Who is an optometrist?
Earlier known as ophthalmic opticians, optometrists are eye specialists who can diagnose and treat diseases and disorders that affect the eyes. They can examine the eyes and detect issues ranging from vision problems to macular degeneration to glaucoma. Since many eye problems are ocular manifestations of systemic diseases, optometrists can also detect problems in other body parts.Â
A comprehensive eye test by an optometrist can detect over 270 severe health conditions, including diabetes, brain tumors, high blood pressure, sexually transmitted diseases, cancers, autoimmune diseases, aneurysms, and other illnesses. Optometrists can also prescribe spectacles, contact lenses, and medications and perform specific surgical procedures.
Optometrists generally have private clinical practices or work in public health centers, hospitals, and teaching institutions. Some even prefer to be part of research projects.
What kind of education and training do optometrists receive?
One must complete their graduation and join an optometry school to become an optometrist. They can join any of the 23 accredited optometry schools in the country. To gain admission, one must clear an admission test authorized by the Association of Schools and Colleges of Optometry. In an optometry school, students study the different aspects of optometry for the first two years. The following two years comprise clinical work, after which they receive the Doctor of Optometry degree.
If optometrists want to specialize further, they can join a residency program. Optometry subspecialties include low-vision therapy, neuro-optometry, and sports vision.
What is the difference between an optometrist, an ophthalmologist, and an optician?
If you've searched for an eye doctor near you, you know there are various eye specialists: optometrists, ophthalmologists, and opticians. They all specialize in eye care and often collaborate, offering the best vision care and treatment options.
However, understanding the difference between optometrist, ophthalmologist, and optician is crucial as it helps you consult the best eye doctor near you according to your needs. So, here are the key differences between the three:
- Optometrists (ODs): After earning their bachelor's degree, optometrists complete a 4-year postgraduate program to obtain a Doctor of Optometry degree. Some may choose to undergo additional clinical training or specialized fellowships. Their primary focus is regular vision care, including eye exams and vision tests. Optometrists prescribe eyeglasses and contact lenses and monitor medically related eye conditions (e.g., diabetes). They also manage conditions like dry eye and glaucoma and offer low-vision aids and vision therapy.
- Ophthalmologist: Ophthalmologists undergo extensive education and training. This includes completing medical school, a 1-year internship, and a 3-year residency, followed by a 1 to 2-year fellowship. They provide vision services and medical eye care for conditions like glaucoma and iritis. Ophthalmologists provide surgical eye care for trauma and cataracts and diagnose and treat eye conditions related to diseases like diabetes or arthritis. They can also offer plastic surgery for eyelid and wrinkle concerns.
- Opticians: Opticians aren't eye doctors and can't perform eye exams. They have a one—or two-year degree, certificate, or diploma. Their tasks include filling the prescription given by the eye doctor, checking lens prescriptions, providing, adjusting, and repairing glasses and contact lenses, and taking facial measurements. Opticians assist you in choosing suitable lenses and frames. They also order and inspect products such as contacts and eyeglass lenses.
What can you expect on your first visit to an optometrist near you?
When you visit an optometrist, they will check documents related to your medical history for any existing eye problems. They will speak to you and ask if there are any symptoms you are aware of regarding eye disorders. They will then check for refractive errors and conduct a visual acuity test to check your eyesight. After this, they will recommend contact lenses, spectacles, or other treatments if required.
The optometrist will also check for eye disorders such as macular degeneration, glaucoma, and other conditions that could affect the eyes, such as high blood pressure and diabetes. Optometrists may prescribe topical or oral antibiotics, some scheduled analgesics, antihistamines, or non-steroidal anti-inflammatory drugs.
When should one visit an optometrist?
One should visit an optometrist to maintain eye health and optimal vision. In addition, a comprehensive eye examination can diagnose asymptomatic ocular illness and systemic conditions. Since severe disorders such as glaucoma and retinopathy don't have symptoms, it is difficult to detect these conditions early. If left untreated for a long time, both of these diseases can result in vision loss. However, visiting an optometrist can help begin treatment earlier and save a patient's eyesight because these specialists detect such conditions.
If you wear spectacles or lenses, you need to check your eyesight regularly and keep your prescription updated by visiting an optometrist. If you feel any strain on your eyes or experience frequent headaches, it might be a sign that you are using glasses with the wrong or outdated prescription.
What is glaucoma, and how serious is it?
