Nutrition that Supports Eye Health

Your vision is one the most precious gifts you have. Maintaining good vision and eye health throughout your lifetime is important. There are a number of proactive tips that can help you to take care of your most delicate sensory organ—your eyes.

If you are concerned about your eyes you should be mindful of the sun’s rays, working long hours staring at your computer, watching television, pollution and environment, and a poor diet—all which can affect eye health. Simple eye care health tips can help you to protect your eyes from possible damage due to environment and the stress of everyday life.

Wear sunglasses when you’re out. The UV rays of the sun can harm your eyes as well as your skin. Optometrists say you should wear sunglasses on a sunny day or a cloudy day. Clouds may partially block the sunlight, but UV rays can penetrate clouds. Even if you wear UV-protected contact lenses, you should wear sunglasses to protect the whites of your eyes.

Computer tips. Keep your monitor about five to nine inches below eye level. This position offers the least strain on the eyes and is conducive to blinking. Most people working on the computer do not blink as often as they should. Blinking helps retain moisture levels in the eyes and is good exercise for the eyes. Following the “20/20/20 rule” may also help relieve eye strain caused by too much time on the computer. Every twenty minutes look away from the computer and fix your gaze about 20 feet away for 20 seconds. This will help keep the eyes focused. Splashing cold water over your eyes during breaks can ease eye tension.

Regular exercise. Engage in a regular exercise program. Exercise helps to maintain optimal blood circulation and ensures that the eyes receive a supply of oxygenated blood.

A healthy digestive system. Eye health, as with overall health, depends on the proper absorption of nutrients.

Drink plenty of water. Drink about 8 to 12 glasses of water a day. Cloudiness in the white of the eyes may be due to insufficient water intake.

Get sufficient rest. Getting a good night’s sleep refreshes the eyes. Lack of sleep can cause the eyes to appear tired and lacking in luster. Tired eyes may not perform at optimal levels during the day.

Smoking and alcohol consumption. Smoking can have adverse affects on overall health and, particularly on eye health. Smoke irritates the eyes and eventually may effect the proper functioning of the eye. The same is true for alcohol. Too much alcohol can also diminish your body’s ability to absorb Vitamin A.

Do not rub eyes. Do not rub tired eyes, as any irritant in the eye can damage the surface of the eye. Instead, palm your eyes and massage in circulation motion.

Contact lens wearers. Most contact-lens wearers make the mistake of overusing their contacts. Contact lenses are not designed to be worn for more than twelve hours a day, as it can cause discomfort and may lead to eye damage.

Eye nutrition. Including plenty of fruits and vegetables in your diet is a good way to get the proper nutrition to support eye health. Vitamins and minerals, such as, Vitamins A, C and E, zinc, selenium, folic acid benefit overall health, but are especially beneficial to eye health.
Cabbage, carrots,, papayas, green peas, spinach and other green leafy vegetables such as lettuce, collard greens, turnips, broccoli, and kale are all rich in beta carotene and other eye nutrients. Liver, lean ground beef, egg yolks and seafood are also healthy for the eyes.
Eye nutrients you should consider incorporating in your diet include:
Bilberry:Bilberry has been used for centuries to support eye health. Its nutrients can help protect against eyestrain and fatigue. Bilberry also supports a healthy blood circulation to the eyes.
Vitamins: Vitamins A, C and E are antioxidants. Vitamin A is well-known for its role in supporting eye health. Vitamin C nutritionally helps in tissue cell regeneration and supports healthy blood vessels. All three of these vitamins can help to protect the body, including the eyes, from free radicals. Vitamin A supports the regeneration of rhodopsin—which is found in the rod cells of the human eye.
Carotenoids are powerful antioxidants, too. They also nutritionally protect cells from free radicals. Carotenoids, specifically beta-carotene, are believed to enhance the function of the immune system. Beta-carotene is the precursor of vitamin A in the body. High concentrations of certain carotenoids are found in the eyes. Eating foods which have greater amounts of these carotenoids may help maintain eye health.

