First of all, you will need to consult your doctor. Discuss with him/her your situation and the problems you are experiencing and an analysis will be made of your situation. Remember, not everyone will be suitable for lasik eye surgery. some of the reasons you may be rejected include:

  • being under the age of 18.
  • being pregnant
  • eyes must be in a healthy condition

At a young age, peoples eyes are still in the evolving stage and any complications which may exist could improve over time. Young people are encouraged to give it a little extra time before considering lasik treatment.

With pregnancy, lasik is discouraged because of the refraction or bending of light due to hormonal changes. Surgery response may be a little skewed for pregnant woman and this also applies to women during the nursing stage.

If you have been having ongoing problems with your eyes and they are not in a healthy or stable condition then lasik may not be an option for you. Your doctor will determine this and be extremely forthright about it. Rejection in this instance is usually a precautionary measure.

Lasik eye surgery is a relatively safe and painless procedure. Lasik surgery techniques are such that the procedure is quick and is usually performed within 10-20 minutes. Local anaesthethic is used.

It involves a laser cut flap on the eye cornea and lifting it and is then followed by a laser re-shaping of the tissue underneath it. When completed the flap is then replaced. No stitching is required and the healing process begins. Protection is placed over the eye so the cornea isn’t subject to outside damage.

The healing process is usually very quick, in fact, in some cases, people have been able to resume work duties the following day however, most patients are advised to take a few days off. Side effects aren’t immediately noticeable although some mild irritation may be felt in the form of slight burning or itching. Depending on the level of discomfort, medication may be prescribed.

Lasik surgery techniques are amazingly effective and once you qualify, the decision will be yours on whether to have the surgery. The success rate is extremely high and the benefits certainly outweigh the negatives. Ultimately, it will be your decision on whether it is worth the slight risk involved.

bookmark_borderInfo of Titanium Eyeglasses

Titanium comes out of the ground. In rocks. It is popular because of a very high strength-to-weight ratio (thanks wiki!) To use an example, it might take a pound of steel to hold up king kong, but it only takes 1/2 a pound of titanium to do the same thing. While heavier than aluminum, pound-for-pound, titanium is twice as strong.

The benefits for using titanium in eyeglass frames now seems obvious. This metal will result in frames that are equally as strong as steel frames yet are only half the weight. Titanium makes a lot of sense. Don’t let any retailer tell you it will change the world, but it will provide a lighter pair of glasses equally as strong as a steel pair. Also, the other side of this is that if you know you’ll only be wearing a pair of glasses an hour or two at a time (e.g., sunglasses or fashion glasses), you might get the best bang for your buck out of cheaper steel frames.

A final note is that titanium is often alloyed, or combined, with other metals such as nickel. Some titanium frames are 100% and some are alloys. Unfortunately, the online retailers don’t seem to be disclosing this information. I will contact a few and post again in a couple of days. Generally, you want to avoid an alloyed frame if you are allergic to nickel or other metals with which titanium might be alloyed. The rationale behind the alloying process is that the manufacturing process is easier and the titanium becomes easier to manipulate.

This nice looking pair of frames is from EyeBuyDirect

The style name is “Free.” It looks like this particular pair runs about $40, plus probably $20 or so in coatings and upgrades. A whole lot better than the $400 I remember my father paying for a pair back in 1999.

Update: I stumbled upon this blogger whose father squished a pair of titanium eyeglasses. They were all mangled, but apparently they were able to be fixed without any breakage! Pretty neat metal, that titanium.

bookmark_borderProtect Your Eye From Sun

Even though lenses are the very significant feature, if the frames permit a substantial amount of light to enter the eyes without first being filtered through your lenses, much of the sun protection would be lost. The most effectual frames are wrap around style, which blocks light from coming at the sides. Wraparounds as well hug the face; decrease the value of light, which could further enter over the top or at the cheekbones.

It is further important that the lenses provide maximum sun protection. This is not reliant on how dark the lenses are, but somewhat on their capability to filter out assured wavelengths. Hunt for the lenses, which block 100% UV-A and UV-B rays. These are the similar rays, which cause sunburn and other skin cancer as well. Though UV-C rays are regularly mentioned, the earth’s atmosphere blocks almost all of these.

It is as well significant to find for lenses, which filter near-UV light. Studies put forward that extra exposure to near-UV light adds to macular erosion as we age, a chronic disease, which causes in deteriorated image clarity. Quality sunglasses would have a tag or supplementary information exposing the amount of sun protection they offer. Sunglasses missing this information most likely do not offer maximum sun protection, as 100% UV blockage and HEV filtering are important selling points.

Though sunglasses do not have to be costly, quality sunglasses are in facts an investment in the long-term health of your eyes. Sunglasses that offer good sun protection would as well assist to defend the fragile skin surrounding the eyes from early wrinkles and skin cancer. All the way around, a high-quality pair of sunglasses is an investment well worth the money. Your eyes deserve high-quality sun protection.

bookmark_borderContact Lenses Work

Contact lenses are prescribed to a wide variety of individuals who have vision problems associated with astigmatism, nearsightedness, farsightedness, and presbyopia. The retinas of individuals who suffer from these conditions cannot properly focus light. When the retina does not function properly and/or does not properly focus light then the result is imperfect and blurry vision.

