How are extended wear contact lenses worn?

• A. 6 nights 6 days
• B. 24 hours a day
• C. 7 days in a row
• D. 6 nights 7 days of wear

Answer: (D)

Extended wear lenses are meant to stay in the eye for a longer continuous period than daily disposables, often spanning a full week when used as prescribed. The idea is to wear them through days and nights without daily removal, within the safety guidelines given by an eye care professional. The best description among these options is six nights and seven days of wear, which conveys a week-long continuous wear plan. This captures the concept of extended wear over a set period rather than removing them nightly or wearing indefinitely.

The other options don’t fit as well because continuous wear is not guaranteed for every lens or practice, and some descriptions imply either non-stop 24/7 wear without a defined end, or only a week of wear without specifying the nightly element. Always follow the specific lens instructions and clinician’s guidance, and watch for any discomfort or vision changes.
