Who are optometrists?
Optometrists are healthcare providers who provide vision care. They are not medical doctors. However, they are licensed to practice optometry in states. They can write prescriptions for corrective tools such as lenses and glasses, conduct eye exams, find abnormalities, and even treat some eye conditions such as macular degeneration and glaucoma. Optometrists monitor and treat eye issues related to cataracts, vision loss, blindness, diabetic retinopathy, etc.
Education and training of optometrists
Aspiring optometrists need to first complete a bachelor's degree in pre-med or related science subjects. Following this, they must pass the Optometry Admission Test (OAT) to gain entry into a four-year Doctor of Optometry (O.D.) program. Upon completing their O.D. degree, they undergo examinations held by the National Board of Examiners in Optometry to obtain licensure and commence practice. Additionally, optometrists have the option to pursue fellowships for specialized training in specific areas of eye care if they so choose.
Subspecialties within optometry
Here is a brief overview of the subspecialties within optometry:
- Pediatric optometry: Pediatric optometrists specialize in providing eye care to children, including detecting and managing vision problems and eye conditions specific to young patients.
- Geriatric optometry: Geriatric optometrists specialize in addressing the unique eye care needs of older adults, like age-related macular degeneration, diabetic retinopathy, etc.
- Low vision: Optometrists in this specialty work with individuals with significant visual impairments, which are usually impossible to fully correct with traditional eyeglasses, contact lenses, or surgery. They assist patients in optimizing their remaining vision and improving their overall quality of life.
- Neuro-optometry: Neuro-optometrists specialize in assessing and managing vision problems related to neurological conditions. These include trauma, neurological diseases, or congenital (present at birth) conditions.
- Cornea and contact lens specialty: These optometrists specialize in fitting and managing various contact lenses, including specialized lenses for patients with complex corneal conditions.
- Ocular disease specialty: Optometrists specializing in ocular disease diagnose and manage multiple eye conditions affecting the front and the back of the eye. These include glaucoma, macular degeneration, and other disorders that can lead to vision loss.
- Vision therapy/behavioral optometry: Also known as behavioral optometry, it focuses on how visual function influences your everyday activities. Behavioral optometrists may seek to enhance visual function through vision therapy, including eye exercises and specialized prisms and lenses.
- Sports vision optometry: These optometrists work with athletes to optimize visual performance for their specific sports. They help improve depth perception, peripheral awareness, eye-hand coordination, the ability to monitor a moving object, and the ability to focus and perform effectively even under pressure.
Why should you see an optometrist?
You should promptly make an appointment with an optometrist if you are experiencing eye pain, double or blurred vision, flashes of light, halos around lights, redness or irritation in the eyes, or specks floating before the eyes. They also conduct routine eye examinations that you must take if you wear or need glasses, have chronic conditions like diabetes, vision loss, or eye disease in your family, or take prescription medications that can impact the eyes.
Before making an appointment with an eye doctor near you, you must understand the difference between an optometrist, an ophthalmologist, and an optician.
Optometrists differ from ophthalmologists and opticians, who are also vision care professionals. Ophthalmologists can perform eye surgery, thus making them capable of more comprehensive eye care than optometrists. Opticians, on the other hand, are technicians who interpret prescriptions that are issued by ophthalmologists and optometrists so that they can fit and sell suitable spectacles and other eyecare devices.
What are cataracts?
The lenses of the eyes usually are clear. They become cloudy when a cataract develops. Seeing through a cataract-affected lens resembles looking through fogged-up or frosted glass. It can lead to difficulty reading, driving, or even seeing expressions on people's faces, especially at night. Dimmer vision, sensitivity to light and glare, fading or yellowing colors, double vision, the need to often switch out eyeglasses or lenses, etc., are some other typical cataract symptoms.
Cataracts develop slowly and only lead to vision disturbances much later. Initially, you can navigate cataracts through eyeglasses or by using stronger lighting. This is because the condition initially affects only a tiny part of the lens and continues to grow in size. Later, the cataract distorts the light that passes through the lens, leading to more noticeable symptoms.
A cataract generally develops due to changes in the tissue that make up the lens. These are typically due to aging or any injury. As a result, proteins and fibers break down, and vision becomes hazy. People with diabetes, obesity, high blood pressure, previous eye surgery, injury, or inflammation are at higher risk of developing cataracts. Some lifestyle choices like smoking, excessive alcohol consumption, and prolonged usage of steroids can also increase the chances of encountering a cataract.
