Better Comfort? 3rd Generation Silicone Hydrogel Lenses. Guillon M. Are silicone hydrogel contact lenses more comfortable than hydrogel contact lenses? Silicone hydrogels: structure, properties and behaviour. When lenses dry out, they allow less oxygen to reach the cornea, for this reason silicone hydrogel lenses were introduced. Neither material types showed superiority in comfort, and adverse event rates were low with both material types. Biofinity XR toric is a cast-molded, made-to-order lens that incorporates the same uniform horizontal thickness and ballast band design as Biofinity toric.
