Bausch + Lomb Boston products continue to Lead The Way In GP Technology with the introduction of our first hyper Dk gas permeable material – Boston XO2. This premium GP material offers outstanding oxygen permeability (141 Dk using the ISO/Fatt method) without compromising wettability, stability or comfort.

This new GP material combines a Hyper Dk of 141* for excellent oxygen transmissibility with the stability, wettability and performance of a lower Dk material. Boston XO2 is inherently wettable. This material has received FDA clearance for daily wear for ametropia and certain irregular corneal conditions.
