What is myopia?
Myopia (nearsightedness) means that your child can see close up, but has problems seeing things far away. Vision problems may be classified as refractive errors or non-refractive errors. Myopia is a refractive error.
- Myopia and other refractive errors are seen in 20 percent of children.
- Myopia is the most common of the refractive error seen in children.
- It is usually not present at birth, but begins to develop as your child gets older.
What's the difference between refractive and non-refractive errors?
- refractive errors: Refractive errors occur when the eye does not focus the light that enters the eye, resulting in blurred vision.
- non-refractive errors: Non-refractive errors are caused by eye diseases.
Myopia | Symptoms & Causes
What are the symptoms of myopia?
Myopia is usually noted in children around the ages of 9 or 10. It might be discovered if your child cannot read the blackboard from the back of the room, but can see to write and read without a problem.
Other signs and symptoms may include:
- nausea after reading
- holding books close to his face
- writing with his head very close to the table
- sitting very close to the television
- squinting when looking at things that are far away
What causes refractive errors?
Refractive errors (myopia and hyperopia, or "farsightedness") have been found to cluster in families. These inherited patterns may be:
- dominant (one gene was inherited from a parent with a refractive error)
- recessive (caused by two genes, one inherited from each parent, who may or may not have a refractive error)
- multifactorial (combination of genes and environment)
Refractive errors are also present in a number of genetic disorders, such as Marfan syndrome and Down syndrome.

What treatments are available for myopia?
Eyeglasses or contact lenses may help to correct or improve myopia by helping the eye focus light.
