Myopia, or shortsightedness as it is commonly known, is on the rise. It’s the most common eye disorder in the world, and the biggest cause of visual impairment, especially in children. The facts are there for all to see. In 2010, an estimated 27 percent of people were struggling with a significant level of myopia, and by 2050, that figure is expected to rise to 52 percent.

The fact that myopia is linked to genetics is not disputed. However, genetics alone would not be enough to account for the rising incidence of myopia, and it’s now believed that environmental factors also play a role. Whatever the reasons for the rise of myopia, there have also been advances in its treatment. According to Australian behavioural optometrist Jacqueline Gattegno, reducing the progression of myopia is a real possibility – provided that intervention happens soon enough.

Myopia Control Treatments

Jacqueline says that contrary to popular belief, Myopia is a childhood problem. “It’s related to an increase in the axial length of the eyeball which results in poor focus on the retina. The progressive lengthening of the eyeball occurs during growth, with the eyes generally stabilising around the age of twenty. If myopia’s progression is to be slowed, treatment must occur during this time,” says Jacqueline. “Various non-surgical, drug-free methods have been explored, with the greatest successes coming from orthokeratology and the use of peripheral defocus lenses.”

Atropine drops appear in a lot of the research literature, but Jacqueline isn’t convinced that their use should be attempted or that they will result in the best possible outcomes. “There are side-effects,” says Jacqueline, “and the drops only seem to offer myopia control benefits during their first year of use. Following excellent results in early trials, it’s now widely believed that atropine drops don’t have sufficient long-term benefits to justify their use. Orthokeratology is drug-free and it works. There’s no reason to use a drug-based treatment.”  

Efficacy of Orthokeratology in Myopia Control

Studies support Jacqueline’s confidence in orthokeratology for myopia control, and the treatment itself is remarkably simple. Optometrists carefully map the eye and then create hard contact lenses that gently mould the cornea to allow for better light focus on the retina. The lenses aren’t worn by day. Instead, they’re worn during sleep, and the eye maintains the correct shape during waking hours.

Research shows that orthokeratology, or Ortho-K, can slow the progression of myopia in children by 36 to 56 percent. “It’s known that the higher the level of myopia in people of any age, the greater the risk of certain ocular pathologies that can lead to vision loss,” says Jacqueline, “so reducing myopia in childhood not only offers a good chance of better vision during adulthood, but may even prevent conditions like retinal detachment and age-related blindness’ later on.”

Myopia Control at Home

There’s at least one other therapy that can help children in slowing the progression of myopia – and parents can practice it for free at home. “Tell the kids to go and play outside,” says Jacqueline. “There have been some remarkable studies that have shown that just spending more time outdoors reduces the risk of rapid myopia progression. There was a measurable reduction in axial elongation and myopic shift during trials in Asia, and some experts even theorise that reduced time outdoors might be at least partially to blame for the myopia epidemic that’s currently being witnessed.”

It’s Time the World Started Talking About It

Jacqueline believes that the combination of orthokeratology and a healthy, active lifestyle can make a difference in combating the rise of myopia but is concerned that myopia control isn’t more widely talked-about. “Many parents have never heard of ortho-K or myopia control. They know about glasses and contact lenses, and they bring their children to get prescription eyewear. That provides an opportunity to tell them about treatment options, but it isn’t ideal.”

“Myopia control should be headline news. It’s exciting. The benefits are beyond price. It’s time the world started talking about it because we’re rapidly heading towards a situation in which half the world’s population is myopic with high myopes facing further risks to their vision,” concludes Jacqueline.

Most stereotypes are based on prejudice, but occasionally, one pops up that’s based on fact – even if only remotely. “Smart kids wear glasses” could be among them, at least up to a point. Australian behavioural optometrist Jacqueline Gattegno sheds light on what is known regarding the intriguing link between myopia and IQ.

Studies Show that a Higher Percentage of Myopic Children do Well at School

The results of a 1958 study are tantalising. US-based researchers reported that children with myopia are inclined to have a higher IQ. Czech, Danish, and Israeli researchers were among those to corroborate the finding. This may seem like an open-and-shut conclusion, but nothing is ever as simple as it seems.

Related research showed that myopic children, regardless of IQ, tended to do better at school. With this piece of information to digest, it might seem that studying harder, better results, and myopia are all linked.

