What characteristic does a profiled gas permeable lens have that differentiates it from standard lenses?

A profiled gas permeable lens is distinguished by its thinner overall profile compared to standard gas permeable lenses. This design is often adopted to enhance comfort and fit, allowing the lens to sit more naturally on the eye. The thinner profile reduces the weight of the lens, which can improve wearability, especially for those who use lenses for extended periods. Additionally, the design aims to optimize oxygen transmission to the cornea while maintaining visual acuity and fitting characteristics. Hence, the unique attribute of a profiled lens that sets it apart from traditional designs is its reduced overall thickness, making it a more advanced and user-friendly option in the realm of gas permeable contact lenses.
