Has your eyesight deteriorated to the stage where you have to wear specs? Are you all right with that? Well, there are a number of alternatives to be had nowadays, so you do have other choices. If you do not want to undergo surgery, you can still opt for contact lenses. In fact, contact lenses have been a feasible alternative to glasses for decades.

Surgery can be a more permanent solution to problems with eyesight, but for various reasons, some people do not want to take up this option. This leaves contact lenses as the best alternative. The first thing to notice about contact lenses is that most people will not know that you are wearing them. This is very important to some people and not significant to others at all.

Contact lenses offer better all-round or peripheral vision than spectacles. When you look to the side wearing spectacles, there is no glass there, but contact lenses cover your entire pupil so that your vision is closer to normal. This is safer if you are driving a car or riding a bike or even trying to cross a road.

Another problem that many people find with spectacles is that they leave indentations on the nose. Some people find these unsightly. Glasses also need frequent cleaning, which many people consider annoying, whereas contact lenses are cleaned by the eyes' normal cleaning system - in other words, automatically.

Stylists also think that their prescription specs have to go with what they are wearing. This can mean that you have to have a dozen pairs of glasses. If your eyesight deteriorates further, which is fairly likely, all those spectacles will have to be up-graded as well. This is not the case with contact lenses naturally.

Both glasses and contact lenses can correct astigmatism or bad eyesight, which comes to most people after the age of forty. Sometimes earlier and sometimes later, but it will happen. Your choice, if you do not want to undergo surgery, is whether you would rather wear specs or contact lenses.

In the past, contact lenses were very expensive, which is why many people still discount using them, but in fact it is no longer true. Contact lenses are more costly, but not much more now. In fact, you can buy disposable contact lenses and many people do do that.

The fact is that there are better alternatives to wearing either contacts or specs, but most people do not know it. It is possible these days to have one eye operation and never have to wear glasses again. Or you could have laser surgery and almost certainly not need specs again for ten or twenty years, but some people are adverse to having surgery and so they opt for glasses or contacts.

In the long run, surgery is almost definitely less expensive than wearing contact lenses and wearing contact lenses is almost definitely cheaper than wearing glasses, but it is the same with most things, people merely look at the up-front costs and cheaper is hardly ever better.

Although more and more people are becoming aware that they ought to follow a low (er) cholesterol diet as they become older, they might not be aware of how to do this. People eat out a great deal more now than ever before or they have food delivered.

Unfortunately most of the food consumed at or from these places has a poor record when it comes to regulating cholesterol. You will find it difficult to impossible to follow a low cholesterol diet and eat junk food at the same time.

There are plenty of examples of low cholesterol diets on the Internet and it would be a useful thing for you to look at some of these until you find a chef's recipes that match your tastes.

For instance, one cook might have a penchant for vegetarian cooking and so would create a collection of low cholesterol recipes containing vegetarian food, while another cook might favour fish and so would create lots of low cholesterol recipes involving fish.

Obviously, if you have more varied tastes then the world is your oyster and you can mix and match recipes from all over the world. There are several cultures that do not eat meat at all, for instance, the Hindus. There are thousands of Hindu recipes which are obviously low in cholesterol or which could be easily adapted by substituting olive oil for ghee as the oil in which to cook.

Or you might like the Japanese style of cooking, which involves a higher proportion of fish than we eat in the West. Fish is a very useful source for example of HDL, or decent, cholesterol. Japanese meals can be of a number of different styles. an unusual one of which is sushi, which has become popular with the trend-setters.

Chinese and Thai food also uses far less meat that traditional Western recipes. They also tend to cook using soya oil, which is a product known to lower the level of LDL or 'bad' cholesterol. If, when you look at traditional recipes from these countries, you notice something you could improve on then go ahead and modify it.

For example, when you go to a Chinese restaurant, you always get white rice. Why not substitute brown rice? The same goes for Thai food. Brown rice is fed to convicts in Thai jails, so it is coupled with low class, hence Thais eat white rice. But you do not have to.

