Applications in Optometry

Printable pupillary distance rulers are essential tools in optometry practices, playing a crucial role in the accurate prescription of eyeglasses and contact lenses.

During an eye exam, an optometrist uses a pupillary distance ruler to measure the distance between the pupils of the patient’s eyes. This measurement is crucial for ensuring that the lenses are correctly positioned in front of the pupils, providing optimal vision.

Eyeglasses Prescription

For eyeglasses, the pupillary distance measurement determines the placement of the optical centers of the lenses. This ensures that the lenses are aligned with the pupils, providing a clear and comfortable visual field.

Contact Lenses Prescription

In the case of contact lenses, the pupillary distance measurement is equally important. It helps determine the correct diameter and base curve of the contact lenses, ensuring a proper fit and optimal comfort.

Adding Branding

Adding branding to the ruler is a great way to promote your practice and make the ruler more recognizable. You can upload your logo or create a custom design using the online editor. The logo will be displayed prominently on the ruler, along with your practice information.

Including Additional Information

In addition to branding, you can also add other information to the ruler, such as instructions for use, a chart of common pupillary distance measurements, or a link to your website. This additional information can be helpful for patients and make the ruler more useful.
