Discovery Kids – 4 x 35 Binoculars : When you pick up a pair of binoculars, it’s like looking through two telescopes at the same time! They are easier on the eyes than a telescope as there is less eye strain when viewing objects and scenes. Focusing is achieved by moving the central wheel on the bridge between the two eyepiece tubes. These 4 X magnification binoculars are lightweight and compact, making them convenient to carry around. Features comfortable eyecups and 35 mm objective lenses.
