💻How to make sure your eyes are screen smart
One in four UK adults are now spending 14 hours or more a day on screens. With such high levels of screen-time it’s important we’re all aware of the impact this can have on our eye health and understand some simple steps we can take to minimise the effects.
Looking at screens won’t permanently damage your eyes; however, it may cause eye strain, headaches, and trigger episodes of visual stress. These reactions to prolonged screen use are commonly known as ‘screen fatigue’ and while symptoms tend to subside after resting your eyes, screen fatigue can be uncomfortable and frustrating.
Extended screen time can also make symptoms of existing eye conditions such as uncorrected myopia (short-sightedness) more pronounced.
Symptoms associated with staring at a screen for long stretches without taking breaks can include:
• Tired eyes.
• Headaches and concentration difficulties.
• Blurred vision.
• Dry eyes.
Minimise the effects
Measure the distance between your face and your device to prevent your eyes working too hard. The 1, 2, 10 method is a good rule of thumb. Keep phone screens 1 foot (about 30 cm) away from your face, laptops and monitors 2 feet away (65cm+) and TVs 10 feet (3.3 metres).
Refresh your eyes by consciously blinking. Your blink rate can fall by as much as 60% when looking at a screen; leaving them prone to dry eye. Stay hydrated by drinking plenty of water too.
For an instant refresh try closing your eyes and rolling your eyeball around behind the closed lid.
Give your eyes a rest by following the 20-20-20 rule. Look away from your screen every twenty minutes, for 20 seconds and focus on something 20 feet away. You should also break up screen time by spending time outdoors. A couple of hours outdoor activity a day can help counter eye strain caused by focusing on close work such as staring at screens or reading.
We hope these tips help prevent issues associated with prolonged time on screens.
