For a diabetic, the most dangerous threat to their vision is known as diabetic retinopathy. It’s a condition in which the retina of the eye becomes scarred after diabetes-related damage to its blood vessels, and it can lead to blindness, but the good news is that even if someone is diagnosed with this condition, there are effective ways to slow or stop its progression. 

Diabetics are also more susceptible to cataracts and macular degeneration. That doesn’t mean that they are sure to develop vision problems if they’re diabetic – but if they are among those who do, early detection and treatment could save their vision. 

When and How Often Diabetics Should See an Eye Doctor

It’s a good idea for people with diabetes to go for an eye examination soon after their diagnosis. If they’ve been living with undiagnosed diabetes for some time, retinopathy may already have begun to develop. After the first screening, diabetics should have an annual eye exam – unless they notice any unusual symptoms or vision changes between check-ups. 

If retinopathy is diagnosed, eye doctors may need to follow up more frequently, and complying with a regular regimen of check-ups and treatments could be vital for maintaining their vision. “With timely and expert care, it is often possible to halt the damage caused by diabetic retinopathy,” says Gary Rodney.

Why People Sometimes Don’t Comply

Diabetes eye screening isn’t painful or invasive. Nevertheless, says Gary, many diabetics are inclined to put off their appointments. “There are several reasons for this,” says Gary. “People who have been diagnosed with diabetes are often terrified by well-meant attempts at persuading them to attend various screenings. Healthcare professionals are inclined to highlight what may happen if there isn’t regular screening, but it can be counterproductive. Patients become afraid. They put off screenings because they’re scared of getting bad news. Once they’ve put it off for long enough, they become nervous about scheduling screenings because they think they’ll be criticised for negligence.”

There’s also a practical side to things: “Drops that dilate the pupil are used for the examination,” explains Gary. “Patients aren’t able to drive after their screening. They don’t want to bother their friends or family, especially when they don’t have any worrying symptoms to report. However, Eyes in Design would like to encourage them to keep up their regular screenings, and their friends and family would surely do the same.”

Eye Screening is About the Good News

Gary says that there’s nothing to fear from an eye screening. “Eye screening is good news,” he says. “It doesn’t hurt, and if the results say there’s nothing to worry about, you can celebrate. If eye doctors do pick up the beginnings of a problem, it’s more easily treatable than if you wait until symptoms begin or become unbearable. Either way, patients can only win. If you’re a little behind on your screenings, it’s time to rectify that. Make that appointment. You’ll be glad you did.” 

“Diabetics rely on a team of healthcare professionals who will work with them to ensure the greatest possible quality of life. Optometrists are among these, and Eyes in Design is proud of its role in supporting people with diabetes through the eye-related health issues they face,” says Gary.

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.”

Behavioural optometry offers a proactive approach to eyesight that, in certain cases, reduces the chances of vision problems developing in the first place, and when its precepts are applied to children, its benefits can have particularly far-reaching implications.

It would be a mistake, however, to see behavioural optometry as a field that only benefits kids who need help in putting their eyes to work for them. Sportspeople, office workers, and people with neurological problems are among those who might benefit. Not everyone needs intervention from a behavioural optometrist, but those who do are likely to experience its evidence-based medical benefits. 

Beyond Deciding if They Need Glasses

While behavioural optometrists like Jacqueline Gattegno are able to prescribe glasses and contact lenses when they’re needed, their qualifications and experience have progressed further to include the diagnosis and treatment of issues ranging from poor eye coordination to focusing problems, lazy eye, turned eye and difficulties in tracking texts sequentially. 

Behavioural optometrists are also trained to assess what we do with information from eyes: for example, how we use it to coordinate movements, or how we synthesise visual information and auditory information. Finally, the things people use their eyes for are assessed and linked to skills that can be improved and risks that need to be combatted.

In short, behavioural optometry examines the ways in which we use our eyes, and offers therapies that include but also transcend prescription eyewear in order to help us to use vision more effectively. It can even prevent progressive deterioration in vision that may otherwise have led to a need for glasses or glasses stronger than the ones already worn. 

