In this article, we will review with you what PD measurement is, why it is so important, and how it is measured, seeking to provide accurate information to renew the concept of its importance and our commitment to providing standards and precise details for the safety of your children.
- So what is PD?
PD is an abbreviation for pupillary distance, which is a number that expresses the distance between the centers of the right and left eyes
- Why is your pupillary distance measured?
Naturally, every eyeglass lens has a center. This center is the clearest of vision than the rest of the lens parts. For more comfort in vision, the lenses must be installed in a specific way so that the clearest center of the lens is in front of the center of the eye, and thus the distance between the two pupils of the eye (the PD ) becomes exactly the same. The distance between the centers of the glasses lenses after installation, and if this distance is not matched correctly, the glasses wearer may suffer from some visual problems such as blurry vision or headaches.
- How do you know your child's PD size?
It is always better to have it measured by a doctor or optometrist and technician
If you do not find it written in the prescription, you can take your child to any optical center and you will be helped with this matter within seconds and with ease.
- How to measure PD?
Although we always recommend that it be measured by a trained specialist to be more accurate, let us tell you how and the best way to try it on your child at home.
All you need is a regular measuring ruler
Then sit in front of your child, approximately 50 cm away and at the same height, so that your face is facing his face, and ask him not to move his head.
Then ask your child to close one eye well with his palm, then start placing the ruler on his forehead so that the number zero starts from the center of the open eye.
Now ask him to move the palm of his hand from the first eye to the second eye to close it and open the first without moving the ruler.
Then follow the numbers of the ruler to know what number will be in front of the second eye.
This number will be the distance between your child’s eyes, which is called the PD. You must repeat the matter more than once to ensure consistency and ensure accuracy.
**We always recommend seeking the help of trained professionals in this matter to ensure accuracy**
To become more reassured, our selected lenses in our store have been manufactured with freeform technology to provide greater width in the center of the lens and greater clarity than similar regular lenses 😉
