Which type of lens fitting involves the application of both soft and rigid contact lenses together?

The correct choice describes a hybrid lens fitting, which specifically refers to the technique of combining both soft and rigid gas permeable (RGP) lenses. This method utilizes the benefits of both lens types: the comfort and improved fit of the soft lens, alongside the visual clarity and correction of astigmatism that the RGP lens provides.

In hybrid lens fitting, the RGP center is surrounded by a soft lens skirt, allowing for enhanced comfort while still maintaining excellent optical performance. This fitting is particularly beneficial for patients who require correction for conditions like keratoconus or those who prefer the comfort of soft lenses but still want the advantages of RGPs for better vision.

Additionally, while other options may relate to contact lens fitting in various contexts, they do not specifically encompass the combination of soft and rigid lenses that defines hybrid fitting. For example, bandage lens fitting focuses on protective lenses used primarily for healing purposes, while piggyback fitting involves layering lenses (typically a soft lens over a RGP for comfort), rather than a hybrid approach. Thick lens fitting is not a recognized fitting method in this context, highlighting the specificity and correctness of the hybrid fitting terminology.
