The Meopta 8x42 MeoPro Air HDED+ Binoculars provide a superior viewing and handling experience by combining well-engineered optics with an exceptional eye relief and comfortable exit pupil in a lightweight and ergonomic housing. Extra-low dispersion (ED) fluoride glass lenses, treated with proprietary anti-reflection MeoBright multicoatings, and compact Schmidt-Pechan prisms deliver vivid true-color images that are bright and crisp across the entire field of view. The lenses are further treated with Meopta's proprietary MeoShield and MeoDrop exterior coatings that protect the lens surfaces from scratches and makes cleaning oils and other contaminants easy without leaving residue. These coatings ensure the lenses stay free from imperfections that can interfere with your glassing experience and let you immerse yourself in the view. The optical system, combined with the magnification and lens diameters, produce a long eye relief and wide exit pupil that compliment the wide viewing angle—this translates to a viewing experience that virtually eliminates eye strain and greatly reduces the need to move your head from side-to-side to see the whole scene in front of you. Meopta designed the binoculars with ergonomics in mind to minimize user fatigue during long observations. Its large center focusing wheel is easy to use with either hand and a dioptric correction dial, located on the focusing knob, ensures precise focusing even if you normally wear corrective eyeglasses. Giving truth to the Air's name, the housing is made from a lightweight and durable magnesium alloy that is center weighted by the prism design, so they sit comfortably in the hand, and they have an open-bridge/dual-hinge design that further cuts weight without sacrificing strength or stability. Protective rubber armor wraps the body and provides a slip-resistant grip, especially in cold and wet conditions. The housing is nitrogen filled and sealed to be waterproof and resistant to internal fogging in extreme conditions. Meopta MeoPro Air 8x42 HDED+ Binoculars 1032368
