What vision condition can be described as ‘crossed eyes’?

The vision condition referred to as "crossed eyes" is known as strabismus. This condition occurs when the eyes do not properly align with each other when looking at an object. In strabismus, one eye may turn inward, outward, upward, or downward, while the other eye remains straight. This misalignment can be constant or intermittent and can affect depth perception and binocular vision, which is crucial for seeing the world in three dimensions.

Understanding strabismus is important in optometry as it can lead to amblyopia (lazy eye) if not addressed, particularly in children. Proper diagnosis and treatment options, such as vision therapy or corrective lenses, can help manage this condition effectively. The other options listed do not relate to the term "crossed eyes," which further underscores the specificity of strabismus as the correct answer.
