Kids can be born with squint or may develop it in childhood. Often, it's caused by a problem with the muscles that move the eyes, and can run in families.
Most kids with squint are diagnosed when they're between 1 and 4 years old.
Most kids with squint don't complain of eye problems or don’t notice changes in their vision. Usually, it's a family member, teacher or health care provider who notices that the eyes are not straight.
Some kids may complain of double vision (seeing two objects when there's only one in view) or have trouble seeing things in general.
These problems also can affect reading skills and classroom learning. Younger kids who aren't talking yet may squint a lot and turn or tilt their heads in an attempt to see more clearly .
