Precaution while using contact lenses
What Are Contact Lenses
. Contact lenses are medical devices worn directly on the cornea of the eye. Like eyeglasses, contact lenses help to correct refractive errors and perform this function by adding or subtracting focusing power to the eyes cornea and lens. Contacts provide a safe and effective way to correct vision when used with care and proper supervision. They can offer a good alternative to eyeglasses, depending on your eyes and your lifestyle. Over 24 million people in the United States now wear contact lenses. For certain conditions, contact lenses may be considered medically necessary.
Types of Contact Lenses
. These are the most common type of contact lenses currently prescribed. These lenses are made materials that incorporate water, which makes them soft and flexible and allows oxygen to reach the cornea. 1Daily disposable lenses: Although generally more expensive, they carry a lower infection risk. Two week or monthly disposable lenses: for daily wear. 2Toric contact lenses: Correct moderate astigmatism. Bifocal contact lenses: can be helpful for patients that need reading and distance correction but may not be right for everyone.
. These lenses are also known as RGPs. They are rigid or hard lenses made of plastics combined with other materialssuch as silicone and fluoropolymersthat allow oxygen in the air to pass directly through the lens. For this reason, they are called gas permeable.
. Dailywear lenses should never be worn as extendedwear lenses. Misuse can lead to temporary and potentially sight threatening damage to the cornea. People who wear any type of lens overnight have a greater chance of developing infections of the cornea. These infections are often due to poor cleaning and lens care. Improper over wearing of contact lenses can result in intolerance, leading to the inability to wear contact lenses.
Gas permeable lenses
. Gas permeable lenses can potentially scratch the cornea if the lens does not fit properly or if the lens is worn while sleeping. They are also more likely to slide off the cornea and become hidden under the lid. Gas permeable lenses traditionally had a reputation for popping out of the eye. Newer lens designs have minimized the chance of losing a contact even during vigorous exercise.
Soft extendedwear contacts
. Gaspermeable lenses and soft extendedwear contacts are the most likely to have protein buildup and cause lensrelated allergies. Protein buildup results in discomfort, blurring, and intolerance to the lenses. Thus, nightly disinfection becomes imperative and you mayneed special cleaning solutions to dissolve the protein.
Who Should NOT Wear Contact Lenses
. Most people who need vision correction can wear contact lenses. Among the conditions that might keep you from wearing contact lenses are:1Frequent eye infections. 2Severe allergies. 3Dry eye (improper tear film). 4A work environment that is very dusty or dirty. 5Inability to handle and care for the lenses properly.
Are Contacts for You
. Whether or not contact lenses are a good choice for you depends on: 1Individual needs and expectations. 2Patience and motivation during the initial adjustment period to contact lens wear. 3Adhering to contact lens guidelines for wear, disinfecting, and cleaning. 4Diagnosis and treatment of conditions that may prevent contact lens wear.
How to Care for Your Lenses
. Contact lenses must be properly cleaned and disinfected when you remove them to kill germs and prevent infections. All contact lens cases should be cleaned daily and it is recommended that you replace your case every three months. Never reuse your contact lens solution. Dispose of contact lens solution in the lens case after each use and let the case air dry. Do not put your lens in your mouth and then in your eye. Never use homemade cleaning solutions as they have been linked to serious eye infections. Any eye drops, even nonprescription ones, can interact with all types of contact lenses. Use the prescribed brand of solution or check with your optometrist before changing brands.

