Piggy-backing is the term used to describe wearing two lenses at once in the same eye.

If a rigid corneal lens is very uncomfortable to wear, a soft hydrogel lens (with no prescription) can be used underneath to act as a cushion - which is also sometimes referred to as a bandage lens. This is an attempt to minimise corneal rubbing with the rigid lens and to enable it to be worn comfortably. Many people manage to successfully increase their wearing time with this management or can use it as a temporary measure when needed.

Both lenses need to be cleaned thoroughly and handled differently. Regular contact lens appointments need to be kept to check the fitting and ensure that enough oxygen penetrates through both lenses.
