The Eyes Have It. They Are More Complex Than Any Computer In The World

The eye is made up of so many parts. Like a camera, what we see from the outside is only a simple picture to what lies beneath. The overall function and design of the eye is much more than just a white ping-pong sized ball with a colourful space and a little black dot. Your eye is the window to the world. It takes thousands of ‘calculations’ so to speak. What you see is only a small part of the overall picture. The following is a summary of each part and its function.

Check out our site for Vision Care

Part Description Function

Eye socket Hollow space/opening Holds and Supports the function of the eyeball itself

Eyelid Skin over eyeball This skin through muscular automatic and voluntarily movements. It acts in this capacity to help keep the eyeball moist and to keep it clean and free from debris.

Eyelashes Tiny hairs framing at the end of the eyelid. The lashes although decorative are there for much more than holding mascara. Lashes work to catch dirt and minimized it’s entrance to the eyeball.

Eyeball Ping-pong sized white part of the eye. The white part of the eye is made up of a tough material called sclera. It covers a huge part of the outer covering for the eye. The eye has noticeable tiny pink threads, (Blood Vessels) which deliver blood to the sclera.

Cornea Clear/Transparent dome. This dome sits in front of the coloured part of the eye. It help the eye focus as light passes through.

The Iris The Coloured Part. Controls how much light goes through the pupil

The Pupil The Little Black Dot Set in the center of the eye, the pupil is actually an opening into the inner parts, the size of this black dot is dependent on the amount of lights it’s exposed to.
When the dot is smaller, it’s due to brighter light, thereby minimizing the amount of light that enters. When it’s larger, this is due to a darker area, in opening, it allows more light in, so you can see a little better in the dark.

Anterior Chamber Not visible. The space between the cornea and the iris. The transparent fluid is there to nourish they eye.

Retina Not visible. Processes what the eye sees. It receives the signals or information which is sent to the brain for understanding.
Your retina is at the far back part of the eye that takes the light the eye receives and changes it into nerve signals so the brain can understand what the eye is seeing.
It uses cells called rods and cones to process light. In all there are about 120 million rods and 7 million cones per eye.

Lens Not visible. Like a camera, the lens processes and captures the image. It is held by fibers which are attached to muscles called ciliary muscles. It actually changes the size and shape of the lens.

Vitreous Body Not visible. This sits behind the lens, and forms two thirds of the eye’s volume and gives the eye its shape. It’s filled with a clear, jelly-like material called the vitreous humor.
Rods Not visible Works the processing of black, white, and shades of gray.

Cones Not visible. Work to process colour. They only see colours. They are most sensitive to one of three colours; red, green, or blue. Together they are able to differ what they see to form millions of other colours. Those without functioning cones experience colour blindness.

Optic Nerve Not visible. Acts as the messenger in the back part of your eye. It carries the information it sees to the brain for understanding.

Lachrymal Glands Tears. These glands produce tears for flushing foreign bodies from the eyes. This fluid is regulated by blinking.
Your eyes do so much; protect them and SEE how great they really are!!

Eye care Treatments and Conditions

You should never neglect to get an eye examination each year. Simple tests can determine if you have suffered vision changes or there is the presence of certain eye diseases. Eye care is very important. Without your eyesight you could be subject to life changing events. Your quality of life will definitely change as your vision deteriorates. As the body ages so too do the eyes, and as you get older and the risk of developing glaucoma and cataracts increases. That is why it is essential to have your eyes checked once a year.

During eye care exams, you can expect a barrage of tests. The doctor will measure how accurately you can see with both eyes open and then he or she will measure to see how far or close you can see with each individual eye. Eye doctors will also peer into your eyes with a bright, magnified light called a slit lamp. It is used to view the cornea, iris and the optic nerve.

If there is a problem with the optic nerve being too large or irregular in size, then your doctor may wish to test for glaucoma. Should it turn out to be glaucoma, there is glaucoma treatment, such as operating on the eye itself to correct the problem. The doctor may decide to give you a field vision test to determine how advanced the glaucoma is and they will measure the pressure in the eye.

