Adjusting the interpupillary distance of the eyepiece

Adjusting the interpupillary distance and diopter

Before starting observation, it is necessary to make adjustments on interpupillary distance and diopter. If users continue observations without making the adjustments, they may suffer eye fatigue. Also, if the adjustments are made, differences of visual acuity between the right and left eyes are corrected, facilitating viewing with both eyes. This also minimizes deviation in focus when the magnification is changed.
