How to Convert Eyeglass Prescription to Contact Lenses: 5 Easy Steps
Meta Title: Eyeglass Prescription to Contact Lens Conversion: A Complete Guide
Meta Description: Learn how to convert your eyeglasses prescription to contact lenses safely and accurately. This comprehensive guide covers the process step-by-step, addressing common questions and misconceptions.
Do you wear glasses but are considering the convenience and freedom of contact lenses? Switching from glasses to contacts requires more than just swapping your frames for lenses. Converting your eyeglass prescription accurately is crucial for comfortable and clear vision. This detailed guide will walk you through the five easy steps of converting your eyeglass prescription to contact lenses, ensuring a safe and successful transition. We’ll demystify the process and address common concerns so you can make an informed decision about switching to contacts.
1. Understanding Your Eyeglass Prescription
Before you begin the conversion, it’s essential to fully understand the information presented on your eyeglass prescription. This typically includes several key components:
- OD (Oculus Dexter): This refers to your right eye.
- OS (Oculus Sinister): This refers to your left eye.
- Sphere (SPH): This indicates the refractive power needed to correct your nearsightedness (myopia, represented by a negative number) or farsightedness (hyperopia, represented by a positive number).
- Cylinder (CYL): This corrects astigmatism, an imperfection in the eye’s curvature. A value of 0.00 indicates no astigmatism.
- Axis (AX): This specifies the orientation of the astigmatism, expressed in degrees. Only relevant if you have astigmatism (CYL is not 0.00).
- Add: This number, if present, refers to the additional power added for near vision correction (typically for reading glasses). This is NOT usually included in contact lens prescriptions.
- Pupillary Distance (PD): This measures the distance between the centers of your pupils. This is crucial for glasses, but less so for contacts (though some practitioners still measure it).
Understanding the Differences Between Eyeglass and Contact Lens Prescriptions
While the basic components are similar, there are crucial differences. Contact lenses sit directly on the cornea, whereas glasses sit a distance away. This physical difference necessitates adjustments in the prescription, particularly for astigmatism. The power and fit of a contact lens are directly affected by the lens material and how it interacts with the tear film, requiring a more specialized assessment.
2. Scheduling an Eye Exam with an Optometrist or Ophthalmologist
This step is non-negotiable. Simply converting the numbers from your eyeglass prescription to a contact lens prescription is dangerous and could severely impact your vision. You absolutely must have a comprehensive eye exam by an eye care professional.
During this examination, the doctor will:
- Assess your corneal health: This is critical for contact lens fitting and helps determine the appropriate lens material and design.
- Determine your tear film quality: Sufficient tear production is essential for contact lens comfort. Dry eyes can make contact lenses uncomfortable or impossible to wear.
- Measure your pupil size and corneal curvature: These measurements are crucial for fitting contact lenses correctly.
Contact lenses are medical devices and require professional assessment to ensure a safe and proper fit. Attempting to self-prescribe can lead to eye infections, corneal abrasions, or other serious complications.
3. Discussing Contact Lens Options with Your Eye Doctor
Your eye doctor will discuss various contact lens options based on your prescription, lifestyle, and eye health. These options include:
- Soft contact lenses: These are the most common type, made from a soft, flexible material. They are generally comfortable and easy to wear.
- Rigid gas permeable (RGP) contact lenses: These lenses are made from a firmer material and offer sharper vision, especially for people with astigmatism or corneal irregularities. They may take longer to adapt to.
- Toric contact lenses: These lenses correct astigmatism.
- Multifocal contact lenses: These lenses correct both nearsightedness or farsightedness and presbyopia (age-related loss of near vision).
Your doctor will help you choose the best option based on your individual needs and preferences.
4. The Eye Doctor Writes Your Contact Lens Prescription
After the eye exam and discussion of your options, your eye doctor will write a contact lens prescription. This prescription will differ from your glasses prescription, and it will likely include additional information, such as:
- Base Curve: This refers to the curvature of the lens that needs to match your individual cornea shape.
- Diameter: This specifies the lens diameter.
- Lens Material: This indicates the type of material that the lenses are made of.
- Brand and model of contact lens: The optometrist will sometimes make a recommendation for specific contact lenses.
Understanding the Differences Between Your Eyeglass and Contact Lens Prescriptions: A Closer Look
The key difference lies in the base curve and diameter. These parameters ensure the lens fits comfortably and safely on your eye. Improper fit can lead to discomfort, blurry vision, infection, and damage to the cornea. This step highlights the importance of professional guidance.
5. Purchasing Your Contact Lenses and Learning Proper Care
Once you have your contact lens prescription, you can purchase your lenses from your eye doctor or a reputable online retailer. Never purchase contact lenses without a valid prescription.
