Lens solution refers to the liquids used to clean, rinse, disinfect, and store contact lenses. Using the correct solution type is essential for safety and comfort.
Types and Functions
Solutions may include multipurpose liquids that both clean and disinfect, separate cleaning and soaking agents, hydrogen peroxide systems, and saline for rinsing or filling specialised lenses. Each has specific instructions and compatibilities.
- Multipurpose solutions are common for soft reusable lenses
- Hydrogen peroxide systems require neutralisation before lenses touch the eye
- Saline alone does not disinfect and must not replace disinfecting steps
- Rigid and scleral lenses often need dedicated cleaning and conditioning fluids
Safe Use
Always follow the manufacturer’s and practitioner’s guidance, and do not mix brands without advice. Using expired or inappropriate solutions can lead to discomfort or infection.
- Discard solution from the case after each use; never “top up”
- Keep bottle tips clean and avoid touching them to any surface
- Store solutions at room temperature and close caps firmly
- Inform your practitioner about any stinging or reactions when using a new product
