Read on to learn 5 easy methods for measuring pupillary distance yourself.

5 Easy Methods for Measuring Pupillary Distance

Method 1: Use a Ruler and Mirror

This is the simplest way to measure PD—all you need is a ruler and a mirror. Stand in front of the mirror and place the ruler directly on top of it so that you can see both sides of your face in the reflection. Then, measure the distance between each pupil from one side of your nose to the other. This method works best if your pupils look straight ahead without moving around too much or crossing over each other.

Method 2: Ask a Friend for Help

If you’re having difficulty getting an accurate measurement using Method 1, enlisting a friend’s help can make things much easier. Have them stand behind you while looking into a mirror, then measure the distance between your pupils while they hold the ruler in place. This will help ensure that both measurements are taken accurately and consistently, as long as no one moves during measurement.

Method 3: Download an App 

Try downloading a free app like iPDMeasurer or PD Meter on your smartphone or tablet device. These apps use special technology that allows users to accurately measure their own pupillary distances quickly and easily with just their device’s camera lens! All you need to do is take two pictures while gazing into the camera lens – one close-up of each eye – then let the app automatically detect and record the measurements for you!

Method 4: Use Printable Cards/Charts 

You can also find printable cards or charts online that have pre-measured squares designed specifically for measuring pupillary distances at home. All you need to do is print out these cards/charts, find an object like a pen or pencil that fits snugly inside each square, then use those objects as markers while measuring between them with a ruler! It’s easy, simple, and requires minimal effort on your part – no need for an optometrist visit after all!

Method 5: Ask Your Optician

If all else fails, consult with your optician about measuring pupillary distance during an office visit! Most opticians have tools specifically designed for this purpose or can refer you to someone who does — it’s always better (and safer) than trying any DIY methods when it comes down to something as important as eye health!
