Children's Vision TESTING

childrens vision

Children’s vision testing for all ages is provided at Peter D’Arcy ACBO Behavioural Optometrist Bega. Kids eye tests are too important to miss. Your child’s eyes and vision are so special!  Don’t forget their eye care and eye checks as well as your own eye problems.
As vision impacts learning often vision screening programs are relied on but comprehensive exams are more likely to uncover all the relevant issues and health problems. Most vision impairment is known to be preventable and curable.

Early detection of any eye condition through children’s vision testing is vital even before school age. Often children tend only to be examined if they have a problem reading a book perhaps. Only 8% of Australian children aged 0–14 have had a comprehensive vision assessment, despite an estimated one in five suffering from an undetected vision problem.

infant eye exam

 At birth, your baby’s eyes are already more than half of their adult size but not as light sensitive By 3 months  should be following moving objects at this stage and starting to reach. Infants are recommended for eye exam by 6 months of age where vision can be objectively determined and eye health established eg risk of cancers. 

Babies don’t see much detail more shades of gray  but within weeks colours.Within a few days after birth, infants prefer looking at a known face to that of a stranger.

However to perform at their best,their eyes need to as well. Reading fluency is just one measure of good vision and eye health. 
We have full ranges of children’s glasses to cater for any optical correction in glasses or contacts for that matter in addition to your child’s eye test. 

Their first eye test as very young children allows us to diagnose potential vision problems even if they are unable to read before they start to impact their quality of life but sometimes is mistakenly defered until the child starts school. Every parent wants to ensure their child sees every opportunity to grow and enjoy and reaching their full potential.  Vision is actually a skill that can be developed and improved through appropriate treatment. It’s important to note however, that addressing vision problems may only be one aspect of managing more complex learning difficulties. Visual acuity improves from about 6/120 at birth to approximately 6/9 at 6 months of age. Colour vision should be similar to that of an adult.

Children often assume their vision is just like everyone else’s, which means that vision problems can easily go undetected even eye injuries. Children’s vision and children’s eye tests are sometimes done as screenings but a full comprehensive examination can determine the eye health as well as the need for and children’s glasses.

Babies also have better eye-hand coordination at 4 to 6 months of age.Most babies are born with blue eyes because darker pigments in the iris aren’t completely developed at birth. Over time, more dark pigment is produced in the iris, which will often change your child’s eye colour.

If your baby’s eyes are misaligned an examination as soon as possible is advised to check for visual impairment as for any child vision case.
Retinopathy of prematurity (ROP). This is the abnormal replacement of normal tissue in the retina with fibrous tissue and blood vessels.  All premature babies are at risk of ROP. 

Nystagmus is an involuntary, back-and-forth movement of both eyes and can be present at birth, or it may develop weeks to months later. Risk factors include incomplete development of the optic nerve, albinism and congenital cataracts. Babies with autism have reduced eye interactions.

Commonly children can have trouble tracking when reading; they lose their place often or they move their head back and forth, rather than moving their eyes. Problems with recalling the information they have read or comprehension declines as reading continues (with fatigue).

Studies show that children who spend more than 2 hours a day on screens, and less than 1 ½ hours outdoors, are more likely to become shortsighted. 

Evidence shows that:
•   Children who spend more time outdoors are less likely to be, or to become myopic.
•   Increased study time of more than 2.5 hours per day can increase the risk of myopia.
•   Half of children and youths exceed the public health screen time recommendation of 2 h per day or less.
•   More than 2 hours of smart phone use produces greater chances of vision problems, and greater chances of multiple problems
•   Most studies on the effects of screen time in children indicate that the odds of visual symptoms increase after 2–4 hours of use.

Myopia is now recognized as a serious public health issue by the World Health Organization (WHO) and is projected to affect 50% of the world population by 2050, with nearly one billion in the high myopia category. Due to its impact on concentration and vision-related learning difficulties it can even be mistaken for other disorders such as ADHD.

Peter D’Arcy Optometrist Bega holds a MIYOSMART Accreditation certificate for myopia management and is an accredited practitioner 

Despite myopia rapidly becoming a serious public health concern worldwide, most parents do not know what myopia is. This is of significant concern given that high myopia (a refractive error of at least -5.00D in either eye) is also associated with comorbidities including retinal detachment, glaucoma, cataracts and myopic maculopathy. It has been established that managing myopia (correcting vision employing treatments and strategies) in its early stages can slow its progression, reducing the potential risk of developing high myopia and its associated conditions later in life.

