Field of view
The field of view corresponds to the total area that can be seen with binoculars
The focusing distance is the shortest distance at which it is possible to focus
The relative brightness is used to find the optical quality binoculars by poor lighting. So more the relative brightness, the higher the brighter when ambient light is low.
The exit pupil is small circle of light that you see taking your binoculars at arms length. Its diameter is obtained by dividing the diameter of the front lens by the magnification
The eye relief is the distance required between the eye and the lens to get the best picture possible. Those who wear glasses need a relatively long eye relief (at least 13 mm)
Diopter correction devices allow you to adjust the image to the view of users whose eyes are not the same force
