How to Clean Gas Permeable Contact Lenses
Gas permeable contact lenses, also known as GP or RGP lenses, are a popular choice for many contact lens wearers due to their durability and ability to provide sharp vision. However, like any other type of contact lens, proper cleaning and maintenance are essential to ensure the lenses remain comfortable and safe to wear. In this article, we will discuss the step-by-step process of cleaning gas permeable contact lenses and answer some frequently asked questions about their care.
Step-by-Step Guide to Cleaning Gas Permeable Contact Lenses:
1. Wash your hands: Before handling your contact lenses, it is crucial to wash your hands thoroughly with a mild soap and dry them with a lint-free towel. This step helps prevent the transfer of dirt, oils, and bacteria onto the lenses.
2. Remove the lenses: Gently remove one lens from your eye by sliding it down onto the white of your eye and pinching it with your thumb and index finger. Repeat the same process for the other lens.
3. Rinse the lenses: Place the lens on your palm and apply a few drops of multipurpose contact lens solution or saline solution. Gently rub the lens in a circular motion with your fingertip for about 20 seconds. Make sure to rinse both sides of the lens to remove any debris or protein buildup.
4. Clean the lens case: Rinse your lens case with fresh multipurpose solution and let it air dry. Avoid using tap water or saliva to clean your case, as they may introduce harmful bacteria.
5. Soak the lenses: Fill your lens case with fresh multipurpose contact lens solution or the recommended disinfecting solution. Place each lens in the corresponding side of the case and close the lid. Let the lenses soak for the recommended time, usually 4-6 hours or overnight.
6. Rinse the lenses again: After the soaking period, remove the lenses from the case, and rinse them with the multipurpose solution to remove any disinfectant residue.
7. Store the lenses: Place the lenses in the clean and dry case, ensuring they are fully submerged in the solution. Close the lid tightly to prevent contamination.
8. Repeat the process daily: It is essential to clean and disinfect your gas permeable contact lenses every day to maintain their clarity and comfort. Avoid wearing lenses while swimming or in environments with excessive smoke, as these can cause irritation and damage to the lenses.