Peter D’Arcy Optometrist Bega is also accredited for MiSight 1 Day prescribing and dispensing.
Misight 1 day is the world’s first daily disposable soft lens specifically developed for myopia control.  Myopia is  blurry long-distance vision, often called “short-sightedness’’ or “near-sightedness”.
This revolutionary lens technology is explicitly designed to slow myopia progression in children and teenagers.The prevalence among Australian 12-year-olds has doubled in six years. Myopia in kids tends to progress, and worsen throughout childhood, and higher levels of myopia are associated with higher eye disease risks in adulthood.

While glasses and soft contact lenses can correct the condition, until now, they have been unable to slow its rate of progression. MiSight 1 Day is a unique dual-focus lens, meaning it has alternating distance correction and treatment zones. MiSight changes the peripheral optics at the front of the eye, thereby affecting the focusing of light in the peripheral parts of the retina and modulating the growth of the eyeball. The long-term effect is that eyeball elongation is reduced, which minimises the chance of developing high levels of myopia (-6.00D or more). MiSight 1 Day may also lower the incidence of eye diseases associated with short-sightedness such as retinal detachment, glaucoma and cataracts.

This innovative contact lens is designed for children or teenagers who have a myopia prescription from -0.25 to 6.00D. While there is no minimum age for a child to be prescribed with MiSight 1 Day lenses, younger children may need assistance from parents with daily lens insertion and removal. While MiSight is new to Australia, the lens has been available for about seven years in East Asian countries such as Hong Kong, Singapore and Malaysia, where the prevalence of childhood myopia is the highest in the world and successful results have been achieved. 

We know from children’s vision testing, that myopia ( short-sightedness) is increasing and often requires glasses or contact lenses for distance vision correction. The cause is often attributed to genetic reasons and too much time being spent indoors. Ultrasound A-Scans and Optical Biometers measure axial length and are used to collate research data.
The brighter visible light causes dopamine release, and this slows down the myopic growth of the eye.

The International Myopia Institute has developed clinical management guidelines including tracking software and calculators (eg Brien Holden Vision Institute, UNSW ) to illustrate and predict evidence-based outcomes and strategies.  There are many factors in myopic progressions

Of the fast and slow progressors in conventional lenses, the aim is to get those that are progressing quickly (particularly if young) into a myopia control option.

The SV control group in the prism lens myopia control study were those who were all progressing really quickly.

If an individual isn’t progressing corrected by single vision options special myopia control treatments can be avoided. Even after cataract extraction myopic progression or tendency can sometimes continue. The Brien Holden myopia calculator tries to estimate the progression in SV lenses that might occur, but it is an estimate only and not individual.

Progressive lenses sometimes can be used-

  • as an entry point for parents and patients who don’t want either soft multifocal contact lenses  or ortho K types
  • an adjunct for when the patient is not wearing their contacts
  • as alternatives such as prism controlled executive bifocals
  • as alternatives such as Eyezen (extended near lenses) – now that higher concentrations of atropine are used where accommodation may be impaired.
  • For kids vision as well as adults
kids glasses

Genetics,environmental and social factors are major influences on myopia. Evidence shows that time spent outdoors in childhood partially protects against the development of myopia and in countries such as China where the condition is rampant such policies are being enforced in schools.

In areas such as dyslexia bad advice or simplistic advice can abound  for treating conditions such as  amblyopia or visual dyslexia.


Screen time recommendations

undetected vision problems

AGE                      EXPOSURE                    
0 – 2 Years           None                                
2 -5 Years            1 hour per day or less    
5 – 18 Years         2 hours per day or less 

Excessive computer and screen use has been shown to be associated with a greater risk of developing shortsightedness as well as increased symptoms of eyestrain, headaches, blurred vision, dry eyes, and neck and shoulder pain. 

Ensure Good Posture – device should be no closer than the distance to the elbow. 
Looking away after every 20 minutes of continuous near focusing, and a physical break every hour for children under the age of 9 years of age is recommnded.
Stop screen use for an hour before bed time

 Amblyopia, commonly known as a lazy eye occurs when the brain does not fully acknowledge the images seen by the affected eye found in about  3 % of children.
 It is also the most common cause of monocular (one eye) visual impairment among young and middle-aged adults.

why do childrens eyes need extra protection

Treating amblyopia lazy eye involves forcing more use of the eye with weaker vision. Pairs of glasses may be required to aid focus,concentration and to avoid suppression.  

  • Patching treatment or medication to blur non amblyopic eye to allow more input from the amblyopic eye. 
  • An adhesive patch is worn over the stronger eye for weeks to months or daily patching.
  • <3 hrs per day effective if < 4yrs age 
  • >3hrs per day required if > 4 years of age

Vision is responsible for around 80% of all learning during a child’s first 12 years ^   

This is why chidren’s vision testing is so important with or without family history being relevant 

Protect children’s eyes and help them to learn by seeing as well as possible even before school age.
School vision screenings are not as comprehensive as an optometrist examination
We have a duty to ensure  eye care for distance vision and near vision is  balanced,healthy and comfortable as possible. Kids glasses can be prescribed and vision training instigated as required
^Vision council of america, making the grade, 2009.

