What is the recommended method for cleaning rigid gas-permeable lenses?

The recommended method for cleaning rigid gas-permeable (RGP) lenses is to use a proper RGP lens solution and avoid tap water. This choice is supported by the need to ensure that the lenses are cleaned effectively while minimizing the risk of contamination and irritation to the eyes. RGP lens solutions are specifically formulated to clean and disinfect the lenses, removing debris, protein deposits, and other contaminants that can accumulate on the surface of the lenses during wear.

Using tap water can introduce microorganisms and other contaminants that may lead to infections or complications. Additionally, tap water may not have the same pH balance or osmotic pressure as appropriate lens solutions, which can potentially harm the lenses or the eyes. Therefore, adopting specialized lens cleaning solutions that are designed for RGP lenses is essential for maintaining eye health and lens integrity.

Alternative methods like soaking in vinegar solutions are not standard or recommended practices, as they may irritate the eyes or damage the lenses. Thus, selecting a proper RGP lens solution ensures effective cleaning and safety for the wearer.
