Prescription lenses with different thicknesses

With very thick lenses and/or unusual shapes it may be necessary to support the lenses on the mounting stage by means of the PVC strips. Use the strips to get the front surfaces of the lenses in a horizontal position to make drilling easier and more precise.

With the supporting disks you can also support the lenses from the center. This is recommended for small lenses which only rest on small rims and might be deformed by putting pressure on them when fastening onto the mounting stage. The graduated scale under the PVC pad makes it easy to find the same position for left and right supporting disk.
