Who are eye care specialists?
While healthcare in general and eye healthcare specifically can be complex and complicated, understanding specialists and their areas of expertise is critical in ensuring we pick the right provider for our healthcare needs.
The eye healthcare landscape is enormous and highly varied. Three categories of eye care professionals exist:
We shall further discuss the distinction between opticians, optometrists, and ophthalmologists to understand their expertise. Being aware of these differences is the first step in choosing the best healthcare provider for our requirements.
The three types of eye health professionals vary in their areas of expertise based on their education, skill sets, and scope of work. In terms of education, an optician needs the shortest training a year or two after graduating from high school. Moreover, opticians are eye care professionals who are not officially "eye doctors" and cannot conduct eye exams. Primarily, technicians are trained to fit frames and contact lenses to correct vision problems.
Optometrists must complete about four years of optometry school after a four-year college degree. They receive a "Doctor of Optometry (OD)" degree. They can perform assessments of the eye and vision, prescribe and dispense corrective lenses, detect eye abnormalities, and prescribe medications for eye diseases. Traditionally, they are not considered "medical doctors" and specialize in primary & essential eyecare consultations.
To become an ophthalmologist, students must attend medical school and complete a residency in ophthalmology. There is a critical difference between an optometrist and an ophthalmologist. Ophthalmologists can treat eye diseases, prescribe medication, and prescribe vision corrective gear; they can also perform surgeries to correct vision issues.
What are the subspecialties of ophthalmologists?
General ophthalmologists can undergo additional training to specialize in treating more complex and specific conditions. They become subspecialists who have added years of fellowship to their medical training. Moreover, you get recommended to them by an ophthalmologist when they assess that your condition needs more specific care.
The subspecialties include the following:
- Cornea: The clear frontal part of the eye, which shields the iris and pupil, is known as the cornea. These subspecialists diagnose and treat conditions such as keratoconus and Fuchs dystrophy. They focus on performing refractive eye surgery, corneal transplantation, complicated contact lens fittings, and corneal trauma.
- Retina: It is the light-sensitive tissue at the back of the eye, where a small area called the macula is responsible for vision. Retina specialists manage and diagnose various retinal conditions, including diabetic eye disease and macular degeneration. They perform surgeries and laser treatments and train in complex microsurgical techniques.
- Glaucoma: It is a medical condition affecting the optic nerve that bridges the brain and the eye. Hence, glaucoma specialists focus on surgically treating conditions that cause damage to the optic nerve. They use various treatments to manage eye pressure, including medications, surgeries, and lasers.
- Pediatrics: Pediatric specialists help diagnose and treat common eye diseases affecting children. These include conditions like vision differences between two eyes, uncorrected refractive errors, and misalignment of the eyes. They also perform detailed eye muscle surgery, intraocular surgery, and other treatment options.
- Oculoplastics: This specialty includes surgical procedures related to oculoplastics involving the bone and structure around the eyeball, eyelid problems, and the tear drainage system. Surgeons perform reconstructive and plastic surgeries to improve facial structures' function and visual appearance.
- Neuro-ophthalmology: These specialists diagnose and treat vision problems related to neurological disorders. Some common diseases include thyroid eye disease, multiple sclerosis, brain tumors, and strokes. They are proficient in knowledge of systemic neurological diseases with visual manifestations, optic nerve disease, eye-movement patterns, and visual pathways.
When should you see an ophthalmologist?
If the following conditions are reported and persist for a longer duration, you should visit an ophthalmologist near you:
- Persistent headache: Experiencing persistent headaches and painful tingling sensations in the brain can be good enough reasons to visit your eye doctor. Many eye problems trigger headaches, including complex issues such as glaucoma. Routine eye checkups can provide crucial early information about complex eye issues and their impact on eye health. People working on computer screens for hours often complain about pressurized eyes, which is also a reason for headaches.
- Infection of the eye: Our eyes are allergic to many things, such as pollens, dust, pet manure/waste, etc., that may soon become intolerable to their functioning and lead to infections. Symptoms may include red, itchy, dry eyes, blurry vision, and secretion. Make sure you visit your ophthalmologist as soon as you suspect any infections.
- Vision problems: One may suffer from vision problems such as dual vision, eye strain, and an increased floating material within the eye, which could be a symptom of some problem below your eyes. Vision problems could also signify a damaged retina; you should treat it urgently. If left untreated, the detached retina of the eye may lead to vision loss.
- Pain in the eye: In today's day and age, sustained exposure to computers and mobile screens is a primary cause of eye pain. However, if this pain persists for a while, then you must visit an ophthalmologist near you. More often than not, this could be an early symptom of eye dryness, which can be cured with some prescribed medicines. However, eye pain might be an indication of other serious eye diseases, such as injury in the cornea, glaucoma, or even an early sign of eye cancer.
