disruptions in our natural sleep-wake cycles. Exposure to blue light in the evenings can suppress melatonin production, making it harder to fall and stay asleep. Lack of quality sleep can then exacerbate eye strain and other vision problems.
While not linked directly to screen time, studies have also found that children who spend more time indoors are more likely to develop nearsightedness (myopia) - Kids who are indoors are typically on screens.
Simple Tips to Protect Your Eyes from Too Much Screen Time
While the science is clear, that doesn't mean we have to swear off screens entirely. There’s a few things you can do to care for your eyes while using digital devices.
Be mindful of your screen time - Set limits and take regular breaks to give your eyes a rest. For children, set boundaries around screen time allowances and stick to them. You should also try to model healthy tech habits in front of your kids, put your phone down during meal times and join them on screen-free activities such as a walk outdoors or a board game.
Follow the 20-20-20 rule - Every 20 minutes, look at something 20 feet away for 20 seconds. Encourage children to do the same.
Adjust your screen brightness and contrast - Reduce the brightness to a comfortable level and increase the contrast so text is easier to read.
