One Eye or Two, it's up to You

Hamlet never said: "Monocular? or binocular?, that is the question." But I bet he never knew the difference between the two. Do you know the difference?

Monocular scopes tend to be smaller and lighter, plus you don't have to mess with separate eye focusing. Binoculars can be more comfortable for longer periods of use but can make readjusting to the ambient light a little difficult. With a monocular scope you can keep one eye open to retain your natural night vision, which is a definite advantage at night.