The vision field test is simple. You will be asked to stare into a machine and focus on one specific black area. It is important to keep your focus on this area. Then bright lights will flash in your peripheral vision. Each time you see the lights you will press a button that registers your response. This eye care test is very simple but can determine if optic nerve damage is present.

For vision care to be received you are either going to have to pay for it yourself, which can be costly, or you can have your vision insurance company pay for the treatments and the visits. It is important to have your eyes checked, so if you do not have insurance, then you may still want to invest your money in optical examinations. Getting the appropriate care for your eyes is very important and it should not be overlooked.

A visit to your ophthalmologist for an eye care check up should definitely be a yearly event. In the case of glaucoma patients or those with hereditary glaucoma, your doctor may request that you come in every six months to monitor the presence of this eye disease. Do not neglect your eyes and schedule a regular, yearly eye examination. You will be glad you did.

Have you had your eye care checkup this year? It is important to visit a vision specialist at least once a year to ensure that your vision is healthy and that you are wearing the right prescription for your needs. You may have to go to a local vision care specialist but that does not mean that it stops there. If you want to wear contacts then you need to do your shopping elsewhere. You will find discounts not available from your local eye care specialist. To see more: “Click Here

Eye Diseases That Can Be Spotted With Annual Check ups

Unfortunately, this is a world where faulty vision and eye diseases are discovered each day. It would be great if everyone never had any problems with their eyes but the world just does not work that way. An eye care professional is absolutely essential in helping you to maintain healthy eyes. A trip to an eye care center should be part of your yearly schedule, in order to detect if your vision has changed or if there is any sign of a problem.

Eye diseases can forever change your way of life. It is far more than just having an astigmatism, myopia or hyperopia. Certain diseases can end your eyesight for good. Most slowly creep up on a person until their vision is so distorted they can no longer see correctly. A simple eye examination can uncover whether or not you have an eye disease and the eye doctor can give you options on how soon it can be treated.

There are a variety of diseases that affect the eye. These range from ocular herpes to macular degeneration. Ocular herpes occurs when the herpes virus makes its way to the surface of the eye. This condition could lead to clouded and scarred lenses or severe eye discomfort. It is generally treated by oral and topical, antiviral medications. Macular degeneration is another disease that affects eyesight. It is where the center of the eye thins, suffers atrophy or bleeding. This disease is treated with injections.

Eye examinations may also show whether or not you have glaucoma, cataracts, retinal detachment or diabetic retinopathy. If you have glaucoma, then the pressure of the inner eye increases and can lead to blindness. The only way to correct this problem is through surgery to eliminate the pressure. Cataracts develop when the lens becomes cloudy and you can no longer distinguish shapes from backgrounds. It can lead to blindness as well. The treatment for this disease involves an eye care professional removing the clouded lens and replacing it with a plastic lens.

Retinal detachment and diabetic retinopathy are diseases discovered through an in-depth eye examination. Retinal detachment occurs when the retina has detached from the rest of the eye. This condition is corrected by making a bridge so that the retina can heal. Diabetic retinopathy occurs when blood vessels are present in large numbers on the surface of the eye. Treatment by an eye care professional involves shrinking the blood vessels to help improve vision.

It is absolutely essential to seek out eye care services when you notice a problem with your vision. It may turn out to be that you need corrective lenses or it could potentially be eye diseases that can mean an end to your vision and your way of life. An eye examination is the only way to observe if there are problems.

Eye care is relatively simple. You make yearly check-up visits with your vision care specialist and you purchase the recommended eye glasses or more likely, contact lenses. However, are you aware that you can buy contact lenses online far cheaper than offered to you by your eye care specialist?

Sometimes we forget the importance of our eyes.  We have two eyes; imagine if we would lose the use one eye?  That would be devastating for us. It would be very scary to know that if something happened to the remaining eye we would be blind.
The eye is tested using an eye chart, mostly, the Snellen Eye Chart. This will show whether you have normal vision, or if you are far sighted or near sighted.

