Never wipe dust or dirt off your valuable binoculars using your handkerchief or shirt sleeve. There are many options from very sophisticated binoculars for surveillance or night navigation to simple binoculars for kids to have fun with.
This Leupold 10x50mm tactical binoculars is waterproof and fogproof. The best models will be ones with a very large objective lens, suitable for use in many conditions, but will be too heavy and cumbersome for use on the move. Each telescope has an objective lens, an eyepiece, and an exit pupil.
Glass also has a tendency to reflect as much as five percent of the light that arrives at its surface back towards the light source. Folding in the eyepiece between observations will protect the eyepiece against scratches or other inadvertent damage. Earliest documented history shows Hans Lippershey as the first telescope maker including both monocular and binocular variety even though he is not the first person to actually design and produce such a device.
You will find these to be quality binoculars that won't break should you drop them. Galactic clouds and star clusters look dim when viewed by the naked eye, but with binoculars they are much clearer. They can be extended or retracted as needed.
Binoculars now come with all sorts of gadgets and gizmos that never used to be available. Binoculars are the perfect accessories for hiking, fishing and hunting.
