Accurate refractive index of the contact lenses is one of the most important parameters needed to properly evaluate the lens performance. Measurements of the refractive power and other optical properties of the lenses are typically conducted in solution, and converted to in-air performance. Such an approach is very sensitive to errors in the refractive indices of both the lens and the solution.filed under: contact lens, contact lens inspection, Non contact thickness measurement, Opthalmic
