There are a lot of issues when it comes to choosing binoculars for bird watching. Outdoor conditions can contribute to situations which can damage binoculars.
You buy the telescope and go home, put it up and go to look at the Moon. Each telescope has an objective lens, an eyepiece, and an exit pupil. Law enforcement agencies prefer to use second-generation binoculars.
So the Bashability factor is also important to look at when purchasing binoculars. Prices of modern day monoculars range from the most expensive to very cheap. Properly cared for, a good pair of binoculars will serve you for decades.
Usually only magnification below 5X works well for night binoculars. A good warranty is your ticket to trouble free repair.
