A two year study revealed that key physiological measures related to lens comfort improved significantly when people switched from their current contact lens brand to ACUVUE^® OASYS™ Brand Contact Lenses.

HYDRACLEAR^® Plus technology mixes the wetting agent into the lens formula itself, making them feel so smooth and slick, you'll barely know they're there.

Lenses with HYDRACLEAR^® Plus wetting technology are better than other brands at mimicking the naturally smooth way your tears cover the surface of your eye. That means you get a feeling that's almost like you're not wearing lenses at all.

Wettability Lenses with HYDRACLEAR^® wetting technology are better than a leading brand at mimicking the naturally smooth way your tears cover the surface of your eye. That means you get all-day moisture, for all-day comfort.

LACREON™ technology creates a cushion of moisture that stays right where you want it. The result is 47% less friction and more moisture that won't blink away so your eyelids will glide comfortably over the lens all day.

Some lens makers just add a wetting agent to the packing solution so when you blink over the course of the day, a little bit gets wiped away. LACREON™ technology mixes the wetting agent into the lens formula itself. It won't blink away over time, giving you a fresh lens feeling at the end of the day.

Unlike ballast designs that have a single zone of stability at the bottom of lenses, Accelerated Stabilization Design (ASD) uses four zones of stability to help keep lenses right where they need to be.

A clinical study showed that lenses with Accelerated Stabilization Design (ASD) maintained orientation almost 3 times better than two leading lenses with a ballast design at a 90 degree head position. That means in situations such as lying down to watch your favorite show, your vision can be more consistent and clear.

Advanced eye-tracking technology has shown that lenses with Accelerated Stabilization Design (ASD) are more stable and have less rotation than a leading lens with a ballast design. The result is consistently clearer vision, from scanning text on a computer screen to playing ball with your buddies.

A clinical study versus two leading brands concluded that lenses with Accelerated Stabilization Design (ASD) provided greater stability when people look in many directions. As you can see, the lens with ASD rotates less than ballast lenses when looking in many different directions. So no matter if you move your eyes up, down, from side to side, or somewhere in-between, your vision can be consistent and clear.

Depth of field is the portion of an object or scene that appears in focus. As you can see, when you focus close up, the background is not in focus. And when you focus far away the foreground is not in focus. STEREO PRECISION TECHNOLOGY™ works with this natural function of the eye to provide balanced vision near, far, and in-between.

Dk, or oxygen permeability, is the rate that oxygen can flow through a contact lens. Dk/t, or oxygen transmissibility, determines how much oxygen gets through a lens of a particular thickness. As you can see, these leading silicone hydrogel contact lens brands all allow nearly 100% of available oxygen to get to the eye.

Contact lenses that offer high levels of protection against UV rays are labeled as either Class I or Class II. Class I lenses block at least 90% of UVA and 99% of UVB rays while Class II block at least 70% of UVA and 95% of UVB rays. All ACUVUE^® OASYS™ Brand and ACUVUE^® ADVANCE^® Brand lenses are classified as Class I while all other ACUVUE^® Brands are classified as Class II. ACUVUE^® Brand is the only brand that offers UV protection across its entire line of products.
