Chromatic Aberration

Excerpt

Chromatic aberration, also referred to as chromatic distortion, color fringing, and spherochromatism, is a common optical phenomenon that occurs when a lens cannot bring all wavelengths of light to a single converging point. Chromatic aberration manifests as the lens's inability to focus all colors on the same axis, causing noticeable distortions or color mismatches in high-contrast scenarios. This property of light is of significant interest in optometry, ophthalmology, and medical optics, with applications and considerations ranging from lens design to diagnostic procedures.
