Do Eye Doctors Have to Give You Your PD? Understanding Your Right to Your Pupillary Distance
Yes, eye doctors are generally required to provide your pupillary distance (PD) after an eye exam, as this is considered part of your prescription information. Understanding your rights ensures you can get accurately fitting eyewear from any vendor.
What is Pupillary Distance (PD) and Why Does It Matter?
Pupillary distance (PD) is the measurement of the distance between the centers of your pupils. This crucial measurement ensures that the lenses of your glasses are correctly positioned in front of your eyes. Accurate PD ensures optimal vision, reduces eye strain, and prevents headaches. Without it, your lenses may not focus light correctly, leading to visual distortion. Knowing Do Eye Doctors Have to Give You Your PD? is vital to getting the right glasses.
The Benefits of Knowing Your PD
Having your PD opens up several advantages:
- Online Eyewear Purchases: Allows you to buy glasses online with confidence, often at lower prices.
- Shopping Around: Enables you to compare prices and styles at various retailers without being locked into your eye doctor’s selection.
- Accurate Lens Centration: Ensures your lenses are properly aligned for optimal vision correction and comfort.
- Future Reference: Having it documented simplifies future eyewear purchases.
How Eye Doctors Measure PD
Eye doctors typically measure PD during your eye exam using one of the following methods:
- Pupillometer: A specialized instrument designed to precisely measure the distance between pupils. This is the most common and accurate method.
- Manual Measurement: Using a ruler marked in millimeters, the doctor measures the distance between the pupils while you focus on a distant object. This method is less precise but generally sufficient.
The measurement is usually recorded in millimeters (mm). You might see it as a single number (binocular PD) or as two numbers (monocular PD), representing the distance from the center of each pupil to the bridge of your nose. Both values are vital for accurate lens fitting.
Legal and Ethical Considerations: Are Eye Doctors Obligated?
While specific regulations vary by location, many jurisdictions consider PD to be a part of your prescription information. Ethically, most eye doctors understand their responsibility to provide this information. Generally, withholding PD information is considered unethical and anti-competitive, restricting your ability to purchase eyewear from other sources. Knowing Do Eye Doctors Have to Give You Your PD? protects your right to choose.
What to Do If Your Eye Doctor Refuses to Provide Your PD
If your eye doctor refuses to give you your PD, consider these steps:
- Politely Ask Again: Remind them that you require the information for purchasing glasses elsewhere.
- Cite Regulations (If Applicable): Research local regulations regarding patient access to prescription information.
- Contact the State Board of Optometry: Report the refusal to the relevant regulatory body. This can encourage the doctor to comply.
- Seek a Second Opinion: Obtain an eye exam from a different doctor who will provide your PD.
- Consider an Online PD Measurement Tool: While not as accurate, some online tools can provide an estimated PD. Always verify with a professional where possible.
Potential Challenges and How to Overcome Them
Sometimes, you might encounter challenges in obtaining your PD:
- Office Policy: Some offices may have a policy of not providing PD, often due to perceived concerns about online eyewear quality. Politely explain your need for the information and, if necessary, escalate to the practice manager.
- Extra Charge: Some doctors might try to charge an extra fee for providing your PD. This is generally considered unethical, especially if you’ve already paid for a comprehensive eye exam. Refuse the charge and consider reporting it.
- Inaccurate Measurement: If you suspect your PD is inaccurate, request a re-measurement during your appointment or seek a second opinion.

Frequently Asked Questions (FAQs)
Is it legal for an eye doctor to refuse to give me my PD?
Generally, no. While specific laws vary by state, most jurisdictions consider PD to be part of your prescription, and you have a right to access your complete prescription information. Refusal could be a violation of patient rights and ethics. It’s crucial to know your rights when wondering, Do Eye Doctors Have to Give You Your PD?
Can an eye doctor charge me extra for my PD measurement?
Charging an extra fee solely for your PD measurement, especially if it was already measured during your eye exam, is generally considered unethical and, in some cases, illegal. It should be included as part of the overall comprehensive eye exam fee.
What if my eye doctor says they don’t have my PD on file?
If your eye doctor claims they don’t have your PD on file, it’s worth asking if they measured it during the exam. If they did, they should provide it. If they didn’t measure it, you may need to request another, brief measurement. Insist politely as knowing Do Eye Doctors Have to Give You Your PD? is important.
Is an online PD measurement as accurate as a professional measurement?
Online PD measurement tools can provide an estimate, but they are generally not as accurate as a professional measurement by an eye doctor or optician. For the best results, always opt for a professional measurement.
Why do some eye doctors seem hesitant to give out PD information?
Some eye doctors might be hesitant due to concerns about patients purchasing glasses online, where they might not receive the same level of fitting and adjustment as they would in a traditional optical shop. However, patients have the right to choose where they purchase their eyewear.
What is the difference between binocular PD and monocular PD?
Binocular PD is the total distance between your pupils, measured in millimeters. Monocular PD, on the other hand, is the distance from the center of each pupil to the bridge of your nose. Monocular PD provides a more precise measurement for lens centration.
Can I measure my own PD at home?
You can attempt to measure your own PD at home using a ruler and a mirror, but the results are unlikely to be as accurate as a professional measurement. It is best to have a professional determine your PD for the most accurate results.
What happens if my PD is not accurate in my glasses prescription?
If your PD is not accurate in your glasses prescription, you may experience eye strain, headaches, blurred vision, or even double vision. It’s crucial to ensure your PD is accurate for comfortable and effective vision correction.
How often should I get my PD checked?
You typically only need to have your PD checked during your eye exam when you get a new glasses prescription. Adults’ PD usually remains stable, while children’s PD may change as they grow.
What should I do if my eye doctor says PD is “proprietary information”?
If an eye doctor claims your PD is “proprietary information,” this is incorrect and potentially unethical. Your PD is part of your prescription and you have a right to it. Insist on receiving the information or report the issue to the state board of optometry.
Does PD change over time?
PD generally doesn’t change significantly in adults. However, it can change in children and adolescents as their faces grow. Regular eye exams are important to monitor for any changes.
Where else can I get my PD measured if my eye doctor refuses?
If your eye doctor refuses to provide your PD, you can try getting it measured at another eye doctor’s office, a standalone optical shop, or even some online retailers that offer in-person measurement services. Ensure they are using accurate measuring equipment.
