Flexible Wear (FW) lenses can be worn as:

Flexible Wear (FW) lenses are designed to offer versatility in how they can be used, allowing for both Daily Wear and Extended Wear. This characteristic means that wearers can choose to use these lenses in a way that fits their lifestyle and comfort needs.

Daily Wear refers to using the lenses during waking hours and removing them before sleep, which is typical for most contact lenses. Extended Wear allows the lenses to be worn continuously for a specified period, usually overnight for up to several days, depending on the manufacturer's recommendations.

FW lenses are made from materials that provide adequate oxygen permeability, thus making them suitable for extended use without compromising eye health. This flexibility is what allows them to be categorized under both usage patterns, which benefits wearers who may prefer different wear times on different days or who may experience specific situations where continuous wear is advantageous.

The other options would limit the usage of FW lenses to either just daily wear or just extended wear, which does not accurately reflect their multifunctional design.
