Which of the following is a drawback of daily disposable lenses?

• A. Increased cost; limited parameter available
• B. Low cost and wide parameter availability
• C. No cleaning required
• D. Long wear duration

Answer: (A)

Daily disposable lenses prioritize convenience, but that comes with two main trade-offs. The most notable drawback is the ongoing cost: you replace a lens every day, so the annual expense tends to be higher than with lenses you wear longer and reuse. At the same time, the range of available parameters—such as base curve, diameter, and powerful options for toric or multifocal needs—tends to be more limited because manufacturers keep daily disposables to a narrower set to simplify production. That can make it harder to find a perfect fit or a needed specialized option. The ideas that there’s no cleaning required or that wear duration is long describe benefits or mismatches for daily disposables, not drawbacks.
