She says the consequences of staring at smartphones too much and too long go far further than temporary “computer fatigue”, currently describing the side-effects of screen overtime and the short wavelength blue light screens emit. And not even those who’ve passed the standard 20/20 eye test with flying colours, and show no clear signs of vision problems, are totally immune to it. 

“In spite of this, children are still owning smartphones and using them far more than an hour a day. Instead they are using them almost all the time, whether they’re at school, at home, or even after getting into bed at night. And sometimes those whose eyesight is still developing, have not yet started school, and are still in prams or pushchairs, are doing the same,” Gattegno said. 

New Research Reveals Smartphone’s Threats

According to Gattegno, new research and statistics have suggested smartphones could be contributing to the epidemic levels of myopia, the shortsighted refractive error predicted to affect the vision of 50% of the global population by 2050. And other research has reported finding imbalances similar to those seen in people with mental illnesses in the brain chemistry of young smartphone users who spend a large amount of time staring at them. 

Other studies have linked even one hour a day spent staring at a smartphone screen with a significant rise in anxiety and depression among children. Gattegno says it’s also been associated with a drop in children’s curiosity about the world around them, and an increase in the amount of bad behaviour like bullying, short attention spans, and low performance at school, with most of these attributed to the instant gratification and constant streams of information, sound and colour, provided by mobiles, which could overwhelm the brain and distort the children’s perceptual vision skills.

Tips on How to Lower the Risks

Gattegno says that the best way to avoid these threats, is to reduce the time spent staring at screens by setting boundaries on the time young eyes spend focused on them. 

The smartphones themselves provide some assistance in the form of anti-glare screens and settings which reduce the emission of blue light, which studies now show may actually damage the cornea and impact badly on vision. It’s also possible to adjust the brightness and contrast, as well as the size of the text, all of which go some way towards reducing potential harm to the eyes. Keeping the screen clean and clear of blotchy fingerprints, and teaching children to blink frequently when watching the screen, will help protect their eyes from getting dry and help reduce eye strain, as will ensuring the screen is at least 16 inches away from their eyes while they are watching.

Gattegno says it’s also wise to involve children in other activities which will help their eyes and at the same time distract them from the screen.  Time outside, engaging with nature under natural light and doing some exercise, is the best answer. It also creates an opportunity to implement the 20/20/20 rule of eye care, which recommends that every 20 minutes children should look at something 20 feet away for at least 20 seconds, and take a 15-minute break from any type of screen every 50 minutes.

Rodney, founder of Smart Vision Optometry, says that while more parents (and schools) are becoming aware of the need to check children’s eyesight each year before school opens, they are settling for standard eye tests which report on whether or not they can see objects at a distance of 20ft (the average level of distance sight) and earn the 20/20 rating which simply indicates how well each eye can do so.

What it doesn’t show, and is largely ignored until behaviour or lack of performance raises its head as school progresses, is that even with 20/20 eyesight, children may have vision problems which deprive them of the ability to understand what they are seeing, and leave them without the perceptual vision skills they need to process information in the school environment.

Learning Requires More Than Good Eyesight

Learning and performing well at school requires not only good eyesight, which is processed by the brain and eyes, but also the interpretive mental or thought process of perceptual vision. Backing this is the need for eyes that team well, focus on the same point at the same time, can track objects as they move, follow letters across the page.

And they should have an efficient focusing system that is flexible enough to allow for switching focus from near to far on a regular basis as focus shifting is particularly necessary in classrooms, where children are asked to copy words written on the blackboard at the other end of the room, into books that are on their desks only about 20 inches away from their eyes, says Gattegno.

How to Improve the Vision Side of Learning

Rodney says that vision skills and the visual process are a core part of behavioural optometry. Rather than testing how clearly children can see letters across a room as a standard eye test does, it instead looks at the functional and perceptual vision skills, which reveal how well the vision system is functionally able to concentrate and visually attend, and the level at which the brain processes visual information.

Perceptual vision skills, Rodney says, are an essential part of successful learning, and if these are not operating normally, they can seriously impact on children’s physical and mental performance and behaviour at school. However, by doing so, they can also sound the alarm that something may not be right with their vision, and provide a call to action to have their vision skills checked. Fortunately, these skill deficits can often be corrected with vision therapy and training.

