CONTACT LENSES
An unobstructed view

Wide variety of lenses available

Although 1 percent of contact wearers still use hard lenses, most people use one of the many newer options on the market. These include:
Daily wear soft lenses are thin polymer-plastic lenses that conform to the shape of the eye. These lenses allow oxygen (important to the health of the cornea) to pass through to the cornea. They are softer than hard contacts and more comfortable. These lenses have a shorter adaptation period and tend to stay in place better, making them a better choice for active lifestyles and sports. Special soft contacts, called toric lenses, are available to correct mild to moderate degrees of astigmatism (asymmetrical cornea). Daily wear soft lenses are not as durable as other lenses, and they don't correct some vision problems, including high degrees of astigmatism.

Rigid gas-permeable (RGP) lenses are made of hard plastic with pores that allow even more oxygen to pass through than do daily wear soft lenses. They offer excellent correction of a wide range of vision problems and are comfortable for most people after a period of adaptation: RGP lenses are easy to care for, less likely to cause infection, and more durable than soft lenses. Disadvantages: They must be worn consistently to maintain adaptation, and they slip off the center of the eye more easily.

Disposables are soft lenses available in both daily and extended-wear versions. Advantages are the same as with other soft lenses, since they are usually discarded before microbial growth or protein build-up occurs. Disadvantages are similar to those of regular soft lenses; they also may be more difficult to handle.

Extended-wear lenses. These are soft lenses approved for 6 or more days and nights of continuous wear. They have been quite popular, but recent research has caused some rethinking. "We discourage our patients from wearing any lens overnight," Dr. Baratz says. "In fact, we don't dispense extended-wear lenses for overnight use. Studies show that the risk of infection and other problems increases ten-fold with overnight wear. I don't think it's worth the risk."

Bifocals. There are two options here: One is a lens that contains two different prescriptions, like bifocal glasses. The other option is "monovision," in which the wearer uses a lens with the reading prescription in one eye and a lens with a distance prescription in the other eye. The brain adjusts to this and learns to see as if both eyes had the same correction. Dr. Baratz emphasizes that either bifocal option requires accurate and professional fitting and takes some getting used to. Not everyone is able to use bifocals.

Cleaning and hygiene

Many problems with contact lenses can be avoided by using hygienic practices:
Wash, rinse and dry your hands before handling your lenses. Use mild soap and a lint-free towel.

Handle, insert and remove lenses before applying or removing cosmetics.

Never use tap water, saliva or homemade solutions to clean or wet lenses.

Use quality lens care products according to manufacturer's directions. Don't reuse solutions.

Clean your lens case daily with sterile rinsing solution and then air dry. Replace the case every 3 months.

Warning signs

Signs of trouble may include:
Blurred or fuzzy vision, especially with rapid onset.

Pain in and around eyes.

Discharge, itching, redness or irritation of eye or eyelid.

Uncomfortable lenses.

Contact lenses offer freedom from the discomfort and worries of wearing glasses plus a cosmetic benefit important to some. Treating your contacts with care will ensure that your eyes and vision remain healthy.
