While thousands seek the procedure to correct their vision, motivations behind the correction can vary significantly. For instance, countless people seek laser eye surgery simply because it makes everyday life easier. Many people tire of having to search for their glasses first thing in the morning when they open their eyes. Correcting their vision through surgery, however, enables them to see clearly, no matter what time of day. Family life is also often made easier, with parents able to attend to children quickly at night, and never having to worry about children breaking their glasses.

Comfort is another issue when it comes to seeking laser eye surgery. Many contact lens wearers, for example, suffer from dry eyes – particularly in air-conditioned areas – while those who wear glasses often feel their eyes tire out by the end of the day. Contacts and glasses also need to be cleaned on a regular basis, while glasses can easily become fogged in certain environments. Finally, many contact lens wearers can experience infections and abrasions if they’re not careful with how they wear their lenses. Laser eye surgery can tend to all of these circumstances by eliminating the need to wear contacts or glasses altogether.

Another major reason that people seek laser eye surgery is because it enables them to partake in activities that are harder to enjoy with glasses or contacts – for example, swimming, diving, rugby, or tennis. With corrected vision, patients don’t have to worry about their glasses breaking, or their contacts falling out – they can simply enjoy their favourite activities with perfect eyesight.

Finally, one of the biggest motivations behind seeking laser eye surgery is that it enhances self-confidence. Many people feel that not having to wear glasses improves their appearance, which can subsequently boost their confidence and help their performance at work and in personal relationships.

If you’re seeking laser eye surgery, it’s important to find a surgeon who fits your optical needs. It’s also essential that you never decide on a laser eye surgeon or clinic based purely on the cost of eye laser treatment. Paying that extra bit of money could mean you get a higher quality procedure, so it’s vital that you do your research, seek referrals and reviews, and meet with potential surgeons to discuss your laser eye surgery needs.

The other main category is prescription eyeglasses used for vision correction. They can either be convex or concave. The former type is capable of correcting hyperopia and the latter type is for myopia. These two types of non-plain eyeglass lenses help the nearsighted or farsighted eyes focus light entering the eyes properly. Even if there are popular contact lenses and eye surgical treatments, prescription eyeglasses have remained as an indispensable solution for many individuals. Using prescription eyeglass lenses is actually the simplest method. Compared with plain lenses, convex or concave eyeglass lenses are more complex and expensive.

Within the prescription lenses, there are still sub-categories, including single vision lenses and multifocal lenses. Suggested by the name, single vision eyeglasses are able to deal with only one vision problem. Regular prescription eyeglasses fall into this category. Until now, single vision spectacles have been the major role in the market. Individuals with nearsightedness or farsightedness are main participants of those single vision glasses. In addition, there are still multifocal eyeglass lenses, containing bifocals, trifocals and progressive ones. These eyeglass lenses are mainly for folks with presbyopia, who are still suffered by nearsightedness. It is easy to understand that multifocal eyeglass lenses can resolve more than one vision problem at the same time.

In fact, there are still many other aspects of eyeglass lenses, in addition to lens power or powers. Lenses for fashion can be applied with different colors. For extra lens feature or property, there are available various coatings. From a basic viewing point, eyeglass lenses can be made from glass or plastics.

Diagnosing the Need for Surgical Reversal of Presbyopia
Since Presbyopia is an age-related disease, it is nothing to get alarmed about. Try and see if you have all the symptoms and visit an ophthalmologist to decide the best method for surgical reversal of Presbyopia. You might need to go for presbyopia treatments if you:
* can’t read small print
* need to keep the material farther away to read it
* suffer eyestrain in reading
* can’t easily see the contrasts between small bits of texts
* ed increased light while doing reading or other works needing close look at objects

Types of Presbyopia Treatments
There are many Presbyopia treatments through which surgical reversal can be achieved. These include:
* Glasses: The use of corrective eye glasses, particularly progressive or bifocal lenses while reading is a common method of vision correction in this case. Single vision or focus glasses are usually prescribed just for the purpose of reading. These glasses will not help you see things across the room the way bifocals can.
* Contact Lenses: Some people prefer wearing contact lenses instead of corrective eye glasses due to their convenience. Interestingly, more and more people are opting for a ‘monovison’ setup where in one lens has correction for near sight while the other has correction for far sight. With both eyes open, vision is generally clear.
* Surgical Treatment: This is a permanent solution for presbyopia. These days, laser techniques such as Lasik are also used  for surgical reversal of presbyopia.

