about 135 degrees
Our eyes are the natural start of perception of FOV. In human vision, the field of view is composed of two monocular FOVs which our brains stitch together to form one binocular FOV. Individually, our eyes have a horizontal FOV of about 135 degrees and a vertical FOV of just over 180 degrees.
