Caring for young eyes

Most very young children have their eyesight assessed as part of routine developmental checks. While these are very important, they aren’t as thorough as a complete eye test by a qualified optician. So we recommend that your child has their eyes tested from an early age.

Testing before your son or daughter goes into full-time education means that any problems that they may have are identified early, setting them up for a happy and fulfilling school life. That’s because not being able to see clearly can be confusing in a busy classroom.

Poor eyesight can cause learning and behavioural problems, which might be blamed on other things. This is especially true for young children, who may find it difficult to explain the difficulties they are having with their eyesight. They may not even be aware they have a problem at all.

And of course the sooner that vision problems are detected, the better the outcome. Conditions such as squint and amblyopia (lazy eye) can be treated more effectively if they are picked up earlier, which could make a huge difference to your child.

Screen time for kids: impacts and advice

Common eye conditions


What is a Squint?

A squint is a condition where the child’s eyes point in different directions. It can cause blurred vision, double vision and lead to lazy eye.

How common is it?

Around 1 in 20 children have a squint. It usually appears before the age of five and is picked up in routine eye checks.

How is it treated?

Squints can be treated with glasses and eye exercises. If these don’t work, surgery may be needed to move the muscles that control the eye.


What is an Astigmatism?

Astigmatism is a minor eye condition that causes blurred or distorted vision. It occurs when the cornea or lens isn't a perfectly curved shape (more like a rugby ball than a football).

How common is it?

It is very common. In fact, many people who wear glasses will have some degree of astigmatism.

How is it treated?

Left untreated, astigmatism can cause headaches, eye strain and tiredness, particularly after doing tasks that involve focusing on something for long periods, such as reading or using a computer. In most cases astigmatism is easily corrected with glasses or contact lenses.


What is Short-sightedness?

Being short-sighted means that you can focus on objects when they are close up, but those further away will be blurred.

How common is it?

Very. About one in three people are short-sighted. The condition is usually first diagnosed at around the age of 12, but young children can also have it.

How is it treated?

In children, short-sightedness is easily corrected with glasses.

Amblyopia or lazy eye

What is Amblyopia or lazy eye?

If your child is diagnosed with an amblyopic or lazy eye, it usually means that one of their eyes is weaker than the other, causing them to rely more on their ‘good’ eye.

How common is it?

Around 1 in 50 children develop an amblyopic or lazy eye. It can usually be diagnosed at about the age of four during routine eye checks with a qualified optician, or at their developmental screening.

How is it treated?

Glasses will be prescribed to correct the vision in the weaker eye and often no further treatment is required. If the weak eye does not respond fully then a patch can be worn over the good eye for part of the day to force the weaker eye to work. Treatment is usually effective but may take a while.


What is Long-sightedness?

Children who are long-sighted find it easier to focus on things which are further away than those which are close to them. Long-sighted children may experience blurred vision or tired eyes when reading.

How common is it?

Most children are slightly long-sighted but often will not require glasses to correct it unless it is causing a problem.

How is it treated?

If your child has a significant amount of long sight, it can be corrected with glasses.

Things to look out for

It’s often difficult to tell whether your child has sight problems, which is why regular eye tests are so important. There are a number of things to look out for:

  • Straining their eyes or tilting their head to see better
  • Frequent eye rubbing
  • Losing their place while reading, or using a finger to guide their eyes
  • Sensitivity to light and/or excessive tearing
