What is a possible advantage of using silicone hydrogel lenses?

Silicone hydrogel lenses offer enhanced comfort as a significant advantage, primarily due to their properties that allow for better moisture retention and higher oxygen transmission to the cornea compared to traditional hydrogel lenses. This increased oxygen permeability reduces the risk of dryness and irritation, which are common complaints among contact lens wearers. Enhanced comfort is vital for individuals who may wear their lenses for extended periods, as it contributes to a more pleasant wearing experience without compromising ocular health.

The other options reflect characteristics not associated with silicone hydrogel lenses. For instance, silicone hydrogel materials are specifically designed to provide increased oxygen permeability rather than reduced. Additionally, these lenses are generally lighter in mass compared to other types, which contributes to their comfort rather than increasing lens mass. Finally, silicone hydrogel lenses are known to have a lower risk of infection compared to traditional lenses due to their oxygen-rich environment and moisture retention properties, which support better overall eye health.
