ED glass has this unique characteristic and when combined with other glasses minimizes the effects of the secondary spectrum. Comparing to achromatic lenses, and ED glass reduces chromatic aberration to a remarkable degree. So if you would like to observe in low light conditions, such as at dawn or dusk and it is better to use an ED glass Binocular. 24mm eyepiece，easy to find the object，ensures more light passing to ease up your eyestrain. And at the same distance, the big 24mm Eyepiece makes sure more of the object can be seen. This SV202 binocular is of low density (about 1.8g/cm3 magnesium alloy, high impact load capacity and high quality magnesium alloy body. So you don't have to worry about breaking it outdoors. 100% waterproof internals to handle the most extreme weather conditions, ensuring you can watch uninterrupted views. 50mm objective lens gathers more light and that you will see objections brighter and larger. So this 10×50 binocular is good to be used in lower light environments and in special in stargazing/astronomy, where a 50mm objective lens diameter is not that bad in observing some deep-sky objects. BAK4 has a high refractive index and lower critical angle than other materials, which means it transmits light better with less light being lost due to internal reflectionsuch as from internal bubbles trapped during the manufacturing process. Fully Multi-coated Glass means multiple coatings on all lens surfaces. And all air-to-glass surfaces are anti-reflective multi-layer coated. Fully multi-coated lenses are typical of high-end optics. The diopter adjustment is a control knob on your binocular. It is designed to let you compensate for differences between your own two eyes. Once you set the diopter, then the two barrels should stay in proper relation. From then on you can focus just by turning the central focusing knob. Whether you wear glasses or not, you can find the comfortable observation position by adjusting the eyecups.