Safest medical devices
. Contact lenses are one of the safest medical devices when worn responsibly, says Thomas L. Steinemann, MD, a professor of ophthalmology at Case Western Reserve University in Cleveland and a spokesperson for the American Academy of Ophthalmology. While contact lens use is safe, not caring for contact lenses properly or failing to follow contact lens safety rules can lead to serious problems. Contact lenses can be a potential point for infection, says Dr. Steinemann. No matter how careful you are, germs are on our hands, eyelids, everywhere. When germs such as bacteria and fungi are on the contact lens, they can invade the eye.
Get a contact lens prescription from an eye doctor
. Have your lenses fitted by a qualifiedeye care professional, says Steinemann. Also be sure to get instruction on proper lens care. Make sure that the contact lens is on the cornea of the eye. Cover the opposite eye, and if your vision is blurry, inspect the upper area of your eye by lifting the upper lid and looking into a mirror, and the lower area by gently pulling down the lower lid.
Dont wear contact lenses overnight
. When you close your eyes with your lenses in place, youre reducing oxygen, says Steinemann. The surface of the eye becomes more vulnerable to infection. Also, you have a lens being closed against the eye any germs on the lens are being slammed against the cornea.
Dont wear your contact lenses in the shower or while swimming
. Lakes, rivers, sea water, swimming pools, and even tap water can all harbor an organism calledacanthamoeba, which can cause eye infection. Wearing contact lenses while swimming, showering, or doing other waterrelated activities can lead to seriousacanthamoebainfections of the eye.
Dont reuse contact lens solution
. You may think youre saving money by doing so, but the disinfecting capability of the solution is gone, says Steinemann. Use fresh solution every time you store your lenses in their case. There are two common methods for removing contacts. Follow the one that your doctor recommended, and if either of these methods are difficult for you, your doctor can recommend another method of removal.
Dont use saline solution for contact lens cleaning or disinfection
. Saline solution is simply sterile salt water. It will not clean or disinfect. Be sure to choose a solution that includes disinfectant. For the pinching method, look up, slide the lens to the lower part of the eye using the forefinger, pinch the lens between the forefinger and thumb, and remove the lens. The pinching method should not be harmful, your fingernails should not touch the lens or your eye.
Replace your contact lens case every two to three months
. Lens cases get dirty, just like a toothbrush, says Steinemann. The forefinger and thumb method means you dont have to actually touch your eye. Place your hand or a towel under your eye to catch the lens. Place your forefinger on the center of the upper lid, and your thumb on the center of the lower lid and force a blink. The lens should fall out onto your hand or the towel.
Never use saliva as a wetting agent
. Your mouth is one of the dirtiest places in your body, says Steinemann. After you remove the contact, follow care instructions given to you by your doctor, or on the case of the contact. If they are single use contacts, discard the lens immediately. If they are for multiple use, immediately follow care instructions.
Take out your contacts if they are bothering you
. It seems like common sense, but it can be easy to ignore irritation when youre busy or distracted. Never put up with irritation, as it could be sign of an infection or other problem. Make sure to clean, rinse, then disinfect your lenses after you remove them. Cleaning and rinsing the contacts removes any film, dirt, and anything that may have accumulated while you were wearing them. Disinfecting them is important for the elimination of germs.

Follow these instructions carefully as failure to do so can result in serious problems, such as infection or damage to your eyes.
To remove lenses
. After you take out each contact lens from your eyes, gently rub with solution. Then rinse each lens with fresh solution before storing them for disinfection; be sure you squeeze enough solution into each case compartment to cover each lens. Even if the packaging of the solution you use reads no rub, you should still clean each lens to remove any germs, says Steinemann.
To put in lenses
. After disinfecting your contact lenses according to the product directions on your solution bottle andbeforeyou put them back in your eyes, rinse off each contact lens with fresh solution. Discard used solution, rinse out the lens case with fresh solution (not water), and let the case air dry.

You should continue to use UV absorbing eyewear. Longterm exposure to UV radiation is one of the risk factors associated with cataracts. Exposure is based on a number of factors such as environmental conditions (altitude, geography, cloud cover) and personal factors (extent and nature of outdoor activities). UV blocking contact lenses help provide protection against harmful UV radiation. However, clinical studies have not been done to demonstrate that wearing UV blocking contact lenses reduces the risk of developing cataracts or other eye disorders.

. Always be sure the lens is on thecornea(in the center of your eye) before attempting to remove it. Determine this by covering the other eye. If vision is blurred, the lens is either on the white part of the eye or it is not on the eye at all. To locate the lens, inspect the upper area of the eye by looking down into a mirror while pulling the upper lid up. Then inspect the lower area by pulling the lower lid down.
For Daily Disposable Wear
. There is no cleaning or disinfection needed with your contact lenses if they are prescribed for daily disposable wear.
