Myopia, or nearsightedness, is a common condition in which a child can see objects nearby but not in the distance, making them appear blurry. Symptoms often develop during the school years. Myopia is caused by a lens or cornea that doesn’t refract light properly. It is one of several refractive-error disorders, the other ones being hyperopia (farsightedness) and astigmatism.

Honor Society of Nursing (STTI) answeredMyopia is the medical term for nearsightedness. Myopia can occur in anyone at any age. Typically, diagnosis also includes the type or time of onset, such as youth, early, or late adult onset. In myopia, you have difficulty seeing things clearly at a distance, while things close are clear. Myopia is correctable, and may be mild or severe, beginning slowly or quickly.
If you're able to see objects up close better than those that are far away, you may be nearsighted, a condition called myopia. The problem happens when light focuses in front of your retina instead of on it, making faraway objects look blurry. Glasses, contacts, or laser surgery may help you focus better.
Laura Fine, MD, Ophthalmology, answeredA person with myopia (nearsightedness) has difficulty seeing objects at a distance because the light rays converge and focus before reaching the retina. The cause is usually an elongated eyeball (which requires light rays to travel farther than they would in a normal eye), or a lens or cornea that is too strong, bending the light rays so they focus before getting to the retina (the innermost layer of the eye).
