Your Pupillary Distance (PD) is the distance between the centres of your pupils, and it is used to position your lenses correctly. Accurate PD measurement helps to ensure that you are looking through the optimal part of each lens, which supports clear, comfortable and natural vision. It is a small but important detail in making your spectacles just right for you.
Why PD matters
When your lenses are aligned to your pupillary distance, your eyes can focus naturally and comfortably. This is especially important for stronger prescriptions and for multifocal or progressive lenses.
- Helps centre your lenses accurately
- Supports comfortable, natural focusing
- Particularly important for progressive lenses
How we can help
We measure your PD precisely as part of fitting your spectacles, so that your lenses are made and positioned just for you. This attention to detail helps your new glasses feel comfortable and perform at their very best from the first time you wear them.
If you are due for new spectacles or an updated prescription, we warmly invite you to book a comprehensive eye examination with our practice.
