In light of reports showing that the average adult spends 3 hours 23 minutes each day, or 50 days a year, looking at their smartphone screen ( Code Computerlove Report , March 2019), Essilor.co.uk is highlighting the risks of Computer Vision Syndrome (CVS) caused by looking at pixelated computer and smartphone screens for long periods. Because screen pixels constantly refresh, eyes are always having to refocus, which causes eye muscles to become tired. In addition, people blink less frequently when staring at a screen, so eyes dry out and vision can become blurred. Other symptoms of CVS include headaches and neck and shoulder pain. To combat the effects of CVS, Essilor advises screen users to:
*follow the 20:20:20 rule – every 20 minutes look at something 20 feet away for 20 seconds;
*take a screen break, go outside and look at objects in different distances and in natural light;
*practise ‘eye yoga’ – look to the left, hold the position, then repeat looking right; look up, hold the position, then repeat looking down. Do these exercises four times, closing your eyes and relaxing in between;
*have regular eye tests; and
*use specialist computer lenses, like Eyezen lenses with DualOptim technology, which are designed to prevent or reduce visual fatigue and can be specified with Eye Protect System to filter blue-violet light.
