The human eye is an extraordinary organ, capable of adjusting to light, focusing on objects at various distances, and perceiving a vast range of colors and details. Vision begins when light enters the eye and is focused onto the retina, where signals are sent to the brain for interpretation. As we learn more about how vision develops, especially in children, myopia control has become increasingly important to manage nearsightedness and preserve long-term eye health. From the delicate structure of the cornea to the complex neural pathways involved, the process of seeing remains one of the most fascinating functions of the human body.
