Been using the Pupil Distance PD Glasses & VR app for a couple months now. It’s basically an app that lets you measure your pupillary distance, which is the distance between your pupils. This measurement is super important when getting new glasses or using VR headsets.
Here’s what you do: you just take a picture holding a credit card or reward card up to your face, and the app uses that for scale to calculate your PD. There’s also some info on what PD is and why it matters. Took me a bit to figure out at first but it’s pretty straightforward once you get the hang of it.
Look, if you wear glasses or use VR, you’ll probably find this app useful. It’s not perfect – the instructions could be a bit clearer – but overall it does the job. Worth checking out if you need to measure your PD.
