What is Galyfilcon A and why does it matter in Infuse One-Day lenses?

What Is Galyfilcon A? The Material Behind Bausch + Lomb Infuse One-Day

The material a contact lens is made from determines almost everything about its performance — oxygen permeability, moisture retention, comfort, and suitability for different wearers. Infuse One-Day lenses are made from Galyfilcon A.

What Is Galyfilcon A?

Galyfilcon A is a silicone hydrogel material developed by Bausch + Lomb specifically for the Infuse One-Day lens, combining:

• • 55% water content — relatively high for a silicone hydrogel material, contributing to a soft, natural feel
• • High oxygen transmissibility — silicone hydrogel allows significantly more oxygen to pass through the lens to the cornea than traditional hydrogel materials
• • Soft, flexible construction — designed to conform gently to the eye's surface for comfortable fit from first insertion

Why Silicone Hydrogel Matters

Silicone hydrogel materials allow oxygen to pass directly through the silicone matrix of the lens — independent of water content. This means Galyfilcon A maintains high oxygen delivery even as the lens loses some moisture during the wear day. Galyfilcon A provides the structural and oxygen performance platform, while ProBalance Technology handles surface comfort and ocular environment support.
