Description DMV Vented Scleral Cups are used mostly for inserting Synergeyes (hybrid) contact lenses, although some scleral wearers use them for insertion. They are not suitable for removal of lenses. The DMV Vented Scleral Cup has a completely hollow shaft, while the standard DMV Scleral Cup is closed at one end, allowing you to control and release suction. Includes hard plastic case.
