Understanding your glasses prescription is key to ensuring you get the right lenses for your visual needs. Your prescription typically includes various parameters such as SPH, CYL, Axis, ADD, and Pupillary Distance (PD). At Lenses Direct, we're here to demystify these numbers and guide you through their significance.
Breaking Down Your Glasses Prescription:
- OD and OS: These abbreviations denote your right eye (OD) and left eye (OS) respectively, outlining each eye's specific requirements.
- SPH (Sphere): SPH indicates the lens power needed for near-sightedness (denoted by a minus sign) or far-sightedness (denoted by a plus sign), measured in dioptres.
- CYL & AXIS: CYL represents the cylindrical power needed to correct astigmatism, while AXIS specifies the orientation of the cylindrical power, measured in degrees from 0 to 180.
- ADD: ADD refers to the magnifying power required for reading or multifocal lenses, aiding in close-up vision. This value is typically the same for both eyes.
- Prism: If needed, prism measurements (BO, BU, BI, BD) may be included to address eye alignment issues. If this is included in your prescription please use the message function to notify us.

Understanding Pupillary Distance (PD):
Your PD measures the distance between the centres of your pupils and is vital for accurate lens placement. It ensures that the optical centres of your lenses align perfectly with your pupils, optimizing vision clarity and comfort.
How to Read Your Glasses Prescription:
- A minus sign (-) indicates near-sightedness, while a plus sign (+) indicates farsightedness.
- The "Add" power signifies the need for magnifying lenses, such as reading glasses or progressives, for close-up vision.
