When it’s time to schedule an eye appointment, many patients face a common question: “Should I see an ophthalmologist or an optometrist?” Understanding the differences between these eye care professionals — and knowing when you need each one — can help you get the right care for your vision needs.
Whether you need a routine eye exam, treatment for an eye condition, or vision correction surgery, Berkeley Eye Center’s network of ophthalmologists, optometrists, and opticians work together to provide comprehensive care at 25+ convenient locations across Texas.
Understanding Eye Care Professionals: The Basics
The world of eye care includes three primary types of professionals, each with distinct training, expertise, and roles in protecting your vision. Let’s break down what each does and how they work together to care for your eyes.
What Is an Optometrist?
An optometrist is a primary eye care professional who provides essential vision services for patients of all ages. Optometrists hold a Doctor of Optometry (OD) degree and are licensed healthcare professionals specializing in vision care.
Education and Training
Optometrists complete:
- 3-4 years of undergraduate college (pre-optometry coursework)
- 4 years of optometry school earning a Doctor of Optometry (OD) degree
- State licensing examinations to practice optometry
- Continuing education requirements to maintain licensure and stay current with evolving eye care standards
What Optometrists Do
Optometrists provide comprehensive primary vision care, including:
- Comprehensive eye exams and vision testing
- Prescribing corrective lenses (eyeglasses and contact lenses)
- Diagnosing vision problems like nearsightedness, farsightedness, and astigmatism
- Detecting eye diseases such as glaucoma, cataracts, diabetic retinopathy, and macular degeneration
- Prescribing medications for certain eye conditions and diseases
- Managing eye conditions including dry eye, conjunctivitis (pink eye), and eye allergies
- Providing pre- and post-operative care for patients undergoing eye surgery
- Vision therapy for certain eye coordination and focusing problems
- Pediatric vision care including screening for childhood eye conditions
What Optometrists Typically Don’t Do
While optometrists provide extensive eye care, they are generally not trained or licensed to:
- Perform eye surgery (including LASIK, cataract surgery, or retinal procedures)
- Treat complex or surgical eye diseases
- Perform certain invasive procedures
However, optometrists play a crucial collaborative role in surgical care, providing pre-operative evaluations and post-operative monitoring for surgical patients.
What Is an Ophthalmologist?
An ophthalmologist is a medical doctor (MD) or osteopathic doctor (DO) who specializes in comprehensive eye and vision care, including medical treatment and surgery. Ophthalmologists are physicians who can diagnose and treat all eye conditions, prescribe medications, and perform eye surgery.
Education and Training
Ophthalmologists complete extensive medical training:
- 4 years of undergraduate college
- 4 years of medical school (earning an MD or DO degree)
- 1 year of internship (general medical training)
- 3+ years of ophthalmology residency (specialized hospital-based training in eye and vision care)
- Optional fellowship training (1-2 additional years) for subspecialties like retina, glaucoma, cornea, oculoplastics, or pediatric ophthalmology
This medical training totals 12-14 years after high school, making ophthalmologists among the most extensively trained medical professionals.
What Ophthalmologists Do
Ophthalmologists provide the full spectrum of eye care, including everything optometrists do, plus:
- All services optometrists provide (exams, prescriptions, disease detection)
- Medical treatment of complex eye diseases, including advanced glaucoma, macular degeneration, and diabetic retinopathy
- Eye surgery, including:
- Cataract surgery
- LASIK and PRK (laser vision correction)
- Glaucoma surgery
- Retinal surgery
- Corneal transplants
- Oculoplastic surgery (eyelid and orbital procedures)
- Emergency eye trauma surgery
- Treating eye emergencies such as retinal detachment, severe eye injuries, or sudden vision loss
- Managing systemic diseases that affect the eyes (diabetes, autoimmune conditions, neurological disorders)
- Subspecialty care for complex conditions requiring advanced expertise
Ophthalmology Subspecialties
Many ophthalmologists pursue fellowship training in subspecialties:
- Retina Specialists: Treat diseases of the retina and vitreous (macular degeneration, diabetic retinopathy, retinal detachment)
- Glaucoma Specialists: Manage complex glaucoma cases and perform specialized glaucoma surgeries
- Cornea Specialists: Treat corneal diseases and perform corneal transplants
- Pediatric Ophthalmologists: Specialize in children’s eye conditions and eye muscle disorders
- Oculoplastic Surgeons: Perform eyelid, orbital, and facial reconstructive surgery
- Neuro-Ophthalmologists: Treat vision problems related to the nervous system
What Is an Optician?
While opticians are not eye doctors, they’re an essential part of your vision care team. An optician is a trained technician who specializes in the fitting and dispensing of eyeglasses and contact lenses.
