An optical device manipulates light to achieve various effects, such as focusing, magnifying, or dispersing light. Common examples include lenses, prisms, and mirrors, which are used in applications ranging from eyeglasses and cameras to microscopes and telescopes. These devices rely on principles of optics to enhance visibility, analyze materials, or create visual displays. Overall, they play a crucial role in both scientific and everyday contexts involving light.
