CONSIDER CONTACT LENS !

With over 31 million people wearing contact lenses in the United States alone, it is obvious that contact lenses are the number one choice for many people with vision correction needs. After all, contacts provide close to natural sight, and there are so many different lenses available for a wide variety of needs and preferences.
The flexibility and convenience that contact lenses provide are leading more and more people to contacts as science provides us with greater options in contact lens wear. And because there are so many options, it is important to discuss the matter fully with an eyecare professional, who will consider your overall vision problems, the health of your eyes, and your specific visual needs and motivations.

HOW OLD IS OLD ENOUGH?

How old is "old enough" for contact lens wear? This is one of the most frequently asked questions concerning vision correction the CLC receives.
Dr. Barry Weiner, past chairman of the American Optometric Association's contact lens section and CLC member, says, "There are no hard and fast rules with children and lenses." I've fit a child as young as 8. Granted, it was a very mature 8-year-old. So much depends on the responsibility level of the child. There are 14- and 16-year-olds--in fact, 20-year-olds--that I wouldn't fit with contacts, because I simply didn't think they were ready."
It is important for an eye care professional to assess a child's vision correction needs and to discuss the child's capabilities and maturity level when considering contacts. Personal wear and care regimens may depend upon the type of contact prescribed, the nature of the vision problem being corrected, and the child's unique eye chemistry.
Regardless of the type of lens one wears, lens care is now easier and more convenient than ever before, and has become a possibility for many children. Basic lens care includes cleaning, rinsing, disinfecting, and storing to keep lenses clean, comfortable and free from bacteria. The CLC urges parents and children alike to follow specific instructions prescribed by their eye care professionals. For more information, see our "Safety Tips".
Advances in contact lens technology are even enabling a significant number of infants and toddlers to cope better with serious eye problems. Babies born prematurely are at a high risk of blindness because their retinas are not completely developed at birth. Approximately 4,000 preemies are affected by this problem each year. While surgery can protect their vision, this procedure often leaves them either very nearsighted or very farsighted. Contact lenses can provide them the best vision possible and even help their own vision develop better. Spectacles are not a practical alternative for this group.

GENERAL SAFETY TIPS FOR CONTACT LENS WEARERS

  • Visit a reputable eyecare professional for a complete eye examination every 12 months or more frequently if directed by your eyecare professional.
  • Use only contact lenses if they are FDA-approved and only if prescribed by a licensed eyecare practitioner. Ask your practitioner whether the FDA has cleared the product.
  • NEVER swap contact lens with another person.
  • Don't wear lenses longer than prescribed, nor when sleeping unless otherwise directed.
  • If eyes become red or irritated, remove the lenses immediately and consult your doctor. Don't try to brave the irritation.
  • Replace contacts as recommended by your eyecare professional because they wear out over time. Throw away disposable lenses after recommended wearing period.

CLEANING AND SOLUTIONS SAFETY TIPS

  • CRD: Cleanse, Rinse, Disinfect your lenses after removal and before wearing them again. Enzyme cleaners and cleaning solutions alone can not substitute for disinfecting, although there are multipurpose products that can perform many of these functions if used as directed.
  • Wash and rinse your hands before handling your lenses. A non-perfumed hand soap is recommended.
  • Never use saliva on your lenses.
  • Never use non-sterile homemade saline, distilled water or tap water for any part of your lens care regimen.
  • Know your solution. Solutions cannot always be mixed. Use products recommended by your eyecare professional. Not all solutions can be used for all contact lenses.
  • Solutions can become contaminated during use. Do not let the bottle tip touch any surface including your contact lenses.
  • Clean, rinse and air-dry your lens case each time lenses are removed. Contact lens cases can be a source of bacterial growth.

What is Rigid Gas Permeable (RGP) Contact Lenses ?

Rigid gas permeable lenses are rigid contact lenses made of oxygen-permeable polymers. Initially developed in the late 1970s, and through the 1980s and 1990s, they were an improvement over prior 'hard' lenses that restricted oxygen transmission to the eye. Rigid lenses are able to replace the natural shape of the cornea with a new refracting surface. This means that a regular (spherical) rigid contact lens can provide good level of vision in people who have astigmatism or distorted corneal shapes as with keratoconus. However, they require a period of adaptation before full comfort is achieved

What is Soft Lenses ?