If you like barbecues, you may have to lay off the steaks, chops, sausages and burgers, but you can still barbecue all types of fish, crabs, prawns and lobster. Eels are good for a barbecue too and so is unleaven bread and some vegetables such as sweet corn.

There are so many examples of low cholesterol diets that eating in this way does not have to become monotonous. In fact, it might just open your eyes to some of the other ways of cooking going on in the world. You may just end up realizing that most of the meals in your life up to now have been fairly similar.

When you are searching for examples of low cholesterol diets, bear in mind that adaptation and substitution are the best tactics - be adaptable and enjoy your new, healthier diet.

The patient of Lasik surgery has two main duties regarding his or her eyes: firstly to choose a responsible, skilled surgeon, which should not be too problematic and secondly, to take care of his eyes after the surgical procedure by following the guidance of the surgeon on post-operative care. This second part is very necessary and should not be taken lightly.

The post-operative care process is not a problem, but if you are worried about it, you could enquire of your surgeon what it will entail before the operation. The doctor or a nurse will be able to explain the method of supervision to you in detail or they will give you a brochure.

There may be some peculiar sight aberrations for a couple of days after the operation, some of which are fairly normal. One of the most common aberrations that are standard for a couple of days are halos around lights.

However, you should be certain that you understand the difference between what is standard and so no grounds for concern and what should be reported immediately

There are different Lasik procedures and the procedures are advancing all the time so it is not possible to give precise details in this article. Moreover, the shape of the eyes and the causes for deteriorating eyesight are individual to each patient.

Some of the advice that your Lasik surgeon might give for your post-operative eye care may include the following, although different doctors might have their own advice.

The first thing is to remember that you have just had an operation including anaesthetic. There might not have been any blood but it was surgery all the same.

All patients are required to take it easy after an operation and you will be no exception. If you had had an operation on your knee, you would use it as little as possible for a time and the same is helpful advice for your eye.

Attempt to sleep for a few hours after the surgery or at least close your eyes and rest. Infection is the chief concern, so do not poke or rub your eye and do not strain it by trying out your newly improved eyesight by reading or watching TV.

If you have to entertain yourself in this way wear an eye patch. Your surgeon will almost certainly have given you a stiff plastic eye guard, which you should wear at all times.

Some surgeons will warn against getting water into your eye for a few days, which means washing only from the neck down, no showering, no going out in the rain and definitely no swimming.

Be careful with bright light, it cannot damage your eye but it does hurt. Your world will get much brighter after the operation and looking at a light bulb can be painful. Be careful of watching moving traffic whilst the sun is shining, a car window can catch the sun and reflect it back into your eye all of a sudden.

You will be given eye drops so do not fail to use them. Lasik surgery can dry your eyes out, if this happens they might be able to give you substitute or extra drops.

Do you know what is Diabetes mellitus? Diabetes mellitus is the condition characterized by the increased level of glucose in blood. Diabetes mellitus is a common condition, and there are several individuals around the globe, who are suffering from this illness.

Diabetes mellitus develops due to several reasons. One of the major reasons is the lack of insulin inside the body. Insulin is a hormone, which controls blood sugar level. The role of insulin is to decrease glucose inside the body and transfer it to the cells and tissues, where it can be used for energy generation. Insulin is secreted by a specific area inside the pancreas, known as islet of Langerhans.

The disease can be broadly classified into two major categories; First those individuals who develop diabetes mellitus since their childhood. These are those individuals, who develop this illness as a result of lack of insulin. This is called as type I diabetes mellitus. On the contrary, there are some other individuals, who use to develop type II diabetes mellitus. This type is developed as a result of insufficient insulin in blood. It means that those who are suffering from type II diabetes mellitus still secreting insulin unlike type I; however, their secretion is insufficient to control blood sugar appropriately.

