For example, you better opt for your lens with a valid contact lens prescription, and it is because no other than an eye care professional can understand your eye condition and prescribe accordingly.

The right choice of lenses depends on several factors concerning your refractive error, the toleration power of your eyes, your dependence on the lenses and frequency of use. More information will the discussion provide you about how to pick suitable contacts for you.

First you have to decide how often you are to wear your contacts. Most people, who wants contacts for full-time use, wear soft contact lenses. On the other hand, if you choose to wear it on a daily basis, you would have gone for rigid gas permeable contacts. Masses wearing RGP contacts, may feel some sort of irritation, but after befitted into your eyes properly, it can give sharper vision. If you need contact lens to wear overnight, you can take one some lenses that allow an adequate amount of oxygen to pass through the cornea.

Your Cornea and Astigmatism

Astigmatism is a type of refractive error. Your cornea bends, or refracts, light as it enters your eye to focus it on the retina. In order to properly focus the light, your eye needs to be spherical in shape. With astigmatism, the cornea is oblong or oval shaped, more like a football. When the irregularly shaped cornea bends the light it creates two or more focal points, rather than one clear focal point, causing the image to be blurry.

Recognizing Astigmatism

Astigmatism can occur alone or in combination with nearsightedness (myopia) or farsightedness (hyperopia). Symptoms include:

• Distortions in vision making it difficult to make out fine details up close, far away, and in between
• Blurred vision
• Eye strain
• Headaches

Children can be born with astigmatism, or the condition can be caused by trauma to the eye due to an injury or surgery. Keratoconus is a disease of the eye that causes progressive thinning of the cornea and can cause astigmatism.

If you are experiencing the symptoms of astigmatism or any change in your vision, it is important to see your ophthalmologist right away. These can be symptoms of a more serious eye condition or health problem.

Astigmatism in One Eye

When vision is different between your two eyes, your brain chooses the better of the two images, ignoring the bad eye. The eyes do not work together properly and depth perception is affected.

In young children, whose brains are still developing, astigmatism in just one eye can cause lazy eye (amblyopia). Left untreated amblyopia can cause permanent vision loss in the affected eye.

Correcting Astigmatism

Eyeglasses or contact lenses are typically prescribed for people with astigmatism. In the past, soft contact lenses were not an option for astigmatism. Today there are soft contacts available for astigmatism, but they are more difficult to make and cost more than other soft lenses.

Corrective lenses improve your vision while you wear them, but they do not truly correct the astigmatism. Refractive surgery, such as LASIK or PRK, reshapes your cornea correcting the refractive error. If you are also nearsighted or farsighted, the surgery can correct that at the same time, giving you clear vision without the need for glasses or contacts.

The advantages of contact lenses count for the popularity of them. People tend to wear contact lenses when they are having sports or having fun. Contact lenses bring freedom for eyes. One can does his business without any restriction. In addition, the things are seen more like the real ones through the contact lenses. What’s more, many girls choose contact lenses in order to make their eyes look bigger and sharper.

Despite of those truths, contact lenses are not suitable for everyone. The people with diseases in cornea can not wear contact lenses. Teenagers are advised not to wear contact lenses because of their incomplete developed eyes. The olds are not fit for contact lenses concerning the health of eyes. In addiction, soft contact lenses are somewhat foreign objects to eyes. They may be uncomfortable for some people. In order to keep healthy, people need to clear lenses regularly. People who can not stick on the clear keep habit are not the ideal users of soft lenses. Overuse of lenses can also lead to eyes’ tiredness. People in the environment of dusts and polluted air can not wear contact lenses either.

One should think carefully before he chooses contact lenses, and receive a careful check from Ophthalmology clinic. And even for ones who are fit to soft lenses, they can’t wear contact lenses all the time or the entire place. Health of eyes is more important than one’s appearance.

There are a various number of different contact lenses. Such contact lenses can engross daily wear contacts lenses, and extended wear contact lenses and regular contact lenses — the life span of a contact lens depends on the kind and brand name of the contact lens. Specialists say that on a standard ratio, the lifespan of normal soft contact lenses is around 12 to 16 months. The regular lifespan of RGP contact lenses is around 3-4 years all depends on the handling and caring of the contact lenses. Mostly normal extended wear contact lenses must be changed after one month.

