The Health app on your iPhone can be used to add and update your vision prescriptions. This way, you can check your vision details and compare changes when you switch to new glasses or lenses. This can help people who wear glasses or contact lenses by giving them a digital record of their eye tests when buying new glasses or checking for improvements during an eye exam.

You can upload a scanned copy or PDF of your prescription to add it to Health; or manually enter your vision data measurements to save it. The Health app lets you save more than one prescription for your vision, and all of your data is stored securely on your iPhone and accessible at all times.

In this post, we'll explain how to add your vision prescription in the Health app on your iPhone.

If you wear glasses or contact lenses and have recently visited your optometrist for an eye exam, you can add your updated vision data in the Health app.
