Air Optix is a family of contact lenses sold in six lens boxes, and the five options on this page differ mainly in what they correct. Which one is yours is not really a shopping decision: the lens name, the parameters and the replacement schedule are all set by the doctor who fitted you.
A contact lens is a prescribed medical device in the United States, so we verify a current, valid prescription before an order ships. Have yours to hand when you order. It lists the brand, the power for each eye, a base curve and a diameter, and for toric and multifocal lenses a cylinder, an axis or an add value too. If it has expired, an eye examination is how it gets renewed.
Work from your replacement schedule. Buying several boxes at once is usually cheaper per lens, and it means you are not reordering in a hurry the week a lens tears. Lenses in this range are not interchangeable even where the names look similar, so any change from one to another is a conversation with your eye care professional rather than a swap at the cart.