There can be many problems and diseases that occur with the eyes.  Some are not dangerous, and others can be very dangerous for our vision.  Many people suffer from eye floaters for instance, but, they pose no threat.  Eye twitching can be cause by many different reasons, some you need not worry about, others you do need to worry about. Night blindness is another vision condition.

I suggest you get in the habit of participating in your own eye care.  Be active in the health of your vision. Spend 10 to 20 minutes a day on your eyes alone.  It’s worth it, isn’t it?  And, if you want help, there is an online vision system you can use.  Check it out here, at Rebuild Your Vision.

Eye tests are important at regular intervals.  And make sure you go to a professional.  There are online eye tests available, but you will be better off at a professional eye doctor.  Get the right “eye facts” for your own eye safety.

And, make sure you do see an ophthalmologist on a regular basis.  Many diseases not related to the eyes can actually be spotted through the eyes. There are many eye care products available; From curing dry eyes to natural eye vitamins.

This article is not written for diagnosing or for treatment advice. It’s purpose is to inform you of the many different aspects concerning your eyes.  Always see a professional concerning anything to do with your eyesight.

Natural Vision Therapy

Message

People often think of their eyes as a separate part of their body.  Eyes are often “just there” and people do not ever think of actually becoming pro-active in the care of their eyes.

Just as we exercise parts of our bodies, and just as we try to feed our bodies healthy food and even specific supplements, so we must do for our eyes.  There are natural eye vitamins that are made specifically for your eyes.

Now, it is true, that you cannot fix all your eye problems / diseases, the same as you can not work off all of your other body problems and diseases.  But, you work with what you CAN help.

Contacts are a great invention for the right person.  Your eye health status may preclude the wearing of contacts. Then you are stuck with wearing glasses.  And, if you are only wearing them to improve your sight, then natural vision therapy may be another option for you.

If you are living in a stressful situation, then your eyes will reflect this.  Eyes can be very sensitive to stress. Eye stress can cause many vision problems.

If you find that your reading glasses are starting to get stronger and stronger, go to the eye doctor.  You may be in the early stages of macular degeneration!

There are ways to improve your eyesight.  Natural vision therapy includes alternative health care for your eyes.  Natural vitamin is one alternative. Natural remedies have proven themselves in many ways. Holistic health in partnership with professional doctors is a strong combination.

And remember, that you should always check with a professional.  This article is not meant for diagnosis or treatment.  Simply to enlighten you to other natural and holistic alternatives.

Laser eye surgery may not always  be what you need, or want.  Check out all your options before you commit to this treatment.

Eye infections can be very serious, so do not fool around if you think you have this condition.  Go to the eye doctor right away.

Eye exercises are a great way to help improve your vision.  And, they can help in managing stress.  Becoming pro-active in your eye care is very important.

Most eye exams use the snellen eye chart to test your vision.

Pros and Cons for Lasik with IntraLase

Pros and Cons for Lasik with IntraLase

Those who have had a Lasik eye surgery technique done, and those who are investigating having a Lasik vision correction procedure, know that the first step of that procedure is to create a small flap in order for the Lasik physician to reshape the cornea.  This flap is created by the surgeon, and can be done using a small blade or using a laser.  Using the laser is generally called a bladeless Lasik procedure, or IntraLasik, or IntraLase.

For those that are considering a Lasik procedure, this review should be helpful in order to determine the pros and cons of the Lasik procedure using IntraLase.  One comment to be made is that the risks and complications possible using the small blade are well known and documented, since that procedure has been done for years and has a database of millions of patients.

Granted, 90% or more of all Lasik patients have no serious side effects or even minor lasting side effects, but it is true that a large part of the complications from Lasik procedures stem from the flap made with the microkeratome blade.  Over the years additional techniques have been developed to further minimize such problems from the standard Lasik procedure.