According to the Australian College of Behavioural Optometrists (ACBO), behavioural optometry has three goals: preventing the development or deterioration of eye and vision problems; treating the ones that are already present; and developing visual abilities, particularly those needed by children to fulfil their academic potential.

Jacqueline confirms: “From children striving to get the full benefit of their education, to active adults who realise that visual training may be as important as physical training in boosting performance, office workers who spend long hours in front of computer screens, and older people who are working to take care of their visual health, behavioural optometry can have benefits,” says Jacqueline. “It all begins with an examination in which your visual skills and needs are assessed.”

Specs, and More Than Just Specs

Apart from prescription eyewear, which is sometimes tinted to help address the impact of certain conditions on the eyes, behavioural optometry offers eye health advice, and therapeutic techniques that help with vision and vision-related challenges.

“The diagnostic methods, the therapies, and the options we offer at Eyes in Design Bondi are not unique,” says Jacqueline, “but the general public is largely unaware of them. If they don’t have problems with their eyes, they don’t need to know. But it is of concern that many adults and children are struggling with unaddressed eye-related issues.”

She says about 15% of people, and many children diagnosed with ADHD, battle with uncoordinated eye movements caused by convergence dysfunction, which affects the degree to which both eyes, which function independently, are able to work together and move in such way as to bring their independent focuses together on an object that’s close by. 

If they overdo the required turn inwards by turning too far, the overzealous turning will result an excess of convergence which causes the teamed focus to fall far short of the object. But if, on the contrary, the eyes tend to move outwards instead of inwards, their teamed focus point or convergence will be far beyond the close-up objects like books or work that are being looked at, which is seen as being as being insufficient convergence. 

The Impact of Convergence Errors

Gattegno says that it has been suggested by researchers that if left untreated and uncured, convergence excess errors may result in myopia, a serious refractive error which allows only for close vision.

When it comes to learning skills, she says convergence issues do not affect children’s ability to learn how to read, but they can impact on how they interpret and understand what they have read because the focus on the words is blurred or doubled. And these errors can also affect the fluency with which children read, specially when expected to do so for a long time. 

The energy taken in attempting to correct the double vision or clear the blur by trying to move the eyes to the right convergence point by stopping them from turning too far inward or outward, can also result in frustration and other issues. This can affect a child’s ability to read and work close up and could result in eye strain.

Increasing the negative impact of this eye muscle dysfunction, Gattegno says, is that many of those affected by it may not even know they have it; what it means; and why or how it can be corrected. 

Testing and Treating

She says neither convergence insufficiency nor convergence excess can be identified using standard eye tests; nor can they be treated with standard glasses, both of which are aimed at improving vision clarity, and not at identifying and correcting dysfunctions.

On the other hand, a binocular vision (two eye vision) assessment can determine the presence of convergence areas. The use of prism glasses and office-based vision therapy assisted by home reinforcement, have been identified as very effective ways to diagnose and correct convergence issues.

Rodney says it is quite normal that faces are not always the same shape on both sides,  usually people’s ears aren’t either, and chances are that a person’s eyes will also not be identical in shape or size. And they may have a certain amount of difference in their refractive powers. But this becomes a problem if the eyes function even slightly out of sync and move and focus differently. This can lead to problems with vision, physical health, learning, and perception, and it can possibly leave a person uncertain of their physical place in, and relationship to, the world.

When the Messages Get Confused

Among the most common of deficits in students’ vision skills, eye tracking (also called ocular motility or oculomotor function) concerns the two eyes’ ability to move up and down and from side to side simultaneously, and shift their eye alignment accurately from one object to another in a way that the two eyes can provide an understandable single visual image between them, says Rodney.

