Part of Speech: Noun

Explanation:

"Optical aberration" refers to a problem that occurs when a lens or mirror does not focus light correctly, leading to a blurry or distorted image. This can happen in cameras, glasses, telescopes, and other devices that use lenses or mirrors to see or capture images.

Usage Instructions:

Advanced Usage:

In more advanced discussions, you might talk about different types of optical aberrations, such as: - Chromatic aberration: This occurs when different colors of light do not meet at the same point after passing through a lens, resulting in color fringes. - Spherical aberration: This happens when light rays that strike a lens or mirror near its edges focus at a different point than rays that strike closer to the center.

Word Variants:
