The diopterallows you to adjust the viewfinder sharpness to match your own eyesight. Adjustment of the Diopter Setting The focal lengths of the two eyepieces must be adjusted to conform to differences, if any, between your two eyes so that the images in both eyepieces are in focus simultaneously. Many cameras feature a built-in adjustable diopter correction system, this means it's not necessary to attach an eyesight correction lens to the camera to adjust the diopter setting. BACKGROUND OF THE INVENTION [0003] Eyepieces are usually equipped with a diopter adjustment system so that even observers with a vision defect can see clearly without fatigue over a long period of time. The diopter adjustment is a control knob on your binocular.
