Web28. dec 2024 · Chromatic aberration is a type of image defect due to the fact that different wavelengths of light have different refractive indices. In almost all sources I read so far, this type of optical aberration is discussed only with respect to lenses. The following text is from this webpage:. For many years, chromatic abberation was a sufficiently serious problem … Web17. jan 2024 · Refraction is measured in dioptres (D) which describes the power that a structure has to focus parallel rays of light (ie bring them to a point) The higher this value, the stronger the focusing ability. In the eye, refraction happens mainly at the surface of the cornea and at the surface of the lens.