Long hours of study can certainly cause eye strain, this can lead to elongation of the eyeball which is myopia. Additionally, there’s a clear link between too much time spent indoors and myopia, indicating that the absence of natural light is also a problem for studious children.

However, researchers were alert to the question of whether higher IQs and myopia were related, and their investigations continued. Subsequent studies published in 2004 and 2006 by Professor Seang-Mei Saw and colleagues concluded that children with myopia really did tend to have higher IQs regardless of how much time they spent reading and studying.

Why Myopia and IQ are Linked

Given that research had shown the link between Myopia and higher IQ regardless of time spent hitting the books, the next question to address would be why children with myopia tended to have higher IQs. Unfortunately, the answer to that remains a matter for scientific speculation.

Professor Saw and her team of Singaporean researchers observed that there might be a link between the genes determining a predisposition to myopia and a higher IQ with the same sets of genes influencing both traits at once. They added the thought that genes affecting eye size and growth, which are linked to myopia, may also influence neocortical size, a factor which may be associated with IQ.

Many Kids with Myopia Can Live Without Glasses

“There seems to be a grain of scientific truth behind the myth that smart kids wear glasses,” says Jacqueline, “but advances in myopia control may change that. Already, children who are developing myopia are going without glasses or contact lenses. They are seeing perfectly thanks to orthokeratology, a non-surgical treatment that uses night-time wear of hard contact lenses.”“They reshape the cornea, not only eliminating the need for day-to-day correction for myopia, but also its progression. This type of treatment is already widely used. It is to be hoped that in time, there will be further advances in this field, and that children all over the world will have access to myopia control treatments. As a result, children with a predisposition towards myopia may not have to live with short-sightedness and may not need corrective eyewear at all. That will certainly be a happy ending.”

Myopia Then and Now

The rising prevalence of myopia is all that’s needed to show that it’s not just a refractive error that glasses will fix. It’s a lifestyle problem with genetic roots, and it’s linked to much more serious eye conditions including glaucoma, retinal detachment, and an increased risk of blindness. 

With myopia on the rise in the West, digital screens are bearing the brunt of the blame, but, says Gary, the rise in myopia was already noticed in Asia long before screens became part of daily life. “Broadly speaking, near work and lack of time spent outdoors in natural daylight seem to be the lifestyle changes that are affecting children’s eyesight,” says Gary. “Nowadays, near work quite often means screen time. However, long hours of study without a computer may have a similar effect.” 

But there’s more to myopia than too much study and not enough outdoor play. “Genetics still play a role,” says Gary. “However, the expression of genes is determined, to some extent, by environmental factors, so it would be unwise to overlook their influence. The adverse effects of near work and the absence of the beneficial effects of time spent outdoors will have an impact, and a genetic predisposition to myopia would add to the potentially negative effects of both.”

How Eye Doctors Slow Myopia Progression

Progressive myopia first manifests itself in children. The younger they are when it begins, the faster it progresses. Later on, usually at around the age of 20 to 25, the progression of myopia slows down. However we now know there are certain categories of the population that continue to get worse even as adults. The eyeball continues to elongate and stretch and damage the retina. The thinking behind myopia control is logical. “If the progression of short sightedness can be slowed or stopped in children, the adult will have better vision,” says Gary. “As a result, children are the primary focus of myopia control interventions.” 

Various treatments have been tested in clinical trials, and needless to say, there were some failures. “At one time, it was believed that providing corrective eyewear that helped myopic kids to see properly was part of the problem. Thankfully, a trial in which children were prescribed eyewear that wasn’t strong enough proved that forcing kids to struggle with their eyesight wasn’t going to solve any problems. We now know that the worse thing you can do to contribute to someone’s eyes getting worse is to under correct the prescription or to prescribe single focus distance glasses or contact lenses.”

At his practice in Mosman, Gary Rodney uses orthokeratology as a way to combat myopia in children. “Kids wear special contact lenses that reshape the cornea at night while they sleep. In most instances, myopia control is that easy,” says Gary, who also promotes the idea of more outdoor playtime. “There are various theories as to why playing outdoors in natural light slows the development and progression of myopia. Whatever the precise mechanism, it’s known that outdoor play makes a significant difference and is therefore to be recommended.”

“The ultimate goal for any optometrist would be the prevention of blindness. He or she will probably never know how many of today’s children are saved from blindness through myopia control interventions, but it’s a calling that can change lives and therefore one that Eyes in Design is passionate about.”

