Nice video! Can you explain the 3rd # that some binoculars have, the degree? Eg 8 x 24 7.5 degrees?

I'm still wondering what does it mean by this "5m/500000m" text written on my binoculars...

[@TeaParty1776]

My Nikon is 9X25 5.6. What is the 3rd number?

[@shasashu]

And no info about the eye lens!!
What impact does smaller vs larger diameter eye side lenses make?

[@barbarawashington7612]

You didn't listen. The wider the diameter of the lens, the more light it lets in. Therefore you see more color and detail, and it's better in cloudy or low light conditions, such as viewing in the understory of the forest.

So am guessing if you have 80x80 binoculars that's good ?? Can anyone tell if that's good!??!?

[@shajadaakther2779]

Mine is 70×70. I can't see things at near distance!

[@psychologdg9443]

Nice magnification though..

Feasibility vs visibility

[@ahmadbinfadzil8258]

Better have two types of Binoculars, 80x 80 and 22x 25.
