Wouldn't that make sense from an evolutionary perspective? Through human history and prehistory, think of all the common tasks people did on a day-to-day basis. I would say the vast majority of them would involve looking at things below eye level. With the exception of picking fruit from trees or hunting birds in flight, most of the tasks we evolved to do involved looking at things below eye level. Most work with crops involves looking at things below the height of your eyes. Tracking prey involves looking at things below the line of the horizon or tracks on the ground. Crafting objects involves working with your hands and looking down at your work. Raising children involves looking down at their shorter stature.

Why wouldn't our back and neck structure be evolutionarily optimized to look at things a bit below eye level?
