How long can two-week disposable lenses generally be worn?

Two-week disposable lenses are designed to be worn for an extended period, typically ranging from one to two weeks, based on daily wear. The correct answer reflects the intended use of these lenses, which is to be worn continuously for up to two weeks before needing to be discarded. This timeframe is critical because wearing them longer than recommended can lead to an increased risk of developing eye infections or experiencing discomfort due to protein buildup or reduced oxygen flow to the cornea.

In contrast, other options suggest wearing the lenses for a duration that exceeds or does not reach the manufacturer’s guidelines. One week would be too short considering some individuals might be able to comfortably wear them for that entire two-week period. A month exceeds the safe wear duration, as extended use beyond two weeks can compromise ocular health. Three weeks also surpasses the recommended timeline, risking potential complications. Therefore, maintaining adherence to the two-week usage guideline ensures optimal eye health and comfort.