Method of Surgical Reversal of Presbyopia
Lasik is the most common of all presbyopia treatments. In this method an incision is made and a flap is created in the cornea with the help of a surgical blade. Then laser is applied to remove the targeted tissue of the cornea to reshape it. The whole process takes just a few minutes and is quite painless.  

If you are worried about your failing eyesight, you can consult the eye specialists at the Laser Eye Center of Silicon Valley. The center has the most modern equipment and one of the best treatment success rates in the state of California.

Laser Eye Center of Silicon Valley performs surgical reversal of presbyopia treatments that include laser presbyopia reversal, anterior cilliary sclerotomy and refractive lens exchange.

What is astigmatism? Astigmatism is a kind of vision disorders (usually blurred vision) caused by distortions in the curved shape of the front surface of the eye (cornea) and/or the curvature of the lens inside the eye. It can also be caused by years of stress and strain on the eyes. The strain on the eyes can weaken the tiny muscles around the eyes. Problems appear when the eyes need to change shape of cornea or lens. An irregular shape of cornea or lens prevents light from focusing properly on the retina, the light sensitive surface at the back of the eye. As a result, vision becomes blurred at any distance.

Astigmatism usually comes together with other vision problems like nearsightedness (myopia) and farsightedness (hyperopia). All of these vision conditions are called refractive errors because they influence how the eyes bend or “refract” light. Now the question is how we can do the astigmatism correction when we have these errors. Below are just a few tips which you can do to heal astigmatism.

You can use a pendulum for astigmatism correction. You just lie on the floor and swing the pendulum over your head. Try to follow and focus on direction where the pendulum moves. This exercise can keep your eyes focused on one object. If you keep doing this exercise, your eyes will have better capability in focusing on a certain object.

When you feel your eyes are tired, you should take a break. Spend a few minutes to relax your eyes. During the break you can have eye exercise by moving your eyes around. You can also look at the yard or green grass outside. Keep your eyes away from your computer monitor if you work with a computer. Relaxation can release the tense of tiny muscles on your eyes. After the relaxation you will recover your vision.

Another treatment for astigmatism is called Orthokeratology (ortho-k). This treatment uses a series of specially designed rigid contact lenses to slowly reshape the curvature of the cornea. What is good about this treatment is that it is painless.

Eye surgery is also another option for treating astigmatism. The surgery usually uses laser. The purpose of the surgery is to reshape the cornea by removing a small part of eye tissue.

When it comes to glasses offering visual correction, it is always necessary to change the glasses on yearly basis. The reason is that most people suffered impaired vision will be further bothered by visual deterioration. This phenomenon is well founded because the human eyes will inevitably affected by natural aging. While some people get poor eyesight at an early age, most of the others will be bothered by similar problems more or less in a middle or even old age. Presbyopia is such an example which nearly affects every individual over 40 years old. Once caught by poor vision, it will become necessary to receive regular eye exams in order to check whether the eyesight has been further damaged. In most cases, youngsters are encouraged to have such kind of eye exams every one or two years. They are quite likely to replace their old prescriptions and eyeglasses with new ones. Without enough information about eyeglass prices, replacement of prescription eyeglasses can give rise to much expense. So, there is a common need for most eyewear users to choose cheap eyeglasses.

The situation is similar even it comes to spectacles used for cosmetic reasons. In fact, there are a lot of designer eyeglass brands, such as Ray-Ban, John Lennon, and Wiley X and so on. Compared with regular ones, these designer eyeglasses usually charge higher prices. In an extreme case, the price of a designer pair can be several times of that of an ordinary pair. Everyone should been given an opportunity to enjoy those fashionable accessories including eyeglasses. The only way for individuals with low or medium salary to gain the same pleasure from wearing stylish designer glasses is to search for cheap eyeglasses. Taking good care, there are various ways to achieve such a goal.

