Who are optometrists?
An optometrist, sometimes known as a doctor of optometry, is a trained health practitioner who examines, diagnoses, treats and prevents diseases and disorders of the eyes. A doctor of optometry should be your first choice for eye care because they specialize in managing all aspects of your eye health.
The following are some issues addressed in optometry:
- Body and eye anatomy
- Community health
- Contact lenses
- Genetics
- Elderly vision
- Environmental awareness
- Illumination and light
- Visual impairment
- Neurophysiology
- Optics (geometric, physiological, and ophthalmic)
- Children's vision
- Diseases of the body and eyes
- Pharmaceutical science (body and eye)
- Physiology
A typical vision and eye health examination can include the following:
- Analysis of internal and exterior eye health
- The understanding of vision (eye chart)
- Examination of pupil reflexes
- Motility, alignment, and focusing
- Stress testing
- Testing of depth perception
- Color vision evaluation
With technology advancements, optometric therapy is continually changing and improving.
Some common treatments by the optometrist near you include:
- Prescribing spectacles and contact lenses
- Medical treatment such as eye drops, gels, and ointments
- Minor surgical treatments such as the removal of foreign materials (e.g., metal), the insertion of tear duct plugs for dry eyes, and the flushing of clogged tear ducts
- Correcting or enhancing binocular vision (how the eyes operate together) and focusing abnormalities, including amblyopia and double vision.
- Low vision treatment
- Referral to a healthcare provider, like family doctors and eye surgeons
What kind of education and training do optometrists receive?
In the U.S., most optometry schools offer postgraduate programs requiring a bachelor's degree for admission. However, some schools may accept applicants without a degree, provided they have completed prerequisite science and math courses. To gain entry into optometry school, you typically need strong scores on tests such as the Optometry Admission Test (OAT), Medical College Admission Test (MCAT), Graduate Record Examinations (GRE), or Dental Admission Test (DAT).
Optometry programs typically last four years and cover a variety of subjects related to eye care and practice management, including:
- Anatomy and physiology of the eye, brain, and nervous system
- Eye diseases and eye health maintenance
- Patient examination and diagnosis
- Pharmacology, including prescribing eye-related and systemic medications
- Optics, focusing on the physics of vision and correction
- Materials for contact lenses and glasses
- Clinical management
After completing optometry school, you’ll earn a Doctor of Optometry (OD) degree. You must then pass the National Board of Examiners in Optometry (NBEO) exam to apply for a state license. Once licensed, you can pursue additional clinical training or specialize in areas like specific eye conditions or patient populations through a fellowship.
The role of optometrists
Optometrists work with patients with vision problems to find remedies. Patients first have general eye examinations, during which the optometrist takes a medical history of the patient's eye problems. After a refractive assessment, the optometrist will perform a visual acuity test to determine the eyesight. For adequate vision, optometrists prescribe spectacles or contact lenses with the calculated refractive status of the eyes. Optometrists undertake the following tasks in addition to vision testing.
- Detection of eye disease: Optometrists use the ophthalmoscope to diagnose eye disorders, such as glaucoma and macular degeneration, and conditions that affect ocular functions, such as diabetes and hypertension. If the anomalies in the detection remain, the optometrist might refer the patient for additional specific testing.
- Prescription of medications for diseases: Optometrists are licensed to administer topical antibiotics, antihistamines, nonsteroidal anti-inflammatory drugs, and scheduled analgesics to treat ocular illnesses and glaucoma. Optometrists can only prescribe the oral form of these medications.
- Contact lens professionals: Optometrists who handle contact lenses for individuals with irregular corneal shapes can also prescribe toric and varifocal lenses.
- Outpatient primary eye care: An optometrist checks the patient's eyesight, prescribes corrective lenses, and is an expert in handling the equipment required to assess the patient's eyes. Optometrists can also treat patients with irreversible vision loss and teach patients how to perform regular visual workouts to improve their vision.
- Binocular vision treatment: Optometrists personalize vision therapy for individuals with binocular abnormalities.
- Patient counseling and review: Optometrists counsel cataract patients through pre- or post-surgical procedures and on the proper use of contact lenses. They also check the patient's previous medical records to determine their visual state.
- Collaborate with other medical professionals: An integrated eye care paradigm allows optometrists and ophthalmologists to collaborate to improve patient care.
- Research and training: Optometrists participate in studies on several vision problems caused by neurological illnesses or other causes.
Difference between optometrists and ophthalmologists
Some of the basic differences between ophthalmologists and optometrists are:
- Ophthalmologist: An ophthalmologist is a board-certified medical doctor specializing in eye and vision care. They attend graduate medical school and earn a medical degree. They are qualified and trained to detect and treat all eye conditions or diseases. They can even prescribe medications or corrective eyeglasses and perform eye surgeries. Ophthalmologists actively participate in scientific research on the cause and treatment of vision disorders and eye diseases. Ophthalmologists are the best eye professionals for severe eye conditions.
