What Material Is Precision1 Made From and What Makes Verofilcon A Different?

Precision1 is made from Verofilcon A — a proprietary silicone hydrogel developed by Alcon specifically for this lens. Understanding Verofilcon A explains how Precision1 delivers oxygen, maintains comfort, and what differentiates it from other daily silicone hydrogel lenses.

What Is Verofilcon A?

Verofilcon A is a silicone hydrogel material with a moderate core water content (around 51%), an integrated SMARTSURFACE® outer layer exceeding 80% water content, a Dk/t of approximately 100 supporting healthy corneal oxygenation, a lens diameter of 14.2mm and base curve of 8.3mm.

Why Silicone Hydrogel Matters

Silicone hydrogel materials allow oxygen to pass directly through the lens matrix — independent of water content. This is the critical advantage over traditional hydrogel materials, which rely on dissolved oxygen in the lens water content. Verofilcon A's silicone structure delivers oxygen efficiently even at moderate core water content.

What Makes Verofilcon A Different

The distinguishing feature of Verofilcon A is the SMARTSURFACE® Technology integrated into its outer layer. Most silicone hydrogels are naturally hydrophobic at the surface and require either a coating or wetting agent to create comfort. Verofilcon A instead creates a structurally distinct, high-moisture outer layer that is part of the material itself — giving Precision1 lenses their specific comfort profile: stable oxygen performance from the core, hydrated comfort from the surface.

Note: Alcon's UV blocking figures for Precision1 (approximately 90% UVA / 99% UVB) should be verified with Alcon's current product documentation before relying on them for clinical specifications.
