How Does a Pupilometer Work?
A pupilometer is a medical device that measures the distance between the centers of each pupil—also called “pupillary distance”—through visual stimuli. It is used for fitting eyeglasses to make sure that the lenses are centered in the visual axis.
Usually associated with eye doctors, a pupilometer can also be a device for anyone who simply does not want the hassle—and added costs—of going to an eye clinic. Customers will now be able to measure their own pupillary distance (PD) and order their glasses online.
The pupilometer will tell the manufacturer of the glasses where to put the optical center on each lens. Therefore, ensuring accuracy with the measurement of the PD is very important for the glasses to fit clearly. And getting the right pupilometer that does this must be done with caution.
So if you are thinking of buying a pupilometer for you but don’t know how to do it right, then you have come to the right place. Continue reading to find out…
What Should I Consider Before Buying a Pupilometer?
Let us first talk about the basics. When buying a pupilometer, it helps to consider the following to ensure that the product works best for you:
- Consider how pupilometers are handheld instruments. Therefore, size and weight are relative to buying it. Make sure that it is not too large or too heavy to be used. It has to fit right through your hands and be light enough for it to be comfortable to use.
- Distance is important. So make sure that the pupilometer you are buying can cover a range of pupillary distances. This is to ensure that the device won’t be inadequate in giving you the measurements.
- Easy to use. The pupilometer is a device used to make the job of measuring pupillary distance easier. So acquiring the measurement shouldn’t be hard and must not require a person with a background on optometry for it to be understood. With that, make sure the pupilometer is very easy to use and friendly to all users.
Why is a Pupilometer Important?
Now as part of the buyer’s guide, it is important that you know why buying a pupilometer is important for you. And no, it goes beyond being a convenient device.
As we have mentioned, pupilometer is used to measure the pupillary distance. With this lies its true purpose.
When shopping for glasses online, you will need to ensure that the measurements you provide are accurate—including the pupillary distance. The pupillary distance ensures that the prescription glasses you have are focused well according to your pupils. You may fall as having “Average PD”, which falls between 60 mm and 66 mm, or outside it. So for this, you will need an accurate measurement.
However, doing that may seem like you have to visit an optician for them to provide the measurements. But that is not the case anymore. With the pupilometer, you can now get the pupilometer distance measurements and order the prescriptions within the comforts of your home.
And we are here to help you find the best pupilometers out there. How did we do it? Read on to find out…

1. Sunwin Optical Digital Pupillary Distance Meter SC252 – Editor’s Pick
What rose above all of the competition is the Sunwin Optical Digital Pupillary Distance Meter model SC252. This device provided us with an accurate reading of the pupillary distance while being very easy to use. Also, the features are great bonuses.
First is the physical aspect. The device has a size measurement of 25cm x 13.8cm x 5.5cm and a weight of 715g. This evidently made it very comfortable to use. It is not too heavy nor too big.
Next is the device itself. It has the capacity to measure pupillary distances that range from 48 mm to 77 mm. The resolution is 0.5mm with a viewing distance that is from 35 cm to infinity.
This digital pupilometer provides precise optical structure and measurement and a very clear line of light. It has a direct PD adjustment lever and an adjustable viewing distance selecting lever.

2. Gizmo Supply Digital LCD Optical Pupilometer – The Stylish Runner-Up
Probably out of all the pupilometer devices that we found, the Gizmo Supply Digital LCD Optical Pupilometer has the sleekest appearance. This we love because not only does it work, it is also stylish.
The size measurements are 9.4 x 13.7 x 4.1 inches with a weight of 2.1 lbs. Like the rest, this tells us that the device is handy enough to use.
Going deeper, we have to identify the range of measurements the Gizmo Supply Pupilometer can accommodate. The binocular pupillary distance ranges from 45mm to 80mm. Its lef or right pupillary distance can go from 22.5 mm to 40 mm. Lastly, its distance of target begins at 30 cm.
The measurement results are of course displayed digitally. The left and right eye measurements are displayed separately.
For its other features, the pupillary device has an auto power off once the measuring operation is completed. It also has a memory function that enables you to save the data.
Another thing that we like about this is that it can be used in monocular mode. This means that you can actually use it to measure just one of either your left or right eye in case you want to repeat reading.
If there were anything that we want it to improve on would be its manual. It is hard to read and follow.
This makes the device appear hard to use than it actually is.

3. Sunwin Digital Pd Meters Digital Pupilometer SC344 – The Effective Runner-Up
Following from the same brand is the Sunwin Digital PD Pupilometer model SC344. It offers almost the same features and efficiency; making it a close competition with the one above.
Its physical size is 221mm(L) x 164mm(W) x 63mm(H) and weighs 1.6 pounds. Making it a very handy size.
The Sunwin Pupilometer SC344 also has a great effective range of measurements. Its binocular pupillary distance ranges from 45-82mm; the left or right pupillary distance from 22.5 to 41 mm; and a focus range from 30 cm to infinity.
This device also features direct point-sampling and high accuracy of orientation. It has a long reading time like the one above. This means that it can retain the readings on screen while it is on and even when it shuts off, the memory will retain the data for you to review again if you need it. But you have to remember not to move the slide controls in order for it to retain the data you previously recorded.
And like the last one, the power automatically shuts off after a minute. Unless if you press the button to shut it off manually. All in all, it is very easy to use.
A critique that brought it down to the second place is that the LED brightness is not adjustable as it said it would be. This is a bummer of course because we expected it to be the case.
