What is Myopia?
Myopia, commonly known as short-sightedness is the inability to see distant objects clearly. This means that things such as television and white boards at school will be difficult to see.
In a normal eye the object focussed an image on the retina to give clear vision. Myopia occurs when the eye grow too long (axial length) or the parts of the eye which focus the light are too powerful. In a myopic eye the image is focused in front of the retina, creating blurred vision.
An estimated 5 billion people, or half the population, could be affected by short-sightedness by 2050.