The effort required in the brain to make this happen can have huge impacts on concentration levels and abilities to process information at a higher level in the brain. Poor functional vision skills can impact in the same way making it difficult to carry on a conversation and ride a bicycle up a hill. How the eyes collaborate (or don’t) with one another in terms of these movements, can completely change the way a person sees, as well as how much they understand or perceive of what they are seeing.

Total teamwork is necessary because the data about what is being seen is received from light rays which enter each eye individually, and each send separate electrochemical messages to the brain for processing. These are seen by the brain as two different views of the same object and blended into one image. If the two eyes don’t project the same data about the colour, location and texture as well as other means of reference used by the brain, this could lead to confusion, distraction and inability to get a meaningful understanding of what is being seen.

Results of Tracking Dysfunction

When eyes aren’t able to operate as a team a long list of health issues and a great deal of discomfort may follow in the form of acknowledged symptoms like nausea, headaches, dizziness, light sensitivity, and blurry vision; as well as feelings of disorientation and being off balance when walking, which may lead to clumsiness or a tendency to bump into things.  Pain in the face and neck are also commonly experienced, and the eyes themselves may be sore due to the strain put on them during the struggle to balance their focus. 

Eye teaming and eye tracking problems can also lead to learning and reading issues, impacting on fluency, comprehension and speed when reading. This may result in misdiagnoses when it comes to learning difficulties such as dyslexia, which could toughen the chances of effective treatment for about one of every three who have been diagnosed with dyslexia.

If any of the following patterns are adopted they could be possible signs that a child has eye tracking problems, which, according to Rodney, can only really be identified through in-depth testing.

• Eye Teaming deficits may cause text or individual words to appear to “float” or “move” on the page because of the viewer’s inability to focus properly when eye movement is involved.
• Reaction to Reading: If children are overwhelmed by pages of text; avoid or resist reading; and prefer to be read to, rather than read themselves; they may have tracking difficulties. When they do read, they may find it easier to do so if the font is large, but have a slow and halting reading pattern when they read out loud.
• Physical Response to Reading: Those with tracking problems may squint or rub their eyes frequently, tilt their heads or move them from side to side, and/or use their finger as a guide to keep track of where they are in the text when reading.
• Outcome In Reading: They may guess at words they can’t identify, and lose their place when reading, writing, or copying (especially when their eyes are in the return sweep phase). Other tell-tale signs are if they leave out or transpose words or sentences when reading ( particularly if the words are small or similar), or they tend to re-read words or sentences.
• Writing: Signs there might be problems include poor handwriting, inaccuracy when it comes to word endings, low awareness of punctuation, and a tendency to reverse words or letters. Those with tracking issues may also they have difficulty when copying from the white board.
• Sports: Poor sports performance (particularly when playing games which involve moving objects, may also be a result of tracking difficulties.

HEAR: Gary Rodney Interviewed By David Wood Ultra106five.com

Rodney said the reports speak of phones and tablets braced against hands too small to hold them, and with cartoon-streaming digital devices placed in pushchair pockets close to tiny faces. 

Rodney says he does not “blame” parents for doing this. Instead he believes it is the result of a lack of awareness on many Australian parents’ part regarding how babies’ and children’s eyes develop in the first months and years of their lives, and the importance of protecting their children from becoming part of the statistics that indicate myopia will affect half the world’s population by 2050.

Pushchair Screen-time Affects a Baby’s Eyesight

Rodney says exposing babies to screens could unintentionally increase their chances of becoming myopic. Lack of time spent outdoors and too much screen time are two links identified by studies as having possible ties to the development of this treatable but incurable refractive eye condition. This has led to the American Academy of Paediatrics recommending that children under two years old should not watch screens at all, and older children should be limited to around 2 hours a day.

He said babies in prams or pushchairs are extremely vulnerable as their eyesight is still developing, and will continue to do so at least until they reach their third birthday. Newborn babies are shortsighted and unable to see further than a foot (30cm) away, without what they’re seeing becoming blurred, even if that happens to be their parents. This nearsightedness will normally disappear as the baby’s eyesight develops, but not in all cases.