For Eye Health Try to Eat Foods that Contain:

Lycopene helps to maintain optimal vision. Lycopene is found in tomatoes; processed tomatoes contain higher concentration of lycopene.
Lutein is found in the center of the retina, called the macula. Lutein is found in food sources such as spinach, broccoli, and peas. Often called, “nature’s sunglasses”, lutein protects the eyes from blue light present in sunlight, fluorescent light, welding light, and light emitted from television and computer screens.
Zeaxanthin, like lutein, is found in the macula in high concentration. Lutein and zeaxanthin are often found in combination in the same vegetables, likespinach, broccoli and peas.
Selenium is necessary for the absorption of Vitamin E. Mixed nuts, especially Brazil nuts, are rich in selenium. Fish is another good source.
Zinc is highly concentrated in the retina. It is essential for oxidation and metabolism. Zinc is also responsible for the release of Vitamin A from the liver. Zinc is found in abundance in protein-rich foods. All kinds of meat and fish contain zinc. Dairy products and pumpkin seeds also contain zinc.
Copper is needed for the assimilation of zinc. Food sources that contain copper include green leafy vegetables, whole grain cereals, organ meats and nuts.
It is important to begin the right eye health care regimen as early as you can to maintain eye health. As you age your body’s ability to absorb nutrients that are required to support eye health may change.If you are not able to maintain a balanced diet, you may want to consider eye health supplements for a consistent supply of nutrition that will promote eye healthcare. Taking a supplement like Crystal Vision Matrix to nutritionally support eye health can help to close the gaps your diet may leave. Ask your doctor whether a supplement, like Crystal Vision Matrix, is the right choice for you.

Eye Health

Good Eye Health Practices

"Even in the glasses of thine eyes, I see thy grieved heart," said Shakespeare- a very protective observation of the human eye. This incredible organ of sight not only permits us to see but is most often a barometer of our emotions and our state of health, as well. It is believed that the famed Maimonides, world renowned physician to the Sultan prescribed medicines for his patients (clients) just by looking into their eyes.

The eye is a special sensory receiver. The eyes are the greatest clues to diseases elsewhere in the body, more so than any other organ. We use our eyes for driving car, watching television, reading books and newspapers, and watching movies. The eye is a fantastic, incredible piece of engineering- an instantly self-adjusting camera, with a built-in drainage and repair system, so it requires only reasonable eye health care from its owner in order to provide good and constant lifetime service.

When reading, writing, or doing other close work, the source of light should be steady, non-glaring, and easy to read by. The light should come from behind. The entire room should be lighted, not just the working area. Indirect lighting is preferred to direct.

When doing extensive reading or writing the eyes should be rested for a minute or so from time to time by closing them or looking at faraway objects.

Sunglasses at night or in darkened places are ill-advised. Even in the daylight sunglasses should be worn in glared conditions, unless otherwise instructed by a physician. Watch television at night with lights on.

An eye that has caught cinder must not be rubbed; it should be allowed to tear and be washed out by a gentle stream of clear water. Boric acid or other eye preparations are dangerous when the eye is injured, so consult a physician before using them because self medication is not advisable.

All children should have their eye checked no later than the beginning of school, regardless of whether they have symptoms or not. Adults over 40 years of age should have a regular eye checkups.

Non-acute symptoms that must also be investigated are: aversion to reading, unusual fatigue after normal eye use, an unusual number of errors in writing, difficulties in concentrating, and headaches, particularly those that radiate to and from the eye.

Optometrist & Ophthalmologist : A Healthy Eye Is A Beautiful Eye

To ensure your eyes remain healthy and beautiful, you may need to look more closely at the value of an annual exam.

Regular eye exams are not just about obtaining optimal vision through the right eyeglass or contact prescription but can also help detect early warning signs of disease that can affect your eye health and general health.

