Editorial policy
We use clear words and link to the sources behind our guides. A link does not mean the source endorses eyePD.
The single vs dual PD guide, near vs distance PD guide, and PD label reference were clinically reviewed on October 6, 2026.
The guides explain general information. If you have questions about your report, ask the eye care office that gave it to you. For questions about an order form, ask the retailer.