The introduction of the laser to create the flap is a new frontier in the Lasik procedure.  The laser is used in combination with state of the art software to create a flap of a pre-programmed size at a specific depth and position.  During this process, a soft suction ring holds the eye in place, but this causes no discomfort to the Lasik client.  Generally the only effect noticed by most Lasik patients is a dimming of vision in the eye being worked on for the duration of the treatment of that eye.

The use of the laser creates very small bubbles of water and carbon dioxide that serve as a good buffer between the flap and the cornea itself, and so this Lasik procedure conserves the eye very carefully.  The whole process of creating a flap for one eye takes approximately one minute.

The advantages of using a laser to make the flap for the Lasik vision correction procedure is that there is no way that the cornea can be abraded, nor any chance of the wrong size or depth of flap, since it is all pre-programmed with Lasik software.  The exact vertical edges of the flap produced using this Lasik procedure help healing, and also decrease the possibility that the flap might slip or wrinkle if the eye is accidentally bumped or rubbed during the healing process.

There are very few cons to using a laser to create the flap during a Lasik procedure.  One is that the process takes a bit longer, up to a minute.  A second reason is that the low level suction during this phase of the Lasik operation does result in eye redness for about 5% of the patients, but this goes away within a few days.  The last reason is that there is still a difference in cost between intralase eye surgery and the traditional Lasik eye surgery, but hopefully that will decrease as the years progress.

Questions about Lasik eye surgery

Questions about Lasik eye surgery

Many people that wear glasses or contact lenses have listened to the claims of how Lasik can give them perfect vision.  They have also heard great Lasik success stories, as well as stories from people that were not sure they had given the decision enough thought.  This guide lists the most common questions asked by people who are considering Lasik vision correction, and answers given by reputable physicians.

The first and most important question asked about Lasik is, not surprisingly, “Is Lasik safe?”  The answer is that it is normally quite a safe procedure, with success rates above 95 percent for good, experienced Lasik surgeons, and 90 percent average over all physicians that perform the Lasik procedure.  This statistic about Lasik success assumes that the patient is a good candidate for Lasik surgery.  The requirements have some specific details and should be gone over with the physician that will perform the Lasik procedure.

It is a very good idea to ask the Lasik physician which patients he has declined to perform the Lasik procedure on, to make sure that the particular physician has and operates with good standards.  Any Lasik practitioner that tries to imply that everyone that comes in to his office is a good candidate for Lasik vision correction should be viewed with some skepticism.  In any case, it is wise to interview several different physicians that perform the Lasik procedure before deciding on one.

A second frequently asked question about Lasik is “What are the possible complications from Lasik surgery?”  Common side effects are starbursts or halos when looking at a light, sensitivity to light and difficulty with glare and night vision, and some sensation that a foreign body is in the eye.  Most of these effects will pass within a few days after the Lasik procedure.  Between 1 and 3 percent of patients will have a lasting side effect such as halos or some vision fluctuation.

It is a very good idea to discuss your particular situation with the Lasik physician to determine if you might be prone to any complications.  There are also variants of the standard Lasik procedure, one of which uses additional waveforms to map out an individual eye, or techniques that only use lasers rather than a scalpel and a laser.

One question we all hesitate to ask is “Will the Lasik procedure be painful?”  Since our eyes are one of the most sensitive parts of our bodies, it is comforting to know that having Lasik vision correction is usually nearly painless.  There is often some mild discomfort after the procedure, but this is effectively controlled with medication.

“Will I have 20/20 vision once the Lasik correction is done?”  Though many patients do get nearly perfect vision, not all patients have their vision totally corrected.  You can definitely expect to have improved vision and minimized dependency on any glasses or contacts.

“What is the cost and how do I pay?”  A typical Lasik eye surgeon charges between $500 and $2500 per eye, depending on the patient and the surgeon.  However, a Lasik physician should be selected on experience level and track record, not on the lowest price.  Insurance rarely covers the cost of Lasik, but many Lasik centers have a type of financing program offered to their clients.