Hard" lenses were the original contact lenses made several decades ago from a plastic called PMMA. For a long time they were the only kind of lens but they are seldom used anymore as they have several drawbacks and have been superseded by "Rigid" lenses. In fact, when people say hard lenses they are most likely referring to the gas permeable type. Gas permeable lenses are similar to hard lenses in design and appearance, however as the name suggests the material they are made of is permeable to gases (most importantly Oxygen and Carbon Dioxide) whereas PMMA is completely impermeable to gases. "Soft" contact lenses are completely different in that they are slightly larger, flexible and made of materials which soak up water. In fact the uptake of water is what allows soft lenses to transmit Oxygen to the cornea, the plastic itself being impermeable. The water also gives them their flexibility.
if you let a soft lens dry out, it does become quite brittle.

Caring for Soft Contact Lenses

The Basics of Soft Contact Lens Care: Clean, Rinse and Disinfect

  • Wash your hands so that you don't transfer dirt and germs to your eye. Try to avoid moisturizing soaps, as they are not good for contact lenses. Dry your hands with a lint-free towel.
  • Remove one lens and clean it with the recommended solution. Cleaning removes eye-produced buildup, cosmetics and other debris that impairs lens comfort. Some products require you to rub the lens in the palm of your hand with a few drops of solution, while others just require rinsing.
  • Rinse the lens again to remove the loosened debris, making sure to take as long as the package directs: rinsing is an important step.
  • Place the lens in your clean lens case or lens holder and fill with the appropriate solution for your soaking and disinfecting system. Disinfecting kills microorganisms on the lens. Disinfection time varies from product to product; check the package for details.
  • Repeat steps two through four for your other lens.

Beyond Clean, Rinse and Disinfect

  • Protein.
    Depending on what kind of contact lenses you wear and how much protein your eyes deposit on your contacts, your doctor may recommend you use a product for protein removal. While cleaning them does remove some protein, it can still build up on your lenses and make them uncomfortable. That's why the longer you wear lenses before replacing them, the more likely you are to need a protein remover. For example, if you wear disposables, you probably won't need one, but if you replace your lenses about once a year, you definitely will. Products for removing protein include enzymatic cleaner and daily protein removal liquids.
  • Eye Dryness and Irritation.
    Use contact lens eyedrops to lubricate your eyes and rewet your lenses.
  • Eye Sensitivity and Allergies.
    A small percentage of patients develop an allergy to the chemicals present in contact lens solutions. If this is the case with you, you don't need an additional product: you just need to switch products to those marked "preservative-free."

Contact Lens Care Must-Knows

Once you've decided which product you'd like to try, discuss your plans with your eye doctor. Don't switch brands until you determine that the new brand is compatible with your other products and with your contact lenses.

Regardless of which care regimen or brands you use, remember:

  • Never touch solution bottle tips to any surface, including your body: the solution can become contaminated.
  • Avoid getting tap water on your contact lenses and accessories, as it can carry a microorganism called Acanthamoeba that causes serious eye infections. While regular contact lens disinfection procedures do kill Acanthamoeba, they typically don't kill its cysts.
  • Remember to clean your contact lens accessories (lens case, cleaning/disinfecting devices, enzymatic cleaner vials and so on) as directed.
  • Lens cases can be rinsed with hot tap water and dried when not in use.
  • Throw out your contact lens case once a month, or as directed, to reduce your risk of infection.

Most importantly, clean and disinfect your contact lenses once a day (those with extended wear contacts should clean and disinfect them when they take them out, unless the lenses are scheduled to be discarded). Not only will your eyes be safer and healthier, but your contact lenses be more comfortable to wear, too.

What is PARAGON CRT(Corneal Refractive Therapy) ?

Sleep your way to Great Vision !

Correct your vision while you sleep with safe, non-surgical Paragon CRT therapeutic lenses, and enjoy great vision 24 hours a day, without the hassles of glasses and daytime contacts.

Paragon CRT is a specially designed oxygen permeable therapeutic contact lens used in Corneal Refractive Therapy. Corneal Refractive Therapy is a sophisticated, non-surgical process, which reshapes the cornea while you sleep. You remove the lenses when you awake and are able to go throughout the day without any other correction.

Corneal Refractive Therapy with Paragon CRT

Now you can be free of daytime contact lenses and glasses during your daily activities without undergoing surger and enjoy great vision! Recent clinical research combined with the latest corneal surface mapping technology, computerized manufacturing and space age oxygen-breathing materials have brought new science to corneal reshaping.

