Contact Lens Protein Removal Techniques
Protein deposits are a natural occurrence for the contact lens wearer. The deposits come from interaction between the protein naturally found in the tears and the contact lens. Proteins deposits area visible, and appear as a thin haze covering the lens. There are two types of protein deposits; native and denatured.
Native proteins are transparent and naturally exist in our tears. They are not too harmful to the contact lens wearer and can be removed from the lens easily. Denatured proteins are an opaque deposit that clings to lens. It causes increase discomfort and cloudy vision. These deposits encompass 90% of the protein deposits contact lens wearers’ face.
Routine cleaning will not remove protein, so a special protein removal solution should be used once a week or as recommended by a physician. It is important to note that protein cleansers do not remove dirt and oils, or disinfect and should not be used for such purposes.
Protein removal is most often recommended for soft contact lenses, but can be used for hard contacts as well. Lenses worn for longer periods of time will naturally accumulate greater protein deposits and therefore require more effort toward protein removal. Protein removal requires it’s own unit. Your doctor will recommend a particular solution. Most often a multi-purpose protein removal solution is recommended.
