My Kid's Vision is a free online tool that helps parents assess and manage myopia risks for their kids.

Myopia (often called short sightedness) is an eye health issue that every parent should be aware of but may not know about.

What is this? A 6 question survey and specific advice based on your child's risk of myopia development or worsening.

What is myopia?

Myopia is blurry long-distance vision, often called “short-sighted’’ or “near-sighted”. A person with myopia can see clearly up close – when reading a book or looking at a phone – but words and objects look fuzzy on a blackboard, on television or when driving. But a pair of glasses aren't the whole story.

The prevalence among Australian 12 year olds has doubled in 6 years. Myopia in kids tends to progress or get worse throughout childhood, and higher levels of myopia are associated with higher eye disease risks in adulthood. If your child already wears glasses, you can do something to stop their vision worsening. If they don't you can assess their risk of developing myopia.

  • Myopia occurs when the eyeball grows too quickly in childhood, or starts growing again in adulthood

  • Childhood onset myopia is most commonly caused by the eyes growing too quickly, or continuing to grow after age 10-12 when eye growth should normally cease. Genetics, environment and the individual’s characteristics can all contribute to this excess growth

  • In younger children, myopia progresses more quickly because their eyes are growing at a faster rate, leading to higher levels of myopia, stronger glasses and more eye health risks

  • Adult onset myopia usually occurs as an adaptation to fatigued eye focusing muscles due to a significant increase in close work, such as university studies

Why should I be concerned?

  • Myopia is becoming more common in children around the world – the prevalence among Australian 12-year-olds doubled between 2005 and 2011

  • The average age for developing myopia is reducing – younger onset means faster and more eye growth, which increases likelihood of high myopia and higher risk of eye diseases such as the following:

  • Retinal detachment – the light sensitive ‘film’ lining the back of the eye pulls away from its base, causing distorted vision or blindness depending on its location

  • Myopic macular degeneration – loss of central vision clarity, like having a thick smudge permanently in the middle of your vision

  • Glaucoma – increased pressure in the eye which damages peripheral vision, called the ‘sneak thief of sight’ as very few people who have it notice its symptoms until it is very advanced

  • Cataract – a cloudy window in the middle of the eye, like looking through a foggy windscreen

  • The average cost of glasses or contact lenses amounts over lifetime for a myopic person is likely to be in excess of $50,000. Higher myopia reduces quality of life and is more costly to correct with glasses and contact lenses

What causes myopia?

  • Spending more time on close work has been linked to development of myopia, such as reading, playing computer games, drawing or using smart phones and tablets

  • Electronic hand held devices are easy for toddlers to use resulting in increased exposure to close work at a younger age

  • Myopia can be hereditary, and a person’s ethnicity and family background can increase the risk

  • Research suggests a link between Asian ethnicity and faster progression of myopia, with higher worldwide prevalence in this group of people

  • A person with one short-sighted parent has three times the risk of developing myopia – or six times the risk if both parents are short-sighted

  • Some studies show that children are more likely to be short-sighted if their parents finished high school or went to university

  • Under or over-corrected vision (incorrect glasses, or having no glasses when they are needed) has been shown to promote onset and accelerate progression of myopia

How can I prevent or slow myopia?

  • Spending more time on close work has been linked to development of myopia, such as reading, playing computer games, drawing or using smart phones and tablets

  • Electronic hand held devices are easy for toddlers to use resulting in increased exposure to close work at a younger age

  • Myopia can be hereditary, and a person’s ethnicity and family background can increase the risk

  • Research suggests a link between Asian ethnicity and faster progression of myopia, with higher worldwide prevalence in this group of people

  • A person with one short-sighted parent has three times the risk of developing myopia – or six times the risk if both parents are short-sighted

  • Some studies show that children are more likely to be short-sighted if their parents finished high school or went to university

  • Under or over-corrected vision (incorrect glasses, or having no glasses when they are needed) has been shown to promote onset and accelerate progression of myopia

My child is already myopic!

  • Specialty contact lens designs and orthokeratology currently offer the best vision correction options to slow progression of myopia

  • Research has shown that specially designed glasses lenses are effective at slowing progression of myopia, though not to the same degree as contact lenses, and only for particular individuals with eye muscle teaming problems

  • Atropine eye drops have been shown to slow progression of myopia and their use is gaining popularity

About

My Kid's Vision is an information tool developed by optometrists Paul and Kate Gifford. While developing Myopia Profile, an online tool to assist optometrists in managing myopic patients, we recognised the need for an information source to help parents understand myopia and the steps that they can take to help their children.

Dr Kate Gifford PhD is a prominent optometrist who has been actively managing myopia for 15 years, and is recognised by her peers as a global expert in myopia and translating research to practice.

Dr Paul Gifford PhD is a contact lens researcher and developer with an adjunct position at the University of New South Wales. His research interests include the design, use of, and education in contact lenses to control progression of myopia.