Kids With Myopia Aren’t Necessarily Undernourished 

“Studies often produce tantalising results that are all-too-easy to misinterpret,” says Jacqueline. “For example, a famous study found that children who developed myopia ate less energy-rich foods, had a lower intake of B-vitamins and vitamin C, and ate less fatty and protein-rich foods.”

“That may seem conclusive enough, but it was found that there were no significant height or weight differences between myopic children and their peers, which would be expected when nutritional intake was low enough to indicate malnourishment. As a result, the researchers were forced to conclude that the myopes weren’t undernourished and may just have represented a group with a lower energy requirement.” 

“The point about physical energy requirements opens the door to speculation. There is definitely research showing a link between spending too much time indoors and the progression of short-sightedness. However, we don’t know anything about indoor versus outdoor activity in the group with ‘lower energy requirements.’ It’s certainly possible that this was a more sedentary group that spent less time in outdoor play, but even if it was, it can’t be known whether the same nutritional findings would have applied had both myopic and non-myopic groups of children been exposed to the same levels of activity, particularly outdoor activity.”

A Balanced Diet for a Healthy Body

Sometimes, it’s best to take an uncomplicated view to eliminate confusion, and that’s just what Jacqueline does. “It’s an accepted fact that a healthy, balanced diet is important to one’s health, and there’s no reason to believe that eye-health is any different. There are certain foods that are linked to the maintenance of eye-health, but they shouldn’t be viewed in isolation. Balance will always be key in nutrition and a balanced diet should benefit eye-health along with overall physical health.”

Balance is certainly a sensible approach, but knowing which foods (other than carrots) are best for maintaining healthy eyes and possibly even clear vision is nevertheless of interest. As with all things eye-related, Jacqueline has the available information at her fingertips.

Feast the Eyes

“Oily fish like herring, mackerel, sardines, salmon and tuna top the list. There’s evidence that the Omega-3s found in oily fish can contribute to reducing dry eye issues, and Omega-3s are linked to a host of other health benefits,” says Jacqueline.  Seeds and nuts also contain Omega-3s, and unless there are allergies to add to the equation, they’re a healthy snack food for between-meals nibbling. 

“Antioxidant vitamins are believed to protect against various age-related eye problems, and the best source of these nutrients is to be found in fresh fruits and vegetables. Once again, the whole body benefits and people of all ages can enjoy better health. And yes, carrots are good because they contain Vitamin A – so the old urban legend wasn’t altogether wrong.”

“Beef and eggs contain zinc, which is an element found in higher levels in the eyes than elsewhere in the body, so it’s possible that both of these foods, as well as other foods containing this trace element, are good for the eyes.”

Last but not least, Jacqueline observes that water helps to keep the body functioning as it should, and that applies to the eyes too. It is known that staying hydrated can help to reduce dry eye symptoms, and that’s just one of the many benefits of drinking enough water. By now, we’ve covered most of the ingredients of a balanced diet, but it does serve to illustrate that there’s no ‘silver bullet’ when it comes to eating for healthier eyes and better vision.”

She says those four senses perform very important roles in the brain’s processing of sensory data into vision that’s accurate, relevant, meaningful, and usable so that people can understand what they see and react accordingly to it, as well as function properly in their surroundings. Without them, the visual image could be compromised, causing the viewer to feel estranged and confused. 

Working as a Team

All five senses are in a team, and intertwined when it comes to how they operate. This makes it not only possible for them and the brain to keep in contact and work together in order to ensure the best processing of sight’s data. Gattegno says it also means that one of them can step in and cover when another, including sight, loses its ability to function properly. With training, the sense of hearing has been shown to assist the blind, and for those who are deaf as well as blind, touch can play an important role in functioning. It’s also possible that if the sense of taste fails for some reason, sight and smell might cause the food to “taste” the same.

Loading the Reference Bank

Their primary role is to help load the various “memory libraries” of specific information gathered by the brain for reference when processing the electrochemical data received from the eyes about what is seen. Their input adds a different variety and nature of information to the data received by the eyes, which is made up purely of colour, light and shape, and affect how the end picture is perceived, interpreted and understood.

How the Senses Work

All five senses collect information in reaction to different specific stimuli and the sensations or vibrations they create. For the eyes (sight) and ears (audition) stimuli are in the form of light waves and sound waves respectively. Taste (gustation) and smell (olfaction), which are closely intertwined, are known as the chemical senses because they respond to chemical stimuli rather than light or sound waves; and textures provide the stimuli to the tactile sense of touch or somatosensation, Gattegno says. 

