Myopia explained
Myopia is the medical term for short- sightedness, when the eyeball is too long or too powerful. The result is that light coming into the eye does not focus directly on the retina (the light sensitive layer at the back of the eye), but instead falls in front of it, causing objects in the distance to look blurred.
Myopia is traditionally corrected by wearing spectacles or contact lenses. As the eye grows, a person typically becomes more myopic and the power of their spectacle or contact lens prescription increases.
