Optics in Everyday Life: Glasses, Cameras, and Lenses

Optics is the study of how light behaves when it reflects, refracts, or bends.
Glasses correct vision by bending light so it focuses properly on the retina.
Convex lenses help people with farsightedness, while concave lenses correct nearsightedness.
Cameras use lenses to focus light onto sensors, forming sharp images.
Zoom lenses change focal length, bringing far objects closer or widening the view.
Microscopes and telescopes use multiple lenses to magnify tiny or distant objects.
Optical coatings reduce glare and improve clarity in glasses and camera lenses.
Smartphone cameras use miniature lens systems with advanced optics.
Contact lenses work like glasses but sit directly on the eye.
From eyeglasses to photography, optics shapes how we see the world.
