Myopia Frequently Asked Questions


What is high myopia?

High myopia is also named as pathological myopia, usually defined as the spherical equivalent of greater than 5.00 diopters. Pathological myopia is generally progressive and presents very early in childhood.


How does a child develop myopia?

Myopia occurs when the eyeball becomes too long, therefore, incoming light rays focus at a point in front of the retina rather than directly on the retina surface, which causes distance objects to appear blurry.


Is my child at risk of developing myopia?

Children whose parents have pathological myopia are more likely to develop myopia. Myopia is often diagnosed in children between 5 and 12 years of age and may continuously become worse during the teen years.


When should I take my child to see an optometrist?

When children notice their distance vision decreases, some children may tell their parents; but many won’t. Your child may have myopia if he or she squints or frowns when watching TV, gets headaches often after reading, or likes to watch TV at a very close distance. The child may not be interested in sports or other activities that require good distance vision. These indicate that it is time to take your child to see an optometrist.


What causes myopia?

Pathological myopia is predominantly caused by genetic factors. Children inherit the tendency to develop the eye condition from their high myopic parents. Additionally, how the children use their eyes, for instance, constant performing close-up tasks, may also have an influence on the development of myopia.


Is myopia preventable?

Although it is not completely preventable, there are steps you can take to minimize myopia occurring.

Scientists suggest that a minimum 2 hours of outdoor activities can help to hinder the onset of myopia.


Can myopia be improved by using eye exercises?

It is quite the opposite as a matter of fact. The myopic eyes are in need of relaxation instead of “exercise”. When eyes are looking at the distance objects, they are at rest.


Would myopic children’s vision get worse year after year?

Generally, myopia progresses year after year throughout the adolescent growth period. As myopia gets worse, the vision gets worse as well. Their vision usually stabilizes as they become adults.


Why should we care about myopia control?

In people with myopia, especially with high myopia, the eyeball stretches and becomes too long. This can lead to holes or tears in the retina and even result in retinal detachment. Abnormal blood vessels may also grow under the retina and cause vision to deteriorate. High myopia also increases the risk of developing other vision threatening pathological conditions such as cataracts, glaucoma and macular degeneration etc.
