Lazy Eye and Squint
About 2 or 3% of children have a lazy eye, medically known as amblyopia. This may be because they have one eye that is much more short- or long-sighted than the other, and the two eyes do not appear to work together.
It is more difficult to treat a lazy eye after the eyesight has finished developing which is usually around the age of seven, so early detection is important. However, it may still be possible to improve the vision in the weaker eye.
If the child has a lazy eye, using eye drops in the other eye, or wearing a patch over the other eye, can help them to use the lazy eye to make it see better. Also, wearing glasses may improve their sight.


Squint
A squint, also called strabismus, is where the eyes point in different directions. It’s particularly common in young children, but can happen at any age. One of the eyes may turn in, out, up or down while the other eye looks ahead. If you notice your child appears to have a squint after they are six weeks old, you should have their eyes examined by an Optometrist as soon as possible.
The sooner a child has treatment, the more likely they are to have good vision. If the child has a squint, this may be fully or partially corrected with glasses. However, some children may need an operation to straighten the eyes. This can be done as early as a few months of age.
