Gerber Coburn has upgraded the software used in its Dimetrix lens verification and finish blocker, which automatically verifies and blocks single-vision, multi-focal and progressive lenses. The new features are the frame mode, which allows the operator to view both eyes prior to blocking the second lens, and new left and right prism imbalance settings to ensure that progressive lenses are within prism tolerances. The machine can also automatically recognize dotted lenses, a feature that helps to reduce manual blocking time.
