Chromatic aberration

Chromatic aberration is a visual distortion that occurs when a lens fails to focus all colors of light at the same point. This happens because different wavelengths of light bend at slightly different angles when they pass through a lens. As a result, images can appear blurry or show colored edges, especially around high-contrast areas. Common in cameras and telescopes, chromatic aberration can be minimized with specially designed lenses or software. Understanding this effect is essential for improving image quality in photography and optics.
