How to prepare your child for their first day back at school
Find out how to make the transition as smooth as possible
The amount of time we’re looking at screens is increasing, with Aussies spending more than nine hours each day exposed to smartphones, computers and televisions – that’s more time spent looking at your screen than sleeping!
And, unless you’re willing to forego your weekly hit of Facebook, Netflix and health articles on The Check Up, it’s likely you’re one of the 73% of young people (or maybe just young-at-heart?) affected by eye strain.
We spoke with Kris Jones, an optometrist from nib Eye Care to get the low down on digital eye strain – and how you can fix those pesky and painful computer headaches.
Picture this. You’re at the gym and decide to increase the weight of your bicep curls. After a few reps, your arms are getting shaky; add another few kilos and they’ll start to get sore. Most of us know our limits, but if you keep adding on more and more weight, you’ll eventually fatigue and increase the risk of injuring yourself.
Just like your arms, your eyes are made up of muscles, and when you overwork these muscles, you‘re left with eye strain.
Some of the most common signs you might be experiencing eye strain include:
Kris explains that your smartphone, tablet or desktop emits blue light. Unlike other lights, blue light flickers, giving you a sharper, clearer visual. However, blue light exposure can lead to eye strain, which is why your eyes are likely to strain quicker when you’re staring at your screen, as opposed to looking out a window.
The good news is that with a bit of extra TLC, you can help ease – or completely avoid – the symptoms of eye strain. Here are Kris’s top tips:
Did you know that you should be sitting an arm’s length from your computer? Or, that there are office or occupation lenses for your glasses available to help you see better in the workplace? Kris suggests chatting with your local optometrist about your specific concerns and lifestyle to get personalised tools and advice that can help you set up the ultimate ergonomic workstation.
Ask any avid Instagram user and they’ll tell you that lighting is everything. It’s no different when it comes to your screen. Kris suggests adjusting your screen brightness to suit your surrounds.
“If you’re in a well-lit office, or looking at your phone outside, lighten the brightness of your screen. Similarly, if you’re watching a movie on your tablet in the evening, turn down the brightness, so it’s a darker screen.”
Kris also recommends adding an anti-reflective coating to your prescription glasses to help reduce reflection and glare from both your screen and overhead lights.
“Another tip is to avoid using screens in dark spaces and position your screens so that there are no reflections from windows or overhead lights, as this can heighten the effects of eye strain.”
Every 20 minutes, take a break from your screen and focus on an object at least six metres away for at least 20 seconds.
Kris explains, “Our eyes weren’t designed to focus on computer screens all day, and your body – and brain – will appreciate a regular break. If you’re in an office, try to step away from your desk for five minutes every hour.”
If you suffer from an eye condition, like short-sightedness or long-sightedness, you could be even more likely to experience eye strain, so it’s important to visit your optometrist for an eye exam. Kris recommends that you’re tested at least every two years and more regularly if you notice any problems with your vision.
Whether you use your device for work, rest or play (or all of the above), it’s important to make sure you’re being ‘screen safe’.
