Expert’s Advice On Caring For Contact Lenses

Contact Lenses usually don't cause any problems as long as you clean and wear them the right way. Remember that people who wear contact lens are at greater risk of eye infections and cornea injuries than those who do not. When small objects are trapped inside the lens, they may scratch the eye. In other times, pinkeye or conjunctivitis may occur when the contact lenses you wear are unsafe or uncomfortable.

Symptoms of Problems
Symptoms of contact lens related problems include:
- blurred vision
- drainage
- redness
- pain
- burning sensation in the eye
- sensitivity to light or photophobia

If you experience any of these symptoms, remove the contact lenses and disinfect them. If the symptoms persist for longer than two to three hours after you have removed and cleaned the contacts, call your eye doctor. Caring for the contact lenses is one way to avoid such problems. Before you learn how to do that, let's first check out the different types of contact lenses.

Types of Lenses
There are soft and hard lenses.

• Soft Lenses
The first type is called the soft lenses. They are the lenses worn daily and removed at night for cleaning. They are reinserted in the morning. The good thing about this type is that it takes you less time to get used to it. They are, however, less durable.

There are two kinds of soft lenses:
- Extended-Wear Soft Lenses
- Disposable Soft Lenses

Extended-Wear Soft Lenses: One kind of soft lenses are the extended-wear lenses, which can be worn for up to one week continuously, day and night. It's important to note that some people are not able to tolerate this type of contact lenses because they are not regularly removed and cleaned. Eye irritation is more common with this.

Disposable Soft Lenses: The other kind of soft lenses are disposable lenses, which you wear for a week before discarding. These are preferred by more uses as there are less risks of infection with this type.

• Hard Lenses
The second type is the hard lenses. They are the conventional hard lenses made of a stiff plastic called polymethyl methacrylate (PMMA). These durable lenses can correct vision, but they are very uncomfortable as they don't mold to the shape of the eyes. It may take a while before a user gets used to wearing this type of lenses. Because they reduce the amount of oxygen that gets into the cornea, people who use them are more prone to the overwearing syndrome as well as other problems.

• Rigid Gas Permeable (RGP) Lenses
The last type is the rigid gas permeable (RGP) lenses. Made of durable plastic that transmits oxygen, RGP lenses are less durable than the ones made with PMMA, but they are a little more comfortable. They are designed for extended wear of overnight up to seven days.

Safety Tips
Follow cleaning instructions carefully.

• Keep all lenses and supplies clean. Wash hands thoroughly before handling the lens and before inserting or removing them from your eyes.

• Use the lens care system specialized for the contact lens you're wearing. Never mix products or use homemade saline solutions.

• Don't wet your lenses with saliva. Never place them in your mouth. The bacteria in your saliva can cause eye infection. Don't use tap water to rinse your lenses.

• Always rinse the lens in its storage case. Let it dry naturally.

• Insert the contact lenses before putting on make-up. Make sure you don't get any make-up on your contact lenses.

• Visit your eye doctor at least once a year to have your eyes checked.
