Frequently asked questions
Will a child grow out of a squint?
Not usually. A constant squint should be checked early, because treating it in childhood protects vision and can prevent a lazy eye.
Is a new squint in an adult serious?
A sudden new squint or double vision in an adult should be assessed promptly, as it can occasionally signal a nerve or brain problem.
