Understanding the Eye: Anatomy, Function, and Common Diseases

The human eye is a complex organ that enables us to perceive shapes, colors, sizes, distances, and positions, allowing us to interact with our environment. This article explores the anatomy of the eye, including protective structures like the orbit, eyelids, and eyelashes, as well as transparent parts like the pupil and retina. It also delves into the eye's function of converting light into nerve impulses for the brain. Additionally, we will discuss common eye diseases, including myopia, hyperopia, and astigmatism, highlighting their effects on sight.
