Our retina only needs ~8 megapixels - the same number of pixels as 4K/UHD (3840x2160 is 8,294,400 pixels).
High pixel density is only required at the middle of where our gaze is - the surrounding can be highly compressed because our eyes are not very sensitive. No pixels are required where our blind spot is, and our colour and light level sensitivities varies from fovea outwards, so there are other compression possibilities too.
If the display can "move" with your eyes (high pixel density only for fovea e.g. contact lens) then the display also only needs a limited number of pixels.