Daily wear rimless should be taken off nightly. Whilst the extended wear contact lenses could be used during the night for a week in continuation without removing them, the lifespan of the contact lenses will additionally depend on how good you take care and handle them. A healthy and good pair of contact lenses should not result in any pain to the user. If the contact lenses you are using are painful and the uneasiness does not make up or help up after clean-up and sanitization, maybe it is the right time to change the contact lenses. Cleaning up the contact lenses engrosses using a non rub or rub cleaners and sopping them wet in disinfectants overnight. There are also special proteins replacing products available in the market to take out the protein build up due to the tears on the lens. Make certain that your hands are cleaned thoroughly with soap and water before cleaning your contact lenses. For how long the soft colored contact lenses will last depends not only on the fact that how one handles and takes care of them, but also on the thickness of the contact lens.

Even though if you take proper care of lenses properly on a regular or every day basis, there comes a time when the contact lenses will turn out to be over used and may result in causing eye problems. Problems may comprise eye infection, corneal ulceration, increased mucus, sensitivity of the eyes and eyelids, and redness of the conjunctiva, eye pain, abrasions of the cornea, and sensitivity to light, blurred vision and cloudy atmosphere. Diverse contact lenses brand names and kinds are determined to last for various durations of time. Some contact lenses are intended to be used for 24 hours in a day for a full month. Some other contact lenses are intended to last for only 2 weeks.

Additionally, there are some kinds of contact lenses, which are made to last for duration of one year with proper cleaning up, and sterilization practices. If you are not still comfortable with your contact lenses by cleaning and disinfecting, and if even changing to a new pair of contact lenses does not rectify your problem, you should go and consult your eye specialist. You might have a medical eye problem or the specific kind of contact lenses you’re using may not be right for you.

Such problems as swelling of the eyes and vision haziness that are associated with the cornea, off and on result from the use of contact lens. Lenses barricade the flow of oxygen to the corneas resulting in a condition called hypoxia. Users can suffer scrapes and scratches from lenses to their corneas. Bacterial Keratitis is a corneal infection that can result from the all time use of both soft and hard contact lenses.

Persons using lenses most of the time may suffer from inflammation of the eyelids. In some cases, inflammatory bumps appear under the eyelids. They are small but painful. Persons affected with eyelid inflammation have a painful experience of wearing contact lenses.

Developing dry eyes is one of the most common side effects that contact lens is known to have. Lenses absorb a little of fluid from the surface of the eyes and as a result, leave them dry. Users of both soft and hard contact lenses are similarly prone to having dry eyes. Severe symptoms like itching or burning sensation, redness, excessive tearing and swelling surface in case of persons with dry eyes.

People who wear lenses may also experience a kind of allergic reaction. Turning of the eyes red when lenses are inserted is a common allergic reaction. Such an allergic reaction subjects the eyes to hypersensitivity that results from the preservative used in contact lens solutions. Solutions with a different preservative are prescribed for persons with allergic reaction from lenses.

The most common complications seen were papillae and giant papillary conjunctivitis.  These can typically be treated and do not generally threaten vision. They typically cause infection, mucoid discharge, irritation, and blurred vision. Papillae and giant papillary conjunctivitis can lead to lens intolerance, forcing a return to glasses for best lens corrected vision.

Comparing Risks of LASIK and Contact Lenses

Although about half of contact lens users experience complications, contact lenses still compare favorably with LASIK and other forms of refractive surgery in terms of preserving your vision. Studies show that less than 1% of people receiving LASIK surgery experience a loss in best corrected vision.  However, the likelihood of a loss of vision related to contact lens use is still significantly less.

At one time, contact lens use was associated with a potential for vision loss as high as 0.9%, but improvement in contact lens technology and wearing habits has reduced that risk significantly.  Post-market studies required of all 30-day contact lenses approved by the FDA show that the approximate annual risk of vision-threatening microbial keratitis associated with contact lens use is 4 per 10,000 wearers, or 0.04%. If we assume a 14-year life for refractive surgeries, that amounts to a cumulative risk of about 0.6%. However, rates of infection are increased 4 times for people who wear contacts overnight, and up to 15 times for people who wear their contacts for more than two weeks.

LASIK complication rates resulting in vision loss used to be as high as 5%, but recently they have been reduced to about 1%, which is close to the rates for contact lenses. For most people, the comparable safety rate of LASIK seems better when compared to the vigilance necessary to keep contacts clean with daily, weekly, or biweekly removal and cleaning.

Safety Trends

However, in the near future, LASIK may be safer than contact lenses. LASIK has improved significantly in safety since its introduction. Advanced technology and experienced surgeons are largely responsible for the decrease in complications. As surgeons continue to gain experience and technology continues to advance, we can expect rates to continue dropping. Contact lenses, on the other hand, may be more risky in the future.

Microbial keratitis used to be caused by a relatively small number of microorganisms that were controllable with specific formulae of antibiotics.  However, in recent years there have been more outbreaks associated with Acanthamoeba and fungal species. Some of this has been associated with specific contact lens solutions.  Other times, it has been associated with the reduction of water quality standards by the EPA under the Bush administration. In the latter outbreak in Chicago during June to November of 2005, 40 people contracted Acanthamoeba keratitis, nearly seven times the historical rate of this type of infection.

