Gas Permeable Material

Art Optical offers a large variety of FDA approved materials for the manufacture of GP lenses.

About GP Materials

Mid–range Dk Fluorosilicone Acrylate Materials
The lower silicone concentration and higher amount of fluorine in mid–range Dk fluorosilicone acrylate materials provides good stability and wettability without excessive weight. Thinner centers can be manufactured, while being able to hold back the same amount of corneal cylinder as lower Dk silicone acrylate materials.

High Dk Fluorosilicone Acrylate Materials
High Dk fluorosilicone acrylate materials offer a greater percentage of oxygen to the cornea without some of the wettability problems associated with high Dk silicone acrylate materials. Many patients fit in these materials report increased comfort and wettability over high Dk silicone acrylate materials.

Hyper Dk Fluorosilicone Acrylate Materials
Hyper Dk materials provide the greatest percentage of oxygen transfer available to GP lens fitting practitioners. They are ideal for patients requiring the highest possible oxygen permeability to the cornea.

Basic Dk Silicone Acrylate Materials
Basic Dk silicone acrylate materials are typically very stable lens materials used for:

Fitting high corneal astigmatism with spherical lens design
Converting long term PMMA wearers to GP lenses
Thin lens designs

High Dk Silicone Acrylate Materials
High Dk silicone acrylate materials are suitable for a wide range of patients and lens types. The higher Dk helps to increase wearing time for patients requiring greater oxygen transmission.

High Refractive Index Materials
High refractive index materials, with refractive indexes from 1.51 to 1.54, will assist in decreasing lens mass in single vision designs and can enhance the add power effect in multifocal designs.