An Eyesight Threat Not Just an Inconvenience

Near or short sightedness are the layman’s terms for myopia, Rodney said, labels which do not sound serious or threatening, and can often be misunderstood to be an inconvenience which can be fixed with a pair of glasses.

“These terms don’t paint a true picture of myopia and how it feels to see everything that’s more than a few feet away as a blur. It can leave a feeling of confusion in children who come to realise they cannot see, or interpret what they are seeing, as others do. For them a blur is a blur, whether it’s actually a tree, a mountain range, or even the family pet playing in the backyard. 

“Their vision is trapped where it was when they were babies in prams and pushchairs. Only now, they are not babies developing their eyesight, but children having to learn about, and react to, a world around them in a world where their eyesight has not developed in the same way as their peers’. When they go to school they are expected to assimilate information, most of which is presented in the form of images some distance away, and is often nothing but a blur to them. This can impact on performance at school,” Rodney says.

The Importance of Myopia Treatment

Unless the right treatment is given, the eye impairment can worsen progressively until children reach their late 20’s when it usually levels off. And later in life can become a serious eye problem which can lead to blindness.

Keeping Your Eye on the Ball is Not Enough

According to Rodney and Gattegno the key to top performance on the sports field lies in perceptual vision, and not just in the good eyesight determined by the Snellen charts of letters and numbers used in standard eye tests. Nor is perceptual vision purely about “keeping your eye on the ball”.

Instead it involves how athletes perceive, interpret and make sense of what they see, and how they process and respond to the “information” of the ball and its immediate surroundings. Any shortfalls in these areas of perceptual viewing can impact considerably on athletic performance levels if ignored.

“It’s not that people can’t take part in sport with perceptual vision problems. And they may even perform well. But there’s a good chance they will perform better, and be more committed to their involvement in the game, if those perceptual shortcomings are addressed,” Rodney, the founder of Smart Vision in Sydney, said.  

HEAR: Gary Rodney Interviewed By David Wood Ultra106five.com

How Sports Training Works

Rodney said players’ ability to keep their eye on the ball remains vital, but they also need to be able to judge where it is; track where it is going; and have a good idea of how fast it will get there, in order to time their response. And they also have to be aware of the environment in which the ball is travelling and any activities occurring which might affect their choice of how to respond. This involved a wide range of visual functions beyond dynamic vision.

He said perceptual vision can be improved using state of the art technology blended with the simple exercise that vision therapy provides. Programmes can be specially tailored to fit individual athletes and the sports they take part in, each of which have their own needs. These include hand-eye, eye-body and eye-foot coordination which power bodily movements as a response (tennis), excellent peripheral awareness of actions taking around them (team games) and other vision connected factors like reaction time, visual alignment, balance and depth perception. 

Support for Sports Vision Training Growing

According to Rodney, vision therapy, which tweaks any shortcomings in perceptual vision, is increasingly winning support from professional coaches and trainers operating at everything from Olympic level to those moulding the Olympic and national sports stars of tomorrow on today’s school and public fields. It’s also winning the attention of parents wanting to understand whether vision issues are behind why their children are avoiding sporting activities.

It’s also attracting the attention of researchers, who are increasingly looking at the concept of perceptual vision and its connection to performance on the field. This has resulted in the publication of several studies and papers on both the prevalence of perceptual shortcomings in players, the therapy and its level of success.

Research Results

These have lead to wide-ranging conclusions, including statistics showing that athletes taking the medals at Junior Olympic and Olympic levels sported the best overall vision. At the same time, as many as one out of three of those who didn’t make the podium had less than perfect eyesight, and one in four scored lower when screened for depth of vision and eye-hand coordination. And a relatively small section even battled with keeping their eye on the ball.

Other studies and tests have shown vision training to produce better results, particularly in team games and those involving bats and balls. One such study, where cricketers were grouped separately for cricket and vision training, showed those given the vision training showed greater performance improvement than the others. Another showed 30% improvement in baseball batting averages after vision training.
