Featuring a unique chemical structure called Smart Silicone™ chemistry, these lenses (stenfilcon A) create efficient channels for oxygen delivery to the cornea. With less silicon needed to achieve the desired oxygen permeability levels, the efficient silicone network allows for increased hydrophilic materials. This results in improved lens surface wettability, higher water content and lower hydrogel-like modulus for a softer, more comfortable wearing experience. 

These lenses are the same as the Specsavers Linarial.
