Squint (also known as strabismus) is a condition that arises because of an incorrect balance of the muscles that move the eye, faulty nerve signals to the eye muscles and focusing faults (usually long sight). If these are out of balance, the eye may turn in (converge), turn out (diverge) or sometimes turn up or down, preventing the eyes from working properly together.
Squint can occur at any age. A baby can be born with a squint or develop one soon after birth. Around five to eight per cent of children are affected by a squint or a squint-related condition, which means one or two in every group of 30 children.
If you notice your child appears to have a squint after they are six weeks old, you should have their eyes tested by an optometrist as soon as possible. Many children with squints have poor vision in the affected eye. If treatment is needed, the sooner it is started the better the results.
