Can i measure my own pd

Not everyone's eyes are the same distance apart! Getting your PD right will help your eyes focus when corrected by the glasses you wear. Use a smartphone camera or computer webcam to help calculate your PD, this can be done anywhere. While we recommend using the PD calculator, you can also do this. Just print, and you can measure your own PD.

You'll need either a tablet, phone, or laptop computer with a digital camera enabled and the volume up. Next, choose a light colored card with a magnetic strip. Go somewhere with a nice amount of light. Hold the card by the top corner, right above your eyebrows.

Using our PD calculator, you can take down your PD measurements by following the instructions. If you're not logged in, make sure to write it down.

If you have a safe ruler without sharp metal edges, you can use one at home. Or, print out our ruler. Just make sure that when you scroll through your printing settings, you use either "No scale" or "actual size" when printing. Otherwise, the measurements can get distorted. When you align the 0 on the ruler right above your right pupil trying to align it with the center of the pupil , you should be able to follow the ruler to the left eye, align it with the pupil, and read the measurement on the ruler.

Once you have a number, write it down right away so you don't forget it. Then, as you browse for glasses online, you'll know your exact PD number. One note: the ruler will give you one solid number i. In that example, you would have 32mm for each eye. Put this information in when you order your frames, and voila! Well-fitting glasses.

Pupillary distance PD is the distance measured in millimeters between the centers of your pupils. Your PD should be exact.

Your vision is centered on a small section of the lenses, so a PD number is needed to shape the lenses to perfectly suit your needs. Your PD has no effect on the size of your eyeglass frame. The PD number influences the shape of your lenses, but not the frame.

Once we reach maturity and stop growing, our pupillary distance will change very little, if at all. The PD number indicates exactly which part of the lens you look through; therefore, the PD number is important for every type of prescription lens, including single vision glasses.

Pupillary distance PD. Sounds simple right?

Many people have even had their opticians all but refuse to hand over their PD! Thankfully, the law is on your side in most states.

The Federal Trade Commission highly recommends opticians to provide their patients with their PD measurement hassle free. In some states, the law requires that they must! They must also provide you with your prescription upon request free of any fees outside of the initial exam.

Adults: Most adults will find that their pupillary distance falls somewhere between mm. Of course, you could expect most males to be on the higher side of this span mm while most females will fall somewhere between mm. The average PD distance for men is approximately 64mm while the average PD for women is right around 62mm. The averages can be used as a guide to make sure that your own PD measurement falls into a range that makes sense for your age and gender.

Of course, everyone is different so understand there is flexibility to these measurements. After all, they are just merely averages! Your PD will of course change as you grow from a child to adult, but it would take some unusual circumstances to change after puberty. In most cases, it is extremely unlikely for your PD measurement to change after you reach adulthood.

Your pupillary distance is very specific to you so a PD measuring more than a millimeter mm off can result in significant adverse side effects.