What Opticians Do
- Interpret prescriptions written by optometrists or ophthalmologists
- Help patients select eyeglass frames that fit properly and suit their needs
- Take facial measurements to ensure proper lens positioning
- Order and verify eyeglass lenses meet prescription specifications
- Adjust and repair eyeglasses for optimal fit and comfort
- Fit contact lenses and provide instruction on insertion, removal, and care
- Recommend lens options (progressive, bifocal, photochromic, anti-reflective coatings)
What Opticians Don’t Do
Opticians do not:
- Perform eye exams
- Diagnose vision problems or eye diseases
- Write prescriptions for eyeglasses or contact lenses
- Treat eye conditions or prescribe medications
Opticians work from prescriptions provided by optometrists or ophthalmologists to ensure you receive eyewear that precisely matches your vision correction needs.

Which Eye Doctor Do You Need to See?
The right eye care professional depends on your specific vision needs and eye health status. Here’s a guide to help you decide:
See an Optometrist For:
- Routine comprehensive eye exams (annual or biennial checkups)
- Updating your eyeglass or contact lens prescription
- Managing common eye conditions like dry eye or mild allergies
- Initial evaluation of vision changes or eye discomfort
- Contact lens fittings and follow-up care
- Vision problems like nearsightedness, farsightedness, or astigmatism
- Children’s vision screenings and pediatric eye care
- Pre- and post-operative care for LASIK or cataract surgery patients
- Management of chronic conditions like glaucoma or diabetic retinopathy (in collaboration with ophthalmologists)
For patients with generally healthy eyes who need routine vision care, both optometrists and ophthalmologists are qualified to provide excellent care. The choice often comes down to personal preference, availability, and convenience.
See an Ophthalmologist For:
- Eye diseases requiring medical treatment, such as:
- Cataracts
- Glaucoma
- Macular degeneration
- Diabetic retinopathy
- Retinal conditions
- Vision correction surgery (LASIK, EVO, RLE, PRK, cataract surgery)
- Eye emergencies including:
- Sudden vision loss
- Eye trauma or injury
- Retinal detachment symptoms (flashes, floaters, curtain over vision)
- Severe eye pain or infection
- Complex or advanced eye conditions requiring surgical intervention
- Second opinions on surgical recommendations
- Chronic eye diseases requiring subspecialty expertise
- Systemic diseases affecting the eyes (diabetes, autoimmune conditions)
The Collaborative Approach
In many cases, your optometrist and ophthalmologist work together as a team:
- Initial Detection: Your optometrist may detect an eye disease during a routine exam
- Specialist Referral: The optometrist refers you to an ophthalmologist for specialized treatment
- Surgical Care: The ophthalmologist performs necessary procedures or surgery
- Ongoing Management: Your optometrist provides follow-up care and monitoring
- Communication: Both doctors consult to ensure comprehensive, coordinated care
This collaborative model ensures you receive both accessible primary eye care and specialized treatment when needed.

Frequently Asked Questions About Ophthalmologists vs. Optometrists
Can an optometrist diagnose glaucoma or cataracts?
Yes, optometrists are trained to detect and diagnose eye diseases including glaucoma, cataracts, macular degeneration, and diabetic retinopathy during comprehensive eye exams. If treatment or surgery is needed, your optometrist will refer you to an ophthalmologist while often continuing to provide monitoring and co-management care.
Do I need a referral to see an ophthalmologist?
In most cases, no referral is required to see an ophthalmologist. However, your insurance plan may have specific referral requirements, so it’s best to check with your insurance provider. Many patients are referred by their optometrist when specialized care is needed.
Can ophthalmologists prescribe glasses and contact lenses?
Yes, ophthalmologists are fully qualified to perform eye exams and prescribe corrective lenses just like optometrists. However, many ophthalmologists focus primarily on medical and surgical eye care, while optometrists often specialize more in primary vision care and contact lens fittings.
Is an ophthalmologist’s exam more thorough than an optometrist’s?
Both optometrists and ophthalmologists perform comprehensive eye exams that include vision testing, eye health evaluation, and disease screening. The thoroughness depends on the individual doctor and your specific needs rather than the type of degree. For routine healthy eyes, both provide equally comprehensive exams.
Who should perform my LASIK evaluation?
LASIK surgery must be performed by an ophthalmologist. However, many LASIK surgeons work closely with optometrists who perform pre-operative evaluations to determine candidacy and provide post-operative care. At Berkeley Eye Center, our ophthalmologists and optometrists collaborate throughout the entire LASIK process.
Can an optometrist treat eye infections?
Yes, optometrists can diagnose and prescribe medications for many eye infections including bacterial conjunctivitis (pink eye), certain viral infections, and other common conditions. For severe infections or cases requiring surgical intervention, they’ll refer you to an ophthalmologist.
What if I’m not sure which doctor I need?
When in doubt, start with a comprehensive eye exam. If you have an established optometrist, they can evaluate your condition and refer you to an ophthalmologist if specialized care is needed. At Berkeley Eye Center, our integrated team ensures you’re connected with the right specialist for your needs.
Do ophthalmologists cost more than optometrists?
Costs vary depending on the services provided rather than the type of doctor. Routine eye exams typically cost similarly whether performed by an optometrist or ophthalmologist. Insurance coverage often determines your out-of-pocket costs. Specialized services or surgery will have different pricing regardless of who diagnosed the condition.
