Although contact lenses are one of the most fantastic vision correction techniques that have brought convenience and comfort to millions around the world, their improper use and maintenance can result in corneal damage and other problems. Experts maintain that most of these risks are due to improper care of the lens, often out of ignorance.
According to Dr. Alpa Atul Poorabia, an Ophthalmologist at Apollo Spectra Hospitals, Hyderabad, knowing how these issues can develop and ways of preventing them becomes very important in the interest of healthy eyes.
What are some risks of using contact lenses?
- Infections: One of the common risks associated with contact lens wear is the risk of infection. When the lens is not properly cleaned, it may pick up bacteria and fungi, which are very harmful to the cornea—the clear front part of the eye. The infection will then manifest such symptoms as redness, pain, discharge, and blurred vision.
- Corneal Abrasions: Contact lenses may scratch the cornea, which may be due to poor fitting or rough handling. An even minor scratch may become very irritating and could lead to serious complications if it is not attended to properly.
- Reduced Supply of Oxygen: The cornea derives its oxygen supply directly from the air; it does not receive oxygen supply through blood vessels. The contact lenses may reduce oxygen supply to the cornea, which is especially true when they are worn for a longer period than necessary. This may cause vascularization of the cornea due to the oxygen deficiency, and the cornea must be perfectly clear at all times for clear vision.
Tips for safe contact lens use
- Maintain Cleanliness: Hygiene is the key for handling contact lenses. Always wash your hands with soap and water before touching your lenses because your hands may
transfer bacteria and other impurities to them. Use approved cleaning solutions on your lenses and follow their instructions in order to avoid infections. - Follow the Wear Schedule: Wear your lenses for the time recommended. If your lenses are for daily wear, remove them before bedtime. Do not sleep in lenses unless they are specifically approved for overnight wear and your eye care professional has given approval. Unapproved extended wear decreases oxygen to the eyes and increases
complication rates. - Avoid water exposure: Water could be holding many bacteria that can contaminate your lenses. Always remove the lenses before swimming, showering, or using hot tubs in
order to prevent the contact of the water with the lens. Be cautious even when you are washing your face to avoid any kind of splashing of water over the lenses. - Routine Checkups: Plan your regular visits to an eye care professional for proper fitting of lenses and their appropriateness for the eyes. A regular checkup will thus detect any complication at an early stage; hence, timely adjustments to protect the corneal health.
“By following these guidelines and being aware of contact lens dangers, you will be able to help preserve healthy eyes and avoid some problems. Do remember that your eyes are both vulnerable and indispensable; treat them with respect. Seek an eye specialist opinion immediately, if you have any redness, discomfort or reduced vision with contact lenses,” Dr. Poorabia told Financial Express.com.
Don’t wear contact lenses till your eye specialist give green signals, he added.
