Adjusting for maximum sharpness. Many people have slightly different vision
between their eyes. When using binoculars, this difference can be easily
compensated for by turning the dioptre adjustment wheel. On DBA compact
models this wheel is located on the bottom of the main body.
To set the binoculars correctly, close your right eye and look through the left
eyepiece with your left eye and using the centre focus wheel - focus on an object
of your choice until it is clear and sharp. Next, close your left eye and look
through the right eyepiece with your right eye. You may find the object being
viewed is not absolutely sharp and this can be corrected by rotating the dioptre
adjustment wheel (but without turning the centre focus wheel) until the object
being viewed becomes sharp. The binoculars are now set and a perfectly clear
and sharp image should be attainable when using both eyes together. To focus at
different distances simply turn the centre focus wheel.
Rubber Eyecups are designed to position your eyes correctly to get the maximum
comfortable field of view with or without glasses and are often unique to each
individual binocular.
Using glasses. Opticron DBA binoculars provide the full field of view when
wearing glasses. To maximise field of view with glasses on, turn eyecup assembly
clockwise into the ‘down’ position - remembering to return them to the upright
position if you or anybody else wants to use them without glasses.
