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.
