What is the purpose of a wetting solution in contact lenses?

The purpose of a wetting solution in contact lenses is to create a hydrophilic lens surface. This hydrophilic property enhances the lens's ability to retain moisture, making it more comfortable for the wearer. A surface that is hydrophilic will attract water, which helps prevent dryness and maintains optimal hydration for the lens, contributing to overall comfort and visual clarity during wear.

Additionally, a well-hydrated lens surface can help reduce deposits that may otherwise accumulate on the lens, further enhancing comfort and maintaining clear vision. While the other options may relate to lenses in some capacity, they do not accurately describe the primary function of a wetting solution, which is to enhance surface wettability and comfort for the wearer.
