WHAT'S NEW IN CONTACT LENSES

Silicone Hydrogel Lenses Gaining Acceptance
The latest generation of contact lenses, made of silicone hydrogel, now accounts for nearly half of all new fits of contact lenses. This new lens material provides a hyper oxygen flow to the cornea, enhancing comfort and enabling contact lenses to be worn on a daily basis, or, in certain cases, overnight for up to 30-days continuous wear. Silicone hydrogel lenses also include components that keep them moist on the eye. All major contact lens manufacturers now offer silicone hydrogel contact lenses — and some have introduced a second generation of silicone hydrogel lenses that improves comfort in dry environments like air-conditioned offices and airliner cabins. Ask your eye care professional about silicone hydrogel contact lenses.
Eye care practitioners report that many of their patients who ask about laser vision correction opt out of it. Instead of going through a costly and stressful surgical procedure to reshape their corneas, patients find that silicone hydrogel contact lenses are an appealing alternative. These lenses are remarkably comfortable, they can be worn continuously for up to a month at a time, and they remain moist on the eye while providing crisp, stable vision. Consumers who wear silicone hydrogel contact lenses say they feel like they are wearing no lens at all — the very goal they were seeking with laser vision correction.

Contact Lenses Help Aging Eyes
A wide array of new contact lens designs correct for “presbyopia,” an age-related condition that makes it difficult to see objects up close. New “multifocal” contact lenses provide a “blended” vision that is vastly improved over previous bifocal contact lenses that contained segments or rings for near or far objects, say eye care professionals. Those who wear multifocal contact lenses report that, in many cases, it’s like their “youthful vision” is restored.

Blocking Out Harmful UV Rays
Many contact lenses now include an agent that blocks out potentially harmful rays of sunlight. Ask your eye care professional which products block both the UVA and UVB radiation that are associated with higher rates of cataracts later in life.