In general, eyeglass users can buy a pair of prescription eyeglasses only when he or she has gained a valid prescription of the eyes. Such kind of eyeglass prescriptions can be determined by an eye doctor, either an optometrist or an ophthalmologist. An eye optician only has the right to provide eyeglasses according to a prescription given by an eye doctor. This is a strict requirement which is aimed to ensure eye safety for those wearers. In a serious case, an improper or out-of-date prescription may impair the wearer’s eyes. Prescription eyeglasses will help the eyes refocus the entering eyes appropriately, which is called “correction” in brief. But a basis point is that such kind of correction can be precise only when the eyeglass lenses have the right power according to the wearer’s eye condition. In a traditional way, most people trust eye doctors or practitioners when they want to buy prescription eyeglasses due to security concerns. In fact, other sources especially online eyewear stores can also provide safe prescription glasses. They can offer spectacles with vision correction exactly according to the prescriptions submitted by customers.

Dissimilar to prescription eyeglasses, non-prescription spectacles are designed to meet the needs for fashion. Many ordinary individuals and celebrities choose to wear designer sunglasses in summer days. Modern types of non-prescription eyeglasses usually incorporate the cut-edge fashionable tastes. Semi-frame and frameless eyeglasses are both stylish. In addition to special frame styles, non-prescription eyeglasses can also take use of unusual colored lenses. In some cases, those slightly tinted lenses can create an attractive effect. In a word, stylish elements are the key contributor to non-prescription glasses.

Characterized by an irregular curvature of the cornea, astigmatism can be detected by regular eye examinations and successfully treated using procedures such as laser in-situ keratomileusis (LASIK), photorefractive keratectomy (PRK), laser epithelial keratomileusis (LASEK), laser thermokeratoplasy (LTK) and astigmatic keratotomy (AK; Table 1). An ophthalmologist can determine which type of procedure will work best for each patient.

Worldwide, >17 million people have undergone laser refractive surgery, and refractive surgery is one of the most commonly performed operations in the United States and by Beverly Hills LASIK surgeons. The newest laser-assisted procedures are approved by the U.S. Food and Drug Administration to treat up to 6 diopters (D) of astigmatism correction, which includes roughly 98% of all astigmatism patients. Advances in laser technology continue to improve treatment outcomes.

Guttman reported on a recent study by Barraquer, a private practitioner in Colombia, of 364 astigmatic myopic patients treated with a new generation “flying spot” excimer laser. Barraquer reported postoperative best-corrected visual acuity of 20/20 or better in 99% of treated eyes at 3 months. Astigmatic correction was achieved to within ±0.50 D in 92% of eyes.

Remember that for patients in or around Beverly Hills LASIK was used after the detection of astigmatism to treat it in its early and advanced stages. Because children may also have astigmatism, it is important that eye examinations be scheduled at regular intervals to detect any astigmatism early on.

Refractive Error

Nearsightedness (myopia), farsightedness (hyperopia), and astigmatism are all forms of refractive error. Your cornea bends, or refracts, light to focus on the retina. When your cornea is misshapen the light does not focus properly. Refractive surgery reshapes your cornea, correcting how the light is bent and therefore correcting the focus of the light on the retina.

Types of Laser Vision Correction

You have probably heard of LASIK, but might not be aware that there are two types of LASIK, traditional and custom, and that there are several other forms of laser vision correction including:

• Epi-LASIK
• iLASIK
• LASEK
• InterLase
• PRK

All are performed using an excimer laser. The technique is different for each type of laser surgery, making laser vision correction possible for people who are not good candidates for LASIK.

The Precision of Today’s Laser Vision Correction

Refractive surgery is not new, but it is being constantly improved. Traditional LASIK has been used to safely and effectively correct vision for over twenty years. Custom LASIK is far more precise, and can give you even clearer vision.

In custom LASIK, Wavefront technology is used to map your eyes and guide the laser. Wavefront is also used to guide other types of laser vision correction. Wavefront diagnosis helps your ophthalmologist determine which type of laser surgery is right for you, and can detect high order aberrations that can be made worse by LASIK surgery.

