Beastmen's emotions weren't as profound. For males, their feelings toward females and cubs were more about instinct and responsibility. And since females could have many Beast Husbands and cubs, they also tended to view life and death with a certain detachment.
However, Li Gu was an emotional female. Her son and several Beast Husbands had been killed one after another, and this intense grief had her constantly in tears. Coupled with the poor sanitary conditions of the Beastmen, frequent eye-rubbing could lead to corneal infections, damage, and eventual blindness. That much was plausible.
But for Yin Jiang's Grandma to go blind right after was a bit strange.
Grandma was old and could no longer bear children. Her Beast Husbands were from many years ago; by now, some were dead and others were crippled. Any decent food from their hunts, she gave to her son, the Clan Leader.
