What is the common term used to describe strabismus?

  1. Crossed eyes

  2. Lazy eye

  3. Double vision

  4. Blurred vision

The correct answer is: Crossed eyes

The term commonly used to describe strabismus is “crossed eyes.” Strabismus refers to a condition in which the eyes do not properly align and point in different directions. This misalignment can happen in various ways, leading to one eye looking straight ahead while the other may turn inward, outward, upward, or downward. This condition may be more noticeable when a child is focusing on an object or when they are tired. While "lazy eye" is often used in conversation to describe an eye that is not being used effectively, it specifically refers to amblyopia, which can result from strabismus if not treated. "Double vision" occurs when images from both eyes do not align correctly, often a symptom of strabismus but not the same thing. "Blurred vision" can be due to various factors including refractive errors, rather than a specific misalignment of the eyes. Overall, "crossed eyes" directly corresponds to the condition of strabismus, making it the correct term.
