The lens in the human eye plays a crucial role in the process of vision. It helps focus light onto the retina, located at the back of the eye. By changing shape through a process called accommodation, the lens adjusts its curvature to control the focal length, allowing the eye to focus on objects at varying distances. This ability to refract and focus light ensures that a clear and sharp image is formed on the retina, facilitating the conversion of light signals into neural impulses. The lens, along with other components of the eye, contributes to the formation of a visual perception.

Electric heating is employed to produce light in an electric bulb through incandescence. Inside the bulb, an electric current passes through a tungsten filament. The high resistance of the filament causes it to heat up to extremely high temperatures, reaching incandescence. This intense heat emits visible light and some infrared radiation. The tungsten filament does not burn because it is enclosed in a bulb containing inert gases, usually argon, which prevents oxidation. Though incandescent bulbs are less efficient than some modern alternatives, the process of electric heating to incandescence was historically a common method for producing light in traditional light bulbs.
