There are various types of contact lens cleaners that serve different purposes in the cleaning and maintenance of contact lenses. These cleaners work by cleaning and disinfecting contact lenses to maintain their performance and comfort and to avoid potentially serious eye problems. There are several different types of cleaners, and their uses are typically restricted to a specific type of contact lens. Therefore, it is important that you follow your eye care provider’s directions for the safe cleaning and storage of your contact lenses.
The most commonly used contact lens cleaner is the multi-purpose solution. These products are all-in-one formulas that clean, disinfect, and rinse all at once and can be used for contact lens storage, as well. Not all multi-purpose solutions are meant for use with every type of contact lens. You should check with your eye doctor before using a multi-purpose solution.
Hydrogen peroxide-based contact lens cleaners are also common. These cleaners disinfect the contact lens, removing bacteria and microorganisms that can adversely affect eye health. Most hydrogen peroxide cleaners are either one-step or two-step cleaning systems and have specific methods of storage. After using this type of solution, the lens must be rinsed prior to insertion, or burning and irritation can occur.
Enzymatic contact lens cleaners are a method of removing protein buildup on the surface of contact lenses. They are typically not used on a daily basis, but rather once a week. They are generally small tablets designed to dissolve in storage solution that the contact lens is soaked in overnight. Protein buildup will affect the performance and comfort of contact lenses, and if it is not removed at regular intervals, it can also affect eye health.
Saline solution is another common contact lens solution. Saline solutions are not cleaners; they are used for rinsing other solutions from the surface of the lenses to prepare them for insertion. Contact lens wearers should not rely on saline solution as a method of cleaning their lenses.
Contact lens cleaners are only necessary if you wear daily wear or extended wear contact lenses. Disposable contact lenses are thrown away after a day’s use and therefore do not need to be cleaned. Always use caution when cleaning and handling your contact lenses, and follow the directions for their use and care that your eye doctor provides. Improper cleaning of contact lenses accounts for a large number of eye infections each year and can lead to serious eye injury if left untreated.
