An eye sty is believed to be caused by some debility in the system. It can even be caused due to blockage of glands by dirt or refraction error. A sty in the eye is usually a harmless development and can be treated at home. Styes may be treated by making a decoction (prepared from the roots, seeds, stems and other parts of the plants that are boiled in water) of eyebright and chamomile, to help reduce the inflammation.

Sometimes, the infection disappears quickly, without forming into a red swelling. But other styes worsen rapidly until the eyelid swells up. Eye stye occurs when staphylococcal bacteria infect one of the tiny glands at the base of the eyelid hairs and then becomes inflamed. It is commonly found as small bumps on the base of eyelids.

Stye is often accompanied with certain complications, such as there may be spread of infection to other eyelash follicles. There may also be spread of infection to the tissue of the eyelid, which is known as Eyelid cellulites. The symptoms of styes may resemble other conditions or medical problems.

Some Eye Sty treatment Tips

1. Do not touch your eyes when you are gardening or cooking.

2. You should protect your eyes from air pollution and dust.

3. You should wear sunglasses before going outside.

4. Take a cup of water. Dissolve 2-3 granules of alum in it. Use as an eyewash.

5. Slit an aloe leaf lengthwise and place the pulpy side on the sore eye.

There are normally two main kinds of cold disinfection suggested by eye doctors:

• Chemical or multipurpose solutions
• Hydrogen peroxide systems

Checking soft contact lens care

All soft lens users need to be disinfecting lenses on taking away, as approved by their eye doctor. Peroxide structures require one, two or three unlike solutions for good and total disinfection. Chemical or multipurpose disinfecting solutions differ, in that some are a good mixture disinfecting and cleaning solutions, secure to inspire straight in the eye, and others are merely for disinfection and should be rinsed from the lens previous to insertion. Rinsing solutions are first and foremost germ-free saline solutions or salt water and are just that, for cleaning only, not during the night lens storage.

Surfactant and Enzyme Cleaners

The rinsing of soft contact lenses could be consummate with a surfactant cleaner with particular enzymes to stop working the grubby build-up on the lens surface. Some enzymes are as well liquid, as others are supplied in tablet shape and are melted in the disinfecting solution once a week. You as well might prefer to use a rewetting solution as you wear your lenses. These solutions act as a oil to increase soothe levels during lens wear.

One of the most suitable methods of soft lens care for two-week to one-month and longer substitute schedules is to use a mixture disinfecting / rinsing solution, which also has some of the crackdown properties. If you do not clean your soft contact lenses correctly every day grime and deposits could build up which could annoy and even harm your eyes. Your eye doctor would offer the best instructions for lens upholding, proper replacement schedules and the favored method for lens insertion and removal.

Soft contact lenses were originally designed to be worn for 12 to 18 months and removed nightly. These contact lenses are now called “conventional soft contact lenses”. They are usually prescribed as a specialty lens and are generally used when frequent replacement or disposable contact lenses are not available. They have the disadvantage of being more expensive and tend to accumulate surface deposits. This mode of lens wear requires more diligence with cleaning and care.

Disposable contact lenses were first released commercially in the 1980s. The first disposable lens was the Johnson and Johnson Acuvue contact lens, which was a 2 week disposable contact lens. It was a soft hydrogel lens and was primarily worn on a daily basis. The original Acuvue contact lens has only recently been discontinued. It was designed to be replaced after 2 weeks of daily wear.

Soft disposable silicon hydrogel contact lenses were first available in the 1990s. The first silicon hydrogel lenses offered were the B&L PureVision and Ciba Focus night & Day lens. Both these lenses are approved for one month extended wear. Silicon hydrogel contact lenses have the advantage of greater oxygen permeability than the original hydrogel contact lenses. Approximately 98% of patients are able to wear this type of contact lens. There is however, a slightly increased chance of developing microbial keratitis or corneal ulcer with this mode of wear. Some studies place the risk at one in five hundred per wearing year.

