Regardless of the type of lens (RGP or soft), proper care and storage of contact lenses worn for a longer period of time is essential to ensure good eye health and wearing comfort.
Contact lenses that are cleaned improperly or not at all increase the risk of microorganisms such as bacteria, viruses and fungi, as well as foreign particles such as eye makeup or dust building up in the eye or on the lens. As a result, the cornea may become damaged, requiring the wearer to pause from wearing the contact lenses.
The main hygiene steps include:
- Cleaning (incl. protein removal) and disinfecting (incl. neutralising). All-in-one solutions and peroxide care systems are both used for cleaning contact lenses. All-in-one solutions are suitable for manually cleaning, storing (including overnight) and disinfecting soft contact lenses. Peroxide solutions can be used for soft and RGP contact lenses alike and are particularly recommended for allergy sufferers. They are free from preservatives and highly heat-resistant, which makes them ideal for holidays in the sun. It is important to ensure that the neutralising step has been fully completed to avoid eye irritations.
- Rinsing off cleaning and disinfecting solutions. Sterile saline solutions are recommended for this step.
- Wetting. Re-wetting solutions that contain no preservatives are available for all contact lenses, providing immediate and long-lasting relief for strained eyes. Wetting drops ensure good moistening of the eye for long-lasting, improved visual performance.
