“I would not say it is common, and 17 is certainly extreme. Typically people think that their contact has fallen out so they put another one in on top of the previous lens. Usually these folks have relatively small corrections so their vision is not terribly affected until the ’stack’ gets fairly tall,” Hinshaw told Gizmodo. “We commonly will use two contacts in pathological states such as keratoconus. In that case it is usually a gas permeable on top of a soft lens.

The lump is surgically opened and there is the contact lens. Often the lenses are still usable!”
