The 10x42 Veo HD2 Binoculars from Vanguard Optics feature extra-low dispersion (ED) glass and BAK4 prisms that work together to virtually eliminate chromatic aberration, which produces images with true color fidelity across the entire wide 65° apparent field of view and enhanced contrast. Complementing the glass and prisms are anti-reflection fully multicoated optics that improve light transmission for bright and clear images with greater low-light performance.
