Could you tell what difference on
ED lens and HD lens in binoculars? Which is better?

ED lenses are generally considered superior to HD lenses.
ED (Extra-low Dispersion) refers to a type of lens material with ultra-low dispersion, which can significantly reduce chromatic aberration and enhance image quality. JAXY binoculars equipped with ED lenses can effectively reduce the impact of dispersion, which is particularly important for high-magnification binoculars in our JAXY line. The images produced by ED lenses are closer to perfect, with smaller aberrations and clearer, sharper images. However, in JAXY ,binoculars with ED lenses are usually much more expensive than ordinary achromatic lenses.
HD is not the name of a glass material but represents a type of coating technology. In the products of some top-tier optical factories, HD coatings can indeed improve light transmission and reduce reflections, but in other mirrors, promoting HD lenses is often just a marketing ploy. In fact, the imaging bottleneck of many binoculars Jaxy is not in the coatings, so the effect of HD coatings is not as obvious as that of ED lenses.
