Lens Materials

Although transparent – and ideally invisible – lens material is a very important component, both for your vision and your look. Typically, Hoya Vision lenses are not made of glass; instead they are made of unique plastic compositions that offer performance as well as unrivalled optical features.

The different materials have different refractive indexes. The higher the index, the thinner and lighter the lenses. In this way, optical distortions can be reduced – especially for high prescriptions. Also, reduced weight makes the glasses more comfortable to wear.
