Eyes see the world kinda like cameras – we have sensors that are somewhat like pixels, and just like cameras they have a minimal resolution that they need to be useful, and on the contrary having an insanely high resolution doesn’t really create that much of a difference after certain point. That resolution is dependent on how many sensors can be fit in your eyeball, so small animals have higher eyeballs compared to their body so that they could fit in that minimum, meanwhile larger animals rarely go much beyond that minimum so they don’t need bigger eyes
