Technology Overview

Manufacturers design contact lenses based on diverse combinations of material formulas, as well as more than 10 structural and chemical features. These combinations create lenses that are unique and proprietary to each manufacturer’s brand, and designed to suit different patient needs.

Today, doctors have more than 160 brands of contact lenses to choose from when navigating their patients’ unique needs. Contact lenses’ Class II/III medical device classification from the Food and Drug Administration (FDA) provides doctors and patients with confidence in their lenses’ safety and effectiveness, even as more combinations are discovered.
