What can be said of as the surface area of our field of vision? Isn't it a matter of fairly simplistic projective geometry to calculate this in exact m^2?
>>
the surface area of the night sky

Idk m8
Can you really calculate the surface area when the cone of vision is constantly changing?
>>

Then calculate surface areas of the different cones of vision and put them on a table. It would be interesting to know the max and min.

If a spherical head-encompassing thin paper mask with a radius of 1m was to be used, and someone's FOV was externally outlined on the outer surface of the mask by someone who had continuously checked where the person no longer sees some moving signal in the peripheral vision, would that alone be adept for determining the actual projected shape and area of the FOV on a metric unit sphere?
Is it that simple? On the other hand, how to optimize the center of the paper mask in relation to the person's head? Some kind of center of mass that is in accordance to the eye's position?

the cone reaches to whatever object you're watching
i don't see the point in calculating this

Yes, it was ambiguous to ask the area, what I'm interested in is the projected shape of the FOV on a surface with optimal curvature for this kind of projection. It might not be a spherical surface?
>>
How can the area of human FOV be real if our eyes aren't real?
>>
>>7639641
I think what you really want to find out is the solid angle, measured in steradians, of our vision. Note that men tend to have a wider angle of peripheral vision than women.

It's the opposite.
