Please note that a contact lens prescription is different to a standard prescription for spectacles, though these are sometimes given together. It is very common for a person to require slightly different powers for contact lenses than they do for spectacles.
A contact lens prescription contains the power, base curve (BC) and diameter (DIA) of your lenses; if you wear toric lenses, it will also contain the cylinder (CYL) and axis you require. All of this information can be found on your lens packaging as well as on your prescription.
This website is interactive, meaning you will only be offered a choice of the powers, base curves and diameters available for each particular lens. Many lenses are available in only one base curve and only one diameter, and in these cases you will be offered only one choice.
