Do you need a PD number for single vision glasses? This is a common question for those looking to purchase glasses, and the answer may surprise you. A PD number, or pupillary distance, is a critical measurement that should be taken into consideration when buying single vision glasses. It is important to understand what a PD number is, how to measure it, and why it matters for single vision glasses. In this post, we will discuss the different types of single vision glasses, how to find your PD number, and the benefits of having your PD number. We will also answer the question of whether or not you need a PD number for single vision glasses.
What is a PD Number and How to Measure It?
When it comes to purchasing single vision glasses, one of the most important measurements to consider is the pupillary distance, or PD number. This measurement is the distance between the centers of your pupils and is necessary for your lenses to be custom fit to your eyes. To measure your PD number, you can use a ruler and stand in front of a mirror or ask someone else to help. Starting with your right eye, line up the zero end of the ruler at your pupil, and measure the distance to your left pupil. This number is your single PD number, which is usually written in millimeters.
Alternatively, you can measure your Dual PD, or Monocular PD, which is the distance between the centers of each pupil to the bridge of the nose. This measurement is usually written in two numbers, since it takes into account the distance from the center of each eye to the bridge of the nose. When ordering glasses with a Dual PD number, be sure to use “Monocular PD” when entering your measurements.
Finally, if you only have a single number available, it is possible to double this number and compare it with the frame’s PD range. With the right measurements, you can be sure that your single vision glasses will fit you perfectly.

Benefits of Having Your PD Number
Having your PD (pupillary distance) number is a great way to make sure that your single vision glasses fit perfectly. It’s the measurement between the center of one pupil to the center of the other, and it’s a crucial part of getting the right prescription. The PD number is necessary for any type of prescription glasses, but it’s especially important for single vision lenses. Here are some of the benefits of having your PD number when ordering single vision glasses:
1. Perfectly Fitting Frames: Without your PD number, it’s impossible to make sure that your frames fit your face perfectly. By having your PD number, you can make sure that the lenses are perfectly aligned with your eyes. This prevents any visual discomfort, which is especially important if you wear your glasses for long periods of time.
2. Better Vision: Your glasses won’t be able to correct your vision properly if your lenses are not aligned with your eyes. Having your PD number will ensure that your lenses are in the right position, so you can get the clearest vision possible.
3. Wider Variety of Frames: When you have your PD number, you’ll be able to choose from a wider variety of frames. Without your PD number, you’ll be limited to frames that come in a standard size. However, with your PD number, you’ll be able to choose from a wider range of frames, giving you more options for finding the perfect pair of glasses for your face and style.
Overall, having your PD number is essential for getting the right prescription and perfect fit for your single vision glasses. It’s worth taking the time to get your PD number, so you can get the best vision and comfort from your glasses.
How to Find Your PD Number
To better understand your specific needs when buying single vision glasses, let’s look at the next steps of how to find your PD number.
How to Ensure You Get the Right Prescription for Single Vision Glasses
Getting the right prescription for single vision glasses is essential for your long-term eye health and vision. It is important to purchase your glasses from a quality source that is familiar with the proper measurements and prescriptions for single vision glasses. Additionally, you will need to get a PD number from your eye doctor.
A PD number, or pupillary distance, is the distance between the centers of each of your pupils. This measurement is an important factor in determining the correct prescription for your single vision glasses, as it helps ensure that the lenses are properly aligned with your eyes.
Your eye doctor will be able to measure your PD number and provide you with a copy of the measurement. Make sure to bring the PD number with you when you purchase your glasses, as this will help ensure that you get the right prescription. Additionally, make sure to check with your doctor to ensure that your prescription is within the correct range for single vision glasses.
By taking these simple steps, you can be sure that your single vision glasses provide the best protection and style. With the correct prescription, you can be sure that your vision will stay clear and sharp for years to come.
How to Read Your Prescription for Single Vision Glasses
If you’re looking for single vision glasses, you’ll need to know how to read your prescription. This can help you understand the different numbers and abbreviations on the prescription, as well as the correct lens type for you.