Diabetes mellitus is considered one of the major culprits of several lethal illnesses. A person may become more prone to develop heart diseases, stroke, kidney failure and other problems in the long run. According to an estimate, more than 50% individuals suffering from terminal illnesses possess diabetes mellitus since many years.

Few years back, another variant of diabetes mellitus is discovered. This variant is called as insulin resistance. According to an estimate, around 25% individuals around the globe are suffering from insulin resistance, with or without obvious symptoms of diabetes mellitus. This is condition in which a person develops resistance to insulin. It means he does have insulin secretion in his body, but it remains in inactive form.

One of the major causes of diabetes mellitus is obesity and increased body weight. Those who use to eat more carbohydrates and sugary items are also prone to develop diabetes mellitus more frequently.

It is necessary to get instant checkup for the timely diagnosis of this condition. This is the only way to prevent some lethal illness and to protect the body from several other diseases which become more common as a result of diabetes mellitus.

You have to be very cautious with your eyes because they can so easily be damaged beyond repair. My eyesight started to deteriorate when I reached forty, like most people. My friends and family put that down to the fact that I was sitting in front of a computer screen for about twelve hours a day and had done since I was twenty-eight. Still, there was nothing I could do about that, that was my job. I was self-conscious of wearing glasses at first, but you soon become over that.

My eyes continued to get worse and at a greater rate than friends of a similar age, but I considered that that was merely the luck of the draw. However, one morning about ten years later, I woke up and it was as if my glasses were dirty. I spent the next day or two cleaning them, but I could not seem to shift the dirt on the right lens.

By that time, my eyesight was too bad to see without specs and I only had the one pair. I had moved to rural Thailand and acquiring a second pair was no easy achievement.

After a couple of days of cleaning and polishing my glasses a friend offered to take me the 75 km to the nearest good hospital. The opthamologist looked in my eyes and said: "I am very sorry, but you are senile". I had been called mad before, but not senile. I was fifty-two. It is not really a statement that beggars a question, so I just looked at him and put on a glum expression, hoping that I was not confirming his diagnosis.

He looked at me and then looked in his desk, pulled out a book and opened it. "You have premature senile cataracts" he corrected himself. I was not sure whether that was any better as it implied that other parts of me may begin failing early as well. Anyway, I thanked him and left. I had no idea what to do next, but at least I knew better that to continue wasting my time attempting to clean my already spotless glasses.

My wife is very practical and she arranged for us to go to an even better hospital 650 km away. I was seen by one of the hospital's senior eye surgeons within the hour and was told that I had a cataract in my right eye and that there was a good chance that I would develop one in the left eye too. Then she shocked me by asking: "Do you want me to remove it now?"

It was too big a decision for me to make there and then without any information, so we discussed the operation, she gave me a leaflet and I made an appointment to return the next day. The next day, I was in the operating seat. I was not going to have Laser Correction, but the full replacement of the lens. The operation is carried out under local anaestetic and does not hurt but it can be uncomfortable at times.

The surgeon cut a small opening of two millimetres a little to the outside of the colour of my eye and squirted in some liquid. She then vibrated that liquid with ultra-sound to break up the lens in my eye and flushed the pieces of lens out with more fluid before inserting the new lens through the same hole.

By this stage of my life, I could just see light and dark with my right eye, but at one point my eyesight just ceased entirely. It was like watching a window shatter before your eyes only to realise that there was nothing but blackness beyond. Now I definitely was blind in that eye. There was a bit of discomfort, but the surgeon kept talking to me and then she said: "Wait, wait, wait, can you see me?"

And I could.

Absolutely perfectly. Better than I would have been able to fifteen years before, but everything was so bright that it dazzled. I had not noticed how dingy my world had become. A cataract is like having a net curtain over a window, it cuts out a great deal of light. Therefore, the first thing you become aware of whilst you have had a cataract removed is a flood of light. Your world literally is a brighter place - to such an extent that the light hurts.

