The main purpose of a rigid lens wetting solution is to?

The primary function of a rigid lens wetting solution is to temporarily convert the hydrophobic surface of the lens to a hydrophilic one. Rigid gas permeable (RGP) lenses are typically made from materials that repel water, which can lead to deposits and discomfort during wear. By using a wetting solution, the surface of the lens is modified so that it can better attract and hold moisture, improving comfort and reducing dryness when the lenses are in place. This property is critical for enhancing the overall wearing experience and ensuring that the lenses remain comfortable throughout the day.

While other options may mention important aspects related to contact lenses, such as clarity and moisture retention, the specific mechanism by which a wetting solution operates is through the modification of the lens surface properties. It’s essential to understand that the temporary alteration of the lens surface to increase its affinity for water directly contributes to the comfort and usability of rigid lenses.