Consider Lasik eye surgery as one way to significantly improve the quality of your life.

Lasik Eye Surgery or ICL?

Lasik Eye Surgery or ICL?

A number of people who are considering the Lasik procedure to correct their nearsightedness or farsightedness have of some potential problems of Lasik, and are wondering if there are other options.  Though more than 95 percent of the Lasik patients have a very successful procedure without any major side effects, there are choices for people who wish to improve their vision.  Let’s compare two, and discuss these choices with a reputable ophthalmologist.

Traditional Lasik surgery uses a scalpel to create a small flap in the eye, and then a laser reshapes the eye in order to focus accurately.  There are two more recent forms of Lasik, one that entirely uses a laser and does away with the scalpel.  Another variation uses a three dimension waveform for people with unusual eye shapes, and both of these are worth discussing with your ophthalmologist.

Those people with very thin corneas or other issues that make Lasik not a good candidate for their particular case can consider implantable contact lens surgery.  This is known as ICL in the eye surgeon’s lingo, and is a good alternative to Lasik to permanently correct vision.  These lenses function in exactly the same way as removable lenses, except that they remain permanently in the eye.  Like Lasik, they reshape the eye in order for it to focus accurately.  The patient will not feel the lens once the operation has been performed.

Lasik and ICL are similar in several ways.  Lasik can improve vision affected by nearsightedness and astigmatism, and ICL can improve these vision deficiencies also.  Both Lasik and ICL also have some of the same risks, one of these being that the correction is not accurate after the first operation is done.  Lasik is a much more frequently performed procedure, and less than 3 percent (according to the FDA) of these patients need to undergo additional surgery to further correct vision after the first Lasik procedure is done.

Like any operation, there is a chance of infection in either a Lasik procedure or an ICL operation.  Good post-operative care by the patient will minimize this and regular checkups at the Lasik or eye care center will nearly always clear this up without further complication.  In a small percentage of the cases, either Lasik or ICL patients may not achieve perfect vision and may need to continue to wear corrective eyewear, though usually not at the same strength as the original eyewear.

One advantage of ICL over Lasik is that ICL is a reversible procedure, where the implanted lens can be removed later if that becomes necessary.  Lasik involves the reshaping of the cornea to bring objects accurately into focus, and is permanent.  However, for a typical, healthy patient either Lasik eye surgery or ICL will generally bring about the desired improvement in vision.

Lasik eye surgery is generally a less invasive procedure, and this is reflected in the current cost of the operation.  The current price for a Lasik procedure is between $500 and $2500 per eye, depending on the type of procedure and the presiding physician.  A typical price for ICL is between $1500 and $3000 per eye.  Do some investigation into the options offered, and select the eye care procedure that is best for your personal case.

Solving a Lasik Post Op Problem

Solving a Lasik Eye Surgery Post Op Problem

I had Lasik vision correction surgery two years ago, and am quite glad I did.  I think that my Lasik story might be helpful to some that consider that they might not be a perfect Lasik client, and are concerned about side effects after the Lasik eye surgery.  I did have a significant side effect after my Lasik operation, but have weathered it well, and still recommend the operation highly.

My operation went exactly as described, with no pain or real discomfort at all.  My Lasik physician was clear, stating each step that he completed so that I would know the Lasik procedure was proceeding as expected, and more quickly than I had imagined.  I know that all of the discussion I had earlier with the Lasik professionals stated the operation generally took less than twenty minutes, but I was still surprised.  

At the end of the operation, my Lasik doctor replaced the flap to its correct position in my eye and covered it with some kind of clear goop.  Even at that time I could notice a distinct improvement in my vision.  I was instructed to wear goggles over my eyes for five nights in order to prevent me rubbing my eyes while I was sleeping.  I guess they assumed that any good Lasik patient would not do that when awake.  

