It's not lo. I can't believe how many people still believe this. It's not intentional. It's an unintentional side effect of the high FOV. Even single displays experience this effect. It's just not as noticeable. We have no modern method to rid us of this FOV scaling distortion. It works much the same way that real life optics work, stretching things further away from the center
