How To Know If Contact Lens Solution Is Too Old To Use

Cleaning and disinfecting contact lenses is critical to their effective use. Failing to care for contact lenses properly can contribute to possible eye infections or discomfort. Ensuring your contact lens solution has not expired and otherwise become ineffective is a core element in keeping your lenses clean and safe. If you are looking for an optometrist near you or have questions about contact lenses, consider the Eyecare Professionals team serving the Mandan, Hazen, or Washburn, ND, areas.

Why Contact Lens Solution Expires

Although the formulations vary by manufacturer, contact lens solutions generally contain chemicals and preservatives that eliminate bacteria and other pathogens on contact lenses soaked in the solution. The chemicals in the solution degrade over time, rendering them ineffective. In some cases, the solution can also become contaminated. It is critical to protect your eyes by avoiding using out-of-date solutions and those made ineffective through improper storage, such as exposing the container to sunlight or heat.

Risks Associated with Using Expired or Ineffective Solutions

All contact lens solutions have expiration or disposal dates on the package label. Using out-of-date solutions risks losing their disinfecting properties, so they may fail to disinfect your contacts properly. Ineffective solutions allow pathogens to remain in your contacts, leading to several possible infections. Expired solutions can result in irritated eyes or allergic reactions, as well as discomfort when using the contacts.

Contact Lens Solution Best Practices

Due to differences in the formulations and packaging of contact lens solutions, a standard shelf life does not exist. However, their maximum life when unopened is two to four years from the manufacturing date. However, once you open the package, the solutions should be disposed of within one day for preservative-free brands or one to three months for those containing preservatives. Check the label on your container to confirm both periods before use.

Do not use an expired or suspected contact lens solution. Instead, wear your backup eyeglasses to ensure your eye safety until you can obtain a new bottle.
