Do I really need an eye exam every year?
Absolutely! Your eyes are important, which is why here at Buenau's Opticians, your vision care is our top priority, and it all starts with an annual eye exam. It's important to understand that annual eye examinations are much more than just a simple vision check. It is fairly complicated process that not only checks your visual accuity, but also neurological function, eye pressure, eye muscle coordination, and the overall health of the external and internal structures of the eye. There are several serious eye diseases that are asymptomatic in the early stages, which is why early detection and treatment plays such a crucial role in preventing vision loss. Conditions such as macular degeneration, glaucoma, and cataracts develop so gradually over time that many patients fail to realize there is a problem until serious damage has already occurred.
Why do I have to get an annual eye exam if I wear contacts?
Contact lenses are a medial device regulated by the FDA, and it's because of this that annual exams and contact lenses evaluations are required by law. Besides making sure your prescription is up-to-date, eye doctors check the health of your eyes, the curvature of your corneas, and inspect your eyes for microscopic related complications associated with wearing a contact lenses. As we get older, so do our eyes, and a small problem today - left unchecked - could turn into a serious problem down the road. You only get one set of eyes, so why chance anything? At Buenau's Opticans, we pride ourselves in specializing in the hard-to-fit contact lens patient. With our wide selection and great prices, you can be assured that we will do everything possible to make sure that you're wearing the safest contact lenses possible.
When should I have my child's eyes examined?
Many parents often wonder just how well their children can see. Typically at around six months and again at 3 years of age, most pediatricians screen kids for potential eye problems, but it is a general screening. If you are concerned about your child's vision health, or have a family history of childhood eye problems, then your child should be seen by an optometrist. It is also recommended that a full comprehensive eye examination be performed between the ages of 4 and 6 years of age, because at this point, children are entering school. Studies show that undetected vision problems at a young age can contribute to learning disabilities, bad behavior and poor grades.
Am I a candidate for Laser Vision Correction?
In most cases, LASIK or PRK can treat degrees of nearsightedness, farsightedness and astigmatism. However, LASIK or PRK eye surgery is not right for everyone, and it's important to understand the risks, benefits, and side effects of treatment. Only after a comprehensive examination and consultation by our licensed optometrists can it be determined if you fit the general requirements for surgery. The goal of Laser Vision Correction is to reduce your dependency on glasses or contact lenses, and in most cases can result in the successful improvement of ones visual acuity. So if you're interested in finding out whether LASIK or PRK eye surgery is right for you, call today and schedule an appointment.
So I scheduled an eye exam, what can I expect?
A complete eye exam involves a series of tests designed to evaluate your vision and check for eye diseases. First and foremost, it doesn’t hurt. The doctor may use odd-looking instruments, aim bright lights directly at your eyes, and request that you look through a seemingly endless array of lenses. Each test evaluates a different aspect of your vision.
The eye exam usually begins with your doctor asking about your medical history and any vision problems you might be experiencing. Next, your eye doctor makes a quick check of your eyes using a light to ensure the exterior parts of your eyes are functioning correctly. Finally, your doctor measures your visual acuity, assesses your need for glasses, and examines your eyes for signs of disease. The doctor may also preform a retial examination to exam the structures in the back of you eyes. Usually before your doctor can see these structures, your pupils must be dilated with special eye drops.
The doctor will in some cases, besides these common tests performed during a standard comprehensive eye exam, may recommend other – more specialized eye tests. Often, such tests are performed by other eye doctors, such as retinal specialists, on a referral basis.
Will I be able to drive myself home if my eyes are dialated?
Most patients can comfortably drive home if they have sunglasses. However, if you are unsure about driving while your eyes are dilated, please be safe and bring another driver with you to your examination.
Laser Vision Correction
Laser Vision Correction (LASIK or PRK) is the most technologically advanced method for correcting nearsightedness (myopia), astigmatism, and farsightedness (hyperopia). Using an excimer laser, the precise, effective procedure can help reduce or even eliminate your dependence on glasses and contact lenses. Over one million laser vision correction procedures have been performed in 52 countries, in the past decade.
FACT: Tiger Woods was a -11 prior to his LASIK surgery, which is in the worst one percent of those with nearsightedness. Tiger was considered to be legally blind without his glasses or contacts. Prior to LASIK surgery, without his glasses or contacts, he would not have even been able to see the ball on the tee.

The human eye is a delicate and complex organ that converts light waves into impulses that are then interpreted by our brains as images. It is considered by many in the scientific and medical communities to be the most complex organ in our bodies. Below is an overview of the components of the human eye and how the process of sight works.
Parts Of The Eye
Cornea: Located at the front of the eye, the cornea is a transparent layer of tissue that focuses light into the pupil.
Iris: The colored part of the eye that controls the expansion and contraction of the pupil depending on the amount and intensity of the light that enters the eye.
Pupil: Located in the center of the iris, the pupil controls how much light enters the internal structure of the eye. In humans, the pupil is round, and it appears black, because the light that enters the pupil is absorbed by the inner eye.
Lens: Located directly behind the pupil, the lens (along with the cornea) helps to focus light onto the retina
Retina: A light-sensitive layer of tissue, the retina is a membrane located at the back of the eye that converts light into electrical impulses.
Photoreceptors: (sometimes called rods and cones) are specialized cells used by the retina to process and convert light
Optic Nerve: Located behind the eye, the optic nerve is a bundle of nerve fibers that transmits the impulses generated by the retina to the vision centers of the brain.
Macula: Part of the retina, the macula is responsible for central vision. It's highly specialized structure is responsible for visual acuity.
Sclera: The white part of the eye, the Sclera is made of fibrous tissue and is designed to protect the inner workings of the eye.
Choroid: Located between the retina and the sclera, the choroid is the vascular layer of the eye.
How It All Works
The ability to see is a complex and delicate process that requires the various parts of the eye as well as the vision centers of the brain to work in concert. The process begins as light waves enter the eye through the cornea. As the primary focusing element of the eye, the cornea bends and focuses the light so it can pass through the pupil and enter the inner structures of the eye.
The pupil, which is controlled by the ring of muscles known as the iris, contracts and expands to limit the amount/intensity of light that enters the inner eye. In bright conditions, the pupil will contract, and in low light conditions, the pupil will expand.
Once through the pupil, the light then passes through the eye's secondary focus structure called the lens. Unlike the cornea, which is fixed, the lens has the ability to change shape, which allows the light to be fine tuned to a sharp focus before it passes onto the retina.
The retina works much like the film in a camera. It's an intricate layer of light-sensitive tissue that lines the inner surface of the eye made up of photoreceptor cells (sometimes called rods and cones). As light hits the retina, it initiates a surge of chemical and electrical events that ultimately trigger nerve impulses. These impulses then travel through the optic nerve, located behind the eye, into the vision centers of the brain which finally get interpreted into the images we see everyday.
As you can see, it is an extremely delicate system with several working parts. Just a slight defect, like the curvature of the lens, the shape of the cornea, or damage to the retina can cause sometimes significant vision problems. That is why taking care of your eyes is critically important. Buenau's Opticians recommends all patients receive an annual eye exam. Early detection and prevention of several common eye disorders can significantly reduce eye damage and prevent vision loss.
