Contacts, like a point-and-shoot photographer, move with the center of the eye to keep the ideal light-bending power where it will have the greatest impact, while more static eyeglasses cover the majority of the field of vision with the same magnification to provide clarity at every angle. Higher resolution means not just more pixels — that is, more bits of light data — but smaller pixels, because resolution is a measurement of data spread across a given area.
With a consistent number of pixels, a greater field of vision, aka a larger screen, would actually translate to worse resolution as the data are diluted across a greater area.
Since the upper limit of what the human eye can perceive is controlled by pixel distance , not pixel number, there is no reason to assume that 8K screens go beyond what viewers can appreciate. But the benefits of 8K have a lot more to do than just expanding screen sizes.
So the theoretical limit on how much detail the human eye can actually process may be more of a guideline than rule. Martinez-Conde points out that the enigma encompasses all types of perception. Sources are provided for informational and reference purposes only.

From pixel to picture: How our eyes turn light into imagery Light — whether concentrated in pixels or unfiltered as a flood of tiny photons from the 3D, physical world — arrives at the eye in a diffuse, illegible mess. The fovea centralis, located in the center of the retina. Saccades, or involuntary twitches help form a mental model of what you see in front of you.

If you look down at the sand closest to you, you can easily count the individual grains, right? But the farther you look, the more difficult or impossible it becomes. For example, for a inch 8K TV, you would need to sit two feet or less away from it in order to appreciate its full impact.
