Are children's eye problems genetic?
Many eye problems have a genetic tendency: short-sightedness, astigmatism, long-sightedness or lazy eye in the family make them more likely in a child. Every child should still be examined, even with no family history.
Eye problems can run in families
An eye problem in a parent or a more distant relative can be passed on to a child through genes. Sometimes, even when both parents are healthy, a problem seen in a cousin can also appear in the child.
Which family problems matter?
- Short-sightedness (myopia): High myopia in the family can make myopia start earlier and progress in a child. For these children we can give advice aimed at slowing its progression.
- Astigmatism: If it runs in the family, a child is quite likely to have it too. Astigmatism cannot be prevented, but it is corrected with glasses.
- Long-sightedness and lazy eye: With a family history, the child is checked more often; early diagnosis can often prevent squint and lazy eye.
An eye check is needed even with no family history
Eye conditions can also occur in children with no family history of eye problems. For this reason, every child should have regular eye examinations.

Can astigmatism be prevented?
No, it cannot be prevented. However, it is corrected with glasses so the child can see clearly.
What should we do if lazy eye runs in the family?
The child should be examined at an early age and checked more often.
