Contact Lens Dangers: Prevention Better than Cure

* Contact Lens Dangers* can be faced by any contact wearer. So it is
much better to find out all the possible outcomes and only after that to
make a decision whether it is worthy to order contact lenses
<http://www.contactlenses123.com/order-contact-lenses-2.html> or maybe not.

There are several complications and diseases that can be stimulated by
contact lenses and their improper care
<http://www.contactlenses123.com/contact-lens-care.html> and wearing.
The most dangerous of them is known as fungal infections that can lead
to blindness. Actually they scar cornea, that is very harmful for eyes'
health. In the worst cases patients should be operated on and have
cornea implants. Fusarium can be found in southern countries and states
more often than in northern ones. Thus residents of warmer countries
are exposed to this contact lens danger more.

Annually there are dozens of experiments carried out by researches so
that to fix a main cause of contact lens dangers. Still even now with
bulks of ultra-new devices, technologies, and medications it can be very
difficult to determine which microorganism has caused reddenness or
itchiness. To state a diagnosis one hundred percent surely, a patient
needs to do a lab test.

There are three main parts of an eye that are exposed to the key contact
lens dangers, they are an eyelid, a conjunctiva, and a cornea. And there
are up to twelve diseases that can strike lens wearers.

Eye doctors say that each year the number of contact wearers increases,
but slightly. This can be explained by the following phenomenon: a great
many people who have worn contacts for some time prefer glasses to
lenses. Such a thing can be provoked by poor perception of eyes. Some
people can't wear contacts because their eyes secrete various elements
that affects integrity and transparency of contacts. Any time you feel
discomfort or burning pain, your eyes become red or begin watering you
need to go to an ophthalmologist's.

Contact lens dangers are numerous and to avoid or minimize them, follow
your doctor's recommendations closely.

Report cites risks associated with over-the-counter cosmetic contact
lenses

SAN FRANCISCO--One patient needed a corneal transplant and another is
legally blind after wearing over-the-counter cosmetic contact lenses.
These are two of the patients discussed in a report published in the
October issue of Eye & Contact Lens, the clinical journal of the Contact
Lens Association of Ophthalmologists.

The over-the-counter contact lenses, which are illegal in the United
Stated, are not worn to correct refractive errors. Instead, they are
tinted to change the appearance of eye color or have various shapes and
designs, ranging from animal eyes to sports team logos. Problems
associated with illegally sold contact lenses were first reported by the
American Academy of Ophthalmology, the Eye M.D. Association, in July
2002. The Academy received reports from a Myrtle Beach, S.C.
ophthalmologist who treated several patients for eye problems after they
wore contact lenses purchased from local beachwear stores.

All decorative contact lens are not illegal, however, all contact
lenses, whether corrective or decorative, need to be fitted and
monitored by an eye care professional. Editor-in-chief of Eye & Contact
Lens, H. Dwight Cavanagh, MD, Ph.D., F.A.C.S., said, "This report
underscores the need to continue to view contact lenses as medical
devices. They need to be fitted and prescribed by licensed health care
professionals. As seen in this report, the unregulated sale of contact
lenses represents a grave danger to the public."

"Many people mistakenly think decorative contact lenses are just like
sunglasses. If you're not wearing the lenses to correct refractive
errors, you don't need a prescription. This is a dangerous
misconception," said one of the report's authors, Thomas L. Steinemann,
MD, of the MetroHealth Medical Center Eye Clinic in Cleveland and
associate professor of ophthalmology at Case Western Reserve
University's Department of Ophthalmology. "People who wear lenses
purchased from unlicensed vendors have been given no instructions and
often practice risky behavior. They don't clean or disinfect the lenses.
They sleep in them. They swim in them. The even swap them with their
friends."

Six patients, from 14 to 32 years of age, are discussed in the
observational case report. The patients, five females and one male,
experienced vision-threatening problems after wearing contact lenses
purchased from unlicensed vendors, including gas stations, beauty
salons, video stores, corner stores and flea markets. They did not
receive any instructions on how to properly care for or wear the contact
lenses. And ? all of them were sold individual contact lenses without a
prescription, an examination or a fitting by aneye care professional
such as an ophthalmologist. According to the case report:

* One 14-year-old patient nearly lost her eye after contracting a
serious bacterial infection. She was hospitalized for four days
and was left with a corneal scar that affected her vision. The
patient later required a corneal transplant, and will need regular
observation and treatment for the rest of her life.
* After falling asleep with her contact lenses still on, a
19-year-old woman awoke to burning and light sensitivity in both
eyes. She said she had been buying the contact lenses from
open-boxed sets without a prescription for the past five years and
had worn contact lenses continuously for up to five months on
previous occasions.
* Another 19- year-old-woman, who complained of light sensitivity
and burning in her right eye, said she purchased her
over-the-counter contact lenses from gas stations, hair salons and
corner stores for years, along with her friends, teenage sisters
and mother.
* A 30-year-old woman continued to wear her contact lenses, despite
experiencing worsening symptoms over a two-week period that
included right eye pain, tearing, light sensitivity and redness.
In an attempt to relieve the redness and lubricate the lenses she
used over-the-counter eye drops before finally seeking medical
treatment.
* A 32-year-old man scratched his cornea while trying to remove
costume contact lenses. He had developed painful inflammation from
a lens that did not fit. He had purchased the contact lenses for
Halloween a week earlier at a flea market. This required multiple
treatments over several weeks.
* A 24-year-old woman became legally blind from corneal scarring in
one eye, after she developed conjunctivitis (pink eye) and was
treated for herpes simplex and bacterial keratitis. She reported
wearing disposable contact lenses for approximately six months,
often sleeping in them.

The report says the demand for decorative contact lenses continues to
increase, particularly among teenage girls and young women, with
consumers spending approximately $180 million on them so far. Colored
contact lenses are one of the fastest growing segments in the contact
lens market. Because of the growing market, the report states: "American
young people remain at risk as a major target of the unauthorized sale
ofdecorative contact lenses."

Problems that may result from this risky behavior include corneal
abrasions, epithelial keratitis, infectious ulcers and the blinding
Acanthamoeba organism. Although no cases have been documented, the
report also suggests HIV transmission is a potential risk among those
who exchange their contact lenses with others.

Report from Asian News International brought to you by HT Syndication.

Washington, Oct. 21 -- (ANI): A Spanish study has revealed that contact
lens cases are often contaminated with Acanthamoeba which cannot be
killed by normal contact lens solution.Published in the Journal of
Medical Microbiology, the study report describes Acanthamoeba as one of
the most common types of protozoa in soil, which is often found in fresh
water. The researchers behind the study say that most species eat
bacteria, and some can cause infections in humans. They have revealed
that one of the diseases caused by Acanthamoeba is called amoebic
keratitis, an infection of the eye which is very painful and can

New Contact Lens and Case Timer Solves Widespread Problem

ST. LOUIS, April 10 /PRNewswire/ -- There are over 38 million contact
lens wearers in the U.S. and children are the fastest growing segment.
The contact lens industry is enjoying great success, but there is danger
growing under those lenses.

Danger in the form of hard to pronounce words like fusarium keratitis
and acanthamoeba keratitis. These are nasty words that are causing eye
health complications from minor eye infections to blindness. Thousands
of patients will visit their doctors today, unnecessarily.

And the culprit? Up to 80% of all complications are traced back to poor
patient …

Jadi tdk hanya particle tetapi bacteria juga menjadikan contact lenses
berbahaya.

Sehingga tdk sesederhana itu bila anda ingin merawat organ penting mata anda
