O₂OPTIX is designed to help minimize the signs of corneal oxygen deficiency by delivering more oxygen to the cornea than any other traditional daily wear soft contact lens. It is a healthy choice for people who wear their lenses all day - however long that day may be. So breathable you can even nap in your lenses*
*Use only as directed by your optometrist

O₂OPTIX provides up to 5 times more oxygen transmissibility than traditional daily wear soft lenses such as Acuvue 2.

O₂OPTIX are made of a revolutionary patented silicone hydrogel material. This material consists of two phases: a silicone (ie: present in lenses such as O₂OPTIX and NIGHT & DAY^TM) and a hydrogel one (ie: present in lenses such as Acuvue 2, Focus Monthly etc). The unique molecular structure of silicone hydrogel allows water and oxygen through to the eye. The fluorosilioxane path ensures high oxygen transmissibility while the hydrogel component ensures a continuous water path for good lens movement.

What is Dk/t?

• Dk/t is the ISO (International Standards Organisation) approved measure to describe the oxygen transmissibility of contact lenses.


• Oxygen transmissibility is the rate that oxygen can flow through the lens to the eye.


• Quoted values are always for a -3.00 D lens. The Dk/t value for lenses of different powers or thickness will differ.
• Actual oxygen consumption will vary from person to person, by environment, temperature, time of day and many other factors.

How is 5 x more oxygen measured?

• This means that the Dk/t of O₂OPTIX is 5 times higher than the Dk/t of the comparative traditional daily wear soft lens.


• This means that when your eye needs it most, the lens has the ability to transmit up to five times more oxygen through the lens to the eye.

Will my eye always use 5 x more oxygen?

• A lens with higher Dk/t will always allow the eye to consume more oxygen than a lens of lower Dk/t.


• Actual oxygen consumption will vary from person to person, by environment, temperature, time of day and many other factors.


• As yet we do not have good measures of how much oxygen the cornea actually consumes and there is debate in the scientific community about how to measure and predict this.


• Traditional daily wear soft lenses (low Dk/t lenses) are associated with signs of Corneal Oxygen Deficiency but silicone hydrogel lenses (high Dk/t lenses) resolve many of these problems.
