Contact lenses must be properly cleaned and stored to prevent infection and irritation of the eyes. Proper handling will also prevent damage to the contact lens.
These instructions are for soft contact lenses, the most common kind used.
Certain substances can build up on contact lenses which causes damage to the lens and irritates the eye. Avoid aerosols, powder-type make-up, or other substances that might get on the lens and cause irritation. If you do use these materials, use them before placing your contacts in.
Wash your hands before handling your contacts or touching your eyes.
To properly disinfect the lenses:
Saline solution has a special balance of electrolytes that match the fluid in the eye. Regular water can change the balance in the lens and irritate the eye. Do not use water cleaning or storing contact lenses. Avoid wearing contacts in pools or hot tubs. Do not use saliva to re-wet your contacts. Saliva is not sterile.
Maintenance and storage of lenses:
Contacts can become dry or become dirty while wearing. If the contacts are irritating, use re-wetting drops or saline to rinse your lenses. If the contacts continue to irritate your eyes, remove the contacts and let your eyes rest.
Q. Are multipurpose lens care solutions better than single purpose solutions?
A. Not necessarily. The type of lens care products you use depends on the type of lenses you have and what your doctor advises. Be sure to follow the product directions exactly.
Q. I recently switched from hard contacts to soft. Can I continue to use the same lens care solutions for the soft contacts that I have been using for the hard?
A. No. The chemicals used to clean and sterilize hard contacts are different from those used for soft contacts. If you use your hard contact solutions to care for your soft contacts, you will damage the soft lens.
Q. Should I consider a hydrogen peroxide based cleaner?
A. Some cleaner chemicals can cause irritation in the eye. Your doctor may recommend a hydrogen peroxide solution, it tends to cause less irritation. However, you have to use care with this solution because it is a weakened form of hydrogen peroxide. You cannot put the lens in your eye immediately after the lens is in contact with the solution. The solution should not be used to rinse the lens. It needs to be used in a special container that converts the hydrogen peroxide solution to a harmless solution. Follow the instructions provided by the manufacturer.
