When light strikes a spectacle lens, it is broken and dispersed into its component parts. This creates a disruptive visible colour spectrum, similar to a prism. The intensity of this effect, known as dispersion, depends on the condition of the material used: high-quality material = minimal dispersion.
The advantage of natural glass: It produces considerably weaker colour fringes even when the refractive index is identical to that of plastic lenses.
The result: Even when the refraction index is the same, spectacle lenses made of glass are always thinner than those made of plastic .
