The anterior eye is the front part of the eye, which includes the cornea, iris, and lens. Synonyms for the anterior eye include the front eye, the ocular anterior segment, the anterior chamber of the eye, and the front part of the ocular globe. These terms are commonly used in ophthalmology and optometry to describe the part of the eye that is easily visible to the naked eye. The anterior eye is crucial in the process of vision, as it is responsible for regulating incoming light and directing it towards the retina, where visual information is processed. Understanding the anatomy and function of the anterior eye is essential in maintaining good eye health.
