Key points about short-sightedness in children and young people
- short-sightedness often starts in childhood
- it causes things in the distance to appear blurry
- if you think your child is short-sighted, take them to see a doctor or optometrist
- glasses and contact lenses can correct short-sightedness
- spending time outdoors and limiting close-up activities like screen time can help prevent short-sightedness
What is short-sightedness?
Short-sightedness, also called myopia, is a common condition that affects the vision and eyes. Tamariki (children) and rangatahi (young people) with short-sightedness have trouble seeing things that are far away. Things in the distance look blurry to them. Short-sightedness does not affect your child's close-up vision.
Who gets short-sightedness
Shortsightedness usually starts in childhood. It can get worse as tamariki get older. Shortsightedness tends to stabilise for most rangatahi when they reach their early twenties.
Shortsightedness runs in families. A child with one short-sighted parent has an increased chance of developing it. If both parents are short-sighted, this chance is even higher.
Causes of short-sightedness
Certain things may make tamariki and rangatahi more likely to develop short-sightedness. These include:
- having 1 or 2 short-sighted parents
- not enough time outside
- working on screens for long periods of time
- working on close-up activities such as reading and drawing for long periods of time
Symptoms of short-sightedness
Symptoms of short-sightedness include:
- blurry vision when looking at things that are far away
- squinting to try and see things better
- headaches
- rubbing eyes
- sitting closer to the television at home or the whiteboard in the classroom
- holding things closer to the face when looking at them
Signs Of Vision Or Eye Problems In Children
How to know if your child is short-sighted
If you think your child may be short-sighted, see a doctor or optometrist. An optometrist can check your child’s eyes.
Your child’s doctor may recommend visiting the hospital eye clinic to see a specialist eye doctor. Your child's doctor can refer your child to a specialist if needed.
Regular eye examinations
Regular eye examinations are the best way to find eye problems like short-sightedness.
In Aotearoa, New Zealand, there are 2 screenings that look for vision problems in pēpi (babies) and tamariki.
The first vision screening happens soon after your baby is born. The next vision screening happens when tamariki are around 4 years of age. This is part of their B4 School Check.
If a screening test picks up a problem with your child’s vision, the people running the screening program will tell you what to do next.
Treatment for short-sightedness
Short-sighted tamariki and rangatahi may need glasses to correct their vision. Rangatahi may prefer to use contact lenses for some activities. The optometrist can prescribe glasses and contact lenses for your child after their eye test.
Once your child has glasses, they will need an eye check every year. Regular eye checks help monitor for any changes to the vision. Short-sightedness can get worse with time so your child may sometimes need new glasses.
Laser therapy is not recommended for tamariki and rangatahi because their eyes are still developing.
Things to help prevent short-sightedness
Encourage your child to spend time outdoors. This can lower their chance of becoming short-sighted.
Limit the amount of time your child spends on close work. This includes reading, screen-time and playing on a smartphone. This should be no more than 3 hours a day.
