10x—that’s what the first part of 10×50 means. The 50 is the size of the front lenses in millimeters.
These binoculars magnify your view ten times. The 50 merely indicates the diameter of the objective lens (The big one) in millimetres.
10x normal vision
The diameter of the lens controls how much light it receives. If the ratio is 7×50 that is considered night vision because they pick up more light than the normal eye. 10×50 is comparable to 7×35 in light gathering. but magnifies. 10x is about the limit for normal people without a tripod.
The 10x part means whatever you look at will appear 10 times closer to you. The 50 means that each lens is 50mm wide.
Zoom means the ability to smoothly change magnification. 10×50 binoculars have a fixed magnification of 10, no Zoom. The 50 is the diameter of the objective lenses in millimeters.
