The majority of children with squint are prescribed spectacles which should be worn permanently. Many need no other treatment, glasses will correct the vision and may lead to straighten the affected eye. Parents should encourage their children if they are reluctant to wear glasses.
Children who developed lazy eye (amblyopia) mostly their good eye will be patched for several hours a day to force the brain to use the lazy eye. Patching may continue for weeks or months, it improves the vision and helps the lazy eye to work.
