What is myopia?

Nearsightedness (myopia) is a common condition in which a child can see clearly objects nearby but not objects in the distance, making them appear blurry. Myopia is caused by a bent or a curved lens or retina that doesn’t refract light properly. It is one of several refractive-error disorders, the other ones being hyperopia (farsightedness) and astigmatism.


  • Blurred vision when looking at distant objects
  • Squinting
  • Ablility to read a book but not read the blackboard or see images on TV
  • Eyestrain
  • Headaches


Early diagnosis is essential because a child’s academic progress can be affected by not being able to see well at a distance. Diagnosis can be made with a general eye exam, including:

  • Measurement of the pressure of fluid in the eyes
  • Refraction test, to determine the correct prescription for glasses
  • Retinal examination
  • Slit-lamp exam of the structures at the front of the eyes
  • Visual acuity test to measure vision at different distances


  • Eyeglasses
  • Contact lenses
  • Laser surgery
