If you’ve ever looked at your eyeglass prescription and felt like it was written in an alien language, you’re not alone. Understanding what all those numbers and abbreviations mean is essential for ensuring your glasses meet your vision needs. At Albuquerque Vision Care and Advanced Eyewear in Albuquerque, NM, our goal is to help patients decode their prescriptions and feel confident in the glasses they choose.

Breaking Down the Basics

Most prescriptions include measurements for both eyes, labeled OD (oculus dexter, right eye) and OS (oculus sinister, left eye). Some may also include OU (oculus uterque) if instructions apply to both eyes. The numbers themselves indicate the strength of the lenses, measured in diopters. Positive numbers (+) correct farsightedness, while negative numbers (–) address nearsightedness.

Understanding Additional Notations

Beyond basic vision correction, prescriptions often include more detailed elements:

•             Cylinder (CYL) and Axis: These indicate astigmatism correction. CYL represents the lens power needed to correct the irregular curvature of the cornea, while Axis shows the orientation of the correction.

•             Add: Common in prescriptions for multifocal or progressive lenses, the Add value indicates the additional magnifying power for near tasks like reading.

•             Prism: Some prescriptions include a prism measurement to help align the eyes for better binocular vision, often used for patients with eye muscle imbalances.

Why Reading Your Prescription Matters

Understanding your prescription empowers you to make informed decisions about eyeglasses and lens options. Whether you’re selecting frames, deciding between single-vision or progressive lenses, or exploring specialty coatings, knowing what your numbers mean ensures your glasses provide the clarity and comfort you need.