- Frequent squinting: Squinting your eyes to focus on the blurred images before you. However, this temporary fix is not a sustainable way to deal with the issue of poor vision. Intermittent eye squinting is a valid reason for examining your eyes by an ophthalmologist, who may suggest a pair of glasses or contact lenses.
What is an eye exam, and what are the types?
An eye exam includes several examinations to detect vision-related issues and assess visual acuity. Ophthalmologists and optometrists typically perform these tests based on symptoms, and it is essential to provide them with relevant vision and health information for an accurate diagnosis. The following types of eye exams are commonly used:
- Eye muscle test: This test involves using moving objects to assess eye movement and identifying muscle weakness and issues with coordination and control.
- Refraction assessment: During this assessment, eye doctors use various tools, such as a computerized refractor or phoropter, to determine the lens prescription necessary for comfortable and clear vision.
- Slit-lamp examination: Slit lamps are used to examine the eyelids, iris, lashes, fluid chamber, and cornea.
- Visual acuity test: This test measures vision clarity by having patients identify letters or symbols on a printed chart or screen.
- Visual field test: Eye doctors use this test to evaluate the entire range of a patient's vision, using confront exams, manual testing, and automated perimetry.
- Color vision testing: This test involves showing patients various multicolored dot-pattern tests to identify color vision deficiencies.
- Retinal examination: This examination consists of inspecting the back of the eye, including the retina, optic discs, and retinal blood vessels, to detect any underlying issues.
What are baseline eye exams?
Children must undergo a vision screening as their eyes experience rapid growth and change. They may need to undergo a thorough eye exam conducted by an ophthalmologist. Four comprehensive eye exams throughout their life are recommended for adults with healthy eyes and good vision. This includes an exam in their 20s, two exams in their 30s, and one exam at the age of 40.
Regular eye examinations can help diagnose eye issues and changes in vision early. Early treatment can prevent vision loss even when symptoms are not noticeable. People with a higher risk of eye diseases due to diabetes, high blood pressure, or a family history of eye problems may require more frequent eye exams. For individuals over 65 years, eye exams should be conducted every one to two years. Irrespective of age, individuals who wear contact lenses should undergo a complete eye exam annually.
How do you maintain the health of your eyes?
Take care of your eyes by following these simple steps to keep them healthy, as recommended by ophthalmologists:
Quit smoking: Smoking raises the risk of optic nerve damage, cataracts, and macular degeneration. If you've tried quitting before, don't give up—each attempt improves your chances of success. For additional help, talk to your doctor.
Eat a balanced diet: Nutrients like lutein, zinc, and omega-3 fatty acids help protect against age-related vision issues, such as macular degeneration.
Use safety eyewear: When working with hazardous or airborne materials, it's essential to wear safety glasses to protect your eyes. The same applies to sports like ice hockey or racquetball, which pose a risk of eye injury. Wearing helmets with face shields or goggles made from polycarbonate lenses offers an added layer of protection for your eyes.
Wear sunglasses: Wear the right sunglasses to shield your eyes from harmful ultraviolet (UV) rays. Prolonged exposure to UV rays can raise the risk of developing cataracts and macular degeneration. Opt for shades that block 99-100% of UVA and UVB rays. Wraparound lenses provide side protection, and polarized lenses reduce glare while driving. Even if you wear UV-protective contact lenses, sunglasses are wise for added protection.
Take breaks from the computer screen. To minimize eye strain while using a computer:
- Ensure your glasses or contacts are appropriate for computer use.
- Consult your doctor if eye strain persists; they may recommend computer glasses.
- Adjust your monitor so your eyes are level with the top of the screen.
- Minimize glare from windows and lights, and use an anti-glare screen if necessary.
- If your eyes feel dry, blink more often, or use artificial tears.
Schedule regular eye exams: Routine eye exams are essential for everyone, including children. They help maintain your vision and detect issues early, such as glaucoma, which may not show symptoms initially but are more accessible to treat when caught early.

Eye issues in the US and Texas
According to estimates published by the National Eye Institute (NEI) and the Centers for Disease Control and Prevention (CDC), over 4 million Americans over 40 are blind or suffer from reduced vision. In 2020, the number of Americans with reduced or no vision rose to 6 million. Moreover, according to the NEI, the most common eye diseases in Americans over 40 are age-related macular degeneration, cataracts, diabetic-related eye disease, and glaucoma.
According to the CDC, over 650,000 people in Texas report severe vision difficulties and blindness, even with glasses. People with vision loss are also more prone to diabetes (24%), arthritis (29%), and mobility issues (33%). 49% of individuals over the age of 65 having severe vision impairment reported having a fall in the previous year.
