What is optometry?
Optometry is the field of healthcare that examines the eye and its parts, such as the cornea, retina, iris, and supporting structures. Professionals trained in optometry are referred to as optometrists. Their expertise involves conducting eyesight checkups and diagnosing any abnormality in the surrounding systems of the eyes.
People tend to overlook the importance of having healthy eyesight. In a recent American Optometrists Association (AOA) survey, about one-third of Americans believed they didn't need an eye checkup if they could see clearly. A comprehensive eye exam is for more than just those with blurry vision. You can discover vital information about the health of your eyes and your body in general with regular eye checkups. This is why periodic appointments with your optometrists significantly affect your overall well-being.
Who is an optometrist?
Optometrists are healthcare practitioners who specialize in primary vision care. Although not medical doctors, they are licensed to perform optometry. In most cases, these primary eye healthcare providers are adept at conducting vision exams and diagnosing severe eye diseases. They can prescribe contact lenses and spectacles after an eye test. Optometrists are also trained to spot eye-related manifestations of systemic illnesses like uncontrolled diabetes, hypertension, shingles, etc.
What training does an optometrist undertake?
The average optometrist attends college to finish their bachelor's in science or pre-medicine degree. Later, they must clear the Optometry Admission Test (OAT) to enroll in four years of optometry school. On course completion, they are rewarded with a Doctor of Optometry (OD) degree. Optometrists must go through the National Board of Examiners in Optometry (NBEO) exams to become certified practitioners.
When to see an optometrist?
Below are some of the common reasons why you should consider seeking an optometrist:
- You have trouble seeing objects.
- You have a family history of eyesight-related disorders like short-sightedness, long-sightedness, or astigmatism.
- Your eyes are always dry or itchy.
- You have high blood sugar levels that make you prone to eye diseases.
- Your blood pressure is high, putting you at risk of eye disease.
- You have severe headaches and episodes of blurred vision or halos around lights.
- You have a burning sensation in the eyes.
- You can see specks of dust that float right in front of your eyes.
- You need help seeing an optometrist during the evening and night.
What to expect at your first appointment with an optometrist?
On the first visit to the optometrist's office, they will inquire about your chief complaint. Once questions regarding how long you have had the issue have been answered, they record your personal and familial medical history. History-taking is integral to diagnostic evaluation as many eye diseases have a family/genetic origin.
The optometrist will then perform a visual acuity test to determine the power in both eyes. They will make a prescription if you need glasses or contact lenses to rectify your eyesight. A Snellen's chart that contains different lines of letters in varying sizes is often used in this test. You will be instructed to read aloud the letters from a screen or board placed six feet away. Some other tests the optometrist will perform are:
- Visual field test: The peripheral vision test assesses your ability to see around corners without shifting your eyes. Often, the doctor moves a finger or mini torch into and out of your peripheral vision to help you spot it.
- Slit-lamp test: It allows the eye doctor to inspect the front of your eye, including your eyelids, lashes, cornea, iris, lens, and fluid chamber.
- Fundus photography: This test involves taking digital images of the fundus or the ‘back of the eye.’ The fundus is an integral part of the eye that houses the retina, optic disc, and blood vessels that nourish the eye. Also known as an ophthalmoscopy or funduscopy, the test requires dilation of your pupils.
- OCT screening: OCT stands for optical coherence tomography, and your eye doctor uses it to diagnose eye and optic nerve disorders.
- Glaucoma screening: The fluid pressure inside your eye should be optimum for good vision. Intraocular pressure increases in glaucoma, leading to impaired vision. Your optometrist is more likely to conduct the test if you are older than 40 and have a family history of glaucoma.
What is the difference between an optometrist and an ophthalmologist?
Navigating the choice between an optometrist and an ophthalmologist can perplex individuals seeking an eye doctor near them. Despite both professions addressing vision-related concerns, distinctions between them often lead to widespread confusion. Recognizing these disparities is crucial for ensuring timely and appropriate eye care. Both optometrists and ophthalmologists play essential roles, yet their varying expertise and training significantly set them apart.
Optometrists specialize in vision testing, correction, and managing changes in vision, serving as accessible eye doctors near you. It is essential to note that optometrists do not hold medical doctor status. In contrast, ophthalmologists are highly specialized medical doctors exclusively dedicated to comprehensive eye and vision care.
