The 2 Pupil Eye

Advantages


Stereo View: If you have 2 eyes, this would be Quad View.

Terrorize people: If you saw someone with eyes like this you would crap yourself .

Disadvantages


Total Brain Confusion: Since the human brain has not evolved to process this type of vision you would probably pass out from confusion. Upon regaining conciousness you would pass out again creating an unending loop of conciousness and unconciousness that would only end with your death.
