OD is an abbreviation for the Latin term oculus dexter which means right eye. Notice that the right eye information is asked for first even though we typically read from left to right.
OS is an abbreviation of the Latin oculus sinister which means left eye. That will be referenced on the far right column of the prescription.
SPH is short for sphere. The sphere of your prescription indicates the power on the lenses that is needed to see clearly. A plus (+) symbol indicates the eyeglass wearer is farsighted. A minus (-) symbol indicates that the eyeglass wearer is nearsighted.
CYL is short for cylinder. The cylinder indicates the lens power necessary to correct astigmatism. If the column has no value (is blank), it indicates that the eyeglass wearer does not have astigmatism. If this is the case on your prescription, you can leave it blank when entering it in.
AXIS is a prescription will include an axis value for those with astigmatism. This number represents the angle of the lens that shouldn't feature a cylinder power to help correct your astigmatism.
ADD is short for "additional correction." This is where details about bifocals, multifocal lenses or progressive lenses would appear.

B.C. is short for base curve measurement indicates the back curvature of your contact lens, in millimetres. This is important for comfort, as the BC of your contact lenses should match your eye's natural curve as closely as possible to ensure a better fit when you are wearing your contact lenses.

As of February 4th 2004, a law called "The Fairness to Contact Lens Consumers" act went into effect.
It states that your eye doctor must release your prescription to you on completion of your contact lens fitting, and that we must verify that you have a valid prescription in order to be able to ship your order.
We DO NOT need to have a copy of your prescription
You can provide us with your doctor's name and phone (or preferably fax) number, and we can contact them to verify your prescription.
** If the doctor's office does not respond to our verification request within 8 business hours, we are required to assume that your contact lens prescription is valid and can begin to process your order.
If you have your prescription handy, you can fax or email it to us to expedite your order. If we receive a fax or scan of your rx, your doctor will not be contacted unless there is a discrepency with your prescription that we need to clear up.