The fundamental contrast lies in their scope of education and practice. Ophthalmologists undergo college education and at least eight additional years of medical training, granting them medical and surgical practice licenses. They have the expertise and knowledge to diagnose and treat various eye diseases, prescribe corrective lenses, and conduct surgical procedures to address various vision issues, making them crucial eye doctors for specialized interventions.
Ophthalmologists can specialize as subspecialists by dedicating an additional one or two years to intensive training, known as a fellowship. This specialized training focuses on specific areas such as glaucoma, retina, cornea, pediatrics, and more. It equips these experts to handle intricate or condition-specific cases within particular eye regions or patient demographics.
Optometrists are reliable and accessible eye doctors near you for routine eye care, such as annual exams or prescription renewals for glasses, contact lenses, or eye medication. On the other hand, when facing severe eye conditions like glaucoma, cataracts, or the need for laser eye surgery, an ophthalmologist is the specialist best equipped to provide the necessary expertise and intervention.
Making an informed decision based on the nature of your eye care needs ensures that you receive effective treatment, with the convenience of consulting an eye doctor near you for routine care and specialized interventions when necessary.
How do you maintain good eye health?
Here are a few things to help keep your eyes healthy and improve your vision:
- Consume a healthy diet consisting of fresh fruits and vegetables. This will help you get the nutrition your eyes need to stay healthy.
- Exercise regularly. This helps improve blood circulation, which can, in turn, help improve vision.
- Always carry sunglasses to protect your eyes from harsh UV rays.
- Get regular eye exams. This is important so that potential eye problems can be detected early and treated before they become bigger issues.
Understanding eyesight changes as people age
Starting in your early to mid-40s, you may notice it's harder to see up close, particularly when reading or working on the computer. Known as presbyopia, this is a common issue for adults between 41 and 60 and results from the eye's focusing ability gradually declining.
Some evident and observable signs of presbyopia include holding reading materials farther away or removing your glasses to see things up close. Blurry print, especially in dim lighting, maybe a new challenge. Fortunately, if you already wear prescription glasses or contacts, options like bifocals or multifocal lenses can help restore near vision.
This age is also an excellent time to prioritize eye health by scheduling a comprehensive eye exam every two years. Driver's license or other basic vision screenings often miss subtle eye problems that regular exams can catch early. Some adults over 40 are especially at risk for eye issues, including those with:
- Chronic conditions such as diabetes or high blood pressure
- Family history of glaucoma or macular degeneration
- Vision-intensive or hazardous jobs
- Health issues like high cholesterol, thyroid imbalances, or arthritis that require medications with potential vision side effects
Just as your body ages, so do your eyes. Not everyone experiences the same symptoms, but here are some typical changes:
- Need for more light: Brighter lighting becomes essential as you age to perform close-up tasks comfortably.
- Close-up vision challenges: Printed material may appear less clear as the eye's lens becomes less flexible. This change makes it difficult to focus on nearby objects.
- Increased glare sensitivity: Due to changes in how light is processed in the eye, glare from headlights at night or reflections from sunlit surfaces may become more bothersome.
These natural changes underscore the importance of regular eye check-ups with an optometrist near you to maintain clear, comfortable vision as you age.
What are the nutrients that help to optimize eye health?
Several different nutrients and diets can help optimize eye health. One of the best nutrients for eye health is omega-3 fatty acids, commonly found in fish like mackerel, salmon, and sardines. Other good nutrients for eye health include zeaxanthin and lutein, found in leafy green vegetables like spinach and kale, and carotenoids like beta-carotene, found in carrots.
A nutrition-rich diet can help keep your eyes healthy and lower the risk of developing specific eye ailments like macular degeneration and cataracts. Many nutrients can help optimize eye health, but some are more effective. Here are the best foods for eye health:
- Fatty fish: Fatty fish like tuna are rich in omega-3 fatty acids that alleviate the risk of dry eye syndrome and other age-related eye problems.
- Fruits and vegetables: Sweet potatoes and tomatoes contain beta-carotene, an antioxidant that can help decrease the risk of cataracts.
- Nuts and seeds: Nuts and seeds like pistachios, sunflower seeds, and almonds contain vitamin E. It is an antioxidant that protects against age-related eye diseases.
- Eggs: Eggs are rich in zinc, essential for healthy eyesight.
