Side Effects of 3 Contact Lens Solution Ingredients

Just because something’s carefully developed and manufactured doesn’t mean it’s perfect for everyone. That’s exactly the case of contact lens solution ingredients. Scientists have been perfecting solution formulas for years, but some ingredients are simply dangerous for certain people especially if the liquid’s not used properly.

Out of all the usual ingredients found in contact lens solutions, we’ve come across three of them with side effects you need to be aware of. Here’s all you need to know about hydrogen peroxide, boric acid, and sodium chloride.

Hydrogen Peroxide

This is probably the most common ingredient for contact lens solutions. You can find it on the label of almost every solution product you see in stores.

Benefits

The reason for hydrogen peroxide’s popularity as a solution ingredient is how effective it is for cleaning and disinfecting contacts. It can loosen the hold of debris, lipids, and protein deposits around the lens to easily remove them.

And, the best part? Hydrogen peroxide doesn’t contain preservatives. Preservatives are a big no-no for contact lenses and your eyes for they can trigger allergies caused by hypersensitivity.

Usage

Hydrogen peroxide should never be applied directly on your eyes or even your contacts. A neutralizer suitable for the process must be used together with the chemical. Without it, nothing can convert the chemical into oxygen and water.

There are two ways in adding a neutralizer. The first one is by simply doing it while you’re disinfecting. This is easier if your contact lenses’ storage cases already contain a neutralizer.

You may also disinfect your contact lenses first before neutralizing them. Some solution products come with a tablet that can neutralize your disinfected lenses.

Never forget to read the instructions. Most products will require you to neutralize your contact lenses for a minimum of six hours.

If you have no choice but to buy a separate bottle of hydrogen peroxide solution for your contacts, make sure to consult a specialist. Different products have different concentrations that may or may not harm your eyes.

Side Effects

Improper use of hydrogen peroxide will lead to the following consequences:

  • stinging or burning sensation in your eyes
  • damage in your cornea
  • irritation

Boric Acid

When it comes to eliminating bacteria and fungi from your contact lenses, boric acid is a superior ingredient. More importantly, in the right amount, it remains as a mild chemical.

Benefits

The main purpose of boric acid based on its ophthalmic advantage is to be the primary ingredient of eyewashes. It can keep your eyes free from smog and other pollutants to prevent irritation.

Usage

Boric acid is already contained in the solution. You don’t have to add it anymore unlike the method of using hydrogen peroxide. However, avoid it if it’s combined with polyvinyl alcohol. Those two ingredients tend to cause adverse reactions together.

Unfortunately, some people are allergic to boric acid. The chemical is also dangerous when it penetrates open wounds, scratches, injuries, and infections not just in your eyes but on your body as a whole. In fact, it’s hazardous as well for your ears, nose, and mouth even if they’re perfectly fine.

And, surprisingly, using boric acid is also a big deal if you’re pregnant or nursing a baby. Consult your doctor first before buying a contact lens solution with the said chemical.

Side Effects

Based on the side effects of boric acid as an eyewash, keep an eye out for these symptoms caused by a possible allergic reaction to the chemical:

  • breathing problem
  • swelling
  • hives
  • stinging or burning feeling in your eyes
  • throbbing pain in your eyes
  • temporary vision problem
  • irritation
  • red eyes
  • excessive tears

Also, some solution formulas with boric acid can discolour your contact lenses. That’s more likely to happen on soft contacts.

Sodium Chloride

Just like boric acid, sodium chloride is also commonly used as some sort of treatment or cleaning solution that’s directly applied to the eyes. However, it can also be an ingredient in contact lens solutions.

Benefits

Sodium chloride can treat swollen eyes. It’s a popular eye medicine when it serves as the main ingredient of a solution.

Usage

There’s no need for extra procedures when using a contact lens solution with sodium chloride. Just follow the instructions carefully.

As for people who should think twice before using a product containing sodium chloride, they must visit a specialist first if they have existing vision problems, eye infections, allergies, and concerns about fertility, pregnancy, or breastfeeding.

Side Effects

These are the adverse reactions you may get from using sodium chloride solutions:

  • painful eyes
  • temporary vision changes
  • red eyes
  • irritation
  • swelling
  • itchiness
  • rashes

Additional Tips on Using Contact Lens Solutions

Remember these general maintenance tips to keep your contact lenses clean and your eyes safe:

  • Always clean your hands thoroughly before disinfecting and storing your contact lenses.
  • Place one lens covered in solution on the palm of your hand and gently rub it with the forefinger of your other hand to completely remove buildup (sometimes, it’s not enough to just soak the lens).
  • Empty the case every after cleaning to prevent reusing the solution.
  • Clean the case with hot water or a sterile solution and air-dry it before pouring a fresh contacts solution in it.
  • Use a hydrogen peroxide cleaning solution if other primary ingredients harm your eyes.
  • Close the case every time you’re putting one lens on your eye to avoid contaminating the other lens.
  • You may put some solution on the finger holding the lens to make insertion easier for you.
  • The solution should fill half of the case to ensure the lenses are completely soaked.
  • Avoid non-saline solutions for your eyes’ safety.

If you don’t want to go through any maintenance whatsoever, you should choose daily disposable contact lenses. You can immediately throw them out after use.