The next generation of silicon hydrogel soft disposable contact lenses saw the release of Ciba Optix O2 and Johnson and Johnson Acuvue Oasys. These lenses have an improved surface treatment, which leads to improved hydration and increased comfort.

More recently daily disposable soft hydrogel contact lenses have become increasingly popular. These lenses, such as J&J 1-day Acuvue Moist and CibaVision Focus Dailies have the advantage of being more hydrophilic and retaining moisture during the day.

Focus Dailies contact lenses contain AquaRelease to improve hydration and are replaced daily, leading to increased comfort from a cleaner lens. Daily replacement lenses also have the advantage of lower complication rates due to the lenses developing less surface deposits and lower infection rates. Obviously a contact lens case is superfluous with this mode of lens wear. Contact lens cases have been found to be a major source of microbes that can cause eye infections.

Contact lenses are now also available to buy online, meaning a faster, cheaper and more convenient alternative in purchasing your lenses. Contact lens wearers should still maintain a responsible attitude to lens wear, and have their eyes checked regularly by their eyecare practitioner. They should also check their own eyes daily for eye infections, by following the “Look OK, See OK, Feel OK” regime. Each morning after inserting the lenses they should check each eye look white, then check the vision in each eye separately, and then blink once or twice and ensure there is no discomfort. If there is any change, they should remove the lenses immediately and consult their eye care practitioner.

Leonardo da Vinci is frequently credited with introducing the general principle of hard contact lens. He described a method of directly altering corneal power by submerging the eye in a bowl of water. Leonardo, however, did not suggest his idea be used for correcting vision as he was primarily concerned with learning about the mechanisms of accommodation of the eye.

Soft contact lenses were first commercially available in the late 1960s. They were quickly prescribed more often than the original hard contact lenses, due to their increased comfort and shorter adaptation time. The original soft contact lenses were designed to be removed nightly and lasted 12 to 24 months.

The 1980s saw the introduction of the next generation of contact lenses - soft disposable hydrogel contact lenses. By adhering to a regular replacement regime, these lenses had the advantage of lower complication rates due to the lenses developing less surface deposits and lower infection rates.

The late 1990s saw silicon-hydrogel soft contact lenses launched. Silicon-hydrogel lenses such as PureVision and Focus night & Day contact lenses have the advantage of increased oxygen permeability, enabling them to be worn on an extended wear or overnight basis. They also result in a whiter, healthier eye.

In the 2000s a new range of silicon-hydrogel disposable contact lenses were released. These lenses such as Acuvue Oasys and O2 Optix have a hydrophilic coating resulting in a lens that wets better on the eye, leading to increased comfort and greater hydration.

Contact lenses are now available with many wearing schedules, ranging from one day or daily disposable contact lens, to monthly disposable and conventional contact lens.

There's much debate on the year glasses were invented but by most accounts, they were in use in China in the 12th century. Wide use of reading glasses weren't reported in Europe until the late 13th century. Ben Franklin invented bifocal lenses in 1784 to prevent him from having to switch glasses. George Airy invented astigmatism glasses in 1827.

Diopters are the unit of measurement used for the power of a lens. Over the counter reading glasses are usually in the +1 to +3 diopter range. The diopter range for those with nearsightedness (myopia) will always be in the negative range. Prescription lenses are those that are prescribed to an individual by an ophthalmologist or optometrist. They're designed to conform to a specific level of myopia or hyperopia.

The only problem with off the shelf reading glasses is that both lenses are made exactly the same and don’t take into account each individual’s needs. Most people don’t have the same exact impairment in each eye so the need to upgrade to a fitted pair from an optometrist may be needed.

Computer eyewear is another form of glasses taking the market by storm. With over 88 million people using a computer regularly for work or school, this type of vision correction is a burgeoning market. Computer glasses help to cut down on monitor glare as well as help prevent strain on they eyes since you read at a different distance and size than normal printed material.

