Chromatic aberration primarily affects what aspect of a lens?

Chromatic aberration refers to the inability of a lens to focus all colors of light to the same convergence point. This effect occurs because different wavelengths of light are refracted by varying degrees as they pass through a lens. As a result, when light of different colors passes through the lens, each color is bent at a different angle. This leads to the phenomenon where colors are separated or misaligned, particularly noticeable at the edges of images.

In practical terms, this means that when looking through a lens with chromatic aberration, you may observe color fringing around the edges of objects in the image. This can manifest as unwanted rainbow-like effects, where colors do not align properly and create a blurry or distorted appearance. Therefore, the primary aspect affected by chromatic aberration in a lens is indeed color separation at the edges, which impacts the overall image quality and sharpness.

In contrast, light absorption, uniformity of refractive power, and surface reflectivity pertain to different optical properties and do not directly relate to the phenomenon of chromatic aberration. Light absorption deals with how much light is absorbed rather than focused, refractive power uniformity ensures all light is refracted uniformly without distortion, and surface reflectivity concerns how much
