It helps clinicians estimate whether one eye is turned in, out, up, or down compared with the other. It is commonly used in routine eye exams, pediatric eye care, and strabismus (eye misalignment) evaluations. It is often performed when a person cannot reliably perform more complex alignment tests."}
