An eye measure app works by leveraging facial recognition software on compatible devices like iPhones and iPads to automatically scan and measure your pupillary distance (PD).
Understanding the Process
These apps are designed to make obtaining your PD reading simple and convenient from home. According to information about this type of app, the core mechanism relies on the device's built-in facial recognition technology.
Here's a breakdown of the typical process:
- Download the App: You first need to download the eye measure app onto your supported device (iPhone or iPad). These apps are usually found on the official app store.
- Position Your Device: Once the app is open, you simply hold your phone directly in front of your face, about a foot away.
- Automatic Scan: The app then automatically begins to scan your PD using the facial recognition capabilities of your device. It identifies key facial features, particularly your pupils, to calculate the distance between them.
- Receive Measurement: The app processes the scan and provides you with your PD reading.
Key Features and Accuracy
Apps utilizing this method claim to offer a good degree of accuracy for obtaining your PD measurement.
- Technology: Uses built-in facial recognition software.
- Supported Devices: Works for iPhone and iPad devices.
- Claimed Accuracy: Claims to be accurate up to 0.5mm for providing the ideal prescription PD reading.
