You may be wondering, can you convert a contact prescription to glasses prescription? Not to worry! We'll answer your questions and help you decipher the myriad of terms and numbers associated with their prescriptions.
The answer is no, a contact lens prescription cannot be used to purchase eyeglasses, and vice versa.
To understand why the two prescription types are not interchangeable, it is essential to uncover the fundamental differences and similarities between contact and glasses prescriptions.
Let's break it down step by step.
While the corrective attributes are the same, the prescriptions themselves are not. The journey of acquiring either daily contact lenses, transition contacts, or a glasses prescription begins with an eye exam. The measurements and details captured here vary depending on the soon-to-be wearer's choice of eyewear.
This is because there are fundamental differences in how contacts and glasses interact with our eyes. For instance, glasses, designed to sit approximately 12 millimeters away from the eyes, have a different spatial relationship with the eyes compared to a contact lens, which is designed to rest directly on the eye's surface.
This proximity difference influences the strength of the prescription required for optimal vision correction.
Contact lens prescriptions often venture further, providing additional specifics like the base curve, which determines the lens's fit on the eye, and the diameter, indicating the lens's size.
Lastly, the validity of these prescriptions is a crucial aspect to consider. While it might be tempting to use a glasses prescription to order contact lenses, especially in our digital age of online shopping, it's a path fraught with pitfalls.
A glasses prescription often lacks details such as the aforementioned base curve and diameter. Using one in place of the other can lead to suboptimal vision correction and potential eye health issues.
Below are a few key similarities and differences between contact prescriptions and glasses prescriptions to keep in mind.
Sphere (SPH): Measures lens power to correct nearsightedness or farsightedness. Our findings show that the values differ between contact and glasses prescriptions due to their distance from the eye.
Cylinder (CYL) & Axis: Cylinder indicates lens power for astigmatism correction. The axis defines the lens meridian without cylinder power. If there's a cylinder value, an axis value must accompany it.
Add Power: Represents added magnifying power in multifocal lenses to correct age-related farsightedness, known as presbyopia. It's typically a "plus" power, ranging from +0.75 to +3.00 D (diopters).
Base Curve & Diameter: Specific to contact prescriptions, the base curve measures the lens's back curvature, and the diameter indicates its size.

Remember, before placing an order, it's essential to understand how to read your contact lens prescription. Based on our observations, this will help you select the correct lenses.
One common query is how long does a contacts prescription last, with most being valid for a year from the date of the eye exam.
