The details
Photoshop Elements has offered a similar fix for nearly a decade, but it borrows eyes from another photo, with mixed results. Lightroom instead generates new eyes that match the photo’s lighting and pose, using other images of the person in your library so colour, size and shape stay true. Photoshop can do this too, but not with one tap or for free.
Why it matters
Generative fixes are moving from professional tools into one-tap features in everyday apps. That makes edits easier, but also makes it harder to tell whether a photo shows what actually happened, which is why provenance labels and disclosure matter more.