The first thing to know is that single vision glasses are designed to correct nearsightedness, farsightedness, and astigmatisms. The ‘ADD’ column will be blank for single vision prescriptions, as this is used for bifocal and progressive lenses.
Your prescription will include a number of numbers and abbreviations. These include the sphere (SPH) and cylinder (CYL) power, which are measured in diopters (D). If a correction is needed for astigmatism, the cylinder power will be noted. The axis (AX) indicates the direction of the astigmatism, measured in degrees (°).
It’s also important to note that the prescription for contacts is different than for glasses. For example, the patient will need to provide a ‘PD’ (pupillary distance) number for glasses, which indicates the distance between the pupils. This is usually between 54-74mm.
To illustrate, here’s an example of a single vision reader prescription: Right SPH: +2.50, CYL: -1.50, AX: 60°; Left SPH: +2.50, CYL: -1.50, AX: 60°.
By understanding how to read your prescription, you can choose the right single vision lens type for you. It’s always important to ensure that your prescription is up to date and accurate, as this will ensure you get the best possible vision correction.
What to Look for When Shopping for Single Vision Glasses
When shopping for single vision glasses, there are several factors to consider to ensure you get the best possible product for your needs. The most important factor is to determine the correct pupillary distance (PD) number. This number will ensure that the lenses are centered in the frame and that the prescription is accurate.
In addition to the PD number, shoppers should also consider the lens type, frame selection, and price. It is important to select a frame that is comfortable, fits well, and is of high quality. There are various lens types available such as single vision, bifocal, and progressive lenses, and it is important to select the type that best fits the individual’s needs.
When shopping for single vision glasses, it is also important to pay attention to the prices of the frames and lenses on the website. Online retailers often offer discounts and promotions on designer frames and prescription lenses, so it is beneficial to compare prices between different retailers.
Finally, shoppers should determine if a single-vision lens or a progressive lens is better for their individual needs. Progressive lenses offer a more natural progression of vision, allowing the wearer to see in both near and far distance. However, single-vision lenses are less expensive and easier to adjust to.
By following these tips, shoppers can ensure that they are getting the best possible product to meet their needs. It is important to take the time to find the right frame and lens type, as well as to determine the correct PD number. By doing so, shoppers can ensure that their single vision glasses are of the highest quality and provide the best possible vision correction.
Why PD Number Accuracy Matters for Single Vision Glasses
When ordering single vision glasses, it is important to ensure that the PD (pupillary distance) number is as accurate as possible. This number is used to ensure that the lenses are aligned correctly in the frame, providing the wearer with the clearest vision possible.
When measuring the PD, it is important to ensure that it is done correctly. The traditional method of measuring PD is binocular, which is done with both eyes open. However, this method can lead to inaccurate measurements, as the two eyes may not line up exactly. The more accurate way to measure PD is monocular, which is one eye at a time measured from the center of the pupil to the center of the bridge of the nose.
Having an accurate PD number can also be helpful when ordering progressive lenses. Progressive lenses are used to correct multiple vision issues, and having an accurate PD measurement can help ensure that the lenses are correctly aligned in the frame.
For those ordering glasses online, it is important to make sure that the PD number is taken correctly. Some sites may require a photograph of the wearer with their PD measurement visible. Additionally, many sites may require both a single PD and dual PD to ensure accuracy.
It is important to note that there is no ‘normal’ PD range, as everyone’s eyes are different. Therefore, it is important to make sure that the PD number is as accurate as possible when ordering glasses. Having an accurate PD number can go a long way in helping ensure that your glasses are comfortable and provide the clearest vision possible.
Conclusion
In conclusion, PD numbers are important for single vision glasses as they ensure that your glasses are the correct prescription. Knowing your PD number can also help you choose the right frame for your glasses and make sure you get the best vision possible. When shopping for single vision glasses, make sure to check your prescription and PD number to ensure you get the right pair of glasses.
