Which category do soft lenses primarily fall into?

Soft contact lenses are primarily categorized into types based on their wear schedule, and among those categories, extended wear and daily disposable lenses are prominent. Soft lenses can be designed for daily wear, meaning they are worn during the day and removed at night, while others may be intended for extended wear, allowing users to wear them continuously for several days or even weeks without removal, depending on the specific lens design and materials used.

The daily disposable lenses are a popular choice as they offer convenience and a low risk of complications associated with cleaning and storing lenses, promoting better eye health. The extended wear soft lenses, made from materials that allow for more oxygen permeability, are designed for longer wear, making them suitable for patients who prefer not to remove their lenses nightly.

By contrast, options like single-use and daily wear refer specifically to certain types of wear schedules without encompassing the various specific designs of soft lenses. Rigid gas permeable lenses, while an important category in themselves, are distinct from soft lenses due to their different material properties and fitting characteristics. Additionally, bifocal and trifocal refers specifically to lenses with multiple prescriptions for different viewing distances and does not classify the lens type itself.

Thus, the focus on extended wear and daily disposable accurately captures the broad category of soft