Since an eye examination can help detect many health problems, eye care practitioners often work in conjunction with internists and general practitioners to help empower individuals on their health and wellness journey.

Many doctors offer new technology, such as digital retinal eye scans, that are quick and comfortable and produce a computerized picture of blood vessels in action. This new technology effectively provides information on eye health and certain systemic health conditions, such as diabetes and glaucoma.

With more than 50 million "prediabetics," 65 million hypertensives and 5 to 10 million Americans with high pressure in the eyes, a regular eye exam is important for your eye and overall health.

Taking the following steps, according to the experts, can help keep your eyes healthy:

1. Begin a regular routine of eye exams with an optometrist or ophthalmologist once a year or as often as the doctor recommends.

2. During the exam, talk about what the doctor is doing during the various procedures and ask for a health and wellness summary.

3. Ask the doctor how soon the next exam should be scheduled. The advice will vary depending on several factors, such as the patient's history of health and disease, age, and use of contact lenses or other corrective lenses.

4. Make sure you explore all your options. Ask your doctor about new technologies that can help you see better. For example, Advanced View Progressive (AVP) lenses are one of the latest technologies in multifocal eyeglass lenses.

5. Like other regular health exams, set up your next appointment before you leave the doctor's office and ask if they can send you a reminder.

6. Finally, remind your friends and family members. Make sure they also know about the importance of regular eye exams.

A regular eye exam is about more than getting a stylish new pair of glasses. It can help keep your eyes healthy.

What is the Difference Between an Eye Exam and a Contact Lens Exam

Whether you think you need vision correction and are considering contact lenses, or whether you’ve been using glasses or contacts for years, you may be curious about the difference between a routine eye exam and a contact lens exam. Perhaps you’ve never thought about it, always assuming that both are one and the same. The truth is, there are some fundamental differences between these two types of exams. The information below will give you an overview about each type of exam and explain the difference between the two so that you can ensure you are scheduling the right type of appointment with your eye care professional.

Routine Eye Exam
A routine eye exam exists for the purpose of detecting vision problems, eye disease and general eye health issues. An eye exam can help identify any of these concerns before you are even aware that they exist. It is generally recommended that everyone have a routine eye exam every 1 to 3 years, depending on age, risk factors and physical condition.

What to Expect
Eye doctors use a variety of tests and procedures to examine your eyes. You will most likely be asked to read an eye chart. First you will read the chart with both eyes uncovered. Then you will read the chart while you cover one eye (and then the other eye). Your eye doctor will then perform tests which may or may not include these common tests:

Retinoscopy
For this test,the lights in the room are dimmed and you will be asked to focus your eyes on a target. While you stare at the target, a light will be shined into your eye and flip different lenses in a machine in front of your eyes. The way the light bounces off of your eye will provide a general approximation of what your prescription (should you need one) will be.

Refraction
This test helps your eye care professional determine the exact level of augmentation that your vision requires. Refraction is done with a machine called a phoropter. The doctor will show you a series of lens choices and ask you which of the choices looks clearer. Based on your answers,the doctor will be able to determine your level of nearsightedness, farsightedness, astigmatism and/or presbyopia.

Slit-Lamp Examination
A slit-lamp is an instrument that allows your doctor to examine the health of your eyes using a machine that highly magnifies all the structures contained therein. This way,your eye doctor can examine each part of your eye to evaluate them for infection or disease.

There are various other tests that eye doctors can choose to use during an eye exam to determine the general health and well-being of your eyes. A contact lens exam is different in that it focuses on only one aspect of your eye health.

The Contact Lens Exam
If you wear contact lenses or are considering starting, you should make sure to schedule a contact lens exam versus a regular eye exam. Basically, your eye doctor will need to run tests that will evaluate the surface of your eye’s cornea in order to ensure a proper contact lens fit. Your doctor will also ask a series of questions about your lifestyle and preferences in order to determine the best type of contact lenses to prescribe for you. The doctor will measure the surface and curvature of your eye using an instrument called a kerameter. Then your pupil and iris will be measured. Finally, your eye doctor will select contact lenses for you and instruct you in proper insertion and care.

