Contact Lens Cases is the least glamorous corner of a lens routine and the easiest one to neglect, which is exactly why it is worth its own page. The case is where a lens spends most of its life, and the condition of the case has a great deal to do with the condition of the lens.
This category currently holds the PROGENT Menicon large diameter lens case, sized for scleral lenses. A scleral lens is considerably wider than a soft or rigid corneal lens, and a standard case will not hold one without the lens pressing against the walls, so a purpose sized well matters more here than it does elsewhere.
Cases are consumables, not equipment. Rinse the wells with solution rather than tap water, then leave them open to air dry face down on a clean tissue. Replace the case at the interval your eye care professional recommends. If one is cracked, cloudy or has a cap that no longer seats properly, replace it rather than squeezing a few more weeks out of it.
