While the blurred vision associated with myopia can be “corrected” by glasses or contacts, the actual cause of myopia is increased growth of the eye itself. For clear vision, light should come to a focus point directly onto the back of the eye at the retina. In myopia, the eye is longer than usual, resulting in a focus point that falls in front of the retina, causing distant objects to appear blurry, while close objects can be seen normally.
The increased eye growth that results in myopia is influenced by several factors. The likelihood of children developing myopia increases if their parents are myopic. There is also an increased risk for children who spend more time indoors, and more time focusing on near tasks such as reading books or digital devices.
