What is the purpose of an antireflective coating?

• A. To increase the durability of lenses
• B. To change the color perception of light
• C. To reduce reflections on the surface of lenses
• D. To enhance the magnification of images

Answer: (C)

The purpose of an antireflective coating is primarily to reduce reflections on the surface of lenses. This coating works by minimizing glare and enhancing light transmission through the lens, which allows for clearer and more accurate vision. In optical devices such as glasses, cameras, and microscopes, the presence of reflections can distort images and hinder visibility. By applying an antireflective coating, less light is lost due to reflection, resulting in improved image quality and a more comfortable viewing experience. While options related to increasing durability, altering color perception, or enhancing magnification may address other aspects of optics, they do not capture the fundamental role of an antireflective coating, which is focused on minimizing unwanted reflections.
