What is the effective method for removing protein from a gas permeable lens?

Using enzymes is the most effective method for removing protein from a gas permeable lens because enzymes are specifically designed to break down protein molecules. Gas permeable lenses can accumulate protein deposits from tears, which can lead to discomfort and decreased lens performance. Enzymatic cleaners contain proteolytic enzymes that effectively digest these protein residues, making it easier to remove them from the lens surfaces.

Other methods, while helpful in lens care, may not target protein build-up as effectively. Routine cleaning might maintain overall cleanliness, but it does not specifically address protein deposits. Soaking in saline can help rinse away some debris but does not contain the active ingredients necessary for breaking down protein. Disinfecting with alcohol might clean the lens, but it is not formulated to remove protein deposits and could potentially damage the lens material over time. Thus, the enzymatic approach is the optimal choice for effective protein removal in gas permeable lenses.