Be careful with light after the surgery, it cannot bring about lasting damage, but it really does hurt. A passing vehicle can reflect sunlight into your eye and catch you unawares. If you are driving or riding a bicycle, it could be very dangerous. Another risk is reflection. You have an open wound on your face which can get infected by wind-borne germs.

The week following the procedure is a great deal more risky than the operation itself. You have an open cut in your eye which they do not stitch. It is left to heal itself, which is not a problem, if you take precautions.

You have to put two kinds of drops in your eye four times a day and avoid getting water in your eye at all costs. That means do not go out in the rain and do not wash your hair in the shower. Dirt and consequent infection are your main enemies, so put the drops in regularly, avoid dust (and the powdered dog faeces mixed in with it) and all water and be very wary of light.

Losing one's vision can get upsetting. In the beginning, if as standard, you begin to lose your vision at around 40 years of age, it is the first sign of approaching old age, but later as it deteriorates further, individuals begin to worry whether they will go blind.

Well, if you require spectacles at 40 then yes, it is the first sign of approaching old age, but there are not so many individuals who go totally blind now due to advancements in information concerning the eyes and how to treat impairments.

There is nothing you can do regarding the former difficulty, but at least two routes you can take to sorting out the latter.

Most individuals 'blindly' follow their opticians advice and buy specs or contact lenses. This is the best option for the optician and the cheapest option for the client in the short term. It is good for the optician because you will probably need new glasses each two years and contact wearers have to keep buying contact lenses too.

It is handy for the customer because the outlay is small if you do not go for designer frames like Gucci or Levi. In the long term, though the client pays out many, many times more than if a different procedure had been chosen.

One of these alternative courses of action is Lasik surgery. This is expensive up front, but can last for 20 years although you might still need specs for either long or short distances. Most individuals have their long distance eyesight corrected and never ever have a problem with it again, although they do still require reading spectacles.

A third option, which you might like to try instead of or in conjunction with any of the above is known as Natural Vision Improvement. It has to be said that the technique of Natural Vision Improvement has more detractors than supporters, but some people regard it as a form of yoga for the eyes which cannot do any harm.

The point here though is that if you would like to try Natural Vision Improvement, you should still go to an optician regularly so that they can check for eye diseases like glaucoma and macular degeneration, which Natural Vision Improvement cannot hope to, nor does it claim to, cure.

Advocates of Natural Vision Improvement say that contemporary equipment like TV screens and monitors and even living in a city where long distance eyesight is almost unnecessary because it is blocked by buildings a few yards away, have trained us to 'see badly'.

They say that we need to relearn how to see in the correct manner. They even go as far as to say that spectacles and contact lenses may be part of the problem.

Here they mean that as your eyes become used to corrective lenses, they come to rely on them and so become weaker. Therefore, the next time your eyesight is measured, you will need more powerful glasses.

The Natural Vision Improvement philosophy says to use the weakest lenses that you can and make your eyes work harder. In this fashion, they insist, the next time you go for a check up, you can get weaker lenses not stronger ones until eventually you do not need spectacles at all.

Some opticians and optometrists will go with you if you want to attempt this route, but you might have to look about for one. One important point around the Natural Vision Improvement course of action is that if your impaired vision could create a danger to yourself and others, you must wear standard, full-strength glasses when carrying out those events (like driving).

I have never had Lasik eye surgery, although I have had both of my human lenses replaced with plastic ones. However, I wanted to help a friend retell his story of Lasik eye surgery, because I know from my own experience that there is a lot of nonsense talked about having eye surgery of any form.

I robustly urge anyone who is thinking about having cataracts removed, Lasik eye surgery or absolute lens replacement to go ahead and have it done as soon as they can. There will be no looking back, I assure you and you will live in a brighter world again that you had not noticed had been growing gradually but surely ever dimmer.

I shall name my friend Fred to make it easier for me to tell his story and that of numerous others who have been in a comparable situation to him. Fred wore specs all his life or from the time that he was in the Navy doing his national conscription service anyway.

