You don't actually need 'high-definition' vision to recognize objects, as proven by a tiny mammal that sees the world in a blur.

Transformation-tolerant object recognition in tree shrews despite lacking a fovea

The Takeaway
Humans have a 'fovea'—a spot in our eyes that gives us razor-sharp focus—and we’ve always assumed this is essential for high-level visual intelligence. But tree shrews lack this hardware entirely, yet they can still recognize complex objects even when they are moved or rotated. This discovery proves that 'object constancy' (knowing a cup is a cup from any angle) happens in the brain’s software, not the eye’s hardware. You don't need a 4K camera to have a smart AI, and animals don't need 'HD' vision to navigate a complex world. It suggests that intelligence is about how you process the blur, not how clear the picture is.
From the abstract
Object recognition depends on the ability to extract stable representations across changes in how they are viewed, yet it remains unclear how this capacity depends on visual acuity and cortical hierarchy. We combined behavioral testing and computational modeling to determine whether tree shrews, close relatives of primates with lower spatial acuity, can perform transformation-tolerant object recognition. Front-end modeling incorporating species-specific optics and photoreceptor sampling showed t