A detected and treated  lazy eye found from a children’s eye examination means vision problems will not limit a child’s learning potential. It may be as simple as a contact lens for balanced distance or near vision.

Amblyopia can result from any condition that prevents the eye from focusing clearly. Amblyopia can be caused by the misalignment of the two eyes (known as strabismus) where the eyes can cross in (esotropia) or turn out (exotropia). Occasionally, amblyopia is caused by cataract.

Children and even adults whose amblyopia persists despite the recommended two hours of daily patching may improve if daily patching is extended to 6 hours. The brain’s plasticity makes the condition most treatable.

Vision development is a vital concern of any eye doctor.Eye exams will detect eye problems including vision or lazy eye that require kids glasses or contacts.Such eye health checks need to be ongoing from young children as well as measuring refractive error, distance vision,teaming and near performance 

Erasmus Darwin  introduced occlusion therapy for amblyopia. The  Pediatric Eye Disease Investigator Group (PEDIG) Amblyopia Treatment Studies (ATS) including Monitored Occlusion Treatment of Amblyopia Study (MOTAS) have refined the techniques for treatment.

Vision therapy/training integrated for brain,eyes and body can be employed that specifically targets and enhances the quality of visual and oculomotor control for young children through to adults. Children with peripheral visual deficits performed significantly worse on tasks that required visual attention than the normal vision peers and children with poor central vision (Tadin et al., 2012).

Eye muscle surgery for strabismus can involve: 

Recession is when an eye muscle is detached and then reattached further away from the front of the eye to weaken the muscle.

Resection is when a portion of an eye muscle is removed to make the muscle stronger.

Chidrens Vision is  often assumed  is just like everyone else’s, which means that vision problems can easily go undetected such as ambylopia lazy eye.
Poor vision can interfere with their ability to learn and develop. A developmental or paediatric optometrist that concentrates on the way vision is interpreted is known as a behavourial optometrist.

Many parents find that it can be difficult to ensure that their child is wearing protective eyewear, especially in situations when they may not be present, like walking to or from school and during recess.

So for our kids be they in Narooma or Eden, Tathra to Bombala, Bega, Merimbula or elsewhere children’s vision testing is one test too important to miss. A children’s eye test is often forgotten in eye care as young children will not self report their eye condition. Establishing good vision means identifying children’s eye and vision problems by thorough eye checks in an eye examination.

Kid’s eyes need protection, too.  In fact, children are more at risk of the eye-damaging effects of UV exposure than adults.  The eye of a child under the age of ten allows more than six times the amount of UV light to penetrate than an adult’s eye, so it’s never too early to start protecting a child’s eyes.

Children’s eyes are more transparent and the UVA, UVB and UVC can all penetrate deeper into the eye structure than an adults eye. Most literature is based on an adults eye that has had changes to the transmission properties caused by sunlight. Transitions lenses can help.  They block 100% of UV radiation and reduce glare.  And they’re available in the sturdy, lightweight, shatter and impact-resistant materials that are best for children. A child’s retina can be damaged by UVB because the lens has only a small ability to absorb UVB, even though less than 2% of  UVB is thought to penetrate through the lens of an adult eye.
Even if UVC does not penetrate beyond the lens, it can still cause damage to other structures of the eye. The conjunctiva is more sensitive to UV than the cornea and the skin around the eye can also be affected by the ultraviolet radiation

Hundreds of thousands of Australians are immersed for too long in virtual reality headsets eg Google, Samsung, Sony.  
Eye strain and dizziness can easily result as the focus and convergence are more disassociated and may require longer and more frequent breaks than actually occur as the experience can be addictive for some especially children.
Nowadays the majority of children (even preschoolers) report digital eye strain when using digital devices and are found to have dry eye issues from inefficient blinking and blue light from screens.
Computer vision syndrome is now called digital eye strain because it related to all digital device use not just computers.

The Telsyte Australian Virtual Reality and Augmented Reality report predicts a quarter of Australian homes will have a VR headset by 2021. 
At a minimum use the 20-20-20 rule. Every 20 minutes, take a 20-second break and focus your eyes on something at least 20 feet (6metres) away performing some clockwise and anticlockwise movements, stand up and blink completely! 

Have your children’s eyes examined every couple of years as a general guideline. It can help with their development such as autism and dsylexia cases in fact all cases