Find out more on reading glasses at Wikipedia, the AC Lens vision care center, or contact your optometrist.

Eat carrots – Your mother’s been telling you for years that if you eat carrots, it’ll increase your eyesight. This is absolutely true, but it isn’t just carrots you can eat, it’s anything with Vitamin A. Vitamin A helps to safeguard against cataracts and macular degeneration. It also helps you to see better at night.

Take a break – If you spend hours staring at a computer monitor or even a television every day, then taking a break will definitely help reduce eye strain. Try to spend no more than one hour without taking a break. Computer use results in a decrease of blinking to almost one third of normal, putting even more strain than usual on your eyes.

Use good lighting – Using table lamps are better for your eyes than overhead lights. Avoid working in rooms that are dark or too dim. If you're staring at a TV or monitor, make sure the light in the room is about equal to the brightness of the display. Movie theaters make up for this by having such a huge screen that their own light fills up the room.

Get lots of rest – Eyes need to sleep just like any other organ in your body. If you’re eyes are hurting or are bloodshot, you might need to get more sleep. At the very least, you can simply lay down and “rest your eyes” for a while.

Use reading glasses – Even if you already wear prescription contacts, using reading glasses can help reduce eye strain. Not only will you be able to see small text more clearly, but you’ll also be able to sit further away from your computer monitor because reading glasses magnify. Even if you don't wear glasses at all, give reading glasses a try.

Do eye exercises – Close your eyes tightly for 5 seconds and then open them. Repeat 5 or 6 times. This will temporarily relieve strain and pressure. Lightly pressing a warm washcloth to your eyes once in a while is also a good idea. Don't ever rub your eyes too hard, though, or you may break blood vessels.

Blackle – Viewing a dark screen is better than a bright, white screen. If you tend to use Google to search, try using Blackle instead.

ClearType – If you’re using Windows, try enabling ClearType font smoothing. This will help make reading on your monitor much easier and put a little less strain on your eyes.

EyeCare Reminder – If you have to stare at a screen for a long time, taking a break is one thing, but you should also look away from the monitor once about each ten minutes. There’s even software to remind you.

Such as, disposable contact lenses, contactlenzen for extended wear, contact lenses for flexible wear and gas permeable contact lenses. Another type is also available which is for special eye care needs.
Here’s a list of helpful info for the first time contact lens wearer.
Disposable lenses: disposable contact lenses are made for those people who don’t have time to do the daily cleaning of the lenses. Some disposable lenses are meant to be changed daily while some others need weekly or monthly dispose. Annually disposable contactlenzen are also available. The annual contact lenses are made of a material which is soft and allows oxygen into the eyes.
Gas permeable or Rigid gas permeable or Oxygen permeable contact lenses: These kinds of lenses provide much clearer vision, allowing more oxygen into the eye. GP or RGP lenses are much easy to clean and last for a longer time than their other counterparts. But, these lenses are not easily adaptable. It takes time.
Extended or flexible wear contact lenses: extended wear contactlenzen can be worn for 30 days at a stretch. Aimed at people who are always on the go, these lenses don’t need everyday cleaning. You can even sleep wearing a flexible contact lens. Made of soft, flexible plastic, this kind of contact lenses are extremely comfortable and lets more oxygen to get into the eye.
Toric lenses: This kind of a contact lens is specially designed to cure an eye problem called ‘Astigmatism’. They come in two varieties namely, soft and gas permeable. The level of comfort and clarity of vision for toric lenses are same as other types of contactlenzen.
Wearing a contact lens:
First, you should always wash and dry your hands properly before touching the contact. Then put the lens on your fingertips (cup side up) and pour the liquid on it. Watch the lens closely for any kind of foreign particle. Then hold up your upper eyelid with a finger and pull your lower eyelid with another one. Look up and place the lens on the white portion of your eye. Then release your lower eyelid so that it goes up. Then look down at the floor and close your eyes for a minute. If you are getting a blurred vision, apply a few drops of the fluid onto your lenses.
Removing a contact lens:
First bend over and place your palm under the eye as if to catch something. Look down and move your finger upward and downward to take out the lens from your eye. Then clean with the solution to disinfect the lens. Always repeat all the steps for wearing and removing a contactlenzen because if you skip a step, you might end up having an infection in the eye.