Improving Your Vision and Your Life

Laser vision correction can mean freedom from corrective lenses for many patients. Those with very poor vision can achieve better corrected vision. Improving your eyesight can open up opportunities that you never had before. It may simply make things like swimming and other hobbies easier and more fun. For some, it can make essential activities, such as driving, possible. Getting rid of your glasses or contacts means waking up each morning with clear vision and never again having to worry about losing or damaging your lenses.

Myopia and Your Cornea

Your cornea bends light as it enters your eye. A properly shaped cornea focuses that light on the retina. If you are nearsighted your cornea is either too curved or your eye is too long, causing the light to focus in front of the retina. When the light reaches your retina it has started to spread out again and the image is blurry.

Eyeglasses for nearsightedness have concave lenses. This spreads out the light before it reaches the cornea, so it travels farther back in the eye before it is focused.

Laser vision correction reshapes the cornea so it can focus the light properly on the retina.

What Causes Myopia?

Nearsightedness is the most common of all vision problems and affects about 30% of Americans. In the last few decades it has become more common throughout the world. The causes of myopia are uncertain, and the subject has become quite controversial.

Heredity seems to play a large role. Children of myopic parents are more likely to be nearsighted.

Lifestyle may contribute to myopia, as well. Long periods of close work, such as reading, looking at the computer screen, and possibly even watching television, may affect how a child’s eyeball develops as they grow.

It is also believed that a diet high in simple carbohydrates increases your chance of developing myopia, due to too much insulin circulating in the bloodstream (hyperinsulinemia). Hyperinsulinemia is also common in people with type II diabetes and insulin resistance. Late developing myopia is sometimes an early warning sign of diabetes risk and can eventually develop into cataracts.

Complications of Myopia

For most people myopia is an inconvenience, but relatively harmless and easily corrected with glasses or contact lenses. If corrective lenses are too much of a hassle, laser eye surgery is an option as well.

However, myopia can lead to more serious eye conditions, vision loss, and even blindness. People with myopia have an increased likelihood of developing glaucoma and retinal detachment.

Correcting Myopia

Typically, your eye doctor will prescribe glasses and/or contact lenses to correct your vision. Eye exercises can help improve your vision, especially when eye strain from close tasks such as long hours of computer use is a factor.

Laser vision correction can allow you to see clearly 24/7, without the hassle of wearing glasses or contacts.

When ‘laser-assisted in situ keratomileusis’ (LASIK) was developed initially, the laser treatment was primarily intended for those with a specific medial condition, rather than for those simply seeking to avoid the hassles of wearing glasses or contact lenses. Furthermore, in scenarios where the treatment was available to the wider public, the cost precluded most people from venturing down the laser treatment route.

In recent years, however, laser eye surgery has come down significantly in price and is far more widely available than it once was. Furthermore, it isn’t restricted to those with medical conditions – anyone who simply wants to return to perfect 20:20 vision can be considered for it, assuming they are approved for treatment during the consultation period, of course.

In a nutshell, laser eye surgery succeeds by reshaping the cornea in the eye. By changing its form, the path of light through the eye to the retina is altered too, thus replicating the effect that glasses and contact lenses have on the eyes.

The success rate or surgery is good too, with the vast majority of patients enjoying greatly improved vision after treatment. Not everyone will be restored to 20:20 vision – indeed, some people may still have to wear glasses or contacts on occasion. The degree to which surgery helps a person’s vision will depend on the extent of their existing impairment, whilst age is a contributing factor too.

Furthermore, the laser correction process is more or less painless. There may be a slight irritation for a short period in some cases, but laser eye treatment on the whole won’t cause too many problems.

The great thing about laser eye surgery is that its benefits are noticeable more or less instantaneously. So the journey from squinting at the television to enjoying crystal-clear vision on the widescreen plasma can be as little as 24 hours.

Anyone who says that wearing glasses or contact lenses isn’t that much of a hassle may have a good point, but they probably have 20:20 vision themselves.

Indeed, life through a pair of manmade lenses isn’t difficult to adapt to, but there are many little annoyances that go with the territory that makes laser eye treatment all the more appealing. No more smudging, no more messing around with contact lens solution and, importantly, no more squinting at the television when you accidentally leave your glasses on the bus!
