Yes, binoculars use similar lenses to telescopes but with a system of prisms to fold the light path to permit binoculars to be much shorter than a regular telescope.
Monocular eyepiece had only one lens while binocular only has 2.
The lens you look through in a telescope, binocular, or microscope is called the eyepiece. It is the lens closest to your eye that magnifies the image produced by the objective lens.
A binocular microscope has an eyepiece lens and an objective lens for each eye. This design provides a three-dimensional view of the specimen being observed, as each eye sees a slightly different angle. Binocular microscopes are commonly used in research labs, medical facilities, and educational settings for their improved depth perception and comfort during extended use.
Use binoculars/telescope & a card to look at the Sun. Point the binoculars at the Sun, then put the card behind the one lens of the binocular while the other is covered.
Binoculars are specified by numbers such as 4×30, the first number gives the magnification of the object and the second number gives the aperture in millimeters. Good binoculars with a large aperture (50 mm or more) are useful at night for astronomy.Read more: binocular
Binoculars uses lenses for magnification mainly. Two convex lens and prisms are used
The total magnification achieved when using a 100x oil immersion lens with a 10x binocular eyepiece is 1000x (100x objective magnification x 10x eyepiece magnification).
Usually 7x or 10x, but if the binocular lens is bigger than 80mm in diameter, maybe 12x or 15x.
To read binocular numbers accurately, look for two numbers separated by an "x" on the binoculars. The first number represents the magnification power, while the second number indicates the diameter of the objective lens in millimeters. For example, if the binoculars have numbers "8x42," it means they have 8x magnification and a 42mm objective lens.

You would use a convex lens.
Well...You could drop it. Or set it on fire. Or steamroller it. Use your imagination.
