When women and men consider their overall health, they normally do not even think about the health their eyes are in. But the eyes are counted on more intensely than just about every other part of the body system. Due to the fact that this is so, it is tremendously important that you take care of the well-being of your eyes so you can continue to depend on them to get you through the day. Of course, there are numerous ways to work at safeguarding your vision, however the one most crucial thing you have to do is get a comprehensive eye exam.

No matter who you are or what your age is, a complete eye exam will go a long way towards ensuring that your sight remains clear and robust. The eye examination can be carried out by any reputable optometrist in your area. The eye doctor is qualified to give their patients an in depth examination that incorporates various tests we will consider below. If you have not been to the optometrist in more than a year, book a consultation for an eye exam as quickly as feasible. So, let’s take a look at a number of the issues that an optometrist checks for during your examination, and what they will do to treat the problem.

Some of the initial things that an eye doctor will look for during your eye exam is refractive error. Refractive error describes an inaccuracy in the manner that the eye focuses on light. The final consequence of a refractive error is a reduction of visual acuity (i.e. acuteness or quality of sight). In the event of mild refractive error, patients sometimes decide to leave the situation uncorrected. However, if the problem infringes on the patient’s capacity to perform their every day jobs, then action has to be undertaken. At the time of your eye examination, the optometrist will establish the issue and outline the options for the patient. In many cases, refractive error will be treated by wearing eyeglasses or contacts. In more extreme circumstances, the patient will prefer to have refractive surgery. This can all be clarified more by your qualified optometrist in the course of your eye examination.

Another thing to ponder is the fact that the eye may be predisposed to certain problems, similar to other parts of the body. Most people have heard of the most familiar disorders of the eye, which include glaucoma and diabetic retinopathy. Since these ailments usually display no signs and symptoms in their early stages, it is vital that you maintain an active methodology to avoid them. This can only be accomplished by making a planned visit to have your eyes examined. The eye doctor will have the ability to look for diseases like glaucoma to ensure that you can take the suitable steps to eradicate the disease before it gets any more serious. Even though these diseases are more generally diagnosed in elderly individuals, it is vital to note that there is nonetheless a possibility for eye disease to occur at an earlier age.

There are numerous other disorders that your eye specialist will be checking for during the course of your eye examination. For example, the eye ailment called Amblyopia, or lazy eye, is typified by its subpar sight in an eye that would be typically considered to be normal. Produced by an inadequate stimulation of vision by the optic nerve to the brain, this problem can be worsened if it is not treated straight away by an eye specialist. Your eye specialist will also look for Strabismus, a further eye problem where the eyes do not effectively align. This disorder impedes the patient’s capacity to execute depth perception, and as such ought to be diagnosed by an eye doctor without delay.

Finally, it is important that the difference be made when comparing a basic vision screening and an in depth eye exam. Many people trust that by having a registered nurse or primary care doctor provide a vision screening they are sustaining a sufficient level of eye care. What they do not realize, however, is the fact that the vision screening may only include the reading of letters off a chart which vary in dimensions. After bearing in mind the different other evaluations that have been explored above, everyone will appreciate that the vision screening does not take into account the other assorted conditions and ailments that you may endure.

Therefore, by having a full eye examination on a consistent basis, you can help ensure that your eyes remain healthy.

The most well-known part of a comprehensive eye exam is the basic visionblog_photo_12_31_15 test. When you have a general vision test, one of the main conditions the eye care practitioner is checking for is a refractive error. A refractive error means there is an abnormality in the shape of the eye, changing the eye’s ability to focus light directly onto the retina.This causes blurred vision and can usually be corrected by wearing prescription eyeglasses, contact lenses and possibly, alternate treatments such as vision therapy, ortho-k, LASIK or refractive surgery such as LASIK.

The term, “refractive error” refers to a problem with the process of refraction that is responsible for sight. Normally, light rays that enter your eye are refracted or bent through the cornea and the lens, and ultimately converge or are focused onto a single point on the retina. From the retina, messages are sent through the optic nerve to the brain which then interprets these signals into the image that we are seeing.

In order for this process to work effectively, the anatomy of the eye including the length of the eye and the curvature of the cornea and the lens must be just right to be able to focus the light onto the retina. When this is not the case, a refractive error will occur.

There are several different types of refractive errors, depending on which part of the eye is affected, and it is possible to have multiple refractive errors at the same time:

Myopia or nearsightedness:
In myopia the length of the eyeball is too long which results in light coming to a focus in front of the retina, rather than on the retina. This allows the individual to see well when objects are close but not clearly when looking at objects at a distance.

