What type of contact lens is categorized as a daily disposable lens?

Daily disposable lenses are designed for single-day use, providing convenience and hygiene for the wearer. Soft hydrogel contact lenses fall into this category as they are often manufactured specifically for daily disposability. These lenses are made from soft, flexible materials that allow for a high level of oxygen permeability, which is essential for maintaining eye health throughout the day. At the end of the day, the user simply discards them, reducing the risk of buildup of proteins and contaminants that can occur with lenses worn for longer durations.

In contrast, rigid gas permeable lenses, hybrid lenses, and prolonged wear lenses do not typically fit the definition of daily disposables. Rigid gas permeable lenses are usually designed for longer-term wear, as they require cleaning and occasional replacement but are not disposable on a daily basis. Hybrid lenses combine a rigid center with a soft skirt and also do not fall under the disposable category. Prolonged wear lenses are intended for extended use, often for several days or even weeks, before they require cleaning or replacement. Thus, the characteristic features of soft hydrogel contact lenses align perfectly with the definition of daily disposable contact lenses.
