EyeQue PDCheck, The Fastest & Easiest way to get your PD

About The EyeQue PDCheck

EyeQue PDCheck™ is the fastest and easiest way to obtain your pupillary distance (PD). Pupillary distance is the distance between your eye’s pupils in millimeters (mm). While not a medical record, PD is used for ordering eyeglasses, whether in-person or online. Without a good PD the glasses will not feel good and can cause blurriness and dizziness.

More and more people are looking for the elusive “PD” number, yet existing solutions are stuck in the 1990s. Most establishments suggest using a “printable ruler,” but this is hard to use and may result in inaccurate measurement. There are also smartphone apps that use a credit card positioned under your nose, but this not only exposes your credit card number, but it is notoriously inaccurate.

Introducing the EyeQue PDCheck. Our specially designed frames and smartphone app work together to produce accurate PD measurements that is as easy as taking a selfie (literally!) or a picture of a friend.

The PDCheck works like a charm! We’ve been giving demos all day and here are some images and videos from the show. Enjoy!

Live from CES – Real People Measuring Their PD with PDCheck

Why do I need my PD and why is it important?

Ordering eyeglasses online is becoming more and more popular – and for good reason; superior selection, low prices, and incomparable convenience. But often people are missing one critical number necessary to get a great fitting pair of glasses.  Your PD is often left off your standard prescription and is difficult to obtain yourself without proper equipment and tools.

If the PD is wrong, you will find the glasses uncomfortable, often resulting in blurry vision, dizziness, and headaches.

To clarify, you will still need an eyeglass prescription (or the like) when ordering glasses online. An eyeglass prescription is an order written by an eye doctor, such as an optometrist or ophthalmologist, that specifies the value of all parameters necessary to construct and dispense corrective lenses. PD is an element of getting great fitting glasses, but is not a medical record, nor is it required to be provided by your doctor.

A sample prescription:

Accuracy

Our patented PDCheck technology uses the smartphone camera to take a “selfie” and extracts the PD to an accuracy of +/- 1 mm.

There are mobile apps out there that have you use a credit card or paper printout held against your forehead or under your nose. These simply do not work well due to many factors including the shape of your head, and the fact that it is hard to take a selfie and hold the card in the correct position. PDCheck includes a special set of lensless eyeglass frames. The T-marks on the frames provide an accurate reference used to determine the distance between the center of your eyes. By wearing the frames, your hands are free to get a great selfie and the T-marks are near your eyes in precisely defined location. PDCheck works with both the front and rear cameras of your phone, so you can either take your own picture or have someone else take a picture for you.

Technology: How it works

The idea is simple yet robust– and easy enough for anyone to use.

The patent-pending EyeQue PDCheck Frames have three “T” marks; two near each edge and one in the center. The PDCheck mobile app uses image processing the detect the locations of the T-marks, as well as the pupils of the user.  As an added layer of accuracy assurance, once the picture is taken, the user has the opportunity to adjust the location cursors (green “+” signs), making sure that they fall on the T-marks and pupils. The result is an incredibly accurate PD measurement, rivaled only by in-person measurements at office visits.

Thinking ahead on Privacy

We take your privacy very seriously. The EyeQue PDCheck app never saves or uploads your photo image; your picture is removed as soon as we compute the relevant parameters needed for calculating an accurate PD. The PD measurement instantly displays on your mobile phone and is stored securely in the EyeQue Cloud® in your personal account – ready to be retrieved whenever you need it and accessible from desktop and mobile.

If you are using other EyeQue products, such as the Personal Vision Tracker or the EyeQue VisionCheck, the PD will automatically show up as a part of your EyeGlass Numbers.

How to use

Step 1: Download and launch the PDCheck app on any Android or iOS smartphone.

Step 2: Put on the PDCheck frames

Step 3: Take a selfie or have a friend take your picture. Make sure your face, and the PDCheck Frames, are within the oval on your phone screen.

Step 4: Make sure that the green markers are directly on the “T” marks on the frames AND on your pupils. Adjust the locations of the marks if necessary.

Step 5: Hit “confirm” and you are done! You will receive two pupillary distances: 1) your PD – the combined distance of each pupil from the center of your nose, and 2) your Near PD(reading vision, since our eyes tend to converge while focusing close-up). Access your data anywhere, anytime on your PDCheck app or by logging into your personal account at www.eyeque.com.