- Optometrist: Optometrists primarily focus on vision defects or refractive errors in patients. They attend graduate optometry school and obtain an optometry degree. Optometrists can test and correct eyesight. They can even diagnose, treat, and manage vision impairment issues. However, they cannot detect all eye disorders or perform eye surgeries. Optometrists can detect eye abnormalities early and refer you to an ophthalmologist for better treatment. They are the best eye professionals to guide you on best practices for using contact lenses.
What is a comprehensive eye exam?
As implied by the name, a comprehensive eye exam consists of vision tests and a checkup of the overall health of ocular tissues. Optometrists conduct this examination depending on the individual patient's symptoms. By getting regular comprehensive eye exams with a medically recognized optometrist, one can identify vision problems such as glaucoma and other chronic illnesses such as diabetes, hypertension, tumors, and aneurysms promptly.
While vision screenings check your vision health, they only focus on certain parts of the eyes. Whereas comprehensive eye exams can detect and check for major issues, making them more crucial for maintaining both ocular and general health.
Tips for ocular care
The first step to good vision care involves regular comprehensive dilated eye examinations with a licensed optometrist. Knowing your family's history of eye health and sharing it with the optometrist helps the eye care provider protect your visual and general health before problems arise or worsen. Healthy lifestyle changes have long-term effects on both ocular and general health.
Significant changes include:
- Following a healthy diet rich in eye-healthy foods like carrots, green leafy vegetables, and fish with omega-3 fatty acids
- Including a moderate exercise regimen
- Monitoring weight and working on keeping it within a healthy range
- People working extensively on screens should regularly rest their eyes to prevent them from getting overstrained.
- Regular disinfection of contact lenses aids in keeping the eyes healthy and strong.
Smoking is very harmful to the eyes and can lead to severe problems such as cataracts, optic nerve damage, and age-related macular degeneration. These medical issues increase the chances of going blind, so quitting cigarettes is helpful. Covering your eyes with protective shades during sports and in the sun helps protect them from the sun's harmful UV rays.
What nutrients can help optimize eye health?
Specific nutrients help improve and maintain eye health. Including these in your diet can go a long way toward ensuring good vision well into old age.
- Vitamin A: Vitamin A is vital to maintain the photoreceptors or light-sensing cells present in the eye. Severe vitamin A deficiency is the top cause of blindness worldwide. Foods like dairy products, egg yolks, and liver are rich in vitamin A
- Omega-3 fatty acids: These fatty acids are essential for the optimal development of eye vision in infants and children. They improve tear production, reduce inflammation, and reinforce the oily outer layer of the eyes. Omega-3 fatty acid-rich foods like salmon and tuna should be a regular part of diets to support eye health.
- Zinc: Zinc is a crucial nutrient that brings vitamin A from the liver to the retina. Zinc deficiency can cause impaired vision conditions like cloudy cataracts and night blindness. Red meat, shellfish, seeds, nuts, and oysters are rich sources of zinc.
- Lutein and zeaxanthin: Higher quantities of lutein and zeaxanthin in the body significantly reduce the chances of developing new cataracts. Dark green leafy vegetables, broccoli, peas, corn, tangerines, and persimmons are rich in lutein and zeaxanthin.
- Vitamin E: Vitamin E is a crucial nutrient that protects the cells from free radicals or unstable molecules that break down healthy tissues in the eye area. Foods like wheat germ, nuts, and sweet potatoes contain vitamin E; you must include them in your daily diet.
- Vitamin C: Vitamin C can help lower the risk of visual acuity loss and age-related macular degeneration when consumed with other essential nutrients. Foods like strawberries, grapefruit, tomatoes, papaya, and green pepper are rich in vitamin C.
Why and when should you visit an optometrist?
Maintaining the health of your eyes is a vital part of your overall well-being. It’s important to ask your optometrist how often you should get your eyes checked, though a general guideline suggests that children should have their first eye exam in the first year of life, followed by exams every 1-2 years. Adults aged 18-55 should have an eye exam every 1-2 years, while those over 55 should check their eyes annually.
More frequent exams may be necessary if you use glasses, contact lenses, or other visual aids. You should also see an optometrist if you have a chronic condition like diabetes, which increases the risk of eye disease, have a family history of vision problems, or take prescription medications that affect your eyes.
Additionally, you must visit your optometrist for evaluation if you experience symptoms such as worsening vision, eye redness or irritation, floaters (specks that float across your vision), and flashes of light. This also applies if you experience light sensitivity, blurry or double vision, halos around lights, or persistent eye pain.

Vision issues in Baltimore
A survey conducted from 2016 to 2019 and published in ARVO Journals, in Baltimore City public schools, one-third of children failed vision screening, with higher failure rates in classes where Maryland law does not require vision screening. The experts referred only 3% of pupils to the necessary spectacles. The common reason for screening failure was poor visual acuity; the experts corrected most of these kids to 20/25 or better with glasses.
