[QUOTE="Binastro, post: 3622887, member: 111403"] I agree Lars. In addition, although the vertical FOV of the eyes is limited, the view is still there, but blocked by our foreheads and eyebrows. I realised this when wearing wrapround dark glasses and coming indoors saw a huge black area that was blocked. It is our brains that deal with the areas blocked including the areas blocked by our nose. We should see these areas as black but don't. With the 6x18 binocular the FOV is only 7.5 degrees, approx 45 degree AFOV. I did not like the view with vastly extended horizontal view even though centrally I got stereo vision. I much prefer 75 to 80 degree AFOV older Porroprism binoculars and normal views. [/QUOTE]
