Which wear category is defined as being worn for up to 30 days and nights?

• A. Daily wear
• B. Flexible wear
• C. Extended wear
• D. Continuous wear

Answer: (D)

Continuous wear means you may keep wearing the lenses continuously, including overnight, for up to 30 days and nights, as long as the lenses are approved for that wear schedule and the eye tolerates them. This differs from daily wear, where lenses are worn only during the day and removed before sleep. It also differs from older interpretations of extended wear, which generally referred to overnight use but not for as long as a full 30 days. In practice, only certain lenses (often silicone hydrogel types) are approved for continuous wear, and following the clinician’s guidance and maintaining good hygiene are crucial because the longer you wear lenses without removal, the greater the risk of complications such as infection or hypoxia.
