When you’re ordering prescription glasses, understanding pupillary distance (PD) is crucial for optimal vision correction. Sunnyside Vision Center in Queens, NY, explains what PD is and why it matters.
What is Pupillary Distance (PD)?
Pupillary distance (PD) is the measurement between the centers of your pupils, expressed in millimeters. It plays a critical role in ensuring that your prescription lenses are correctly centered in your eyeglass frames. Accurate PD measurement ensures that you experience clear vision through your lenses.
Why is Pupillary Distance Important?
Correct PD measurement ensures that your lenses are aligned with your eyes’ optical centers. This alignment is crucial for minimizing eye strain and maximizing visual clarity. Improper PD can lead to discomfort, headaches, and reduced effectiveness of your prescription eyewear.
How to Measure Pupillary Distance
There are two methods to measure PD:
- Standard PD Measurement: This is a general measurement used by most eyewear providers. It averages around 63mm for adults and 59mm for children.
- Exact PD Measurement: This is a precise measurement unique to each individual. It can be measured by an optometrist or through online tools with a ruler.
Factors Affecting Pupillary Distance
PD can vary due to factors such as age, prescription strength, and facial structure. For those with high prescriptions or bifocal lenses, accurate PD measurement becomes even more critical for optimal vision correction.
Ordering Glasses with the Right PD
When ordering glasses, providing your accurate PD ensures that the optical center of each lens aligns with your pupils. This alignment enhances visual comfort and effectiveness of your prescription, especially for complex prescriptions and progressive lenses.
