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.
The first number is the magnification. The second number is the diameter in millimetres of the lenses.
The higher the magnification, the smaller the field of view. The greater the diameter of the main lenses, the more light it collects, so the fainter objects they can see.
For advice, go to a good telescope shop. 10 or 12 X 50 are a good size, but it depends on what you want to do. You may also benefit in the medium term by having a tripod or some type of support for them.