Touch’s information is converted in mechanoreceptors on the skin before being sent to the brain; sight by the retina from light rays falling on it; hearing from drum-like vibration in the inner ear; smells in the nasal area; and taste in the taste buds on the tongue.

She says that once the data and information is collected, all five senses send their own signals to the brain for processing using sensory neurons and individual sense-specific receptors which accept their messages, and them only, for conversion into electrical signals.

He welcomes both the annual international Myopia Awareness Week in May, and the World Council of Optometry (WCO) Board of Directors decision to approve a resolution which advises optometrists to incorporate a standard of care for myopia management in their practices. This includes three approaches aimed at advising parents and patients on risk factors in order to delay the onset of myopia; regular eye tests which, when possible, include measuring the myopia refractive error and axial length; as well as a management programme based on correcting and controlling myopia with an eye to patients’ future eye health and quality of life.

Getting Myopia and its Management Under Control

Rodney says he is hopeful that these and other similar programmes, together with a new generation of myopia treatments might stop the existing lack of consensus as to ways to treat and manage this so-far incurable vision problem, which has been increasing its prevalence at epidemic level year after year, and impacted on more and more people’s sight and lives.

“A considerable increase in awareness and consensus on treatment and management of this vision error could show some light at the end of its blurry tunnel. It’s just sad that reaching this point has taken almost as many years as it’s taken for myopia to increase from affecting a small and manageable number of children to a point at which it’s projected to affect every second person by 2050. And even sadder, is that we have still not found a cure for myopia,” Rodney says. 

He said a recent global survey revealed that 82% of eye care professions expressed concern that their young patients would face the impact of serious eye health and myopia issues as they got older. But what was troubling to him, was that more than half of them laid the problem at the door of parents’ lack of awareness. Yet, according to another survey in Australia, many of them were themselves not taking advantage of the new methods of myopia treatment and control. 

According to Rodney, more than half of the respondents said they were still using single vision distance glasses to treat child myopia, and providing new and stronger glasses each year as the myopia continued to progress, despite their being aware of newer approaches and treatments that were proving to be more successful. 

And, at the same time, more and more eye specialists and scientists were agreeing that single vision glasses, the accepted method for treating myopia for many decades, do little more than clearing distance sight with a series of increasingly strong lenses, and may actually increase the progression of the vision error.

Why Myopia Management is So Important

He says that nearsightedness develops when either the cornea or the eye’s lens have an abnormal shape, or the eyeball is too long. This can cause the focus of messages carried into the eyes to be in front of the retina rather than on it, resulting in blurred distance vision. But many people are unaware that myopia is about far more than this. 

Rodney says It has been linked to the world’s largest causes of vision loss, cataract, glaucoma, macular degeneration and retinal detachment, and according to its level of severeness, puts people with myopia at greater risk of getting them. With moderate myopia the risks of glaucoma double, cataract triples, retinal detachments are nine times greater, and macular degeneration ten times more likely. If myopia is allowed to progress to the high myopia level, the risks rise to three times higher for glaucoma, five times for cataract, and the chances of a detached retina increase by 21 times, while the risk of macular degeneration rises to 40 times more. 

Moves Away from Standard Glasses for Myopics

While myopia treatments have mostly moved towards the use of specially-designed contact lenses of various types, including both multi-focus and single distance lenses, when it comes to Orthokeratology the contact lens is part of an overnight treatment programme. This contact lens is gas-permeable and temporarily reshapes the cornea, and if properly used on a nightly basis, has been shown to enable myopes to not have to wear glasses during the day.

Two new ideas have entered the myopia treatment sector recently, one of which is a is a single-day contact lens clinically proven to slow myopia progression when used early enough in the progression. The other, Rodney says, returns to the idea of ordinary single-vision glasses. However, this new pair of spectacles is not ordinary, instead using spectacle lenses which have either slightly or highly aspherical lenslets.

She says that everyday stresses in today’s world, whether negative or positive, have put people under pressure and made them feel they’ve lost control. With stresses brought about by factors such as close work, long hours, heavy concentration levels, large amounts of screen time, health and financial problems; it’s not surprising that the prevalence of vision problems is rising with the stress levels.

