They consist of a framework of reduced dimensions, closed at one of its sides by a removable cover, which once deployed will also serve as a sunscreen for the binoculars. Said cover, when deployed, will leave uncovered the optical system of lenses of the binoculars, which is comprised of two groups; the first or fixed group will be that closest to the eyes of the user, with a system of negative aspherical eyepieces corrected for better vision, said system being secured to a rotary support which will only allow said optical system to be deployed or retracted. The second optical group arranged in the same line of viewing as the first is an optical system of spherical-aspherical objective corrected for better width of field, and is able to move in a linear manner to move toward or away from the first lens and thereby achieve the proper focus of the object being observed. <IMAGE>
