Answer:
Contact lenses can focus light due to the refraction of the waves.
Step-by-step explanation:
Contact lenses utilize the principle of refraction to focus light. Refraction occurs when light waves pass through different mediums, such as air and the material of the contact lens, causing a change in their speed and direction.
In the case of contact lenses, the curvature and shape of the lens are designed to bend incoming light rays in a way that compensates for visual impairments, such as nearsightedness or farsightedness.
By altering the path of light before it reaches the eye's lens, contact lenses help to bring images into focus on the retina, facilitating clearer vision.
The ability to manipulate the refraction of light waves is a fundamental concept in optics and is effectively employed in the design and functionality of corrective lenses like contact lenses.
Thus,
Contact lenses focus light by utilizing the principle of refraction, altering the path of light waves as they pass through the lens material.
