FAQs About Contact Lenses

Do I need to use protein-removing tablets?
Yes and No. The dirt that gets onto the lenses partly comes from the environment (for example dust) and partly from the eye itself. The tears contain many compounds which stick to the lens and need to be removed to keep them clear, comfortable and safe. The four main components from the tears that get onto the lens are fats, protein, mucus and calcium. Using a daily rub-and-rinse procedure on removing the lenses will remove almost all of these four compounds. However, protein is the most difficult to remove and so after a period of several days or weeks a thin film of protein may form on the lenses. Protein-removing tablets are designed to remove this film - note that they will not remove any other type of deposit. Some peoples' eyes produce more protein than others and so may have to use the protein tablets more or less often, also some lens materials tend to attract protein more than others. You still need to clean your lenses daily even if you use protein-removing tablets to get rid of the other types of deposit that accumulate.
