The optics field is quite large and the number of products is considerable. The quality of a pair of binoculars rests on their crystal clear visibility.
There are different generations of night-vision binoculars. Still, recent trends have brought down the price to more affordable levels. Compact binoculars are generally guarded with rubber padding, and they come with a case and hanging strip.
You will need a magnification factor of at least 7, maybe up to 10 if you have a steady hand. They can withstand complete immersion in water and remain dry on the inside. How well your binoculars will serve you in low light conditions is described as twilight performance.
Choosing a telescope is not an easy choice to make and is one that really needs research. The anti-reflective lens coating on compact binoculars reduces glare to a great extent. You may not be planning on getting them wet, but things happen; you might trip and drop them in a mud puddle, take them out on a foggy day, or you might get caught in a freak rain shower.
You want to look for lightweight, tough, comfortable ones with clarity. But if you're into astronomy, you'll need a high powered pair.
