Can contact lens solution cause an allergic reaction?
Contact lens solutions: An overview
Contact lens solutions are used to clean and disinfect contact lenses. These solutions come in various types, including multipurpose, hydrogen peroxide-based, and saline solutions. Multipurpose solutions are commonly used as an all-in-one solution for cleaning, rinsing, and storing contact lenses. On the other hand, hydrogen peroxide-based solutions require extra steps to disinfect lenses, such as using a special case and neutralizing tablets. Saline solutions are used for rinsing contact lenses but do not have any disinfecting properties.
Contact lens solution allergies: Symptoms and causes
Some people may experience an allergic reaction to contact lens solution. Symptoms of an allergic reaction may include redness, itching, burning, and tearing of the eyes. In severe cases, an allergic reaction may lead to corneal ulcers or even vision loss. The cause of an allergic reaction to contact lens solution may vary from person to person. Some people may have an allergic reaction to specific ingredients in the solution, such as preservatives or disinfectants. Others may have a reaction to the proteins found in natural tears that have accumulated on the contact lens surface.
Preventing contact lens solution allergies
If you experience symptoms of an allergic reaction to contact lens solution, it is important to stop using the solution and contact your eye doctor. Your doctor may recommend switching to a different type of solution or to daily disposable contact lenses. To prevent allergic reactions, it is essential to follow proper contact lens care guidelines, such as washing your hands before handling lenses, replacing contacts as recommended, and storing lenses in a clean and dry case. Additionally, it is essential to avoid sharing contact lens solutions with others and not to use expired solutions.
Contact lens solution recalls
While rare, there have been instances of contact lens solution recalls due to contamination or other safety concerns. For example, in 2006, Bausch & Lomb recalled their ReNu with MoistureLoc contact lens solution due to an outbreak of a rare eye infection known as Fusarium keratitis. This infection was linked to the use of the ReNu solution and led to several cases of vision loss or blindness. It is essential to stay informed about any product recalls or safety concerns related to contact lens solutions and to follow proper care guidelines provided by your eye doctor.
The bottom line
Contact lens solution allergies are rare but can cause significant discomfort and even vision loss. Symptoms of an allergic reaction include redness, itching, burning, and tearing of the eyes. To prevent allergic reactions, it is crucial to follow proper contact lens care guidelines, use solutions as recommended, and avoid sharing or using expired solutions. In case of symptoms, you should contact your eye doctor immediately. Staying informed about product recalls and safety concerns can help ensure that you are using safe and effective contact lens solutions.
