Which is an advantage of GP lenses compared to soft contact lenses?

Choosing the option that highlights decreased lens deposits as an advantage of gas permeable (GP) lenses compared to soft contact lenses is insightful. GP lenses are made from rigid materials that allow oxygen to pass through, which typically results in a smoother surface compared to the porous structure of soft lenses. This smooth surface is less likely to attract and retain deposits from tears, such as proteins, lipids, and other debris, reducing the frequency of lens cleaning and the likelihood of discomfort or vision issues related to build-up over time.

In contrast, soft contact lenses tend to have a higher affinity for these deposits due to their hydrophilic nature and larger surface area, which makes their upkeep more challenging. This translates to GP lenses often being more durable and requiring less frequent replacement due to the reduced accumulation of deposits, which can enhance the overall health and comfort of the wearer’s eyes.

The other options, such as increased comfort and better aesthetics, may be true in specific scenarios but generally do not encompass the primary advantages associated with GP lenses. Increased comfort is often a characteristic of soft lenses, while aesthetics can be subjective and vary between individuals. Additionally, while GP lenses do provide a wider range of prescriptions, this point does not directly address the benefits of deposit resistance that
