What information do I need to order contact lenses?

Place an Order or contact Customer Service at:

1-800 LENS.COM (536-7266)

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 eye care professionals are required to provide you with a copy upon request. Be sure it contains all the necessary information, including expiration date, and is signed by your eye care professional.

Here is the information that we need:

OD = Right Eye
OS = Left Eye
Brand Name (e.g. Acuvue)
BC / Base Curve (a number between 8.0 and 10.0)
DIA / Diameter (a number between 13.0 and 15.0)
Power / Sphere / Rx (a number between -20 and +20)

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"

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. If you need more assistance please contact our Customer Service Department.
