The optics on the Vision Pro are... well, they're not fantastic. It's a challenge to blow up displays that small to meet your field of view. Peripheral vision on the Quest 3 is far better, but the displays are over double the size, which made the lens design problem less challenging.

Apple have since purchased at least one lens design company [0], so future iterations of the Vision Pro should hopefully be less optically-challenged.
