Computer Vision Syndrome or CVS is a name given to eye problems that are caused by prolonged computer use. When people use computers, tablets or mobile phones their eyes are required to converge closely and keep focus for long periods of time. Eye problems are becoming more and more common due to the increase in digital usage in our world.

Jacquie Gattegno, a Smart Vision Optometrist at Eyes InDesign Bondi, discusses the symptoms of CVS and how to manage problems occurring from digital eye strain as well as how to reduce their effects.

There are signs and symptoms to look out for to know if it’s CVS or not. The symptoms of CVS or digital eye strain include; tired eyes, dry eyes, headaches, glare sensitivity, blurred vision, double vision, eye twitching or excessive tiredness towards the end of the day. If a person suffers from any of these symptoms, it is possible that they could potentially have Computer Vision Syndrome.

“CVS or Computer Vision Syndrome has become one of the most common workplace complaints but it is not exclusive to adults,” says Jacquie. There are millions of children and teens who spend hours in front of a computer everyday. This puts stress on their eyes and can affect normal vision development. If these problems are not corrected in younger people, it has been shown to cause shortsightedness or myopia.

There are ways to treat or control Computer Vision Syndrome. Firstly, a Smart Vision Optometry comprehensive vision skills assessment needs to be performed so that a personal wellness treatment program can be designed for them. Depending on the results of their examination, their Smart Vision Optometrist may prescribe them specific computer glasses customised for where their visual system is at and which will help their eyes focus on the screen more comfortably. “Studies have shown that having the correct computer glasses increases productivity and accuracy,” says Jacquie. It is also recommended to have an anti-reflective coating on their computer glasses as it reduces reflections on the front and the back of their glasses, which causes glare and can make it difficult for their eyes to focus.

Besides wearing the correct computer glasses, there are a few more recommendations they can adopt to reduce the effects of CVS. Follow the ’20-20-20 rule’ which states that every 20 minutes they should spend 20 seconds looking at something that is 20 feet (6 metres) away. It is also important to keep blinking as this helps to wash their eyes with tears naturally. The physical position of their computer as well as their own physical position is also important. The computer or laptop should be at least 40-50 centimetres away from the eyes, this is about an arms length away. The person should adjust their screen so that they look slightly downwards at it. It is also important to adjust the brightness levels to a level that is comfortable. The lighting in the surroundings should be correct, direct lighting overhead should be kept to a minimum. Make sure the desk lamp is shining on the desk and not onto the screen. Try and keep the window light off to the side instead of in front or behind as this will help reduce the reflective glare on the screen. It is also important to make sure that posture is correct while sitting by your computer. It is said that for every two centimetres forward a person leans, there are 14 kilograms weighing on their neck!

Finally and perhaps the most important step is for the person to book a session with a Smart Vision Optometrist to have a comprehensive vision skills assessment as this will enable a unique vision wellness treatment to be planned for them.

Behavioural optometrists like Jacqueline Gattegno of Eyes in Design Bondi are experiencing the rise of CVS, or digital eye strain as it is sometimes called, first hand. Her branch of optometry involves further study that helps her to look at how people use their eyes, the visual skills they need to develop, and the therapies they may need in order to use their eyes for the tasks that make up a regular day. 

“The most well-known application for behavioural optometry is developmental optometry, where the way children’s visual skills are developing is evaluated, and any issues that may be holding back their schoolwork are addressed,” she says. “But now, increasing numbers of adults are in need of interventions, and many of them are not aware of behavioural optometry as an option. With Computer Vision Syndrome on the rise, this needs to change.”

CVS: Prevalence, Causes, and Symptoms

Depending on which studies one reads, anything from 64 to 90 percent of computer users experience the effects of Computer Vision Syndrome. Curing it is easy. Remove the computer and the problem is solved. Unfortunately, life isn’t that simple. 

For many, the business of making a living is tied to long hours of computer use, and it doesn’t stop there. Staying in touch with friends and family, transacting personal business, and keeping up with the news could all mean even more screen time over and above the time they spend looking at screens during a standard work day. 

The average Australian, regardless of occupation, spends 5.5 hours a day in front of a screen – and that’s enough time to place them at risk of CVS. Additional factors contribute: workplace ergonomics can be an issue, as can age (users over 40 are more prone to CVS), or the presence of pre-existing vision problems.

The symptoms of CVS include tired, sore eyes, headaches, dry eyes, blurred vision, double vision, sensitivity to glare, twitching eyes, and neck and shoulder pain. They’re all linked to the demands that is unconsciously place on the eyes when viewing screens for long periods. 

Evidence shows that people blink less than they ought to when looking at screens. The muscles of the eye are also forced to concentrate on the nearby screen for extended periods instead of frequently working to change focus from near to far to mid-distance as they would in the natural context for which they were evolved. Glare, particularly blue light glare, is also a factor, as well as the rapid flickering of screens owing to their redraw and refresh process. Then there are pixels – the blurring of edges they cause may seem imperceptible, but the eyes do pick it up and have to work hard to compensate for it. 

Add existing vision issues, glasses that aren’t well-designed to work at screen viewing distance, poor posture, and environmental issues like incorrect lighting or airflows that dry out the eyes into the equation and people have a challenge that their eyes simply can’t cope with comfortably. And although Computer Vision Syndrome symptoms are reversible, many experts are concerned that it may be linked to the worldwide increase in myopia (short-sightedness). 

How Behavioural Optometry Helps

With so many factors playing a role in causing Computer Vision Syndrome, individual assessments and interventions are often required, but there are a few basics we can try observing on our own, says Jacqueline. 

“The 20-20-20 rule is worth trying. After 20 minutes of screentime, spend 20 minutes looking at something 20 feet away. You should also be aware of blinking, and blink often. It can be hard to develop these habits, but they will help in reducing strain on the eyes. Computer monitors should be 40 to 50 centimetres away from your eyes and you should be looking downward slightly when viewing them. Lightning shouldn’t be directly overhead, behind, or in front of you or too bright. Good posture also helps.” 

However, these habits, good as they are, might not be enough to solve the problem. “People may need computer glasses,” says Jacqueline. “They should be made for the screen viewing distance and they may be tinted to counteract blue light. And when eye muscles are severely strained, eye exercises can make a big difference in relieving the symptoms of eye strain.”

“There’s no single solution because everyone’s eyes are different. A behavioural optometrist would be able to evaluate both eyesight and the way in which eyes are used, and both could be important in developing a program to combat Computer Vision Syndrome.”