He got used to this predicament, but was growing concerned at the rate that his glasses were growing in thickness year on year and the growing dependency he had on them.

After months of worry and chatting to 'friends' in bars, he resolved to go talk to the only other person whose opinion really mattered - the Lasik surgeon. He was fairly nervous that they would say that his eyesight was too far gone, but he was also worried that they would say he could have the operation because he had a terror of anyone doing anything to his eyes which could rob him of the little bit of eyesight that he still had.

The surgeon said that both of his eyes could benefit from surgery, one maybe a little more than the other, but that he would definitely still need spectacles for the rest of his life, albeit weaker ones than he was using now. In effect, the surgeon was stating that he could restore most of Fred's long-distance vision but that at his age, 63, he would still need reading specs.

Fred turned up on the day of the first operation having not been to the pub and having had an early night. In his circumstances they operated on one eye at a time with a week in between the operations. They started both session by putting drops in his eye. These drops dilate and relax the eye although the eyeball does not really feel any pain.

The operations lasted about three minutes each, but Fred is not sure how much of that was 'laser time'. He said there was a sensation of intense white light, but no pain whatsoever. He was required to stay in the waiting room for thirty minutes afterwards and then he went home.

On his physician's advice he had taken a friend with him, because your old glasses will not fit on top of the protective shield on your treated eye. This shield had to be worn for 24 hours to prevent Fred from poking or rubbing his eye inadvertently.

Fred had taken the next day off work, but he says there was no necessity and he did not bother the next time. Fred's eyes have improved hundreds of percent and sometimes he can even read without spectacles too.

Lasik surgery has hugely improved the sight of millions of individuals worldwide. It has turned the visually impaired into sighted individuals who are capable of seeing their children again and contributing to the family's earnings by working. Two items that millions considered they would never be able to do again.

However, Lasik eye surgery has not been sitting on its laurels. Far from it, Lasik surgery techniques are being enhanced all the time. One such improvement is Wavefront Technology. Wavefront Technology with relation to Lasik eye surgery is used to more precisely map the patient's eyeball, which makes more accurate surgery feasible.

This is of immense importance because eyeballs are not all the same shape. They are like hands, superficially they all look the same, but once you get down to detail, they are not. There are all shapes sizes and proportions. The same goes for eyes.

The better the map of the eye, the more chance that the surgeon has of giving you the best vision they can, in relation to the precise problems that you have in your particular case. Wavefront Technology assists the surgeon accomplish this.

Wavefront Technology is really a technology that has been modified from astronomy. in astronomical telescopes it is crucial that the lenses are as flawless as they can be, because at high magnification, even the very least impairment would lead to colossal distortions, which in turn would make the telescope just about useless.

Astronomers were using this technology in the 1970's, so it was already quite advanced when some bright spark noticed that it could become adapted for use in eye surgery too. Wavefront Technology was born and taken on board by Lasik and other eye surgeons with great expectations.

In fact, the bright spark who recognized the potential value of this piece of astronomical technology was a German physician named Josef Bille who began using it in his practice.

He gradually improved and adapted the sensors and announced it to the Lasik manufacturers in 1997. This in turn allowed the manufacturers of Lasik apparatus to adapt Wavefront Technology to their own apparatus.

Wavefront Technology is extremely complicated in design and technology but also highly simple to understand. The Wavefront machine sends a flat sheet of light (called a wavefront) through the eye to the retina, which reflects it back to the Wavefront machine.

The Wavefront machine compares the two, measures the imperfections, chooses what has to be done to right them and guides the laser to the right spot in order to achieve the corrections. As easy as that!

However, the geniuses who created and developed Wavefront Technology did not give up there. They have their machine send in several wavefronts from various angles so that the computer can build up a three dimensional picture for even more precision.

There are now well over 60 patterns that can be automatically corrected by a Lasik laser guided by Wavefront Technology. So, if you have any issues with long or short sightedness, create an appointment to see your Lasik surgeon as soon as they can.
