Pupil distance on glasses download#

After a few iterations, I had a ruler which I was happy with, we got our PD numbers, and we ordered our glasses.

Using what I had learned from our various efforts at getting an accurate PD number and noticing where the other rulers felt less user friendly, I went into Inkscape, my vector illustration program of choice, and made my own. Not satisfied with the other rulers, I decided I could take my graphic design skills and do one better. One was useful for getting a single PD reading but couldn’t help with getting a more precise value for each eye, another was meant for getting the dual PD reading (the separate value for each eye between the center of the pupil to the vertical center of the face) but it was hard to actually read the measurement and didn’t feel well positioned. I tried a couple different PD rulers, but I wasn’t completely satisfied with them. I found that online glasses providers have available PD rulers that anyone can download, print, and with the help of a friend or a mirror actually find their PD number. I was also helping a couple relatives who similarly wanted to order glasses online, and they didn’t have any information for the PD measurement on their prescriptions at all! So I needed a way to find the measurement. But I wasn’t quite sure what to enter, as I had gotten slightly conflicting numbers from different optometrists in the past. But besides entering in my vision prescription, I also needed to provide my Pupillary Distance (PD) measurement, which is the distance in millimeters between the centers of the pupils of your eyes.

Last year, I was looking for a new pair of glasses, and I decided I’d try ordering glasses online.

Sometimes this is the first part to wear away.Scroll down for printing and usage instructions. Using your existing glasses to get your current sizing: Most name brand glasses have sizing information printed on the inside of the frame or bridge. (Often the measurements do not include Vertical height) The B measurement is only important when ordering multifocal lenses. The measurements are taken from a horizontal line intersecting with the top of the lens, to the horizontal line intersecting with the bottom edge of the lens. Vertical Height (B) - refers to the vertical height of an eyeglasses lens, and is measured from the tip to the bottom of the lens aperture of the frame.Temple or Arm Size - is measured along the length of the temple, from one end to the other.It is measured between the two closest points of the two lenses. Bridge Size - measurement is the distance in millimeters between the two lenses.Width or Eye Size- refers to the horizontal width in millimeters of one of the frame's lenses.Measurements For Glasses ( eye, bridge, temple, vertical ) Normal PD for adults range from 58 to 70mm. PDs can be measured using a pupilometer or by using a ruler. PD measurements are essential for all spectacle dispensings, monocular PDs being essential in progressive lenses and for those with high prescription. This is because some peoples eyes converge when looking at near objects. PD is needed to accurately center the lens in the frame you select For bifocals or progressive lenses, some people will need a Distant Vision PD (DV PD) and a Near Vision PD (NV PD). Right eye (OD PD) and left eye (OS PD) are measured from the center of your nose to each pupil. Monocular PD is needed if your eyes are not equal distance from your nose. Pupillary Distance or PD is the distance between pupil centers of your eyes in millimeters.