Latest Technology’s Best Eye Treatment- Lasik Surgery

LASIK is an acronym for laser-assisted in-situ keratomileusis which is an eye surgery. Lasik surgery is the most well-liked method for correcting visualization difficulties caused by refractive error, in which the eyes fail to focus light appropriately. Lasik surgery treats nearsightedness, farsightedness, and astigmatism, radically decreasing and often abolishing the requirement of glasses or contact lenses.

This is the following process of Lasik surgery:
Initialy, the eye is anesthetized with use of limited anesthetic drops. Once you can't sense your eye, a small flap is formed on the surface of the cornea by means of a particular instrument known as a microkeratome which allows the surgeon to access the corneal bed.

After cautious placement of the corneal flap, a cool-beam, excimer laser restructures the cornea, shifting the eye's focal point to endow with clearer vision.
The corneal flap is then softly relocated and will begin to cure instantaneously.

In conventional Lasik surgery reforms the cornea, the part of the eye that visualizes light on the retina. In Lasik surgery, that reshaping ensues after a planned eye treatment taking into account the precise refractive error of the eye. A nearsightedness disease is corrected by flattening the cornea, while farsightedness is fixed by steepening the cornea. The concluding result of lasik eye surgery is for most patients, vision good enough that they no longer need glasses or contacts for most activities.

But in customized lasik surgery, physicians apply it to patients to reduce night vision turbulences like glare and halos. A good percentage of custom Lasik surgery recipients gain twenty by twenty visions from this method, which uses modified treatment in the form of the wavefront analyzer, which permits for a higher level of diagnostic information.

Wavefront technology begins through NASA, where it was initially used for high-powered telescopes. The wavefront analyzer generates a detailed map of your visual system twenty-five times more precise than standard lasik surgery can produce. This level of fact allows for tiny irregularities known as higher order aberrations to be incarcerated and fixed. This highly customized data which is then transferred to the laser used in your Custom lasik surgery treatment, where it will best treated for your sole vision problems.

Lasik surgery can fix up the vision of the nearsighted, the farsighted, and those with astigmatism. Once you have had your lasik surgery, you will possibly want to recommence your normal activities almost instantly, but be cautious. Whilst in lasik surgery, you should still pursue this rough timeline before you jump back into your normal activities.

Laser Eye Surgery A More And More Popular Procedure

Laser eye surgery is becoming more and more popular as more research is conducted and more sophisticated procedures are being developed. Laser eye surgery is the best alternative to glasses or contact lenses, as it removes the need to don any object in order to improve upon one's sight. Laser eye surgery is now much more safer and less expensive then it was ten years ago, and no one can foresee the advances that scientists will make in the field in ten years.

Specialized doctors all across the nation are now involved in this field. The business is lucrative, as many people are interested in the procedure, as well as prestigious. The service is even being advertised heavily on TV now, and there are many establishments completely devoted to laser eye surgery.

As stated, eye care is very cheap (relatively) nowadays. Some companies who have put their businesses online proclaim they will perform the procedure for less than three hundred dollars. On television, advertisements for laser eye surgery have deals such as, "Pay $2,000 for one eye, and get the second eye half off!" Some people have even pondered about getting one eye done and then having the other done months or even years later, just to save money.

Some of the long term effects of laser eye surgery are not yet known. A humorous look at a possibly "blinding" effect is your eyes falling out after ten years (Simpsons). Of course, that is extremely unlikely, if not totally impossible, as an effect that extreme. However, it is truly unknown about some of the lesser serious long term effects laser eye surgery, but that small possibility should not stop anyone from receiving the procedure, if they need it.

It might be better to wait a few more years before having laser eye surgery, as so far the research has been exponential and it become even more safer and effective then it is now in just a few years. Still, the technology today is still amazing, and it is definitely worth having the procedure done now.
