Within just two weeks, we’ve been quarantined to our homes. The new reality has quickly forced significant changes. The unknowns and worry of this global pandemic, the economic and financial uncertainties, new family routines and dynamics at home, and the lack of direct human contact are all new challenges we find ourselves facing.
A type of silver lining is the (new) technologies allowing for real-time connections and virtual meetings with people all around the world. For those who are fortunate to be digitally connected and able to work remotely, the internet, remote access and cloud-based technologies all access to work and resources wherever you are.
It is (too) easy to start checking the news and emails on your mobile from the moment you wake up. Your brain starts processing information and working immediately. Then you move to your laptop or VDU for another days’ work, focusing on the screen, including analysing data, writing content and having virtual meetings. At the same time, you’re switching frequently between your mobile phone or tablet and your VDU screen. And some of you are possibly home-schooling children or helping them with their work which may also include the use of screens and devices.
But the increased screen and device time has caused an increase in other challenges. Eyestrain, headaches, loss of focus, dry irritated eyes, burning eyes, tired eyes, blurred distance vision, neck and shoulder pain are all symptoms that have seemed to increase since the start of COIVD-19 and lockdown. In addition to increased and excessive screen time, those working from home can easily miss out on the daily exercise and sunlight they were experiencing on a normal commute into work. Several patients have also said that it has become too easy to work longer hours with more prolonged time in front of the screen due to the difficulty of ‘switching’ off as home and work are no longer physically separated.
70% of computer users in the UK regularly used to leave work at the end of the day suffering from one or more of these symptoms1. And now that most people are working from home, it’s quite likely that you may even be experiencing one of those symptoms while reading this article.
1 in 5 office workers admitted to making mistakes because of eyestrain1. 5% of workers confessed that eyestrain prevented them from effectively contributing to meetings1. Only 1 in 5 people said they take regular breaks from the screen3.
Computer Vision Syndrome (CVS) is the condition that describes experiencing one or more of the symptoms above. It is caused by a variety of factors that are either internal, including a problem with the focusing of the eyes, an inability for the eyes to work together properly, and people blinking less when concentrating on a computer screen. Other factors are external, including a poorly situated screen with lots of glare from lights or windows, a screen that’s incorrectly positioned for the neck and shoulders, having too little contrast on the screen or an improper brightness setting. All of the symptoms are much more likely to occur if there is a high level of workload and stress, having to perform difficult tasks or if the time spent in front of the screen is too prolonged.
Eyestrain and computer vision syndrome shouldn’t cause permanent damage to the eyesight of adults. Rightly or wrongly, over 50% of employees attribute worsening eyesight to computer use1. It can, however, reduce productivity and employee well-being.
Normally, I would recommend heavy VDU users have a sight test and examination. However, this is not currently possible. Once the restrictions of COVID-19 are lifted, I recommend arranging a VDU specific sight test for anyone who uses screens and devices as the main way of getting work done. In addition to checking the health of the eyes, such tests also assess the need for glasses when using screens, how the eyes work together and the ability to maintain focus for screen-related tasks.
The Optometrist can then give specific, tailored advice to help relieve any symptoms of CVS, improve your performance when using screens and that means you can work more comfortably and effectively.
Until in-person sight tests are possible, the following advice should help to reduce symptoms and minimise the impact of using digital devices and screens.
