COMPREHENSIVE EYE EXAMS
The Benefit of Regular Eye Exams
Getting an eye exam is an important part of staying healthy. A comprehensive exam not only secures that your eyes themselves are healthy, but your doctor can also look for changes noticed when there are other health problems in the body.
Comprehensive eye exams should be performed on children around the age of 4 to screen for Amblyopia (Lazy Eye), and adults should be examined at age 40. If there are no systemic diseases that suggest otherwise, adults can be examined just once every 5 years until the age of 65, at which time, they should be examined yearly due to the higher incidence of cataract, glaucoma and macular degeneration.
What is Included in a Comprehensive Exam?
A comprehensive eye exam is relatively simple and comfortable and shouldn't take more than 45 to 90 minutes. The exam should include checks on the following:
Your medical history. First, your doctor* will ask you for an assessment of your vision and your overall health. Your family's medical history, whether you wear corrective lenses or whether you are on any medication will also be of interest to your ophthalmologist.
Your visual acuity. This is the part of an eye exam people are probably most familiar with. Your ophthalmologist will ask you to read a standardized eye chart to determine how well you see at various distances. The test is performed on one eye at a time by covering the eye not being tested.
Your pupils. Your doctor may evaluate how your pupils respond to light by shining a bright beam of light through your pupils. Common pupillary reaction to this stimulus is to constrict (become smaller). If your pupils respond by dilating (widening) or there is a lack of response either way, this may indicate an underlying problem.
Your side vision. Loss of side vision is a symptom of glaucoma. Because you may lose side vision without knowing it, this test can identify eye problems that you aren't even aware of.
Your eye movement. This test, called ocular motility, evaluates the movement of your eyes. Your ophthalmologist will want to ensure proper eye alignment and ocular muscle function. Common tests measure the eyes and their ability to move quickly in all directions and slowly track objects.
Your prescription for corrective lenses. You will be seated and asked to view an eye chart through a device called a phoroptor, which contains different lenses. The phoroptor can help determine the best eyeglass or contact lens prescription to correct any refractive error you may have, such as myopia.
Your eye pressure. This test, called tonometry, measures the pressure within your eye (intraocular eye pressure, or IOP). Elevated IOP is a sign of glaucoma. The test may involve a quick puff of air onto the eye, or gently applying a pressure-sensitive tip near or against your eye. Your ophthalmologist may use numbing drops for this test for your comfort.
The front part of your eye. A type of microscope called a slit lamp is used to illuminate the front part of the eye, including the eyelids, cornea, iris and lens. This can reveal whether you are developing cataracts or have any scars or scratches on your cornea.
Your retina and optic nerve. Your ophthalmologist will put drops in your eye to dilate, or widen, your eye. This will allow him or her to thoroughly examine your retina and optic nerve, located at the back of your eye, for signs of damage from disease. Your eyes might be temporarily sensitive to light for a few hours after they are dilated.
Your ophthalmologist may suggest additional testing to further examine your eye using specialized imaging techniques such as OCT, topography or fundus photos. These tests can be crucial in diagnosing a disease in its early stages and allow your doctor to detect abnormalities in the back of the eye, on the eye's surface or inside the eye.
Each part of the comprehensive eye exam provides important information about the health of your eyes. Make sure that you are getting a complete examination as part of your commitment to your overall health.
A Note on Glasses
Glasses come from many vendors. With each vendor there are differences. Marion Eye Center Optical is different as well.
We consider glasses as important as any treatment, medicine or surgery. Their quality and accuracy determines the ease of activities each and every day for the patient. So, while we do offer frames, lenses and coatings from expensive to inexpensive, all our glasses are of uncompromising quality.
As you consider your next pair of glasses, consider shopping with us and seeing why we should be your one and only source for glasses.
Types Of Glasses
Distance glasses: Basic glasses for near or farsightedness are an important part of a person's daily life. Quality lenses, edge treatment, proper centering and distancing of lenses in the frame are all critical to keep details and life's events in focus and enjoyable.
Lined Bifocal: Not everyone prefers newer technology that has moved most wearers into progressive, no-line bifocals. Whether advanced technology, or traditional, lined bifocals, quality fit, centering, and height adjustments are critical for glasses to be helpful instead of troublesome.
Progressive ("no-line") glasses: All progressive lenses are not the same. There are progressive lenses that distort, but are cheap, and there are progressive lenses that are expensive, but no better than others costing less. You need good guidance to make the most of your money when purchasing these lenses. Shopping for progressive lenses is more than just sampling price-points. A careful consideration of the many options and lens-types will guide your choice and determine whether such lenses will be a frustration or beneficial.
Prescription or Stock Sunglasses: Sunglasses are more than just something we use when Summer rolls around. Instead, they are protection against future changes to vision. To us, sunglasses are certainly fashionable and helpful implements for controlling the brightness of the sun, but further, they are protective against eye diseases such as cataract and macular degeneration. When sunglasses are chosen, we include in our recommendation, thoughts of eye heath as well.
All contact lenses require a prescription.
A Note on Contact Lenses
A contact lens is a thin, curved disk which floats on the surface of the eye (cornea), providing vision correction. With advances in optical technology, almost everyone now can wear contact lenses, regardless the type or extent of their vision correction needs. Hard contact lenses range from rigid discs to soft, from distance only to bifocal, and from spherical to astigmatic correcting.
At Marion Eye Center Optical, we fit many typical contact lenses but are unique in the fitting of specialty and difficult contact lens fitting. If you simply want the best vision, fit and feel for a contact lens, or if you have had troubles with contact lenses and the comfort you experience when wearing them, ask to see one of our doctors today.
Types Of Contact Lenses
Daily Disposable Lenses: Daily disposable contact lenses are intended to be thrown out and replaced after you've worn them for the day. They are even easier to maintain than regular soft contacts because they require no cleaning or disinfecting. Daily disposable lenses are also a very healthy option since any bacteria that forms on the lens during the course of the day is disposed of that night and a fresh, clean lens is used the following morning.
Rigid Gas Permeable Lenses (RGP): Not as in vogue as soft lenses these contact lenses still serve their purpose as being superior for some focusing problems of the eye. Your doctor can determine whether RGP lenses will be the most suitable and give you the best vision possible.
Toric Lenses: Toric contact lenses are designed to correct for astigmatism. For those patients with astigmatism, part of the cornea has an oblong shape, which can make it difficult to achieve clear vision with a typical soft contact lens. Toric lenses have two different powers of correction in order to maximize vision and accommodate the astigmatism. They are available in a variety of forms, including daily, weekly and monthly disposables, as well as with colored options.
Progressive Toric Lenses: Progressive toric contact lenses are a variant of toric lenses that not only correct astigmatism, but also vision problems due to presbyopia. Presbyopia is a natural change in the ability of our eyes to focus that occurs to most people as they age. Presbyopia causes small or close-up objects to appear blurry. Progressive toric lenses offer multiple powers of correction all in one lens to provide sharp vision at a range of distances to those with astigmatism.
All contact lenses require a prescription and ongoing examinations to prevent long-term complications
