Strabismus is a vision disorder where both eyes do not line up in the same direction, preventing them from focusing on the same object simultaneously. It is most commonly known as "crossed eyes."

Why Does It Happen?

Each eye is controlled by six muscles that must work as a team. In strabismus, these muscles fail to cooperate. Consequently, while one eye looks straight ahead, the other eye turns inward, outward, upward, or downward.

Quick Facts:

• Symptoms: Misaligned eyes, double vision, or tilting the head to see clearly.

• Treatment: It is highly treatable through corrective glasses, eye exercises, or minor surgery to realign the muscles.
