When you need to get prescription glasses, a lot goes in to making the proper glasses for you. There is more to getting the right set of prescription glasses than going to the eye doctor and getting your prescription. There are many different filters you can add to your glasses, but one of the more essential elements of getting a prescription lens is your pupillary distance. Eyewear Candy Optical RX will share more about pupillary distance and why it is important to get the right pupillary distance when ordering your glasses.
Why Is Pupillary Distance Important?
Pupillary distance is the measurement between the center of the pupils. The pupillary distance will determine where the person looks through the lens of the glasses. The measurement of the pupillary needs to be accurate for a number of reasons. If the pupillary distance is off, it can cause blurred vision, double vision, fatigue, headaches, and nausea. Even a small error of the measurement for pupillary distance can result in frequent headaches. Many people who experience symptoms may have never realized that their pupillary distance is wrong. There is more to just getting prescription lenses than having a prescription. You will also need your pupillary distance properly measured.
What is Normal Pupillary Distance?
The average pupillary distance for an adult ranges between 54 to 75 mm. For children, the average distance between pupils are 43 to 58 mm. The pupillary distance is used just for the lenses in your prescription glasses. It aligns the optical center of the lens which will result in more comfort and clarity. The pupillary distance matters less for those with low myopia prescriptions. Being a millimeter or two off will not have a major effect. However, for those with high myopia prescriptions and or have an astigmatism, they will need their measurements perfect. One of the many reasons why it is critical to have a perfect measurement is due to how light will hit the retina. When the pupillary distance isn’t correct, the light will hit the retina which will in turn cause blurriness.
Single VS Dual Pupillary Distance
When measuring for you pupillary distance, it is important to know if you have a single or dual pupillary distance. Both are important when measuring for eyeglasses. A single pupillary distance is the distance between the center of the pupils and the center of the bridge of the nose. Dual pupillary distance is the distance of the center of each eye’s pupil to the center of the bridge of the nose. You will have two different measurements for each eye. When you are getting progressive lenses it is important to know if you have single or dual pupillary distance to ensure your eyeglasses are comfortable.
