Contact lenses and eye health
There are two types of contact lenses available: rigid gas-permeable and soft.
Contact Lenses may be used on a daily wear basis, and either discarded each day (daily disposables) or disinfected and re-used, or an extended wear basis where they are kept in overnight. Dr. Randhawa will let you know the most suitable lens type, wearing schedule, replacement frequency and care regime for your need Never switch the type of lens or solution you use except on Doctor's advice.
Remember that contact lenses can only be fitted by or under professional supervision. Regular aftercare check-ups, at intervals determined your doctor, are essential to keep your eyes healthy and to keep you in the best lenses for your needs, which may change over time. Improper lens wear and lens care habits develop slowly over time and can damage the eye - regular check ups ensure that you are on the right track.
Just as your eyes keep changing, contact lenses are constantly improving so even you were unable to wear contacts in the past, it is worth trying again. Today almost everyone who needs vision correction and wants to wear contact lenses can do so.
Risks of wearing contact lenses
There is a slightly increased risk of eye infection associated with contact lenses. Sleeping with your contacts in is riskier than taking them out each night. Rigid gas permeable lenses and daily disposables have an extremely low risk of infection.
Risk increases if you do not properly care for your lenses or if you do not clean your storage case regularly.
Contact lens care
For re-usable contacts, disinfect them upon removal form the eye. This prevents harmful organisms building up on the lens. Your Dr. Randhawa will tell you about the best contact lens system and care regime for your type of lenses.
Rinse your storage case and leave it open to dry every day, and replace it every month. A dirty case is a major source of infection. Clean the storage case using a clean toothbrush and contact lens solution every week.
Do not re-use daily disposable lenses because there is no disinfecting solution for them and they are not designed for repeated use.
Extended wear lenses are specially designed for overnight wear and can be continuously worn for up to a week or a month at a time before being discarded.
Do not sleep in lenses unless advised to do so by Dr. Randhawa.