How to prevent cataracts?
To prevent cataracts or slow their progression, your optometrist may suggest adopting and implementing the following strategies:
- Frequent eye examinations to screen for them and identify them at an earlier stage.
- Quitting smoking and excessive alcohol consumption reduces your chance of developing cataracts.
- Wearing sunglasses that block ultraviolet B rays outdoors can also eliminate another possible risk factor for cataracts.
- If you have other health problems like diabetes, follow your treatment plan correctly, as diabetes can cause blurry vision.
- Enriching your diet with colorful fruits and vegetables is an efficient and healthy way of obtaining antioxidants, vitamins, and minerals that can be very useful in preventing cataracts.
In case of the development of a cataract, safe and effective cataract surgery can help remove it from your eye lenses, restoring your vision to clear.
What are the nutrients that help to optimize eye health?
There are many nutrients obtained from food that can help enhance your vision health. These include the following:
- Vitamin A: Vitamin A, also known as retinol, is responsible for producing the retinal pigments in the eye. It is an essential for the health of photoreceptors, determining vision quality in low-light conditions. Vitamin A is only found in animal products. However, the body has the ability to convert some plant nutrients into vitamin A. Food sources rich in vitamin A are egg yolks, dairy, liver, spinach, other dark leafy greens, and carrots.
- Vitamin C: It is found in the aqueous humor fluid in the eye lenses. Experts believe that Vitamin C, being an antioxidant, can help prevent age-related cataracts. Since the body is unable to produce it on its own, eating fruits and vegetables like broccoli, kale, peppers, and oranges – which are rich in vitamin C – is vital.
- Vitamin E: It is a group of compounds called tocotrienols and tocopherols. These compounds protect fatty acids from oxidation in the body, safeguarding the eyes from oxidative damage. Though vitamin E deficiency is very rare, it can be concerning if it occurs. Hence, consuming foods like almonds, sunflower seeds, and avocados can help maintain optimal vitamin E levels in the body.
- Fatty acids: Fatty acids are compounds that the body creates during fat digestion. These support various functions of the eyes. Two fatty acids notable for good eye health are omega-3 and gamma-linolenic acid (GLA). Omega-3, found in salmon, mackerel, sardines, flaxseeds, chia seeds, and walnuts, contributes to the structure of eye cell membranes supporting visual function. They also have anti-inflammatory properties, which can help reduce symptoms of dry eye syndrome, glaucoma, and age-related macular degeneration. Likewise, GLA, with its anti-inflammatory properties, can help prevent dry eye syndrome, diabetic retinopathy, and cataracts. Good sources of GLA include primrose oil, borage oil, black currant seed oil, hemp seeds, and spirulina.
For personalized advice, it is best to consult an expert, like an optometrist.
What to expect at your optometrist appointment?
When visiting an optometrist near you, expect a comprehensive vision and eye health evaluation. Initially, they will inquire about your medical history and any specific vision concerns you may have. Here is what typically occurs during an optometric examination:
- Cover test: This test evaluates the coordination of your eyes by observing their movement while focusing on a target at a set distance. Each eye is alternately covered and uncovered to assess individual eye function.
- Eye muscle movement test: This assesses the alignment of your eyes. The practitioner observes your eye movements as you track a target, such as a fingertip or a pen, moving in various directions.
- Pupil reactions: The optometrist examines your pupils' response to light changes and observes the condition of your eyelids and the white part of your eyes.
- Visual acuity: A visual acuity test entails covering one eye and reading various lines of an eye chart, starting from the largest letters at the top and progressing to the smallest letters at the bottom. This will help determine whether corrective lenses are needed or not.
- Refraction test: For precise lens prescriptions, a doctor can employ a computerized refractor. They will refine the prescription by alternating between lenses with a phoropter and asking for your input on which provides better clarity. If corrective lenses are not required, this test will not be conducted.
- Slit lamp exam: Your optometrist will utilize a specialized instrument to magnify and illuminate the front part of your eye, which includes the cornea, iris, and lens, ensuring a comprehensive examination.
- Retinal exam (ophthalmoscopy): An ophthalmoscope inspects the back of your eye, encompassing the retina, optic nerve, and blood vessels.
Additionally, an optometrist will measure intraocular pressure for signs of glaucoma, assess corneal thickness, and evaluate peripheral vision.
Remember to carry your current glasses or contact lenses to ensure an accurate prescription assessment. If dilation is necessary, bring sunglasses, as your eyes may be light-sensitive afterward.
