A: There is a vast array of glass types for an optical designer to choose from to achieve the best possible performance in a new lens design. Different glass types can affect lens performance and design by influencing factors like optical clarity, refractive index, and dispersion. For instance, selecting a high-refractive-index material, such as flint glass, allows you to create thinner, lighter lenses for a given power. The downside of flint glass lenses is that they have higher dispersion leading to chromatic aberration.
