Digital devices have become an increasingly important part of our day to day lives. Whether it be computers, tablets, smartphones and other electronic devices, these all contribute to the eye becoming tired, resulting in digital eye strain, also known as “computer vision syndrome”
What is computer vision syndrome and what causes it?
Computer vision syndrome – is a group of eye and vision symptoms that can develop from extended periods of viewing digital devices.
Working at computer screens, our eyes typically have to work harder, as they prefer to focus on objects further than 6 metres away. In conjunction with this, smaller devices are also becoming common as people spend more and more time on mobile devices.
Often, devices also throw off a blue light or the glare effects our eyes, resulting in us blinking far less on digital devices that the normal 15 times in a minute.
All of this combined, can lead to dry, red and scratchy eyes
The combination of these unique characteristics and our eyes having to work harder can often lead to difficulty. The extent to which people experience visual symptoms often depends on the level of their visual abilities and the amount of time looking at a digital screen.
The muscles which control eye movements and focusing are typically relaxed when we look at objects in the distance 4 or six metres away).
With extended period of focusing on screens, the eyes, like any muscle in our body can get tired and fatigue. It is important that you look up from the screen and take the time to have a number of breaks.