Corneal Refractive Therapy is a non-surgical process clinically developed to reshape the cornea while you sleep. The result is the temporary correction of myopia with or without moderate astigmatism.

Similar in appearance to standard contact lenses, Paragon CRT therapeutic lenses gently reshape the corneal surface during sleep and provide clear, natural vision when the lenses are removed upon waking.

Because Paragon CRT offers freedom from glasses and the hassle of wearing contact lenses during the day, this leading-edge technology can enhance the lifestyle of those requiring vision correction. Active individuals can freely participate in sports without the interference of glasses or bother of contacts. Eye irritation or dryness, sometimes associated with contact lens wear due to outside dust and pollutants, is eliminated.

What is PARAGON CRT(Corneal Refractive Therapy) ?

Let's understand how Corneal Refractive Therapy with Paragon CRT works to correct Myopia.

In the myopic eye, the focusing power is too great. Light focuses in front of the retina, making distant objects appear blurry. When eyeglasses or contacts are worn, light is focused on the retina so you can see clearly.

Laser surgery is another way to correct myopia. It permanently alters the cornea and corrects the focal point, producing clear vision.

Today, Corneal Refractive Therapy provides a new option for patients. Paragon CRT lenses correct myopia, with or without low or moderate astigmatism, by gently reshaping the cornea while you sleep.

When the Paragon CRT lenses are removed in the morning, the treated cornea allows light to focus on the retina. The result is clear, natural vision for all or most of your waking hours.

How likely is it that Paragon CRT will work for me ?

Of the 159 eyes targeted for 20/20 vision (who had this acuity with their best spectacles), 59% obtained 20/20 or better without other correction and 92% obtained 20/40 or better at 9 months. (20/40 vision is the acuity required in most states to drive without glasses). 67% Of the subjects obtained 20/20 vision in at least one eye (their better seeing eye) and 94% achieved 20/40.

Disposable Contact Lenses

Introduced in 1987, disposable contacts are designed to be worn for a specific period of time, then thrown out and replaced with a fresh pair of lenses. Disposables are now the most common type of contact lenses. Many eye care practitioners and consumers favor disposable contacts because of their health and convenience benefits.

It's important to understand the terminology:

  • Disposable lenses = replaced every two weeks, or sooner
  • Frequent replacement lenses = replaced monthly or quarterly
  • Traditional or reusable lenses = replaced every six months or longer

The term "disposable" often collectively refers to both disposable and frequent replacement lenses.

How Different Are Disposables from Regular Lenses?

Even before the advent of disposable lenses, it was well known that frequent lens replacement was a healthy thing to do. Problem was, contacts were too expensive to discard very often ? so various cleaning solutions and devices were used to prolong the life of the lens. Then contact lens manufacturers developed new manufacturing methods to produce high-quality lenses in greater volume, at lower cost. These advances led to lower lens prices, making it affordable to replace lenses more often. Some of today's disposable lenses are made of the same materials as traditional lenses; other disposables are made from new materials developed especially for disposability.

Colored Contact Lenses

Colored contact lenses can add some interest to your vision correction. In fact, some people wear them as an accessory even people who don't need contacts to see better! If you do need contacts to correct your vision, the ability to buy colored ones can make being nearsighted a bit more fun. Here's some tips on how to choose colored contacts.

Contacts have come a long way from the hard contact lenses that first appeared after World War II. In recent times, there has been many advances in comfort and quality. From the soft contacts with the added comfort to disposable contacts with the added convenience, contacts have been a reliable method of vision correction for over 50 years.

One of the more fun advancements in contact lenses has been the colored contact lens. With colored contacts you can completely change the color of your eyes, or simply add a tint to the color you already have. You can have a collection of colors so that you can have blue eyes when it suits you and green eyes on the other days. You can even change your eyes to a striking violet color!

There are 4 different types of colored contacts and these contacts are available for wearers who need no eye correction and also for those that have astigmatism as well as those that need bifocals. They also come in disposable wear as well. Visibility tint contacts are more for convenience than for changing eye color. These contacts are lightly tinted and are mainly s that you can see them easily. Anyone that has ever dropped a contact, will agree that trying to find them is almost impossible, but visibility tints make this much easier. This tinting does not really change the color of your eye.
