Apple files a patent application for a display that can correct a user’s vision
For example, if a user is nearsighted but not wearing glasses, the standard graphical output would be shown on the screen since no correction would be needed for the user to see the screen clearly. If the nearsighted user is wearing glasses, the screen can adjust so that the person using the device won’t have to take off his glasses in order to see clearly.
The device would store the results of the scan so that if the same user was discovered by Face ID trying to unlock the device at a future time, the screen would automatically be corrected. Instead of the scan, the user could input the issues with his eyes.
One pair of glasses could be considered privacy eyewear and when scanned by Face ID, the screen could be viewed only by the user
In other words, the iPhone could recognize whether the user is wearing his corrective lenses. If the user takes his glasses off, the screen could change. As a result, regardless of whether the user is wearing his corrective lenses or not, the image on the display would appear to be clear to him.
Now, how about that privacy eyewear that would keep nosy bystanders from peeking at your phone or tablet’s display? So let’s say that you are using Face ID to read a particular pair of glasses to adjust the screen on your device. When Face ID reads this pair of glasses, the screen adjusts allowing the user to read it clearly while everyone else surrounding the display would not be able to read it.
The name of the patent application is “Systems and Methods for Switching Vision Correction Graphical Outputs on a Display of an Electronic Device” and was originally filed on May 6, 2020. Three inventors are named as the ones that came up with the idea: Lee; Sung Chang; (Saratoga, CA); Ryu; Kee Suk; (Cupertino, CA); Wu; and Wei Guang; (Palo Alto, CA).
