Hunter's comment
This pupillary distance measurement tool lets you take that measurement yourself—no optometrist appointment needed—and it’s as easy as taking a selfie. The tool works with your smartphone (and its own app) to take the measurement needed to ensure things like eyeglass frames and a VR headset fit properly.