In addition, I followed all post-op Lasik procedure instruction to the letter.  I slept immediately after the Lasik procedure was done (after I made it home, of course), used the eye drops religiously, and did not try to strain my eyes by reading everything that I could.  I was amazed the immediate improvement in vision that Lasik makes, just as if there was a set of weightless contact lenses.  Very impressive.

My biggest problem in Lasik eye surgery recovery was a result of epithelial erosion.  The flap that is made in the eye during the Lasik procedure is made from epithelial cells.  Once the flap is replaced at the end of the Lasik procedure, these cells start to regenerate in order to fill in the line where the flap has been cut.  All of this is normal post-op Lasik healing.  However, in my case the cells would grow fine, but at night my eyes tended to dry out when I was asleep.  So, when I woke up, my eyelid would pull up some of the new cells from their place where they belonged, where if my eye was sufficiently moist they would have stayed in place.

I told this to my Lasik eye surgeon, who said this side effect just makes healing a little longer and it was not a serious side effect.  When I went for a checkup to the Lasik center (which I highly recommend any time a Lasik client has any post-op worries or questions) they decided that I needed a thicker, more jelly like version of the eye drops to use at night.  This worked well, and the rest of my post-Lasik recovery went well.  
I am a strong advocate of the Lasik vision correction procedure.  I also strongly suggest interviewing a number of positions, and do not put low cost as the highest priority.  Your eyes are very important, and a highly competent Lasik physician is the most important factor.

The Facts About Intra Lasik Eye Surgery

The Facts About Intra Lasik Eye Surgery

Now that Lasik vision correction surgery has been accepted for a number of years, there are several popular options for the procedure.  One of these is IntraLasik, or Intralase, or bladeless Lasik.  As the name implies, there is no cutting of the eye with a blade, instead the flap in the eye is made using a laser.  Since bladeless Lasik is a newer procedure, there are a number of opinions around about how well this procedure works.  Let’s look at several of these and determine which of these are true or false.

First, more Lasik clients get 20/20 vision or better using IntraLasik.  Any Lasik procedure cannot guarantee perfect vision for every client, though more than 90% get results to at least 20/40 vision.  However, it is true that the new techniques of IntraLasik do get even better statistics for giving clients clear vision.

Some are concerned that the laser that makes the corneal flap is standard, and cannot be tailored to each individual eye like can be done by the Lasik surgeon when using a blade.  This is not true.  The Lasik physician has control over the use of the laser for each individual in the same way that he can control the microkeratome blade.

IntraLasik can be used for both a standard and a custom Lasik procedure.  This is true.  Custom Lasik procedures using Wavefront technology (another somewhat recent advance in Lasik vision correction) can easily be used with a laser making the initial flap.  This custom Lasik procedure, though more costly, is of great benefit for people with unusual eye shapes or problems.

Some have heard that using the laser is less accurate than the standard Lasik procedure.  This is not true, since lasers can be controlled to micron level accuracy.  This gives the Lasik physician extreme control to create exactly the flap needed for this particular individual eye: the precise size, shape, and depth for successful completion of the Lasik procedure.  

Another common fallacy is that IntraLase has not been around long enough for trusted Lasik physicians to have confidence in it.  On the contrary, many of the most honored Lasik physicians strongly endorse IntraLase due to the track record of very good results from the Lasik procedures.  In addition, the quality of the machines and the precision that they give these Lasik physicians is very impressive.  Many of the top flight Lasik doctors recommend this as a procedure of choice, assuming cost is not a significant variable in the decision of which Lasik procedure to use.

Similar to the objection above, some people think that Intralase is not a sufficiently test Lasik procedure option.  On the contrary, more than one million of these procedures have been performed, and the impressive track record for this Lasik procedure has been discussed above.  More and more Lasik physicians are trained in this option, and we will see many more such Lasik procedures in the future.

We hope that this discussion of bladeless Lasik has given more accurate information to those considering this Lasik technique.  Please discuss this option with the professionals at your local Lasik center.