The Vision Skills Toolbox

In an ideal situation, Rodney says children should have most of the following vision skills, and be able to draw on them to help their learning performance. But just being unable to apply one or two of them, could affect their lives and their learning considerably.

Visual Spatial Relations: A vital part of perceptual vision lies in the viewer seeing their position in relation to objects, and recognise the space between them. This affects their understanding of the concepts of up, down and sideways, as well as the ideas behind left, right, next to, and under. These factors can impact severely on reading; letter and number formation; and movement through crowds. It can also affect their balance, and lead to clumsiness.

Visual discrimination is about seeing and identifying the differences between objects and forms, particularly when they are very similar. These include letters such as “d” and “b”, which are the same shape turned back to front, or numbers like “6” and “9” where one is simply turned upside down to create the other.

Form constancy is the ability to mentally manipulate objects, and visualise the results in a way that two objects can be recognised as being the same, even if they are different in size, colour, or orientation.

Visual Memory allows information which has already been received visually before to be recalled for use as a reference in dealing with new words or facts.

Sequential Memory is the vision skill that, if it’s properly developed, makes it possible to remember characters or forms like cellphone numbers and lists in the right order.

Visual Closure involves matching two items even when one of them has some parts of it missing.

Visual Figure Ground: This is like finding the needle in the haystack. It involves the ability to identify something which is surrounded by other, distracting items.

Epidemics Don’t Leave Quietly

Rodney says these eye experts are concerned that the myopia epidemic will bring about a “new normal” of its own, and they are even more concerned that it may have already done so through its close relationship with urban areas and the lifestyles people follow there.

“Any epidemic, or a pandemic like the current Covid-19 virus, will leave chaos in its wake as it runs through the world’s population. And it won’t be just its effects on the physical health of those it’s targeted that will be left behind. There will also be a trail of physical, emotional, and social stress that will affect millions of people’s lives and how they live them. And the Myopia epidemic is no exception. It’s been leaving a widening trail of people with this refractive error since it started its upward curve in the 1970s,” Rodney says. 

Statistics show that developed and urbanised countries like the USA, UK, South America, East Asia and some European countries, have been hardest hit by the myopic onslaught and have the biggest number of people dealing with the eye impairment which leads to their seeing anything further than 20ft away as a blur, and only having clear vision when looking at something close to hand. Unable to see the whole or long-term picture the same way as those with normal vision, many myopics (and specially those who have severe levels of myopia) tend to adopt a world view based on their own shortened and narrowed perception of views, objects and actions that are only clear when close by.

Urbanisation Growing Alongside Myopia

According to Rodney urban lifestyle could seem to be an ideal place for myopics to thrive. It’s surroundings, environment, culture and focuses revolve around speed in manufacture and development; quick turn-around time; short-term investments, and large debts; close work; inside living; take-out meals; and multiple screens, all of which exclude long-term views, plans and concern about consequences. And it seems the cities have happily accepted them, as well as the wider understanding and use of the word “myopia” and concept of shortsightedness, which are both becoming popular topics and descriptions of attitudes outside the vision arena. After many years of dormancy, these old-fashioned terms are back in political and business rhetoric to challenge speeches or decisions considered to be ignoring the long term and its consequences; and in psychology, “mental myopia” is being used to describe someone’s narrow and biased reactions to others.

However, instead of seeing this as an ideal arrangement, Rodney says matching urbanisation and myopia appears to increase the onset of myopia and the speed at which it progresses, while increased numbers of myopics may raise the influence of short-term approach to work and lifestyle in the city as it expands its share of the population.

The jury is still out as to which came first, and which will have the greatest impact on living and seeing in a myopic world. That’s because alongside the myopia epidemic, and with similar timing, urbanisation numbers have also been soaring upwards in their own “epidemic” since the 1970’s. Since then it’s risen from 1,3billion, or a third of the population living in or near cities, to 3,3billion (or half the population) by 2007, and reached 4,62billion in 2019. And by 2050, 6billion city dwellers (or two out of three of the world’s population), are expected to be crowded into cities which already house more than half the world’s population on less than 10% of the earth’s habitable land.
