A medical doctor specializing in eye and vision care. They are licensed to provide comprehensive eye exams, diagnose and treat all eye diseases, perform eye surgery, like cataract or LASIK, and prescribe glasses and contact lenses. For individuals with complex medical conditions or those requiring surgery, an ophthalmologist offers the deepest level of care.
A healthcare professional who provides primary vision care, including comprehensive eye exams, vision testing, prescribing and dispensing corrective lenses, and diagnosing certain eye conditions like dry eye and prescribing some medications. They refer patients to ophthalmologists for complex cases or surgical needs.
Family History: History of glaucoma, macular degeneration, or other eye conditions in relatives.
Medication Review: Systemic medications that may have ocular side effects.
Symptom Check: Discussing any current changes in vision, headaches, eye strain, or discomfort.
This test measures the sharpness and clarity of your vision, usually using the Snellen chart, the familiar chart with letters of decreasing size. The result is expressed as a fraction, such as 20/20 (normal vision) or 20/40.
This process determines the precise lens power needed to correct refractive errors. The doctor uses a phoropter to present a series of lens choices, asking, “Which is clearer, one or two?” to fine-tune your prescription for glasses or contacts.
This test measures the intraocular pressure (IOP), a primary screening tool for glaucoma. The most common method involves applying special eye drops, followed by a small burst of air or a touch of a specialized instrument to the eye’s surface.
The slit-lamp is a powerful, low-power microscope that allows the ophthalmologist to examine the anterior segment of the eye in detail, including the:
Cornea
Lens
Iris
Eyelids
Tear film
Dilating eye drops temporarily widen the pupil, giving the doctor a clear, magnified view of the posterior segment of the eye, which includes the:
Retina: The light-sensitive tissue lining the back of the eye.
Optic Nerve: The nerve that transmits visual information to the brain.
Retinal Blood Vessels: Necessary for detecting signs of systemic disease like hypertension and diabetes.
Dilating eye drops temporarily widen the pupil, giving the doctor a clear, magnified view of the posterior segment of the eye, which includes the:
Optical Coherence Tomography (OCT): Provides high-resolution cross-sectional images of the retina and optic nerve, for monitoring glaucoma and macular degeneration.
Corneal Mapping (Topography): Creates a 3D map of the cornea's surface curvature, necessary for contact lens fitting and detecting conditions like keratoconus.
Retinal Photography: Takes high-definition photos of the back of the eye to document the current state of the retina and optic nerve for future comparison.
Nearsightedness: Difficulty seeing distant objects clearly.
Farsightedness: Difficulty seeing close objects clearly.
Astigmatism: Blurred vision at any distance due to an irregularly shaped cornea.
Presbyopia: Age-related loss of near focusing ability, usually starting after age 40.
Common in the dry LA climate and exacerbated by prolonged screen time, this condition is assessed by the exam, which evaluates the quantity and quality of the tear film.
Often called the “silent thief of sight,” this group of diseases damages the optic nerve, typically due to elevated eye pressure. It often presents without symptoms in the early stages, making routine tonometry and optic nerve evaluation essential for early treatment and the prevention of irreversible vision loss.
A clouding of the natural lens of the eye that causes blurry vision and glare. It is easily detected during the slit-lamp exam and is highly treatable with surgery.
Damage to the macula, the central part of the retina, leads to loss of central vision. Early signs are visible through a dilated exam and OCT.
Damage to the retinal blood vessels caused by high blood sugar. It is the leading cause of blindness in working-age adults, yet it is preventable with yearly dilated exams and proper medical management.
Potentially sight-threatening emergencies can be detected during the dilated examination, enabling immediate treatment.
Keratoconus is a condition where the cornea thins and bulges into a cone shape, which is detected via corneal mapping.
The eye is the only place in the body where a doctor can directly view the live, small blood vessels and nerves. Changes can indicate:
Importance: Early detection is important for learning, which is up to 80% dependent on vision. Uncorrected problems such as lazy eye or an eye turn can lead to permanent vision loss if not treated early.
Focus: Checking for alignment, focusing ability, and any refractive errors that can impact school performance.
Focus: Monitoring stable or changing refractive errors, addressing digital eye strain from prolonged screen use, and checking for early signs of dry eye.
Focus: Managing presbyopia, the need for reading glasses, and increased screening for glaucoma and cataracts, which typically begin to develop around this age.
Focus: More frequent monitoring for age-related degenerative conditions like macular degeneration and ensuring good vision to mitigate fall-risk issues.

Heavy UV exposure in Los Angeles necessitates regular checks for cataracts and retinal damage. High allergen counts can contribute to chronic ocular surface issues like dry eye and conjunctivitis.
Contact lens wearers require an annual comprehensive exam plus a dedicated contact lens fitting appointment. These visits include additional measurements of the corneal curvature and a detailed slit-lamp evaluation of the cornea to check for:
Ensure that the physician is board-certified by the American Board of Ophthalmology (ABO).
If you have a specific condition, look for fellowship-trained specialists.
The presence of tools, such as OCT and retinal photography, indicates a commitment to advanced, modern diagnostics.
A well-established LA practice should have extensive experience managing conditions like advanced cataracts, high-risk glaucoma, and diabetic retinopathy.
Confirm the provider accepts your specific medical insurance and/or vision plan to minimize out-of-pocket costs.
Typically cover routine vision exams for a low copay, focusing on determining a prescription for glasses/contacts and basic eye health screening.
Covers the cost of a medical eye exam when there is a diagnosis, symptom, or treatment of a disease.
If your exam involves the diagnosis or management of a medical condition, it will likely be billed to your medical insurance. Be sure to clarify with the office what is covered under your plan, as specialized tests like OCT or contact lens fittings may incur additional costs. Without insurance, the cost of a routine comprehensive eye exam in Los Angeles generally ranges from $75 to $250, with specialized testing adding $50–$100 per test.
A list of all current medications, including doses, and all current corrective eyewear.
Dilation typically lasts for 4–6 hours, causing light sensitivity and blurred near vision.
You will likely need a driver if your pupils are dilated, as driving immediately afterward can be difficult and unsafe.
Prepare a list of questions for your ophthalmologist about your vision goals, specific concerns, or potential treatment options.
A routine, comprehensive eye exam is the best step you can take to protect your vision for the long term. By choosing a
