If the Vision Pro has a horizontal field of view of 100 degrees and the resolution of the display has 3660 horizontal pixels that corresponds to 36.6 pixels per degree.  Therefore the image will have a resolution of 18.3 line pairs per degree (one pixel for black and one for white).  The human eye has a visual acuity of 60 line/pairs per degree.  Therefore it will be possible for someone with well corrected eyesight to see the individual pixels.  Ideally a 100 degree field of view should have 12,000 horizontal pixels.  It will be a few years until we have displays with this resolution.  In the meantime Apple will need to balance field of view and resolution to provide an immersive experience with a high quality image.
