Side-by-side comparison

DimensionDaily disposable lensesMonthly / planned-replacement lenses
What the schedule meansA new pair is used each day and the old pair is thrown away. FDA defines "disposable" as used once and discarded.The same pair is removed and re-worn for several days before replacement. CDC says replacement schedules for these soft lenses can vary from seven to 30 days.
Is it an FDA category?FDA defines a true daily wear disposable schedule as a brand-new pair of lenses each day.The FDA and CDC pages read do not use the word "monthly". The closest terms are frequent or planned replacement, with CDC giving a seven to 30 day range.
What "disposable" on a label tells youA true daily disposable is used once and discarded.CDC notes some soft lenses are labeled "disposable" but may be removed nightly and re-worn for multiple days, so the label alone does not show the schedule.
What happens at the end of the dayDiscard the lenses at the end of each day and put in a new pair the next day (CDC).Remove the lenses and clean and disinfect them properly before they go back in (FDA). Store them in fresh contact lens solution, never water (CDC).
Lens caseNot addressed for daily disposables on the CDC healthy-habits page read.CDC: replace the case at least once every three months, and avoid mixing fresh and old solution in the case.
Use beyond the intended scheduleCDC: wearing daily disposable lenses for more than one day may cause eye discomfort or other complications.CDC: replace lenses as often as your eye care provider tells you.
Wear schedule is a separate questionDaily wear versus extended wear is a different axis from replacement schedule. FDA describes extended wear as overnight or continuous wear ranging from one to six nights or up to 30 days.The same applies: how long a pair is kept and whether it is slept in are separate questions. CDC: avoid sleeping in lenses unless directed by your eye care provider.
Rest between extended wear periodsFDA: the eyes should have a rest without lenses for at least one night following each scheduled removal of extended wear lenses.The same FDA statement applies to any lens worn on an extended wear schedule.
Who sets the scheduleCDC: most soft lens wearers must replace lenses according to a schedule prescribed by an eye care provider.The same CDC statement applies. Talk to your eye care provider about the proper schedule for your specific type of lens.
When to pick eachNeither is a general recommendation. The schedule your eye care provider prescribes for your lens type decides.Neither is a general recommendation. The schedule your eye care provider prescribes for your lens type decides.
