VSP Optics Introduces New Digital Progressive

VSP Optics Group will add a new digital, N category progressive to its line of Unity Performance Optics. It is called Unity PLxpression with Cascade Technology.The lens will reportedly offer the wearer:

• Optimized viewing zones through variable base curve technology.

• Improved cosmetics with thinner, flatter lenses.
