About Myopia

Why is Myopia a concern for children?

Since 2000, there has been a growing trend of myopia globally. Epidemiologists have measured a global myopia rate of 22% in year 2000, growing to 30% currently and predict that by 2050, the rate of myopia globally will be 50%.

What is causing this trend?

  • Genetics and parental history.

  • High sugar diet.

    • Sugar has been shown to cause molecules in our sclera to be weak, thereby losing its resilience to the lengthening of the eyeball which characterises myopia progression.​

  • Increased near work in formal education.

    • Increased use of digital screens and technology from a young age and often poor reading posture​ or poor reading habits leads to myopia. 

    • Recommended strategies include increasing reading distance to 30 - 40cm away or elbow length, reading in good natural light, good upright reading posture. 

    • Recommended strategies of digital device usage includes limiting to 1 - 2 hours per day, and balancing 1:1 digital screen time with outdoor play time and sun exposure.

  • Time spent outdoors

    • World Health Organisation (WHO) recommends strategies devised to increase the amount of time children spend outdoors, particularly in preschool and primary school. They have recommended 2 hours per day.​


Why is Myopia a concern for children?

Myopia is associated with an increased risk of eye disease in adult life. This is a concern for our children as childhood myopia is known to be progressive until young adult life. By kerbing annual increases in myopia, we are able to significantly reduce a child's risk of eye diseases in their adult life. 

Myopia is associated with an increased risk of Posterior Subcapsular Cataracts.

Myopia is associated with an increased risk of Glaucoma.

Incidence of Myopic Maculopathy.


< -5.00 0.42%

Myopia is associated with an increased risk of Retinal Detachment.

To put these into perspective, we compare these to the risk factors of hypertension.

Systolic BP 150 - 159 2.2x

Systolic BP > 160 3.2x


Smoking as a risk factor for stroke.

By keeping a child’s prescription below -5.00, we mitigate the risk of the following conditions:

Posterior Subcapsular Cataracts -74%

Glaucoma -67%

Retinal Detachment -98%

Myopic Maculopathy -99%

Brien Holden Vision Institute published in 2016 that reducing myopia by 50% per annum will reduce the incidence of high myopia (-5.00) by 90% globally.

Our goal as eyecare professionals is to improve the quality of our children's vision and eye health for now and into the future for generations to come.
