Any stain or mark on the surface of a binocular lens tends to scatter light, thereby producing low-contrast viewing. Compact binoculars are some of the handiest and most widespread of all optical instruments.
The Nikon range of compact binoculars is extensive and will have a pair to suit your needs. Fortunately, the new weatherproof binoculars are fit for rough use. Monoculars are preferred when it is necessary to view stationary objects.
A 7 x 50 binocular shows a view magnified 7 times and it has objective lenses 50 mm wide. Magnification over ten generally causes the binoculars to lose some image crispness. Certain types of binocular lens cloth are even machine-washable using either cold or hot water.
You will not see anything if there is no single star in the sky and no street lights. Waterproof binoculars are preferred for all marine, hunting, birding and other nature related activities.
