Can artificial tears be safely used to re-wet contact lenses?

In some cases, eye drops that are designed to treat dry eyes may have formulations that are incompatible with contact lens wear. For this reason, contact lens wearers are well-advised to use only the contact lens solutions specifically recommended by their optometrist or ophthalmologist.

But a new study conducted by Allergan (Irvine, Calif.) has found that one of the company’s artificial tear products appears to work well as a contact lens lubricant. In fact, when compared with Allergan’s own brand of contact lens rewetting drops, the artificial tear actually outperformed the rewetting drop at improving contact lens comfort. Read more…

A new survey from the Asthma and Allergy Foundation of America (AAFA) indicates that fall is one of the most troublesome times of year for people with eye allergies.

Although the springtime is well-known as allergy season, “the fall brings new allergy triggers that are not prevalent in the spring, such as ragweed,” according to the AAFA.

During this time, contact lens wearers with allergies may experience contact lens discomfort as allergens build up on their lenses over time. Symptoms may include ocular itching, redness and tearing.

Studies show that daily disposable contacts can be a more comfortable option than contacts replaced every two weeks or more for allergy sufferers, the AAFA says. For this reason, Johnson & Johnson Vision Care, Inc., maker of 1 Day Acuvue Moist brand contact lenses, is supporting the AAFA’s new, educational brochure called “Eye Health and Allergies.”

The free brochure provides “vital allergy season advice for the nation’s 40 million contact lens wearers” and includes a trial pair certificate for 1 Day Acuvue Moist contacts. To download the brochure, visit the AAFA website.

If you wear contact lenses and suffer from seasonal allergies, you may be tempted to give up on your contacts. But there are a number of things you can do to decrease allergy symptoms and increase your contact lens comfort.

In a recent issue of Contact Lenses Today, Joel A. Silbert, OD, director of Cornea and Specialty Contact Lens Services at Pennsylvania College of Optometry (Salus University, Philadelphia, PA) offered several tips to help people with allergies stay in their contacts. Dr. Silbert recommends:

• Wear wraparound, close-fitting sunglasses to keep pollen and other allergens away from your eyes as much as possible.
• Wear daily disposable contacts. Because you discard these lenses after a single day of wear, you don’t have to worry about lens deposits building up on your contact lenses day after day.
• If you can’t wear disposable lenses, consider modifying your daily lens care and how you use contact lens solutions. If you use a “no-rub” multipurpose solution, for example, rub the lenses under a stream of the solution to more effectively clean the lenses. If you are sensitive to preservatives, consider switching to a hydrogen peroxide lens care system. 
• Avoid extended wear contacts. Wearing these lenses continually day after day can worsen your allergy symptoms.
• Avoid rubbing your eyes, which also will make your symptoms worse. Use cold compresses to relieve itching instead.
• Lubricate your contacts frequently with rewetting drops. Using eye drops frequently will rinse away allergens and keep them from accumulating on your lenses. 
• Drive with your windows closed and the air conditioner (AC) on. Many newer automobiles have AC filters that help trap pollen and other allergens.
• Avoid early-in-the-day outdoor activities when pollen levels are highest, and (if possible) leave the lawn mowing to someone else.

Depending on the severity of your allergies, prescription medications also may be needed to reduce allergy symptoms and improve your contact lens comfort, adds Dr. Silbert. See your ophthalmologist or optometrist for details about the best medical options for your particular needs.

A new survey by the Asthma and Allergy Foundation of America found that allergy symptoms negatively influence contact lens wear, reports Optician Online.

Of the more than 800 people surveyed, two out of every three said wearing contacts is uncomfortable when they have allergy symptoms such as itchy, red and watery eyes. About 45 percent of the survey respondents reported wearing their contacts less often and 12 percent said they ceased wearing contacts when suffering from eye allergies.

Mike Tringale, the foundation’s director of external affairs, noted that wearing contacts less frequently “creates a wide range of emotions among allergy sufferers.” When contact lens wearers use glasses instead of contacts, 37 percent report feeling less attractive, 29 percent feel less confident and 26 percent say they are less able to perform activities as well than when they are wearing contacts.

According to the Medical Clinics of North America, nearly half of US residents have allergy symptoms, and 75 percent of those symptoms affect the eyes. Allergies can trigger pink eye and other problems. It’s recommended that allergy sufferers speak with their eye doctor about disposable contact lenses and eye drops to help relieve symptoms, which will ultimately help with contact lens comfort.
