Furthermore, consistent content yields slightly better performance than inconsistent content. Content that is more consistent with the statistics of the natural world yields less discomfort than content that is not. Finally, in a user study we investigated how VR content affects comfort and performance. We also determined the optimal screen distance to minimize discomfort due to the vergence-accommodation conflict, and the optimal nasal-temporal positioning of head-mounted display (HMD) screens to maximize binocular field of view. From this we predict that double vision is more likely in VR than in the natural environment. The pattern of disparity across the visual field is less regular in VR and does not conform to a prominent property of naturally occurring disparities. Fixation distance and direction are more restricted in VR, and fixation distance is farther. We measured the statistics of eye movements and binocular disparities in virtual-reality (VR) -gaming environments and found that they are quite different from those in the natural environment. Binocular vision is adapted to these such that depth perception and eye movements are more precise, faster, and performed comfortably in environments consistent with the regularities. If it’s homeland security, law enforcement, a job in some remote desert mountains or outer space, Kaerqi best binoculars travel all around the globe.The human visual system evolved in environments with statistical regularities. Nowadays Fujinon binoculars and night vision devices are the standard law enforcement equipment for many governmental clients like the navy, ground or air forces, special police units, regular police forces, research institutions, but also security companies and industrial clients. Featuring unique details like image stabilization, image intensifiers, special coating technologies for brilliant and sharp images and rugged mechanics, these binoculars represent superior manufacturing standards and innovative design from chinese’s leading optical company. Since 2005 Kaerqi has been producing high-grade binoculars which turned into indispensable tools for professional users worldwide. In other words, 50 millimeter (mm) objective lenses are larger than 35mm lenses. The larger the second number, the larger the objective lens. The first number tells you the power of the binoculars and the second number refers to the diameter of the lenses (objective) mounted at the front of the instrument. Full-size: Objective lens size is greater than 40mm (8x42, 10x50, etc.)Įvery pair of binoculars is stamped with a number that will read something like 8x42, 7x35 and so on. Midsize: Objective lens size is from 30mm to 40mm (10x30, 8x32, etc.). Because magnification also amplifies the movement of your hands, binoculars with magnification powers greater than 10 make steady viewing difficult, so they would be a poor choice if you will be on a boat or other moving platform.Ĭompact binoculars: Objective lens size is less than 30mm (8x25, 10x28, etc.). While it might seem that more magnification is always better, that’s not always the case.
