What Is an Astigmatism Prescription and Why Does It Matter?

A prescription for astigmatism contains more detail than a typical vision prescription, because it corrects not just nearsightedness or farsightedness, but also the subtle irregularities in the shape of your eye that cause blurry, shadowed, or doubled vision. In technical terms, astigmatism is caused by the cornea or lens not being perfectly round. For most people, these differences in curvature are minor, but even small amounts can result in eye strain, trouble with night driving, and challenges when reading or using screens.

Every prescription tells a story about your unique vision. Let’s break down the main terms you’ll see and what to focus on, whether you’re considering new glasses or “glendale heights contact lenses” for astigmatism.

• OD / OS: OD is your right eye, OS is your left. These columns are the foundation of your prescription.
• SPH (Sphere): Shows whether you are nearsighted (-) or farsighted (+) and indicates the degree of correction.
• CYL (Cylinder): The number that tells us you have astigmatism. If this is zero or blank, you don’t need a toric (astigmatism-correcting) lens.
• AXIS: A value between 1 and 180 showing the angle where astigmatism occurs. This is what lets us personalize your lens to line up perfectly so you see sharp and clear.
• ADD (if present): For patients who need help with near vision—often added for multifocal lenses.

What Makes Toric Lenses Different?

Toric lenses are designed specifically to address astigmatism. Unlike standard lenses, they have varying levels of correction in different sections, and a particular orientation that must align with your eye’s unique axis. This means the accuracy of your CYL and AXIS values in your prescription has a major impact on how stable and crisp your vision will be during everyday activities.

How to Decipher Each Section of Your Astigmatism Prescription

OD and OS: Getting the Eye Right

Remember: OD = right eye, OS = left eye. Each eye could have a different correction, so double-check which column you’re looking at.

SPH: Your Overall Vision Correction

• Negative SPH values mean you are nearsighted.
• Positive values mean you are farsighted.

Example: -2.75 SPH means moderate nearsightedness.

CYL: How Much Astigmatism Correction?

• If the CYL field has a value (for example, -1.25), you need astigmatism correction.
• If it’s blank or zero, you do not.
• Larger absolute values (such as -2.00) indicate stronger astigmatic correction is required.

AXIS: The Angle of Correction

• This tells us at what meridian (from 1 to 180 degrees) your lens must compensate for astigmatism.
• This is why fit and rotation matter in toric contacts. Even a few degrees off can blur your vision, which is why precise measurement and digital equipment are so important.

ADD: For Those Who Need Help Focusing Up Close

• Typically found in multifocal or bifocal lens prescriptions (for example, if you notice trouble reading text messages or menus).
• The ADD ranges from +1.00 to +3.00 and can be paired with toric correction in both glasses and specialty contact lenses.
