From the Manufacturer: LandScout binoculars are great, all-purpose binoculars at an affordable price that can bring a new level of enjoyment to almost any activity: sporting events, sightseeing, birding and wildlife observation, hiking, and more! Coatings and Prisms Inside the LandScout are two pairs of Porro prisms, reflective optical prisms that take the form of a right-angle triangle with two sides of equal length. Porro prisms make binoculars more compact without compromising focal length or the transit of the light rays as they pass through it giving it the classic “broad-shoulder” shape of a traditional binocular. Our Porro prisms are constructed of K9 optical glass, which provide high reflectivity so that more light passes through the optical path to your eye. LandScout also contains other optical surfaces treated with special coatings to boost light transmission even more. The result is a brighter view than uncoated binoculars.