Contact lenses are made differently depending on the eye condition they are trying to correct. For instance, if you suffer from astigmatism your optometrist will measure your cornea so a contact can be made precisely to fit your eye. By doing this a contact is made that will fit your eye perfectly and direct light rays to one place on the cornea, which in turn corrects your vision.

Those suffering from myopia, also known as nearsightedness, will wear lenses that are thinner in the middle and thicker on the edges. This design allows the light rays to be processed correctly by the retina.

Farsightedness sufferers are prescribed just the opposite contact lens, but with the same end result. They allow the retina to process light correctly as well, resulting in corrected vision for the wearer.

All contact lenses use the basic technology to correct vision for the wearer. They redirect light to the retina so it is processed correctly. The only difference is contacts are made differently to treat different eye problems.

An optician or ophthalmologist is not just the person who writes you a prescription for glasses in Raleigh. They are actually a health professional who is responsible for checking and ensuring the health of your eyes. They are specially trained to look for disorders such as glaucoma, macular degeneration, and other issues that can be devastating for vision and a person’s overall health.

Many times, the optician or ophthalmologist is the first person to notice that a patient has a disorder that needs to be treated by a medical doctor, since many illnesses and disorders are visible through an examination of the eye. In addition, if you already suffer from a disorder such as Bells Palsy or diabetes, an ophthalmologist can make sure that your eyes are minimally affected.

Besides these obvious reasons for the necessity of your annual eye exam, it is important to remember that your prescription for lenses in Raleigh will eventually become outdated. Eyes are constantly changing, making it very important to get new lenses in Raleigh each year. Many people experience enough vision change that their prescription is updated every year.

People with eye problems such as blurred vision, trouble focusing, eye pain, and headaches even though they are wearing corrective lenses in Raleigh, may be dealing with an outdated prescription. No one should continue to wear the same lenses for years without seeing an eye doctor to check for a change in prescription. When your prescription isn’t right, your eyes struggle to focus causing many other physical problems.

One way to make sure your vision doesn’t decrease over time is to see an optician or ophthalmologist each year. Additionally, follow his or her suggestion on getting new eyewear in Raleigh as your eye sight may diminish over time due to wearing an outdated prescription.

bookmark_borderInfo of Choosing Quality Sunglasses

You the consumer need to be more observant in your shopping, and that includes sunglasses. You need most importantly to check the label: do the sunglasses offer a UV Protection of at least 99%? And do they offer both UVA and UVB protection? If not, look elsewhere. Sunglasses are supposed to have labels with this information, so if you don’t find these valuable details listed, then avoid these sunglasses.

You also need to know about lens color. The darker lenses of sunglasses do not necessarily protect your eyes more than lighter colors. In fact, if the color is too dark, it will hinder your ability to see clearly from them. And if you drive, that could be quite dangerous. So you need to pick a lighter color, and as long as the label shows that they offer the UV protection you need, you are in good shape. But of course don’t pick sunglasses where the lens color is too light, or else you might not be protected from the sun’s glare. Gray or green are good colors to choose, for example.

If you do much shopping, you know that some sunglasses are very expensive, because of who makes them. The high profile names such as Dior and Gucci will offer higher-priced items as you know. But that doesn’t mean they aren’t designed with quality in mind. In fact, most of the luxury brands not only ensure 100% UV protection, but also are quite comfortable, sturdy, scratch-resistant, and are designed to last a long time. So don’t discount luxury-named sunglasses; often these can be of the best quality you can find.

Also, the shape of sunglasses is more important that you think. The reason is because, if the lenses are too small, the sun’s rays can sneak into the sides of your eyes. I myself have these wrap-around glasses that not only feature large lenses, but little lenses on the side. I admit they look a little weird, but when I’m driving they work great, so who cares? Then again, I don’t like these itty-bitty sunglasses; you know the kind, with
super-small lenses that offer no protection and frankly, don’t even look that great. The oversized lenses are so much better, offer maximum protection from the sun, and can be extremely fashionable and stylish.

In conclusion, when you get your sunglasses, don’t neglect to take good care of them. Keep them in a sturdy case when they’re not in use, and clean the lenses with a soft smooth cloth. That way, your sunglasses, whatever their cost, can last a long time.

If you take all the steps mentioned above, you can be assured of having yourself a fine pair of quality sunglasses. The pair you get will give ultimate protection against the harmful sun’s rays, will guard against glare, and might just last a lifetime. Oh and they will probably look good too!

bookmark_borderMacular Degeneration

Macular degeneration is a deterioration of the macula. The macula is at the center of the retina. The retina is the part of the eye that sends visual images to the brain so a person can see. This damage to the macula results in blind spots, blurry or distorted vision. This disease is one of the major visual disease in the United States.

