Extreme H2O 54 is a monthly replacement lens. 54 stands for the percent of water that is combined with the ultra-hydrating material. The combination of water – with the water loving material – is what makes the lenses so comfortable. The unique hydration properties enable the lens to retain almost all of its water keeping your eyes fresh and moist all day – no matter how long the day.
Like other things we wear, the best comfort is a combination of the right material and the right fit. This is why Extreme H2O 54 comes in two sizes: 13.6 and 14.2. Multiple sizes enable your doctor to get the right size lens for your eye. This ensures a proper fit – which results in improved comfort for you.
