Short-sightedness (myopia)

Also called Myopia or Near-sightedness

Short-sightedness (myopia) is a very common eye condition that causes distant objects to look blurry, while close objects can be seen clearly. It usually starts in childhood or the teenage years and can run in families. It happens when the eye grows slightly too long, so light focuses in front of the retina.

What it is

It is usually corrected with glasses or contact lenses. Laser eye surgery is an option for some adults.

Spending time outdoors may help slow it in children. Some treatments, such as special lenses or eye drops, may slow it getting worse. High myopia raises the risk of some eye problems later in life.

Common signs

  • Difficulty seeing distant objects, such as the board at school
  • Squinting
  • Headaches or tired eyes
  • Sitting close to the TV or holding devices close

How it is usually diagnosed

  • An eye test by an optometrist

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Glasses or contact lens prescriptions over time
  • Eye test reports
  • Ophthalmology letters

Questions to ask your doctor

  • How often should my eyes or my child's eyes be tested?
  • Are there ways to slow it getting worse?
  • Am I suitable for laser surgery?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • Sudden flashes of light, new floaters or a shadow over your vision: get urgent help the same day
