Focus Night and Day Contact Lenses
Do you hate the whole ritual of removing and cleaning and putting your contact lenses back in every day? Do you love the vision correction without the glasses - but hate the hassle of daily disinfecting? Extended wear contacts may give you the all the advantages of contact lens wear, without the daily hassle - and without the same risks of infection that were related to them in the past.
What is extended wear contact lenses?
Extended wear contact lenses are designed to be worn for extended periods of time without removal and disinfections, including during sleep. Like all soft contact lenses, they are made of a gas permeable plastic and water to allow them to mold comfortably and float on the surface of the cornea. Your eyes need oxygen to help clean and protect them from infection. Normal contact lenses cover the cornea and reduce the amount of oxygen that reaches the eyes. When oxygen can't reach the eyes, or is greatly reduced, a perfect growing bed for bacteria is the result, and the bacteria lead to infections. That's why conventional contact lenses need to be removed and disinfected every day. Extended wear lenses are designed and made of far more permeable materials that allow the eyes to 'breathe' easier, allowing you to keep them in the eye for longer periods without the high risk of infection.
What are Focus Day and Night contact made from?
Back in 1981, the Food and Drug Administration approved soft contact lenses for
extended wear of up to 30 days. Within a short time, reports of increased eye
infections and heightened risks of eye damage prompted the FDA to reduce the maximum
length of wear time for extended wear lenses to 7 days. That's how things remained
for nearly twenty years.
The benefits of Focus Night and Day Contact
The benefits of Focus Night and Day extended wear contact lenses are obvious. If you
play sports, you'll have the advantage of improved vision without worrying about glasses
slipping off, falling or getting broken. According to a study by a major school of
Optometry, Night and Day lenses can be appropriate for pre-teens as young as 11 years
old. Any mother who has had to frequently replace lost or broken eyeglasses knows what
a benefit that can be! In addition, extended wear lenses are being touted as an inexpensive
alternative to lasik refractive eye surgery. They give the same degree of vision improvement
around the clock without the risks and expense of surgery.
Who should wear Focus Night and Day lenses?
According to Ciba Vision and ophthalmologists worldwide, 9 out of 10 consumers who wear
contacts can probably wear the new Focus Night and Day lenses, but it's a decision that
has to be made by an eye care professional. Certain conditions can rule out the use of
extended wear contact lenses. If you have an eye infection or inflammation, an eye disease,
eye injury or 'dry eyes', you may not be able to wear extended wear lenses. Some allergies
and medications, as well as some chronic conditions may also prevent you from wearing lenses
for extended periods.
