Have you ever wondered about the benefits of your spectacle prescription? Your eyeglasses help you see clearly. They also improve your overall eye health and reduce strain.
Understanding the advantages of your prescription can help you make informed decisions about your eye care. Let’s delve into the world of spectacle prescriptions. Let’s uncover how they can benefit you.
Understanding Your Eye Prescription
OD and OS
In eye prescriptions, “OD” means “right eye” (oculus dexter), and “OS” means “left eye” (oculus sinister). Measurements can vary between the two eyes, such as Sphere, Cylinder, and Axis values. The Cylinder value shows the type of astigmatism correction needed, with positive and negative values indicating different types. The Axis value indicates the orientation of the astigmatism correction along the eye’s meridians.
Understanding both OD and OS values is important for providing the right visual correction. Eye doctors use these values to prescribe suitable lens power in diopters for nearsightedness, farsightedness, or presbyopia. Knowing the prismatic power for base in or base out corrections can reduce eye strain and ensure clear vision with glasses or contacts. Regular eye exams and consultations with optometrists at SSM Health are important for maintaining proper vision correction and overall eye care.
Sphere, Cylinder, and Axis
Eye prescriptions consist of the terms “Sphere, Cylinder, and Axis.” These terms represent lens power, astigmatism correction, and orientation of the astigmatism.
During an eye exam, the eye doctor determines these values for suitable visual correction. The Sphere value corrects nearsightedness or farsightedness.
The Cylinder value corrects astigmatism by addressing blurred vision from irregular eye curvature.
The Axis value specifies the astigmatism correction’s orientation along meridians. These are usually the vertical and horizontal lines of the eye.
Incorporating these values into lenses can help individuals achieve clear vision and alleviate common vision problems. Regular eye exams are important to ensure up-to-date prescriptions, especially for conditions like astigmatism and presbyopia.
Reading Addition
Reading Addition, also known as near addition, is a value added to an eye prescription to address presbyopia, a common age-related condition that affects the eye’s ability to focus on near objects.
This component impacts the lens power required for reading glasses by adjusting the prescription for close-up tasks such as reading or using electronic devices.
Reading Addition values can vary among individuals due to factors like age and overall eye health.
Accurately assessing this component during an eye exam is important.
Determining the correct Reading Addition ensures suitable visual correction for individuals experiencing presbyopia, enhancing their ability to see up close clearly.
Regular eye exams and consultation with an eye doctor are important to monitor changes in Reading Addition.
This helps ensure that the eye prescription is up-to-date and meets the individual’s needs for clear vision and eye care.
Common Vision Problems
Common vision problems are myopia, hyperopia, and astigmatism. These issues affect how clearly a person can see due to errors in the eye’s shape. Symptoms include blurred vision, headaches, and eye strain. An eye doctor uses a prescription chart and protractor scale to measure lens power and meridians. This helps determine the right lenses for glasses or contacts. For specific issues like astigmatism, additional measurements for cylinder, axis, and prismatic power may be needed.
Regular eye exams are important for detecting and treating vision problems early. Choosing reputable eye care providers like SSM Health can help effectively address these common vision issues.

Interpreting Your Eye Prescription Chart
Sphere (SPH)
The sphere (SPH) in an eye prescription chart helps correct nearsightedness or farsightedness. It is measured in diopters and is necessary for clear vision.
SPH impacts vision clarity and focus when using eyeglasses or contact lenses.
Compared to Cylinder (CYL) and Axis, SPH corrects overall vision blur caused by common problems like astigmatism. CYL, on the other hand, fixes corneal or lens curvature irregularities causing astigmatism.
The Axis in the prescription chart determines the orientation of the correction for astigmatism, focusing on different eye meridians.
Eye doctors need to understand the relationship between SPH, CYL, and Axis to prescribe the right lenses for clear vision.
Regular eye exams are vital to monitor changes in the prescription and address visual impairments accurately.
Cylinder (CYL)
The Cylinder measurement in an eye prescription shows the power needed to correct astigmatism. Astigmatism is when the eye can’t focus light evenly on the retina, causing blurry or distorted vision.
The Cylinder value specifies the extra lens power required to fix the affected meridians of the eye due to astigmatism. It could be in the horizontal or vertical meridian. Measured in diopters, this value is important in giving the right visual correction for people with astigmatism.
Eye doctors accurately determine the Cylinder value during a thorough eye exam. This ensures that eyeglasses or contact lenses are made precisely to match the unique eye shape and give clear vision.