Glaucoma is a vision-threatening disease. However, it can be treated if it is detected early by an optometrist. The symptoms of glaucoma include blurry vision, vomiting, severe headaches, and eye pain. Glaucoma is caused by increased intraocular pressure damaging the optic nerve. If the optometrist detects the disorder early, they might recommend preventive options, such as wearing UV-coated sunglasses to protect against eye injury.
What conditions do optometrists treat?
Besides glaucoma, optometrists treat several eye conditions. Some of these are:
- Astigmatism: People with astigmatism have an eye shape that is more curved than it should be. Its symptoms include fatigue, headache, eye strain, and halos around lights. Astigmatism is a type of refractive error, and its symptoms include fatigue, headache, eye strain, and noticing halos around lights.
Astigmatism has two types: corneal (higher curvature in the cornea) and lenticular (higher curvature in the lens). While eyeglasses and contact lenses can improve vision, they cannot change the eye shape. Vision correction surgery (LASIK eye surgery and PRK eye surgery) can help.
- Myopia: Myopia, the medical name for nearsightedness, is a common eye focus disorder. Nearsighted people can see nearby objects clearly but find it difficult to see objects farther away.
There are two types of myopia: simple and pathologic (earlier known as degenerative myopia). Optometrists can suggest eyeglasses, contact lenses, or surgery to help manage myopia.
- Hyperopia, the medical name for farsightedness, is a common eye condition that causes blurry close-up vision. Depending on the degree of eye curvature, hyperopia can be low, moderate, or high.Â
People with hyperopia have difficulty focusing their vision on close-up objects despite finding it easy to see objects at least 6 meters away. Other symptoms include eye strain, dull eye pain, and headache. Eyeglasses, contact lenses, and surgery can help fix this condition.
- Diplopia: Diplopia refers to double vision. People with this condition see two images of a single object. While it is typically a temporary concern, it can also signify more serious health conditions, such as proptosis, keratoconus, and vertigo.Â
Diplopia can be monocular or binocular and horizontal or vertical. Its symptoms include nausea, headache, dizziness, and pain when moving the eyes.
How often should you visit an optometrist near you?
Regular eye exams and check-ups are key to keeping your vision sharp and catching potential issues early. The frequency of eye check-ups depends on factors like age and overall eye health. For kids, it's a good idea to have their eyes examined by a pediatrician before they start school, with follow-ups every year - or sooner if any concerns pop up.
For adults aged 18 to 65, an eye exam every one to two years is generally recommended. Once you hit 65, it's best to get checked every two to four years. However, many experts suggest annual exams starting at 55 to monitor age-related changes.
If you wear prescribed glasses or contact lenses or have any existing eye conditions, you should visit your eye doctor more often. The best way to know for sure is to book an appointment with an optometrist near you to figure out a schedule that works for you.
Worsening of vision
Does your vision get worse with age? Not exactly, but your risk for eye-related conditions and diseases does increase over time.
After the age of 50, you're more likely to develop conditions such as:
- Age-related macular degeneration
- Cataracts
- Glaucoma
- Diabetic retinopathy
Taking care of your eyes goes beyond eating a balanced diet and staying active. Here are a few extra steps you can take to protect your vision:
- Wear sunglasses and a brimmed hat when you're out in bright sunlight.
- Use protective eyewear when playing sports, working with power tools, or handling chemicals.
Adopting these habits can help maintain clear vision and reduce the risk of eye problems as you age.

Statistics on optometrists and chronic conditions in Massachusetts
Optometrists can detect several chronic conditions by doing a comprehensive eye test. According to the U.S. Bureau of Labor Statistics, as of May 2023, there were 970 optometrists in Massachusetts.
Patients who have diabetes are vulnerable to a range of eye problems. Over time, a high blood sugar level affects the blood vessels in one's eyes. To ensure that diabetes does not cause lasting damage to one's eyes, one must visit an optometrist regularly. According to America's Health Rankings, about 810.5% of the adult population in Massachusetts was diagnosed with diabetes in 2022. This excluded prediabetes and gestational diabetes. The condition's incidence was slightly higher in men (12.0%) than in women (9.1%).Â
Hypertension, or high blood pressure, often damages the blood vessels in the retina, a condition known as hypertensive retinopathy. Another report by America’s Health Rankings stated that about 29.9% of the adult population in Massachusetts was diagnosed with high blood pressure in 2021. The incidence of hypertension also increased with age, with 59.0% of those 65 and above suffering from the condition.
