Nearsightedness and Farsightedness
★Exhibit Content: Popular science on the principles of human eye imaging and the causes of myopia and hyperopia ★Interaction: Electromechanical interaction + multimedia demonstration ★Operation: Visitors adjust the lens curvature, eyeball axial length, and optical lenses to simulate the imaging process of normal eyes, myopic eyes, and hyperopic eyes, intuitively understand the optical principles and correction methods for different vision problems, and learn about eye health protection knowledge. ★Exhibit Overview: "Myopia and Hyperopia" is a set of popular science equipment focusing on human eye imaging and vision correction, designed for the eye health science exhibition area, and recommended by the KexMall exhibit mall. Through mechanical adjustment modules and multimedia demonstrations, the exhibit transforms abstract visual optics principles into hands-on interactive experiences, helping visitors understand how normal eyes adjust to see near and far objects through lens curvature, as well as the causes of myopia and hyperopia (such as abnormal eyeball axial length, lens curvature disorders), and learn about corresponding correction methods and daily preventive measures. ★Scientific Principle: The process of human vision formation involves external light being refracted by the cornea and lens to form a clear image on the retina, which is then transmitted to the brain via the optic nerve for processing. Normal eye: The lens can flexibly adjust its curvature to focus light on the retina; Myopic eye: The eyeball axial length is too long or the lens curvature is too large, causing light to focus in front of the retina, requiring concave lens correction; Hyperopic eye: The eyeball axial length is too short or the lens curvature is too small, causing light to focus behind the retina, requiring convex lens correction.
