Who is an optometrist?
The eyes are among the most critical and delicate parts of the body, requiring special care. Optometrists are experts who specialize in eye care. In addition to treating eye-related disorders, optometrists offer their expertise on vision and vision care problems.
They also know about treating vision-related conditions like myopia or presbyopia, registering aids for low vision, providing vision therapy, etc. In some instances, optometrists and ophthalmologists often collaborate to provide better treatment and diagnosis.
What kind of education and training do optometrists receive?
To provide excellent primary eye care or vision care, one must undergo years of training and education. To practice as an optometrist in the United States, one must finish a four-year undergraduate degree and an additional four years in a professional optometry program. After completing optometry school, some practitioners in the United States also complete a fellowship or clinical training where they specialize in a subspecialty.
During their fellowship, optometrists learn to perform eye exams, conduct vision tests, prescribe contact lenses and eyeglasses, and treat eye-related conditions like glaucoma.
Different types of eye and vision care specialists
The main categories of vision care specialists are as follows:
- Ophthalmologist - An ophthalmologist is a healthcare specialist or osteopathic doctor specializing in treating and diagnosing issues related to eye and vision. Unlike other eye care specialists, ophthalmologists and eye physicians have received advanced surgical and medical training. They are licensed to perform surgeries. Ophthalmologists are required to undergo 12 to 13 years of education and training. In addition to treating and diagnosing all eye or vision-related diseases, some ophthalmologists also train in sub-specialties in areas like the retina, cornea, glaucoma, etc.
- Optometrist - An optometrist is an eye care expert who provides primary care for eyes and vision-related issues. Optometry allows physicians to treat, examine, and diagnose common problems like low vision, blurry vision, glaucoma, myopia, presbyopia, cataracts, macular degeneration, etc. Unlike ophthalmologists, who complete a Doctor of Medicine (M.D.) degree, optometrists obtain a Doctor of Optometry degree. Since they do not have a degree in medicine or training in surgery, optometrists are not licensed to perform eye-related surgeries.
- Optician - An optician is a vision care expert specializing in treating and diagnosing eyesight and vision-related issues. Their practice focuses on designing and dispensing lenses to correct vision problems. Vision problems can occur for various reasons like poor vision practices, genetic makeup, physical trauma, etc. Opticians train to fix contact lenses, low vision aids, ophthalmic prosthetics, spectacles lenses, etc. To practice as an optician, one must earn an optical science degree. Opticians and optometrists often work together to correct eyesight problems. Opticians like optometrists and ophthalmologists do not undergo intense and prolonged residency programs or fellowships. Opticians cannot perform eye-related surgeries or treat eye disorders like glaucoma.
Types of eye disorders optometrists treat
An optometrist near you can help you prevent, diagnose, and treat various eye disorders, some of which are as follows:
- Glaucoma - Glaucoma is a prevalent cause of loss of eyesight. Glaucoma can affect any age group; however, it is common in the older population. It is a severe eye disorder that damages the optic nerve. This nerve plays a pivotal role in sending nerve signals from the eyes to the brain. Damage to this nerve could result in vision problems. The damage is due to the high pressure in the optic nerve area caused due to increased fluid build-up in the eye. Glaucoma is often challenging to diagnose and treat as it is tough to detect in the early stages. During the early stage, glaucoma shows no warning signs; only when it significantly progresses can one notice vision changes.
- Color blindness - Color blindness is a severe vision condition where a person visualizes colors differently than someone with normal vision. People often generalize the term color blind and assume that a person who is color blind can only see the shades of black and white, but this only happens in rare cases. People with color blindness cannot distinguish between certain shades of colors like green, yellow, red, etc. Color blindness often occurs due to genetic makeup, and men are more prone to be born with this condition.
- Cataracts - A cataract is a condition where the usually transparent lens in the eye turns opaque. This layer makes it extremely difficult for the person to see things. A person with a cataract might find it challenging to perform basic activities like reading the newspaper, driving a car, reading billboards, etc. Cataracts often develop slowly over time, which makes it extremely challenging to identify in the early stages. Symptoms include clouded vision, dim or blurry vision, yellowing of colors, sensitivity to light, double vision, and the need for brighter lighting while reading.
Standard vision tests that optometrists perform
Optometrists help in diagnosing all kinds of ocular conditions, including vision disorders. As part of an eye exam, they perform various vision tests. The standard ones include -
- Visual acuity - It is the standard test that eye providers perform to decide whether a patient needs glasses. If they do, this test also helps find the right lens to correct the vision problem. During this test, the patient covers one eye alternately and reads from a Snellen chart.
