What is myopia?
Myopia (short-sight) is the clinical term for when distance vision is blurred and near vision is clear.
The vision is blurry because light rays come into focus in front of the retina. This usually happens because the myopic eye grows too long.
Myopia is often considered as a mere inconvenience, given that spectacle or contact lenses are needed to see clearly. However, myopia also puts the eye at a higher risk of developing serious sight-threatening conditions such as retinal detachments and glaucoma. Globally, the number of people with myopia has increased significantly over the last decade. In the UK, this number has doubled since the 1960s, whilst in South-East Asia 80 per cent of children are myopic.