Here is a Great Way to Get Rid of Them. http://www.articletrader.com/health/vision/cant-stand-glasses-here-is-a-great-way-to-get-rid-of-them.html http://www.articletrader.com/health/vision/cant-stand-glasses-here-is-a-great-way-to-get-rid-of-them.html Tue, 30 Jan 2007 00:00:00 -0600
People with certain vision conditions such as astigmatism, nearsightedness, and farsightedness can be candidates for LASIK eye surgery. During the surgery, the outermost part of the eye which is called the cornea is changed. As a result, the candidate is no longer dependent on wearing glasses or contact lenses.

Most candidates do not report any problems after the surgery. In fact, the number of less than 1% has any side effects. The surgery is on an outpatient basis. Most people return to work the next day. Their usual activities also resume the day after surgery. Side effects can happen with any type of surgery.
After the surgery, the number one complaint for candidates is chronic dry eyes. The reason for this is the surgery decreases the lubrication amount for a candidate’s eye. The severity of dry eyes can vary from serious to very serious. Some candidates after the surgery report itching, redness and maybe pain.
These problems can be solved by using artificial eye drops such as the "Refresh" brand. Another product that a candidate can use at nighttime is called "Refresh PM eye ointment". This ointment should be used at night since the thickness can temporarily cause slight blurred vision. Some people find that taking flax seed oil caplets or using a humidifier in their house can relieve the dry, scratchy feeling in their eyes. For most patients, the dry eyes and scratchy eyes usually return to normal in a few weeks or a few months. A tiny plug can be inserted into the tear ducts in the eye for the more serious dry eye problems to keep moisture from evaporating. The plug is not permanent and can be removed when the dry eye problem gets better.

It is a wise decision to carefully select your eye doctor. Be certain the eye doctor has the proper credentials and research to see the amount of successful laser vision corrections surgeries he or she performed. There are a lot of eye centers that have low prices and sound too good to be true. It probably is too good to be true. Remember, you get what you pay for. Ask around at relatives, coworkers, and friends to find the best eye doctor. To get a well established, experienced eye doctor, it will cost. But remember, this is your eye sight we are talking about. Have an experienced doctor makes a big difference. A consultation should always be done before any surgery is performed. The consultation will determine if you are a candidate to have the laser vision correction surgery. Only the doctor can determine this after performing an eye examination. The doctor will advise you if it is worth it for you to have the surgery, i.e., if your eye sight will improve enough to warrant the surgery.

Any experienced ophthalmologist will help you deal with any issues you may have after the surgery. They can recommend suggestions and put a plug in your eye if you experience serious dry eyes. Your eyes should always be checked after the surgery is performed and the day after the surgery is done. After that, you should have routine eye exams for up to a year after the sure is performed. After a year, the doctor should release you from their care as your eyes have fully healed. The eye exams for up to a year should be included in the cost of the surgery.

YEARS IN DEVELOPMENT

The concept of lenses made from silicone hydrogel was first proposed over 20 years ago. The potential benefits were clear but the technological challenge was as difficult as needing to combine oil and water to produce an optically clear product. Researcher organizations have to date invested considerable academic and financial resources to achieve the high performance soft lenses of today. They have done this quite simply because they see this material as the way forward and the ultimate standard of the future.

At the time of writing, silicone hydrogel lenses are available in the USA from four manufacturers: "Night & Day" and "O2OPTIX" from CIBA Vision, "Pure Vision" from Bausch & Lomb, and "Acuvue OASYS" and "Advance" from J&J Vision Care.