- Automatic refraction - Autorefractors check the visual acuity in patients who cannot read, such as young children and people who cannot speak clearly. They measure the eye's response and decide whether a corrective lens is needed.
- Visual field - This test helps scrutinize a patient's vision range. Optometrists move a finger or an object side to side, up and down, and near and far. The patient follows it only with the eyes without turning the head.
- Color vision test - This is the standard test for detecting color blindness. The optometrist shows the patients several images containing colored dots and hidden numbers, and they have to find and read the numbers.
- Ophthalmoscopy - Also known as fundoscopy, this test helps optometrists examine the lens, cornea, retina, optic nerve, and blood vessels. The provider dilates the eyes using eye drops and then shines a handheld instrument to study the various parts of the eyes.
- Corneal topography - In this test, a computer takes several measurements of the patient's cornea and produces a corneal map. Optometrists use this test to study the curvature of the patient's eyes and diagnose astigmatism. Corneal topography also aids providers during corneal transplants, lens fitting, and other ocular surgeries.
- Slit-lamp exam - The optometrists begin this test by dilating the eyes using eye drops. Once they dilate the pupils, they use a slit-lamp microscope to magnify the various parts of the eyes and study them.
- Tonometry - This is one of the standard tests for detecting changes in eye pressure and diagnosing glaucoma. After numbing the eyes using drops, the optometrists blow a tiny puff of air with a tonometer. The provider then proceeds to measure the pressure needed to flatten the eyes.
- Optical coherence tomography (OCT) and fundus photography - These are imaging tests used to examine the different parts of the eye.
How to keep your eyes healthy?
The eyes are highly sensitive organs requiring the utmost care to ensure well-being. Prevention is better than cure when it comes to your eye care. Instead of rushing to an optometrist near you in an emergency, it is prudent to take preemptive measures.
Maintaining good eye health involves making minor adjustments to your daily routine. By including these changes, you can reduce the risk of common eye disorders like age-related macular degeneration and cataracts as you age. Here are some steps to promote eye health:
- Quit smoking: Smoking increases the likelihood of cataracts and damages the optic nerve, leading to macular degeneration. If you've struggled to quit before, continue your efforts and consider seeking assistance from your doctor.
- Use sunglasses: You must protect your eyes from harmful UV rays by choosing sunglasses that block approximately 99% to 100% of UVA and UVB rays. Opt for wrap-around lenses for additional side protection. Even if your contact lenses have a UV protection feature, wearing sunglasses adds an extra layer of defense.
- Wear protective eyewear: Use sun glasses or goggles when handling hazardous materials or participating in sports with potential eye injury risks. For sports like ice hockey, racquetball, and lacrosse, wear appropriate eye protection such as helmets with face masks or sports goggles that have polycarbonate lenses to protect your eyes.
- Schedule regular eye checkups: Routine visits to an ophthalmologist or optometrist are essential for individuals of all ages, including children. These examinations help maintain a healthy vision and serve as a preventive measure by detecting conditions like glaucoma early, even when symptoms are absent. Early identification enables more effective and manageable treatment.
What should one expect during an eye exam?
During an eye exam, the optometrist will begin by asking about your vision, any recent changes or concerns, and any significant medical events or life changes you may have experienced. After this initial discussion, they will guide you through various examination components. Depending on your circumstances, they may suggest additional tests, which your eye care provider can explain in detail.
One common procedure is pupil dilation, which allows your eye care specialist to examine the interior of your eye more thoroughly. To dilate your pupils, they will use eye drops that temporarily relax the muscles, controlling pupil size and making them wider. This provides a clearer view of areas that might not be visible otherwise.
If you have a refractive error and need corrective lenses, the optometrist will assess the degree of this error in each eye. This assessment helps them prescribe glasses that will correct your vision. They may also take specific measurements of your eyeball, which are necessary if you are interested in wearing contact lenses.
After your routine eye exam, the optometrist will discuss their findings and what they mean for your vision. You will get a paper or digital copy of your prescription if corrective lenses are needed. Federal regulations say optometrists must provide this document, even if you do not wish to have it. In some states, providers must also include your pupillary distance—the distance between your pupils—on the prescription, which is important for purchasing glasses online. However, this measurement is not always mandatory, so it’s advisable to ask for it if needed.
If the specialist dilated your pupils during the exam, you may find it difficult to focus on nearby objects, such as your phone or computer screen, for a while. Bright lights, daylight, and screens might also appear uncomfortably bright or painful. To ease the discomfort, consider bringing sunglasses to your appointment to wear afterward.
