Nearsightedness (myopia) causes blurred vision. If you are nearsighted, you may have:

• Trouble seeing objects that are far away.
• Trouble seeing the blackboard, television, or movie screen.
• Reduced school or athletic performance.

Children younger than age 8 or 9 may not realize that they have trouble seeing objects far away. Parents or teachers may suspect nearsightedness when a child:

• Squints or frowns.
• Holds books or objects very close to the face.
• Sits at the front of a classroom or theater or close to the TV or computer.
• Is not interested in sports or other activities that require good distance vision.
• Gets headaches regularly.
