Changes in shape and size

If you change the shape and/or size of the prescription lens, you may also have to realign the 0.00 line of the Y-axis.

Take the coordinates from the demo lens as previously described. Change the lens mounting stage with the prescription lenses. Now you have to decide if and how much you want to realign the 0.00 line of the y-axis up or down.

For example, turn the y-axis in such a way that the drill meets the lens 2 mm higher. Move the table so that the drill rests on the rim of the lens and reset both digits (X- and Y-axis) to 0.00. The relation of the coordinates to each other do not change. This means that you can now drill with the same coordinates measured before.

1. original 0.00 line for Y-axis
2. new 0.00 line for Y-axis
