Continuous wear lenses are worn for up to how long?

• A. Up to 30 days and nights
• B. Up to 7 days
• C. Up to 14 days
• D. Up to 90 days

Answer: (A)

Continuous wear means you don’t remove the lens for an extended period, including overnight. For many extended-wear soft lenses, the maximum recommended continuous wear is up to 30 days and nights, thanks to higher oxygen permeability that helps keep the cornea healthier during overnight and multi-day wear. The exact duration depends on the specific lens material, the manufacturer’s approval, and the clinician’s guidance. Some lenses are approved for shorter continuous wear or for daily wear only, and 90 days is not a typical recommendation. So, up to 30 days and nights best reflects what these lenses are designed to allow when used under proper supervision.
