"Ocular" refers to anything related to the eyes or vision. It is derived from the Latin word "oculus," meaning eye. This term is often used in medical contexts, such as in ocular diseases or ocular anatomy, to describe conditions or structures associated with the eyes. In addition to its medical usage, "ocular" can also pertain to visual perception in general. For example, ocular dominance refers to the preference of one eye over the other in visual processing. Understanding ocular functions is essential for fields like optometry and ophthalmology, which focus on eye health and vision care.
