How to read my contact lens prescription?

Different doctors have different formats for the scripts they use when prescribing contact lenses to you, but some of the information will always be the same. You will always find the following on your prescription form:

• Your name
• The examination date
• Expiration date
• Prescriber information
• Power (PH)
• Manufacturer/brand and/or material
• Base curve (BC)
• Diameter (DIA)
• Additional prescription info such as cylinder (CYL) and
axis values may appear as well.
