When you receive a glasses prescription, it can often feel overwhelming. However, understanding the components of your prescription is crucial for selecting the right eyewear. This guide will break down the essential elements of a glasses prescription, helping you make informed decisions about your vision care.
What is a Glasses Prescription?
A glasses prescription is a written order from an eye care professional that specifies the lenses you need to correct your vision. It includes various measurements and details that indicate the strength and type of lenses required. But what do these numbers and abbreviations mean?
Key Components of Your Glasses Prescription
- Sphere (SPH): This indicates the lens power needed to correct nearsightedness (negative numbers) or farsightedness (positive numbers).
- Cylinder (CYL): This measures the degree of astigmatism, which is an imperfection in the curvature of your eye.
- Axis: This number, ranging from 1 to 180, describes the orientation of astigmatism correction.
- Add: This is used for bifocal or multifocal lenses, indicating the additional power needed for reading.
- PD (Pupillary Distance): This measurement is the distance between your pupils and is crucial for proper lens alignment.
How to Read Your Glasses Prescription
Understanding how to read your glasses prescription can empower you when choosing new eyewear. Typically, the prescription is formatted in a table, with separate columns for each eye (OD for right eye and OS for left eye). Here’s a simple breakdown:
- Locate the SPH value for each eye.
- Check the CYL and Axis values if you have astigmatism.
- Look for the ADD value if you require multifocal lenses.
- Note your PD measurement for accurate lens fitting.
Why is Your Glasses Prescription Important?
