We understand the importance of clarity when it comes to your eyeglass prescription. We recognize that deciphering the seemingly cryptic language of your prescription can be daunting. Fear not, for we are here to translate the process and empower you with the knowledge needed to confidently understand and interpret your prescription like a pro.
Decoding Your Eyeglass Prescription
Understanding the Basics
Your eyeglass prescription contains vital information that guides the creation of lenses tailored specifically to your vision needs. Let’s delve into the key components of your prescription:
Sphere (SPH)
The sphere, often abbreviated as SPH, indicates the primary correction needed for nearsightedness (myopia) or farsightedness (hyperopia). A negative value (-) denotes nearsightedness, while a positive value (+) signifies farsightedness.
Cylinder (CYL) and Axis
The cylinder (CYL) and axis values address astigmatism, a condition where the cornea or lens has an irregular shape. The cylinder value indicates the degree of astigmatism, while the axis denotes its orientation.
Addition (ADD)
For those with presbyopia, an age-related condition affecting near vision, the addition (ADD) value is crucial. It signifies the additional magnifying power required for reading or close-up tasks.
Prism and Base
Rarely included in standard prescriptions, prism and base values address eye alignment issues. They indicate the amount and direction of prism correction needed.
Interpreting the Numbers
Now that we’ve dissected the abbreviations, let’s put them into context:
- If your prescription reads -2.00 SPH, it means you have moderate nearsightedness.
- A prescription of +1.50 SPH indicates mild farsightedness.
- A CYL value of -1.25 with an axis of 90° suggests moderate astigmatism.
- An ADD value of +2.00 corresponds to presbyopia, requiring additional magnification for near tasks.
- Prism and base values, if present, address eye alignment issues and are specified accordingly.
