Does Material Abbe Value Influence Your Patient’s Vision?

By
In a recent Opticians Handbook article, I discussed the topic of reference wavelength. A key aspect of understanding reference wavelength dealt with differences in refraction properties of various materials for different wavelengths of visible light. Specifically, in the presence of prism, “white light” is broken up into the familiar rainbow. In general, the higher the index of the material, the more these colors are observed because of the material Abbe value.