Stress and Vision: A Vicious Cycle

“Stress creates a vicious cycle, leading to many health problems like depression, high blood pressure, worry and fear, all of which, in turn, push stress levels still higher. And the same happens with its effect on vision,” Gattegno says.

“What powers the cycle to keep on turning is the increased levels of stress hormones, and particularly cortisol, which are set in action as the body switches to fight or flight mode to protect itself against what is interpreted as a threat. These hormones raise blood pressure, cause the heart to beat faster, boost metabolism, and dilate the pupils in the eyes in preparation for an eminent battle, but stress is different in that it can last for long periods.”

“Stress can cause sensitivity to light and movement; bring on dizziness and headaches. And it can also lead to eye twitching; dry or extremely watery eyes; blurred vision; eye strain; small floaters; and eyes that feel tight and swollen,” Gattegno says. “Importantly, it can also affect the ability to concentrate and focus, and sometimes result in sudden and temporary blindness, or even lead to vision loss.”

As Stress Levels Rise So Does the Vision Threat

She says short spells of stress usually have a temporary impact on vision which can disappear of its own accord within a few weeks if the cause of the stress is removed. It’s advisable to consult an eye doctor if the vision problems continue for even a short while. 

Recent studies indicate that long-term stress can cause permanent vision damage and even result in vision loss.

“Raised levels of stress hormones (and cortisol in particular) can impact on important nervous systems, eyes, and even the brain, by disrupting blood flow in those areas. This could lead to optic neuropathy which causes eye pain, double vision, and loss of peripheral or side vision and colour vision and it may also increase the pressure in the eyes, causing (or worsening) glaucoma, an irreversible eye disease which can lead to vision loss,” says Gattegno.

However, according to Australian behavioural optometrists Jacqueline Gattegno and Gary Rodney, many don’t realise that the lack of sleep can have far more serious effects on their eyesight and vision than merely spoiling their aesthetics or their mood, or that some even lead to vision loss.

Why A Good Night’s Sleep is Necessary

According to Rodney, a master of optometry and fellow of the International Academy of Orthokeratology and Myopia Control (FIAOMC), regularly having the correct amount of the right sort of sleep leads to better and clearer eyesight, vision, and eye function. The recommended amount is 7 to 8 hours at night for adults, longer for teenagers, and still more for young children whose eyes are still developing.

These extended sleep periods provide adequate time for restoring and renewing the cells, lubricating the eyes, and improving the health of the tissues, nerves and muscles in and around the eyes. Not giving the eyes this vital time for maintenance can result in nothing more than a little discomfort in the short-term, but it can also seriously affect the eyes and visual system, and can sometimes lead to impaired vision or blindness, says Gattegno.

How Lack of Sleep Can Affect the Eyes

• The Eye Spasms and Twitching experienced after a short or restless night’s sleep, probably won’t harm vision permanently, but they can be extremely irritating and distracting at the very least. Rodney says they may also affect the ability to focus, and influence the ability to perform everyday functions such as driving, working on the computer, or reading.
  
• Dry Eye Syndrome is caused when the eyes don’t produce enough tears (or they evaporate too soon) to clean and lubricate the eyes. While this can occur naturally, Rodney says it is also associated with too much time spent watching screens with a fixed focus, and little blinking or eye movement. And it can also result from too little sleep.

He says all these habits limit the tears eyes build up during blinking or sleeping, and affects their ability to circulate them in order to keep the eyes lubricated. The result can cause headaches; itchy, scratchy or red eyes; blurred vision; increased light sensitivity; stringy mucus in and around the eyes; eye infections and eye fatigue. But, when it happens too often, it can also lead to scratches developing on the cornea which covers the eye and protects it against UV light rays, and may even result in total vision loss if left untreated.

• The most severe eye impairments, and the most likely to cause vision loss, flourish in a poor health environment, according to Rodney. Two of the best known are Glaucoma, which builds up pressure inside the eyes to a point where it damages the optic nerve and, starting with the peripheral vision, gradually leads to total vision loss; and Diabetic Retinopathy, which, in reaction to Diabetes 2, damages the blood vessels in the retina, which normally act as the landing point for the light rays delivering information about what is seen for transfer to the brain.
  
• A rarer vision condition, Anterior Ischemic Optic Neuropathy (AION), also seems to have a connection with sleep loss, and particularly where the sleep-deprived person has sleep apnea. This causes inflammation in the eye blood vessels, which can also result in vision loss over time.
