Why the concern?
Myopia is a worldwide concern in children. In Asia more than 50 % of the young population in cities below the age of 20 are myopic. But this is also observed globally. One of the prime reasons for this increasing trend is changes in the lifestyle due to increased near work and less outdoor activities. Myopia in children is increasing at an alarming rate and could be considered as assuming pandemic proportions. -
What exactly does myopia mean?
It is near sightedness which is a form of visual impairment. When such persons look at distant objects, it appears to be blurred. As kids grow their eyes become longer. Hence the degree of myopia increases if elongation of the eyes is more than it should be at a given age. If the child’s vision system does not function properly it can affect the development adversely. If myopia is allowed to progress fast, it can affect the quality of life of the child and can even cause structural weakness of the eye thus affecting the long term vision. -
When to treat?
- Genetic – if parents are myopic, the chance increases for the child to become nearsighted.
- Environmental and lifestyle causes – excess near work, more indoor activities, lack of outdoor work, lack of natural light.
- Age of onset –myopia in children less than 7 years, increases the risk of developing high myopia.
