Think deeply for a moment about what is happening. Light is coming in at certain angular limits - lets call this the 'angle of view' and in the case of our eyes its something like 90 degree cones for each eye - and the eye is focussing it onto a small sensor called the retina.

What binoculars, telescopes and magnifying glasses do is modify the Angle of view from which light is being collected, then REFOCUS it onto the eye and retina! Actually, so do photographic lenses.

Let me explain that a bit more. A telescope, for example, will grab light from a cone much smaller than our normal angle of view/field of view of 90 degrees per eye, then refocus and shift the light rays to project them onto our WHOLE retina! So it is as if our retina didn't change in size, but our eye focussed light from a much smaller cone - say a 5 degree cone rather than 90 degree cone - onto it.

The result is that the full visual acuity of our retina is focussed on a much smaller part of the world, and that part of the world appears to increase in size - it is 'magnified'.

In other words, they modify the ANGLE OF VIEW, also know as the FIELD OF VIEW, in order to magnify! IT is the very PRINCIPLE by which magnification works!

ANGLE/FIELD OF VIEW is FUNDAMENTAL to magnification!

well, if you want to use real binoculars to zoom into the narrow FoV (as selected) of the (any) computer game as displayed on your monitor and view the pixels real big... go right ahead.
With regard to the (any computer) game and selecting a narrow Fov, and using in sim (assuming the game has them available) binoculars, you'll find that changing the FoV and zooming in or out are not the same thing.

Our brain then figures out distance to interpolate actual size. OF course, our brain does not know exactly how much of our field of vision something occupies - it receives information from the retina. So it is actually the size of an image on the retina that is used to judge apparent size. This allows us to trick the brain by bypassing the normal cone of vision our eye projects onto the retina, and thus make a small angle of view occupy more of our retina! Thus, we have magnification.

Lenses
A convex lens bends the light that goes through it toward a focal point. The light spreads out again past this focal point. Magnifying glasses are convex lenses. When you use one, the lens bends the light rays so that they come together and focus on the lens within your eye. The light then spreads out as the rays continue past the focal point, and they hit the retina of the eye. The spreading of the light makes the image viewed appear much larger than it really is because it causes the image to take up more space on the retina. Moving the magnifying glass closer or farther away from the eye will change how much the light is spread on the retina. The closer the magnifying glass is to the eye, the bigger the image will appear.

No... lenses are... but that seems omitted from your addin to your previous post...

FoV (or as you'll interchange them now Angle of View) is the amount (the angle) the lens "sees"... magnification, via a series of lenses as with binoculars, brings that image closer (or further away if you look down the wrong end)
