A clean contact lens is the core behind keeping your eye healthy. If you wash your hands very consciously and then rub & rinse the lenses gently, even after that, there is scope for the pathogens to grow in a dirty contact lens case. Even after using contact lenses safely, millions of people carry a risk of eye infection due to following reasons:
- Poor hygiene
- Using extended-wear lenses
- Quantity of exchanged tear getting reduced under the lens
- Environmental factors
Risk of infection varies somewhat depending on the type of contact lens. Single-use daily disposable lenses are the safest type of soft contact lens, in terms of reducing the risk of infection. Rigid gas permeable lenses are a safer alternative than any type of soft contact lens. Your ophthalmologist can help you decide which type of lens is right for you. Regardless of the type, you decide on, proper care of the lenses is essential to eye health.
Therefore, for the sake of your precious eyes, we would like to suggest you to follow the instructions mentioned below which have been developed in partnership by the American Academy of Ophthalmology, the Contact Lens Association for Ophthalmologists, the Cornea Society and the American Society of Cataract and Refractive Surgery:
- Wash your hands with liquid soap and water before applying or removing your contact lenses, including when you open or close the lens storage case. Then rinse and dry them with a lint-free towel.
- During cleaning, rub your contact lenses with your fingers, then rinse the lenses with solution before soaking them. This “rub and rinse” method is considered by some experts to be a superior method of cleaning, even if the solution you are using is a “no-rub” variety.
- Rinse the contact lens case with fresh solution — not water. Then leave the empty case open to air dry.Discard used solution immediately after removing your lenses from the case each day.
- The contact lens should be kept clean and we would like to suggest you to replace it regularly, at least every three months. Lens cases can be a source of contamination and infection.
- Do not use cracked or damaged lens cases.
- Old or ‘top-off’ the solution should not be re-used in your lens case.
- Contact lens solution should not be transferred into smaller travel-size containers. This can affect the sterility of the solution, which can lead to an eye infection.
- Do not allow the tip of the solution bottle to come in contact with any surface, and keep the bottle tightly closed when not in use.
- Always consult the instructions for the lenses or the contact lens solution to determine if re-disinfecting the lenses is appropriate before you wear lenses which were stored in the case for an extended period of time. If the lenses were stored for more than 30 days, then just DO NOT wear them without re-disinfecting.
- If you use contact lenses sporadically then you should consider using single-use daily disposable lenses.
- Try to make contact with water as less as possible even if you are going into a hot tub or removing lenses.
- The contact lenses should neither rinse with nor store in water (tap or sterile water).
- Saliva is not a recommended solution to wet the lenses.
