If you’ve ever looked at your glasses or contact lens prescription and wondered what the numbers mean, you’re not alone. For those with myopia—commonly known as nearsightedness—understanding your prescription is key to managing your vision effectively. Myopia prescriptions are designed to correct blurred distance vision, ensuring that you can see clearly, whether you’re driving, watching TV, or enjoying the view in Alexandria.
At Nova Eye Care Center, our experienced eye doctors specialize in diagnosing and managing myopia for patients of all ages. In this article, we’ll break down what your myopia prescription means, how it works to improve your vision, and the advanced techniques available to manage progressive myopia. Whether you’re navigating a new prescription or exploring options to control myopia, this guide is here to help you make informed decisions about your eye health.
What Does a Myopia Prescription Mean?
Your myopia prescription is more than just numbers—it’s a detailed map of how your lenses correct nearsightedness. Understanding its components can help you better manage your vision and communicate effectively with your eye doctor.
Key Elements of a Myopia Prescription
SPH (Sphere):
Indicates the strength of the lens needed to correct your vision, measured in diopters (D).
Negative numbers (e.g., -2.50): Represent the degree of nearsightedness, with larger negative values indicating stronger correction.
CYL (Cylinder):
Corrects astigmatism, if present, by addressing an uneven curvature in your eye that causes blurred or distorted vision.
If there’s no astigmatism, this field will typically be blank.
Axis:
Works with CYL to pinpoint the orientation of the astigmatism correction in your lenses.
Measured in degrees (0 to 180), it tells the lens manufacturer where to place the correction.
Examples of a Myopia Prescription
SPH -2.00 CYL -0.75 Axis 90: A typical prescription for mild nearsightedness with moderate astigmatism.
SPH -4.50 CYL blank Axis blank: A stronger myopia correction without astigmatism.
Understanding these elements ensures you know how your lenses work to bring distant objects into sharp focus.
At Nova Eye Care Center in Alexandria, we take the time to explain each part of your prescription during your exam. Our goal is to ensure that your glasses or contact lenses are precisely tailored to your vision needs, helping you see clearly and confidently in every situation.
How Myopia Affects Your Vision
Myopia, or nearsightedness, occurs when your eye shape causes light to focus in front of the retina instead of directly on it. This results in distant objects appearing blurry while nearby objects remain clear. Whether it’s recognizing a friend across the street or reading road signs, myopia can significantly impact daily activities.
Symptoms of Myopia
Blurred Distance Vision: Difficulty seeing objects far away, such as a whiteboard or TV screen.
Eye Strain: Frequent squinting or discomfort while focusing on distant objects.
Headaches: Often caused by overworking your eyes to compensate for blurred vision.
Difficulty Seeing at Night: Myopia can exacerbate night vision issues, making driving in low light challenging.
What Causes Myopia?
Myopia can develop due to a combination of genetic and environmental factors:
Genetics: If one or both parents are nearsighted, the likelihood of developing myopia increases.
Lifestyle Factors: Prolonged near-vision activities, like reading or screen time, can contribute to its progression, especially in children.
Eye Shape: An elongated eyeball or overly curved cornea disrupts how light focuses on the retina.
At Nova Eye Care Center in Alexandria, our skilled eye doctors conduct comprehensive exams to assess how myopia affects your vision and provide customized solutions. Whether it’s glasses, contact lenses, or advanced management techniques, we’re here to help you see your best every day.
Correcting Myopia with Glasses and Contact Lenses
For most people with myopia, glasses or contact lenses provide an effective and convenient way to achieve clear vision. These corrective lenses work by refocusing light directly onto the retina, compensating for the eye’s inability to focus on distant objects.
How Glasses Correct Myopia
Glasses for myopia feature lenses with a negative diopter (SPH) value, which helps redirect light so it focuses correctly on the retina.
They’re available in a variety of designs, including lightweight, thin lenses for higher prescriptions, ensuring both comfort and clarity.
Contact Lenses for Myopia
Soft Contact Lenses: Flexible and comfortable, ideal for daily or extended wear.
Rigid Gas Permeable (RGP) Lenses: Provide sharper vision and are effective for high myopia or irregular corneas.
Daily Disposable Lenses: A great option for convenience and hygiene, particularly for busy lifestyles.
Choosing Between Glasses and Contacts
Your choice depends on lifestyle preferences and vision needs:
Glasses are low-maintenance and suitable for all ages.
Contacts offer a wider field of vision and are ideal for active individuals or those who prefer a glasses-free look.
At Nova Eye Care Center in Alexandria, our experienced eye doctors can help you decide which option best suits your lifestyle. We also provide personalized fittings for both glasses and contact lenses to ensure optimal vision correction and comfort. Whether you’re exploring new options or updating your current prescription, we’re here to help you see clearly and confidently.
Advanced Myopia Management Techniques
While glasses and contact lenses correct myopia, advanced management techniques can help slow its progression, especially in children and young adults. These innovative options are designed to protect your vision long-term and reduce the risks associated with high myopia.
