When will we see the first consumer headsets with retina-resolution displays? Here’s what Meta’s CTO says.
Andrew Bosworth was asked this very question in his recent AMA on Instagram. Bosworth answered:
Meta’s “time machines” and the pursuit of retina-resolution headsets
Strictly speaking, a retinal VR display would be one where you could not tell the difference between a display and natural vision. In the VR industry, a PPD of 60 is generally considered the threshold for retinal resolution. However, human vision is capable of much more, as Bosworth points out.
Current devices are far from 100 PPD, let alone over it. According to Meta, the Quest 3 has a PPD of 25, the Vision Pro is estimated to be around 34 PPD, and the Varjo XR-4 achieves 51 PPD in the center of the screen.
By “time machines,” Bosworth is referring to Meta’s headset research prototypes, which are designed to provide a glimpse into the future and show how certain technologies could one day have an impact.
In 2022, Meta introduced the Butterscotch prototype, which has a PPD of 55. To achieve this, the team developed a new hybrid lens and reduced the field of view by half. This was followed in 2023 by the Butterscotch Varifocal, which added a varifocal display and offered a PPD of 60.
Both prototypes are not intended to become products, but are for research and demonstration purposes only.
