What action should be taken if excessive dryness is observed in a soft contact lens wearer?

When excessive dryness is observed in a soft contact lens wearer, checking for proper insertion techniques is critical. This is because improper insertion can lead to the lens not being seated correctly on the eye, which can cause discomfort and dryness. If the lens is not adequately positioned, it might not be able to maintain its moisture effectively, leading to increased dryness for the wearer.

Inserting lenses incorrectly could also lead to issues such as air bubbles trapped under the lens or an inaccurate fit, both contributing to discomfort. Ensuring that the lens is inserted and positioned correctly can help in restoring moisture retention and providing a more comfortable wearing experience.

Other options, such as changing the lens material or increasing the diameter, could be considerations later, but they do not address the immediate action that should be taken to alleviate the symptoms of dryness. Reducing lens thickness may also change the comfort level but isn’t the first step to take in addressing potential insertion errors. Therefore, verifying and correcting the insertion technique is the optimal action.
