Skyview Optical Co. Limited

BRIGHT AND WIDE VISUAL FIELD The refection-free filter gives a brighter and wider field of vision, resulting in less fatigue even after long-time use. EASY TO OPERATE It has a separate control for streak width and streak rotation. Streak width never changes while rotating. The entire head is rotatable so that you can easily shoose the best position to use. It is compact and light. ENDLESS ROTATION The streak revolves 360 degrees without stops(except RX-1), enabling quick measurement of astigmatic axis. The built-in head rest prevents the operator's spectacles from getting acratched. The presbyopic +2D lens is easily fitted into the aperature in the head. (Standard equipment: +2D presbyopic lens, Optional: +3D and +1D presbyopic lenses.)
