Squint is also known as strabismus or crossed eye. It is a condition in which the eyes get misaligned. In simple terms, both the eyes point towards different directions, and each eye focuses on a different object.
The affected eye may point downward, upward, leftward, or rightward.
This may happen because of the disorder in the brain or when the muscles that control eye movement are not able to work together.
