When you visit an eye care professional, you receive an eyeglass prescription that is crucial for your vision correction. But what do all those numbers and abbreviations mean? This guide will help you decode your eyeglass prescription and understand its significance.

What is an Eyeglass Prescription?

An eyeglass prescription is a written order from an eye care professional that specifies the lenses you need to correct your vision. It includes various measurements that indicate the strength of the lenses required for each eye. Understanding these measurements is essential for selecting the right eyewear.

Key Components of Your Eyeglass Prescription

Your eyeglass prescription typically contains several key components:

• Sphere (SPH): This number indicates the lens power needed to correct nearsightedness or farsightedness. A negative sign (-) denotes nearsightedness, while a positive sign (+) indicates farsightedness.
• Cylinder (CYL): This measurement is used to correct astigmatism. It shows the lens power needed to compensate for the irregular shape of the cornea.
• Axis: This number, ranging from 1 to 180, describes the orientation of astigmatism correction. It is crucial for ensuring that the lenses are positioned correctly.
• Add: This value is relevant for bifocal or multifocal lenses and indicates the additional power needed for reading or close-up work.
• PD (Pupillary Distance): This measurement is the distance between your pupils and is essential for proper lens alignment.

How to Read Your Eyeglass Prescription

Reading your eyeglass prescription can seem daunting at first. However, by breaking it down into its components, you can gain a clearer understanding. For instance, if your prescription reads:

    Right Eye (OD): -2.00 SPH, -1.00 CYL, 90 Axis    Left Eye (OS): -1.50 SPH, -0.50 CYL, 85 Axis    Add: +2.00    PD: 62

This indicates that your right eye requires a lens with a power of -2.00 for nearsightedness and -1.00 for astigmatism, while your left eye requires a slightly different correction.

Why is Your Eyeglass Prescription Important?

Your eyeglass prescription is vital for ensuring that you have the correct lenses for your vision needs. Wearing the wrong prescription can lead to discomfort, headaches, and even further vision deterioration. Therefore, it is essential to have regular eye exams and update your prescription as needed.
