Why do Asians have small eyes compared to the rest of the world? What's the evolutionary reason behind no shift in their phenotype?
There was more than one human prototype but all can interbreed.
God made them that way.

TVs emit a lot of harmful radiation, smaller eyes let them watch anime all day without getting eye cancer. This is especially helpful with shows that are extremely carcinogenic, such as haremshit or shonenshit.

They don't have smaller eyes, they just have an epicanthic fold. And there isn't any known reason why. It's probably just random variation.

Size is the same except they have a fold of additional fat tissue in the corner of the eye to help in extreme cold conditions.
Whites (the blond, northern types) also have this vestigial feature because the common ancestor to both Whites and Asians evolved in Central Asia and Siberia.
Pic related. You can see the layer that makes his eyes taper down at the edges.
This is common in northern European races like Germans, Scandinavians, some Slavs and Russians.

Their diet consists largely of rice. After many generations of Asians being constipated their entire lives and squinting while straining to relieve themselves, the random mutation of permanent squinting was selected for.

Right, that's why the Inuits of northern North American, the whatever people that live on Greenland, the indigenous Russian/Finnish/Icelantic peoples etc have "slanty" eyes as well. Inuits look asian as fuck