In the future we may see more of what are described as “atypical” cases of microbial keratitis that may increase the risk of wearing contact lenses.

In my first section,as an eye care specialist advice you to use spectacles.They are very safe and low risk. It is only possible to break glasses. And with a good eye examinatin and a suitable spectacle selection, you can confidence that you have safe eyes. You will wear spectacle in the morning and remove at bed time. Isn’t it?

As a contact lens practitioner, I recommend you high quality contact lenses If you are hated from spectacles. With a precise eye examination for contact lens prescription, you will have a good vision and more comfortable use than spectacles.There are different types of contact lenses such as spherical(for nearsightedness and far sightedness) and toric(for astigmatism) . You can use soft and hard  ones. Soft contact lenses are  more comfortable  and  easy to use. You will not foreign body sensation with them. You can use them for sports(football and …),But you should remove them before swimming and bed.

Hard contact lenses have an excelent vision,but  not durable.You’ll have some foriegn body  sensation at the first days or weeks. You can’t use them for sports. Hard contact lenses can correct for Keratoconus, Irregular astigmatism and  …

Lasik is the final solution for those hate spectacles and contact lenses. Those who have thin corneas, keratoconus,  high astigmatism and  progressive nearsightedness cases are not good case for lasik. After lasik you will have some complications such as Dry Eye, Hallos in night vision, regression of myopia , hasty presbyopia and etc.

There are many different kinds of contact lenses obtainable on the market: soft contact lenses, gas infiltrated lenses, rigid gas infiltrated lenses, contact lenses in different colors, contacts with dual lens or contact lenses with many lens and etc..

Your eye specialist may turn to the many alternatives with you, however, if you prepare yourself by learning about them prior to using them, you may prepare yourself with related questions to ask at your check up. Your eye care specialist shall turn to various perspective of proper care and sterilizing of your contact lenses, some of which is discussed concisedly under.

Proper Maintenance and Sterilizing.
even what kind of contact lenses you and your eye care specialist analize are suitable for you, proper care and sterilizing of your lenses is vital to maintaining good eye condition. Maintenance and cleaning of one’s lenses shall vary only little depending on if you has been advised prolonged use, daily use or contact lens which can be discarded after use.

You shall need some stosks ready to precisely clean and care for one’s new contacts. The necessary stocks consist: – High quality contact lens mixture – Contact lens case (facts on how to sterilize one’s cases are under) – Soft (gentle) plastic tweezers
Sterilizing one’s contact lenses is not hard, however, it is important to be very detailed and very consistent. To clean one’s contact lenses correctly, simply do the procedures under:

1.Wash and sponge one’s hands carefully prior starting the process.
2.Get each lens from the case and wash with multi-purpose mixture by ejecting the mixture onto both sides of the lens.
3.Pour one’s lens case with new mixture, put the lenses in the case, and screw the case closed. Allow the contact lenses soak for about 6 hours (overnight is most appropriate).
4.Before you place again one’s contact lenses, wash each side with new mixture again.

Sadly, simply being industrious about cleaning one’s contact lenses daily is not adequate. So that to prevent infection and better eye’s health is maintained, it is imperative} that you carefully sterilize one’s contact lens cases on a regular schedule.

Sterilizing Your Contact Lens Holders
Sadly, contact lens cases may be a source of bacteria maturity and may conveniently lead to a disease. In order to problems will be avoided arising from micro organisms and bacteria transferring to one’s lenses from one’s lens cases, you must carefully disinfect one’s contact lenses on a regular basis.

There are several different suggested methods for correctly sterilizin contact lens cases.
1.Empty, clean and rinse one’s contact lens cases every some days. The cases must be cleaned with the chemical mixtures advised by the supplier of the lens case. If no such recommendation may be found on the box, test reaching the supplier’s customer care division to see what to suggest. While this method is pretty easy, it is not guarantee in sterilizing and destroying all microorganisms.
2.Many contact lens users suggest simply placing contact lens cases in the dishpan. The heat and thorough action from the dishpan’s mechanism is practically guaranteed to destroy any microorganism on one’s contact lenses.
3.A simpler method to sterilize youone’s contact lenses with burning sensation is to put one’s contact lens cases in a pot of boiling water in one’s kitchen for 5 to 10 minutes.

At all times, be clear that you is not only sterilizing the cases, and the caps too. Be precise and regular in one’s contact lens case sterilizing. If you don’t rely on oneself to do so, simply invest in some inexpensive cases and replace them often.