Hyperopia or farsightedness:
Hyperopia is when the eyeball is shorter than normal and can result in near objects being blurry. However, people experience hyperopia differently. Sometimes distant objects are clear while other times people may experience overall blurred vision near and far or no problems at all. In children particularly, the lens may accommodate for the error allowing for clear vision but may cause fatigue and sometimes crossed eyes or strabismus. Hyperopia causes eyestrain or fatigue especially when looking at near objects for a period of time. Often people with 20/20 vision may still need glasses at their desk to relax their eyes and improve concentration.

Astigmatism is usually the result of an irregularly shaped cornea (although it can sometimes also be due to a misshapen lens). The cornea, which is normally round, is more football-shaped in an eye with astigmatism, resulting in multiple focus points either in front of the retina or behind it (or both). People with astigmatism usually have blurred or distorted vision to some degree at all distances, near and far.

Presbyopia is an age-related condition which usually begins to appear sometime after 40. As the eye begins to age, the lens stiffens and can no longer focus clearly on objects that are close.

It’s important to note that presbyopia is often confused with hyperopia, as both cause problems focusing at near distances. However, high hyperopia can also cause blur at far distances as well, especially in dim lighting, and depth perception problems can result in motor vehicle accidents. In these instances people with hyperopia could use glasses at any distance.
If you are having trouble seeing, it is important to have an eye exam to determine the cause of the problem and to effectively correct your vision. Even if your vision is fine, you should schedule a routine eye exam on a regular basis to ensure that your eyes are healthy and that any potential problems are caught early.

Sometimes a person is unable to produce enough tears or their tears do not possess the right qualities to keep eyes healthy and comfortable. This can cause a consistent lack of sufficient lubrication and moisture on the surface of the eye, known as dry eyes.

Normally, the eye constantly lubricates itself with tears by producing them at a slow and steady rate, keeping itself moist and comfortable. Usually these tears consist of three layers, an oily, a watery, and a mucus layer. Each layer has a specific role in lubricating your eyes. The oily layer is outermost. It’s main purpose is to slow evaporation of the tear. The watery layer is in the middle. This makes up the majority of what a person normally thinks of as tears. This layer cleans the eye and helps to wash away small foreign objects and particles. The inner layer consists of mucus. This mucus allows the watery layer to stick to the eye and spread evenly over the eye in order to keep it lubricated. In a person with dry eyes, either hormonal changes, side effects from medication or some other factor causes the eye to either not produce enough tears, or leave out parts of the tear that make proper lubrication possible.

Dr. Ezra Cohen, of Sunsation Eyewear in Brooklyn, New York explains, “Symptoms of dry eyes include stinging or burning in the eyes, scratchiness, and excessive irritation from smoke or wind. Although it may sound counter-intuitive, the eyes’ response to the consistent irritation caused by dry eyes may also cause a person to experience excessive tearing. In this case, the eye is attempting to flush and lubricate itself by producing more tears, but is unable to do so successfully due to the rate of evaporation or inability to spread the tears properly.”

Although dry eyes are not always curable, your optometrist may prescribe artificial tears to help with some of the symptoms. Artificial tears are lubricating eye drops that may help with dry, scratchy feeling eyes. Different artificial tears work in different ways. Some help replenish parts of the tear that your eyes are not producing on its own, others help to produce more tears overall. Your eye doctor will assist you to choose which will help you most. Dr. Cohen cautions, however, “These artificial tears should not be confused with eye drops that are advertised to ‘get the red out.’ These eye drops may indeed reduce the appearance of redness in your eyes, but this is accomplished by making the blood vessels in your eyes smaller rather than actually lubricating your eyes. As such, these drops can sometimes actually make your symptoms worse. One should also be aware that if you wear contacts, some eye drops require you to take them out before using the drops and wait 15 minutes or more before reinserting your contact lenses.”

Some cases of dry eyes are seasonal, such as those which occur as a result of cold, dry winter air. In this case, your eye doctor may recommend wearing sunglasses or goggles when outdoors to reduce your eyes’ exposure to the sun, wind and dust. For indoors, your optometrist may recommend an air cleaner and humidifier to take dust out of the air and add moisture to air which is too dry.

Studies have also shown that nutrition may have a part in helping to relieve some symptoms of dry eyes. Your eye doctor may recommend nutritional supplements such as omega-3. Good sources of omega-3 fatty acids are cold-water fish, cod, herring and salmon, as well as flaxseed oil. Mild dehydration can make symptoms worse too, so be sure to drink plenty of water, 100 percent fruit and vegetable juices and milk.
