Myopia: Nearsightedness, the ability to see closer objects more clearly than distant objects. Myopia can be caused by an elongation of the eyeball or by any condition that prevents light rays from focusing on the retina.
Myopia has become an epidemic that is impossible to ignore. According to a study published in the Journal of Ophthalmology, it is predicted that half the world’s population will be myopic by 2050, with up to 1/5 of them at a significantly increased risk of blindness if current rates continue.
Degrees of Myopia
Myopia is generally classified according to the degree of myopia, that is the power of the prescription lens required to correct the blurred vision, measured in dioptres (D).
Low myopia: -1.00 to -3.00
Moderate myopia: -3.00 to -6.00
High myopia: -6.00 and above
According to World Health Organization (WHO), the definition of high myopia is “a condition in which the spherical equivalent objective refractive error is ≤–5.00 D in either eye”.
Risks of Myopia
Are you and your husband both wearing glasses? What are the risks for your child to develop high myopia?
A normal eye length is 22 to 24 mm. The risk for the child to suffer from vision impairment when they grow older is high if the eyeball grows longer than 26 mm.
Myopia Control is about slowing down this excessive eye growth to the ideal normal rate of eye growth in childhood.
The table below shows the risks of eye diseases according to the degree of myopia when your child ages.
Squinting when watching TV, whiteboard at school
Sitting in close proximity to the TV/computer screen/books
Needing to sit in front of the classroom to see clearly
Seems disinterest in doing homework / sports
Yes, amongst other factors as well. Eg: lifestyle and reading habit
As soon as possible.
The core of visual hygiene is the 20-20-20 rule. For every 20 minutes of near activity, we should take a 20 second break and look at objects 20 feet away.
To completely stop the progression is pretty much impossible, especially if the child is still growing. We can control the progression of the myopia and slow it down.

Yes, it does. Blue light protection lenses help to filter out the harmful blue light from entering your eyes.
We cannot prevent myopia from happening, but we can control the progression of it with good visual hygiene together with one of the myopia control methods.
Yes, depending also on the prescription.
Eye rubbing is mostly associated with astigmatism, but in some instances can have an effect on myopia as well.
Myopia is not a dangerous vision condition, but it does increase the risk of your child to develop serious vision later in life. Eye diseases associated with high myopia include glaucoma, cataract, retinal detachment and myopic macular degeneration.
