  • Be sure to carefully read the labels and instructions of the product you have selected before you prepare your contact lenses for cleaning or rinsing.
  • When using any contact lens solution containing hydrogen peroxide, follow the directions carefully, step by step, to ensure the hydrogen peroxide is fully neutralized before you reinsert the lenses into your eyes.
  • To avoid mix-ups at home, keep lens cleaning solutions containing hydrogen peroxide in a location separate from where you keep solutions for rinsing or moisturizing your lenses.

  • Do not display hydrogen peroxide-based contact lens cleaning solutions beside multipurpose solutions. Organizations that use company-wide shelving plans (such as planograms) should review the placement of these products to reduce the risk of selection errors.
  • In community pharmacies, consider storing hydrogen peroxide-based solutions behind the counter.
  • Share this alert with consumers and patients. Consider posting a copy of the alert near displays of hydrogen peroxide-based lens cleaning solutions.
