What information do I need to order contact lenses?

A contact lens prescription is made up of specific data which we require to fill your order. All of this information is available on the packaging of the contact lenses you are currently wearing, or from your optometrist or optician. In most states eyecare professionals are required to provide you with a copy upon request. Be sure it contains all the necessary information, including expiry date, and is signed by your eyecare professional.

Here is the information that we need:
OD = right eye
OS = left eye
Brand name (eg. Acuvue)
Power/Sphere/Rx (a number between -20 and +20)
Base Curve (a number between 8.0 and 10.0)
Diameter (a number between 13.0 and 15.0)

For astigmatic patients, we also need:
Cylinder (a number between -4.00 and +4.00)
Axis (a number between 0 and 180)
Cylinder and Axis are usually separated by "X" and read as "times"

Here are a few different prescription samples.

A regular prescription would look like this:

    OS Brand name:Acuvue
    OS BC:8.8 DIA:14.4 SPHERE:-2.50

    OD Brand name:Optima FW
    OD BC:8.4 DIA:14.0 SPHERE:-2.75

A prescription for astigmatism would look like this:

    OS Brand name:Acuvue Toric
    OS BC:8.8 DIA:14.4 SPHERE:-2.50
    OS CYL & AXIS:-1.25 X 180

    OD Brand name:Focus Toric
    OD BC:8.7 DIA:14.0 SPHERE:-4.50
    OD CYL & AXIS:-0.75 X 95

This information may appear complicated but in fact it is very straightforward. Just consult your current contact lens packaging for reference.
