Materials & coatings

Lens design and lens coating do different jobs

The optics inside the lens and the treatment on its surface work together, but they answer different questions.

Design arranges optical power. A coating treats the surface. Neither can replace the other.

Start with the optical design

The lens design determines how prescription power is arranged. A progressive design, for example, places distance, intermediate and near viewing areas within one lens. A single-vision design serves one prescribed visual purpose.

The right design is chosen with the prescription, intended tasks and fitting requirements in mind. This decision comes before comparing surface finishes.

THE IDEA, SIMPLY

Optics first. Surface second.

Lens design

Where and how the prescription power works across the lens.

Surface treatment

How the lens surface handles reflections, care or appearance.

Then consider the surface

An anti-reflective treatment reduces reflections from the lens surface. Other layers may address scratch resistance, cleanability, water or oil repellence, tint or appearance. The actual stack and measured results depend on the selected product.

A coating cannot create a progressive viewing zone, and a progressive design cannot deliver the surface properties of a coating. They can be selected together when the material and product range allow it.

A better question at the dispensing desk

VisuLuxe is a progressive design family; GlamAR is an anti-reflective coating family. Ask which design serves the visual routine, which material suits the prescription and which compatible finish meets the wearer’s needs.

For any coating, request its care guidance and warranty terms. A before-and-after image is useful only when the lighting, product and whether the result is illustrative or measured are clear.

Questions worth asking

  • What is the lens design meant to do?
  • Which coatings work with this material and prescription?
  • What care and warranty terms apply?
