Perspective you mean?

If these three objects are stationary, the owl has the largest viewing angle, it can turn its head 360 degrees, the cat is flexible, but not so much. Astronaft limited visor helmet, he sees only what fits into the glass review.

Yes, since we want one word could perspective replace viewing angle... Haha and I just scrolled up again and sees he said search term. My bad.

Your option may be the winner. Viewing angle, this is my guess, but, I'm not sure that this is so))