There is not a lot known about macular degeneration. What is known, however is that it is closely linked with aging. There has also been a link found between the disease and a gene variant called complement factor H or CFH. Macular degeneration has two forms: dry or wet. Dry or non-nonvascular macular degeneration is the most common and occurs in 85% to 90% of diagnosis. Wet or nonvascular macular degeneration is a rarer form that results in the worst vision impairments. It is thought that the dry form is caused by thinning of the tissue in the macula. The wet form may be caused by leakage of blood and fluid into the retina.

Since little is known about what exactly causes macular degeneration it is hard to prevent it, but there are some guidelines that have been developed on risk factors that may contribute to the disease. The following list is of those risk factors.

  • smoking
  • age
  • gender (women are at more of a risk)
  • family history
  • high cholesterol
  • race (Caucasians are at more of a risk)
  • exposure to ultraviolet light (less is better)

These are just factors that have been studied and shown to play a part in increasing the risk of developing the disease.

bookmark_borderTransitions Lenses

Let us make clear one thing first. Transitions do not change as quickly as you see in the commercial. The time limit on most commercials is 60 seconds to get the point across. Transitions take approximately 60 to 90 seconds to get to their darkest state in the direct sun and approximately 2 to 3 minutes to return to a very light grey once you step inside a building. After an extended time indoors the lens returns to a virtually clear state. The Transitions lens is known as a variable clear lens. These lenses automatically adjust to changes in the amount of light the lens is being exposed to at any given time. So inside the car or under a tree or overhang the lens will lighten because the exposure is not as much as in the sun as much as 50% or more. The amount of lightening depends on the time of day and amount of sun exposure at the time.

Transitions lenses block 100% of the UV rays that can be damaging to your eyes and can reduce glare on a somewhat cloudy day. It is also nice that these lenses lighten inside the car which helps in being able to see things in the interior of your vehicle without removing your sunglasses. For those who prefer a dark lens inside the car, a separate pair of sunglasses may be necessary. They also have a manufacturer’s scratch protective coating on the front surface to cut down on minor scratches that can happen during normal use. The photochromic property of these lenses is also affected by temperature. Transitions work better in colder weather. If you live in a hot climate, you may notice they don’t work as well in extreme summer heat and better during the winter months.

The Transitions Lens can be an ideal choice for those not wanting to carry two pairs of glasses. They are now available in most lens materials and lens styles. Transitions lenses are an excellent choice for children in eyeglasses. Protection for UV damages to the eyes should start at an early age. What better way to acquire that and comfort from the bright sun than to include Transitions in your eyeglass lenses.

  • Wash your hands. While this might seem like common sense, it’s important to note that before you put in or remove your contact lenses you should wash your hands so that they are free of dirt, germs and debris. When you do this step, however, avoid using a moisturizing soap since this is not good for contacts. After washing, use a lint free towel to dry your hands.
  • Remove one of your lenses and clean it as recommended on the bottle of solution that you use as per your eye care practitioner’s recommendation. Cleaning per the instructions is important because this will remove the protein deposits as well as other debris that build up on your lenses and can cause discomfort as well as impair the way you see through them. Some solutions will have you rubbing the lens and others will just have you rinsing it.
  • Rinse the lens per instructions. This is important because this will wash off the loosened debris.
  • Make sure your contact lens holder is clean and fill one side with your soaking in disinfecting solution in place the lens in the case. Disinfecting your lenses for the recommended amount of time is important because this will kill the microorganisms that could be growing on the lens and will help you avoid infection.
  • Repeat for the other lens.

In addition to these steps, your doctor may recommend an enzymatic cleaner that removes proteins build up. This typically is not needed for disposable lenses, but if you have lenses that you wear for a year or more the protein buildup can make them uncomfortable in impair your vision.

At first, these clear flashes don’t last very long, but they will gradually last longer and longer. Your average daily vision will also improve along with them. When you have a clear flash, you’ll be really tempted to strain your vision to ‘hang onto it’, but this is actually self defeating. As I’ll explain in the next chapters, one of the causes of your poor vision is eye strain. Any kind of straining of your vision, will just make your vision worse! When you get a clear flash, and it begins to fade away, just say to yourself, “I did it once, I can do it again” and you will.

While this doesn’t really count as an authentic vision improvement clear flash, it is handy to know how to do it, when you need to see clearly in a hurry and you don’t have glasses handy! Its easy to spot this one, as you can feel excess moisture on your eyes. Tear film clarity is not even and usually it only occurs for a split second and is moved around by blinking.

Sometimes you just look up and “Oh my god I can see!” This is usually accompanied by a deep sense of peace, comfort, relief and relaxation in your eyes. Involuntary clear flashes can last from a few seconds to minutes or even hours. This is your natural vision, and as you progress, it will happen more and more frequently and last for longer and longer, until eventually, it just becomes your natural state. During a clear flash you will notice that black is very black. Memorize it. Also, detail is phenomenal as central fixation is taking place. There is also a strong sense of 3D, as your eyes are now working perfectly as a team.

After having many involuntary clear flashes, some people learn that by relaxing in a particular way, and playing with some of the muscles in their eyes, they can “bring on” a clear flash. Again this is very useful when you need to see in a hurry and you don’t have your glasses handy!

Hope you had an insight to your eye.
