When it comes to selecting the right eyewear, understanding your prescription from glasses is crucial. This guide aims to demystify the components of your prescription, helping you make informed choices about your vision care.
What is a Glasses Prescription?
A glasses prescription is a detailed document provided by an eye care professional that outlines the specific lenses you need to correct your vision. It includes various measurements and terms that can be confusing at first. So, what exactly does it entail?
- Spherical (SPH): This indicates the degree of nearsightedness or farsightedness.
- Cylindrical (CYL): This measures astigmatism, which is an irregular curvature of the eye.
- Axis: This is the orientation of astigmatism correction, measured in degrees.
- Add: This is the additional magnifying power needed for reading, often included in bifocal or multifocal prescriptions.
Decoding Your Prescription
Understanding the numbers on your prescription can feel overwhelming. However, breaking it down can simplify the process. For instance, if your prescription reads -2.00 SPH, this indicates that you are nearsighted and require a lens that is -2.00 diopters. Conversely, a +2.00 SPH would indicate farsightedness.
Moreover, if your prescription includes a CYL value, it signifies that you have astigmatism. The axis value will help your optician align the lenses correctly. If you have questions about these terms, don't hesitate to ask your eye care professional for clarification.
Choosing the Right Lenses
Once you understand your prescription from glasses, the next step is selecting the appropriate lenses. Various lens options are available, including:
- Single Vision: Ideal for correcting one field of vision, either distance or near.
- Bifocal: These lenses have two distinct optical powers for distance and near vision.
- Progressive: These provide a gradual transition between multiple vision zones without visible lines.
Each type of lens has its advantages, so consider your lifestyle and visual needs when making a choice. For more information on lens options, visit

Regular Eye Exams and Updates
It is essential to have regular eye exams to ensure your prescription from glasses remains accurate. Vision can change over time, and an outdated prescription can lead to discomfort or vision problems. How often should you get your eyes checked? Generally, adults should have an eye exam every one to two years, but this can vary based on individual needs.
In conclusion, understanding your glasses prescription is vital for maintaining optimal vision. By familiarizing yourself with the terminology and options available, you can make informed decisions about your eyewear. Remember, your eye health is important, so don’t hesitate to seek professional advice when needed.