Proper Contact Lens Care
Proper contact lens care is crucial for maintaining eye health. This includes:
- Washing your hands thoroughly before handling the lenses.
- Storing them in the correct solution.
- Replacing the lenses according to your doctor’s recommendations.
- Regularly cleaning and disinfecting your lens case.
FAQ: Converting Eyeglass Prescription to Contact Lenses
Q1: Can I use my eyeglasses prescription to order contact lenses online?
A1: No, absolutely not. Online retailers may ask for your eyeglass prescription, but they cannot guarantee a proper fit. A comprehensive eye exam by a licensed optometrist or ophthalmologist is mandatory before obtaining contact lenses.
Q2: Are all contact lens prescriptions the same?
A2: No. Contact lens prescriptions contain additional information (base curve, diameter, material) that eyeglass prescriptions lack. This is because contact lenses sit directly on the eye. A proper fit is essential for comfort and eye health.
Q3: How often should I replace my contact lenses?
A3: This depends on the type of lenses and your doctor’s recommendations. Some lenses are designed for daily wear and discard, while others can be worn for a few weeks or months, depending on your needs and advice from your doctor.
Q4: What are the common side effects of contact lenses?
A4: Common side effects can include dryness, irritation, redness, and occasionally, infections. Proper care and regular checkups with your eye doctor are crucial to minimize these risks.
Conclusion: Safe and Successful Conversion
Converting your eyeglass prescription to contact lenses requires a professional eye exam and proper fitting. Ignoring this step can lead to serious consequences. Remember, your eye health is paramount. By following these five steps and adhering to your eye doctor’s instructions, you can successfully transition to contact lenses and enjoy the benefits of clear, comfortable vision.

Successfully converting your eyeglass prescription to contact lenses requires careful attention to detail, and while this guide offers a simplified five-step process, remember that individual needs vary. Therefore, it’s crucial to understand that this information is for guidance only, and should not replace a comprehensive eye examination by a qualified optometrist or ophthalmologist. Ultimately, they possess the expertise to assess your specific eye health and determine the most suitable contact lenses for your vision and eye comfort. Furthermore, factors like astigmatism, corneal curvature, and the presence of dry eye syndrome significantly influence the type of contact lenses prescribed. Consequently, relying solely on online calculators or self-interpretation of your eyeglass prescription can lead to inaccurate lens parameters, potentially resulting in blurry vision, discomfort, or even eye damage. In addition to this, the base curve and diameter of the contact lens are critical and these are not usually found on a standard eyeglass prescription. Therefore, professional consultation remains paramount to guarantee a safe and effective transition. Moreover, even seemingly small discrepancies in lens parameters can impact your visual acuity and the overall comfort and health of your eyes. This underscores the importance of seeking professional guidance throughout the entire process.
Following the steps outlined in this article might provide a general understanding of the conversion process; however, it is essential to realize that the process doesn’t account for all the nuances of individual eye health. For instance, the prescription for your eyeglasses may indicate your refractive error (nearsightedness, farsightedness, or astigmatism), but it often lacks other essential data points needed for accurate contact lens fitting. Similarly, the type of contact lenses you choose – daily disposables, extended wear, toric lenses for astigmatism, or multifocal lenses for presbyopia – will influence the final parameters. In other words, your eyeglass prescription alone is insufficient for a complete contact lens prescription. Moreover, contact lenses sit directly on the surface of your eye, demanding a precise fit to avoid irritation, infection, or vision problems. As a result, a professional eye exam allows the eye care professional to assess various factors including your tear film quality, corneal health, and overall eye comfort. This comprehensive assessment minimizes the risk of complications and ensures the best possible visual outcome. Nevertheless, understanding the basic components of your prescription can empower you to engage in a more informed conversation with your ophthalmologist or optometrist.
In conclusion, while this guide offers a simplified overview of converting your eyeglass prescription to contact lenses, it’s paramount to remember that a professional consultation is indispensable. Despite the ease of access to information online, substituting professional care with self-diagnosis carries significant risks. Ultimately, the safety and health of your eyes should always be the top priority. Therefore, schedule a comprehensive eye examination with a qualified eye care professional before attempting to use contact lenses. Only they can accurately assess your individual needs and provide a suitable contact lens prescription. Remember that even minor inaccuracies in lens parameters could result in discomfort, impaired vision, or even potential damage to your eyes. Consequently, consulting a professional is not merely a recommendation, but a crucial step in ensuring proper contact lens usage and maintaining healthy vision. Lastly, prioritize your ocular health, and always seek professional guidance before making any significant changes to your vision care routine.