OXYGEN TRANSPORT

So what’s so special about silicone hydrogel as a lens material? Essentially, the great benefit of this material is it’s ability to transport oxygen to the eye and thus maintain proper eye health. Modern contact lens technology is all to do with oxygen permability, which is measured using the "Dk" index. And for optimal oxygen transmission, this must be as high as possible.

The Dk of traditional, non-silicone based hydrogel lenses is directly related to the amount of water that the material can hold, since oxygen dissolves into the water-component of the material and thus diffuses through the lens. The Dk in fact increases logarithmically with increasing water content. Water itself has a Dk of only 80, thus placing a ceiling on the Dk of convential materials, and the original soft contact lens material, polyHEMA, possesses a Dk of only around 10 (with a water content of about 38%).

However, in silicone hydrogels, the relationship between Dk and water content is the opposite. Here higher water content implies lower Dk. With these lenses Dk increases significantly as the silicone content - not water content - of the lens increases. The Dk values of silicone hydrogel contact lenses are much higher than those of older soft lens materials.

SLEEPING IN CONTACT LENSES

According to market data from CIBA Vision, 84% of soft contact lens wearers occasionally sleep with their lenses in, and one-third admit to doing this regularly. 25% of wearers of one to two-week disposable lenses with low oxygen transmissibility occasionally or routinely sleep in their lenses overnight. And 72% of soft contact lens wearers said they would prefer to be allowed to wear their lenses overnight provided it was safe.

Thus the demand for lenses with the capablities of silicone hydrogels is evidently very high with almost three-quarters of soft lens wearers wanting to be able to sleep in their lenses.

LENS HANDLING

Silicone hydrogel lenses are significantly more rigid than their conventional counterparts, due to the presence of silicone. This increased rigidity does possess some advantages, making the lenses markedly easier to handle and thus the ideal choice for wearers with a less delicate touch. There is a downside to this however in that the rigidity makes the lenses less prone to adopting the shape of the eye so readily, resulting in the possibility for some of reduced comfort.

REDUCED DEPOSITIONS

Historically, the deposition of proteins and lipids has been a problem with contact lenses. The amount of depositions is essentially linked to the duration of wear, the lens material and the tear composition of each individual wearer. With traditional lenses, a frequent replacement schedule greatly reduces the buildup of harmful deposits.

Silicone hydrogel contact lenses have been proven to offer major benefits in the reduction of protein and lysozyme deposition. Indeed, combined with the correct replacement schedule and appropriate care system, problems associated with protein deposition have become almost a thing of the past.

DRY EYES

A problem frequently encountered by wearers of traditional soft contact lenses is one of a feeling of discomfort and "grittiness" in the eyes towards the end of the day. It has been reported that after one week wearing silicone hydrogel lenses, the quantity of regular soft lens wearers in a particular study group who previously suffered significantly from end-of-day dryness, was reduced dramatically to only 13% of the sample.

LIFESTYLE BENEFITS

Silicone hydrogel contact lenses also provide some benefits that conventional lenses don't. Continuous wear contact lenses can be particularly beneficial for use by members of certain professions, such as medical workers, police, the armed forces and firefighters who frequently work unpredictable and long hours.

Furthermore, an increasing numbers of contact lens wearers can now enjoy active outdoor lifestyles, enjoying pursuits such as camping and hiking where it is often difficult to handle and disinfect the lenses with the appropriate level of hygiene.

THE FUTURE FOR CONTACT LENSES

There is much evidence to suggest that, owing to their significant benefits over conventional soft lenses, silicone hydrogel lenses will ultimately, and sooner rather than later, displace other types of contact lens as the prefferred choice for both daily and overnight wear for the majority of contact lens wearers. Silicone hydrogel lenses provide a much improved physical performance, excellent handling properties and greater comfort. They might be considered as the ideal lens for general purpose use that exists today and are likely to become the new everyday standard.
