ULTRA is a soft contact lens family, and we carry four of its six packs. Between them they cover the four situations most prescriptions fall into, which makes the range easy to navigate once you know which one you were written for.
You do not really choose here, your prescription does. Look at what your eye doctor wrote. A cylinder and an axis value point to the astigmatism lens. An add value points to the presbyopia lens. Both together point to the multifocal toric. Neither points to the standard spherical lens.
A six pack holds six lenses, so most people need one box per eye. If your two eyes have different powers, base curves or diameters, they are separate boxes rather than one shared order.
Contact lenses are prescription medical devices in the United States. You will need a current prescription from your eye doctor, and we will ask for the values on it, including power, base curve and diameter, plus cylinder, axis or add where they apply. If your prescription has expired, or the lens on it is not one of these, book an appointment first rather than ordering the closest match.
