Contact Lens Basics

Contact Lens Solution


In general, contact lens solution is used to take good care of your contact lens. Contact lenses are thin, finely crafted plastic discs designed to fit over the cornea of the eye, usually to correct vision problems caused by refractive error. They are held in place by a natural layer of tears on the surface of the eye.

In addition, contact lenses provide better peripheral vision and virtually eliminate the image distortion sometimes caused by eyeglasses. Contact lenses are now available for the correction of most vision problems caused by refractive defects of the eye including nearsightedness, farsightedness, astigmatism, and presbyopia.

There are several types of contact lenses- such as bifocal contact lenses, colored contact lenses, cosmetic contact lenses, disposable contact lenses and even custom contact lens. Remember to use good contact lens cleaner for contact lens cleaning. Some general guidelines should be followed for all lens types. Always wash your hands before removing or inserting the lens.

There are several types of cleaning solutions available. You should use the appropriate contact lens solution recommended to be used with your contact lenses. The types of solutions are as follows:

Cleaning solution: A cleaning solution removes dirt, mucus and debris that accumulate during lens wear. Lenses should be rubbed gently for a few seconds to loosen the debris and then rinsed with a saline solution.

Rinsing solution: After cleaning, lenses should be rinsed with a commercial saline contact lens solution.

Disinfecting solution: The disinfecting solution inhibits and/or kills bacteria and other harmful micro organisms on the lenses that can cause eye infections. After cleaning and rinsing lenses, they should be stored overnight in a storage case filled with fresh disinfecting solution.

Multipurpose solution: A combination solution designed to clean, rinse and disinfect contact lenses.

Rewetting solution: Drops that lubricate the lenses while they are being worn. They can be used all day to keep the eyes moist and to enhance the comfort of wearing contact lenses.

All solutions used for cleaning, rinsing, and disinfecting contact lenses should be discarded after the expiry date on the bottle. To avoid contact lenses dry eyes, always follow the opthalomogist's recommendations for cleaning and caring for your lenses.

Except for contact lenses that are worn for a short, continuous period and then thrown away, all contact lenses require cleaning, disinfecting, and rinsing on a daily basis. In fact, a contact lens that has been removed from the eye should never be reinserted without cleaning and disinfecting. Never sleep in contact lenses unless approved by opthalomogist. Whenever a lens is removed, it should be cleaned, rinsed, and disinfected before being worn again. Be careful to protect your lenses from lotions, creams, and sprays. Lenses should always be inserted before applying makeup and removed after makeup has been removed.
