Measure it with one of these free tools, then type the number in below. Each one opens in a new tab, so nothing you've chosen here is lost.

• EyeMeasure ↗ Free iPhone app. Uses the Face ID depth camera, so it's the most accurate option here — hold the phone up and it reads instantly, nothing to hold or tap. Needs an iPhone X or newer.
• PDMeasure.com ↗ Works in any browser, on a phone or a laptop — nothing to install. Runs on your own device; no photo is uploaded.

We can't see these tools or read their results — enter the number they give you below.

Copy the PD from your prescription — it's usually written as a single number near the bottom, or as two numbers separated by a slash. If it isn't listed there, switch to I need to measure it.
