These binoculars come with a Porro Prism design which is designed to alter the orientation of an image. It consists of a block of glass shaped as a right geometric prism with right-angled triangular end faces. It also has fully coated optics which reduces internal light loss and glare, resulting in greater image sharpness and contrast.
The Celestron electric power zoom binoculars has an eye relief of up to 14 mm. This is the distance from the last surface of an eyepiece at which the user's eye can obtain the full viewing angle. If a viewer's eye is outside this distance, a reduced field of view will be obtained
