Blog - What is Pupillary Distance in Glasses
Pupillary Distance (PD) is a calculation of the distance between eye pupils. PD is the distance between the center of your left pupil and that of the right eye. Pupillary distance measurement is required to ensure the center of eyewear is directly before the wearer’s pupil. Besides, PD is needed to ensure your new eyeglasses fit and rectify your vision appropriately.
Lenses should be centered over the eyes to carry out their job perfectively. When eyeglasses are made based on the measurement of the PD, the pupil is correctly aligned with lenses. Lenses usually redirect the light that gets into the eyes so that they can focus straight on the retina.
When the lenses are made to fit your pupil, incoming light is focused. In doing so, eyeglasses help to correct your vision optimally. Well-fitting lenses that are made using the right prescription are vital for seeing and prevention of eyestrain. When it comes to pupillary distance measurement, we use eye recognition software that ensures accuracy is achieved.
A pd ruler is used to calculate the pupillary distance of your eyes. In fact, many eye doctors use a ruler to carry out pupillary distance measurement. Before using your ruler, it is vital to ensure that it will enable you to calculate the pd in millimeters.
That is the standard measurement unit. If your eye doctor did not provide you with any prescription, we’ve got you covered. We employ innovative recognition software to measure your PD accurately. The application scans your eyes to obtain the exact measurement. We do the measurement in less than 30 seconds, and it’s extremely accurate.
Alternatively, you can measure your PD alone or have it measured by a friend.
There are two main ways to calculate the pupillary distance: binocular and monocular PD. Binocular or single PD involves measuring the distance from one pupil to the other. On the other hand, monocular or dual PD constitutes a measure of the distance from the pupil to the nose bridge on each side.
This means a calculation of monocular pd results in two numbers. It is believed that the dual PD is more accurate. This is based on the idea that people's pupil to nose measurement may not be equidistant on both sides. The idea behind monocular pd is to maximize the accuracy of pupillary distance measurement.
We not only help you measure your PD accurately using our eye recognition software but also offer you glasses that perfectly fit your eyes. Whether you are looking for women’s eyeglasses or men’s glasses, we have your favourite eyewear.