Orthokeratology (Ortho-K)
Ortho-K involves wearing specially designed rigid gas-permeable contact lenses overnight. These lenses gently reshape the cornea, temporarily correcting myopia so you can enjoy clear vision during the day without the need for glasses or daytime contacts. Ortho-K is particularly effective for managing myopia progression in children.
Atropine Eye Drops
Low-dose atropine eye drops are a proven method for slowing myopia progression. These drops relax the eye’s focusing mechanism, reducing strain and helping to prevent further elongation of the eyeball.
Multifocal Contact Lenses
Multifocal contact lenses are traditionally used to correct presbyopia but are also effective for controlling myopia progression. They provide clear vision at various distances while helping to slow the progression of nearsightedness.
Lifestyle Adjustments
Encouraging outdoor activities and limiting prolonged screen time or near-work tasks can also play a role in reducing myopia progression. Natural light exposure is thought to benefit eye health, particularly in children.
Myopia Control for Children and Teens
Since myopia often develops during childhood, early intervention is critical. Combining treatments like Ortho-K or atropine drops with regular eye exams can significantly reduce myopia progression and improve long-term eye health.
At Nova Eye Care Center in Alexandria, our dedicated eye doctors offer comprehensive myopia management plans tailored to your specific needs. Whether it’s innovative treatments like Ortho-K or lifestyle recommendations, we’re committed to helping you and your family protect your vision for years to come.

Risks of High Myopia
While mild and moderate myopia are generally manageable with glasses or contact lenses, high myopia—characterized by prescriptions stronger than -6.00 diopters—can pose additional risks to your eye health. These risks make proactive management and regular eye care essential.
What Is High Myopia?
High myopia occurs when the eyeball is significantly elongated, causing light to focus far in front of the retina. This can lead to more severe vision issues and potential complications over time.
Complications Associated with High Myopia
Retinal Detachment:
The stretched retina in high myopia is more prone to tears or detachment, which can cause vision loss if not treated promptly.
Myopic Macular Degeneration:
Over time, the excessive elongation of the eye can damage the central retina (macula), leading to blurry or distorted central vision.
Glaucoma:
High myopia increases the risk of developing glaucoma, a condition that damages the optic nerve due to elevated eye pressure.
Cataracts:
Individuals with high myopia are at a greater risk of developing cataracts earlier in life.
The Importance of Regular Eye Exams
Routine eye exams are critical for monitoring the progression of high myopia and detecting early signs of these complications. Early diagnosis and treatment can significantly reduce the risk of permanent vision damage.
At Nova Eye Care Center in Alexandria, our expert eye doctors provide advanced monitoring and management for high myopia. From routine check-ups to customized treatment plans, we’re here to help you protect your vision and maintain optimal eye health.

When to See an Eye Doctor
Regular eye exams are essential for managing myopia and ensuring your prescription remains accurate. However, there are specific signs and situations that indicate it’s time to visit your eye doctor for an evaluation.
Difficulty Seeing Clearly
If you’re struggling to see distant objects, even with your current glasses or contacts, your prescription may need updating. Blurred vision is a common sign that your myopia has progressed.
Frequent Headaches or Eye Strain
Uncorrected or under-corrected myopia can cause headaches and discomfort, especially after extended screen time or reading.
Worsening Night Vision
If driving at night becomes more challenging or you notice halos around lights, it’s time to have your prescription and eye health checked.
Sudden Vision Changes
Rapid changes in vision, flashes of light, or floaters could indicate a serious issue, such as retinal detachment, which requires immediate attention.
Children and Teens with Myopia
Children’s vision can change rapidly, so it’s important to schedule annual exams to monitor progression. Myopia management techniques like Ortho-K or atropine drops can help slow the progression effectively.
At Nova Eye Care Center in Alexandria, our experienced eye doctors provide thorough evaluations to assess your myopia and update your prescription as needed. Whether you’re noticing symptoms or simply due for your annual exam, we’re here to help you maintain clear, healthy vision. Schedule your visit today to stay on top of your myopia care.
FAQs About Myopia Prescriptions
What do the numbers on my myopia prescription mean?
The numbers represent the strength of the lens correction needed for your vision. A negative SPH value indicates nearsightedness, with larger negative numbers requiring stronger correction to focus distant objects clearly.
Is a high myopia prescription dangerous?
While high myopia itself is manageable, it increases the risk of complications like retinal detachment, macular degeneration, and glaucoma. Regular check-ups with an eye doctor are essential to monitor and manage these risks.
Can myopia progression be stopped?
While myopia can’t be completely stopped, its progression can be slowed with advanced techniques like Orthokeratology (Ortho-K), atropine eye drops, or multifocal contact lenses. These treatments are especially effective for children and teens.
How often should I update my myopia prescription?
It’s recommended to have an eye exam at least once a year to ensure your prescription is accurate. If you notice blurred vision or eye strain, schedule a visit sooner to address any changes.
Are glasses or contacts better for high myopia?
Both options work well, but contact lenses may offer a wider field of vision and better comfort for high prescriptions. Specialized options like Ortho-K or high-index glasses lenses are also available for managing high myopia effectively.
