What is a listed benefit of bi-weekly disposable lenses?

• A. Economical
• B. Most expensive
• C. Best for extended wear
• D. High deposition risk

Answer: (A)

Bi-weekly disposable lenses are designed to be changed every two weeks, which tends to make them more economical than daily disposables. Because you replace lenses less often, the cost per day is generally lower even though you still get a fresh lens every two weeks. The other statements describe downsides or mismatches: they aren’t the most expensive option, and extended wear suitability depends on the lens material and approval for overnight use rather than the replacement schedule. High deposition risk isn’t a benefit either; it’s something you manage with proper cleaning and replacement timing. In short, the replacement cadence often lowers cost per day, which is why economy is listed as the benefit.
