Getting an eye exam starts with choosing the right provider, scheduling an appointment, and knowing what to expect when you arrive. For most adults without eye problems, the process is straightforward and takes about an hour. If you’ve never had a comprehensive exam or it’s been a while, here’s everything you need to know.
Decide Which Type of Eye Doctor You Need
There are two main types of eye doctors, and either one can perform a comprehensive eye exam. An optometrist holds a doctor of optometry (OD) degree after four years of optometry school. They perform eye exams, prescribe glasses and contacts, detect eye abnormalities, and in most states prescribe medications for certain eye diseases. For the majority of people who need a routine checkup or an updated prescription, an optometrist is the right choice.
An ophthalmologist is a medical doctor (MD or DO) with 12 to 14 years of total training, including medical school and surgical residency. They diagnose and treat all eye diseases, perform eye surgery, and can also prescribe corrective lenses. If you have a known eye condition like glaucoma, cataracts, or diabetic eye disease, or if you need surgery, an ophthalmologist is the better fit. They can also sometimes spot signs of systemic health problems unrelated to your eyes.
A third option, an optician, fills prescriptions for glasses and contacts but does not perform exams or diagnose conditions.
How Often You Actually Need an Exam
The schedule depends on your age and risk factors. Children should have their eyes assessed during newborn checkups and at every routine pediatric visit afterward. School-age kids need vision and alignment checks every one to two years, either at a doctor’s office or through school screenings.
Adults with no risk factors should get a baseline comprehensive exam at age 40. From there:
- Ages 40 to 54: every 2 to 4 years
- Ages 55 to 64: every 1 to 3 years
- Age 65 and older: every 1 to 2 years
If you have risk factors, the timeline tightens. People with type 2 diabetes should have an eye exam at the time of diagnosis and at least yearly after that. Those with type 1 diabetes need an exam five years after disease onset, then annually. Black adults, who face higher glaucoma risk, should consider exams every two to four years before age 40, with increasing frequency after that. If you wear contacts or glasses, your prescribing doctor will typically want to see you every year or two regardless of age.
How to Schedule and Prepare
You can book an appointment by calling a local optometry office or ophthalmology practice directly. Many offices also accept online booking. If you have vision insurance, check your plan’s provider directory first to confirm coverage. Without insurance, you can still call any practice and ask about self-pay pricing.
Before your appointment, gather a few things. Bring your current glasses or contacts (including the brand name and prescription if you have it). Make a list of all medications you take, including over-the-counter supplements. Write down any vision symptoms you’ve noticed, like difficulty reading at night, headaches, or floaters. Your doctor will also ask about your family’s medical history, particularly any relatives with glaucoma, macular degeneration, or diabetes, so it helps to know this in advance.
What Happens During the Exam
A comprehensive eye exam includes several distinct tests, most of which are painless and take just a few minutes each. The whole visit typically runs 30 to 60 minutes, longer if your eyes are dilated.
The exam usually starts with a visual acuity test using an eye chart to measure how well you see at various distances. Next comes refraction, where the doctor places different lenses in front of your eyes using a device called a phoropter. You’ll be asked “which is clearer, one or two?” repeatedly as they narrow down the exact lens power you’d need to correct nearsightedness, farsightedness, or astigmatism.
Beyond your prescription, the doctor checks several aspects of eye health that you can’t test on your own. They’ll examine how well your eyes move and whether your eye muscles are working together. A peripheral vision test measures how much you can see to the sides while looking straight ahead. An eye pressure test checks whether pressure inside your eye is in a healthy range, which is the primary screening tool for glaucoma. The doctor will also examine the front of your eye for damage and inspect the retina and optic nerve at the back of your eye for signs of disease.
What to Expect From Dilation
For many exams, the doctor will dilate your pupils using eye drops. This widens the dark opening in the center of your eye, allowing more light in so the doctor can get a detailed look at your retina and optic nerve. The drops take about 15 to 30 minutes to fully work.
Dilation generally lasts between 4 and 24 hours. During that time, you’ll experience blurred vision (especially up close), sensitivity to bright light, and difficulty focusing on nearby objects. Bring sunglasses to your appointment if you have them. Some people feel comfortable driving afterward, but if you’ve never been dilated before, it’s smart to arrange a ride home. Your doctor may recommend avoiding driving until the effects wear off.
Costs Without Insurance
A first-visit comprehensive eye exam typically costs $171 to $200 without insurance. Return visits for established patients average around $128. Prices vary by location and provider, and some retail chains and warehouse clubs offer exams at the lower end of that range. If you need glasses or contacts, that’s an additional cost on top of the exam fee.
If cost is a barrier, several national programs offer free or reduced-cost care. EyeCare America provides free comprehensive exams and up to one year of follow-up care for adults 18 and older. VSP Eyes of Hope covers no-cost exams and glasses for uninsured people with limited income. Lions Clubs International helps pay for eye care through local chapters and may also provide glasses. For children, the InfantSEE program offers free assessments for babies 6 to 12 months old, and All Children See connects kids who failed a vision screening with doctors who can do a full exam (available in select states). The nonprofit Prevent Blindness maintains a comprehensive directory of financial assistance programs for vision care.
Why Online Vision Tests Aren’t a Substitute
Online vision tests can give you a rough sense of your visual acuity, but they cannot replace an in-person exam. They don’t check eye pressure, examine your retina, test peripheral vision, or evaluate how your eye muscles track together. That means they can’t detect glaucoma, macular degeneration, diabetic eye damage, or other conditions that develop without obvious symptoms.
Prescriptions from online tests also tend to be less precise. In an office, the doctor fine-tunes your prescription in real time based on your feedback and takes physical measurements of your cornea to ensure contact lenses fit properly. A poor contact lens fit can cause headaches, nausea, eye pain, and blurry vision. Online tests are fine as a convenience tool between comprehensive exams, but they capture only a small fraction of what an in-person visit reveals.
Eye Exams for Children
Pediatric exams look different from adult visits and follow a specific developmental timeline. At birth, a doctor checks for a “red reflex” by shining a light into each eye (similar to the red-eye effect in flash photography). The absence of a red reflex can signal serious problems. They also check that the baby blinks in response to light and that the pupils constrict normally.
Between 6 and 12 months, the pediatrician re-checks those basics and also looks at eye alignment and movement. Between 12 and 36 months, a photoscreening test may be used: a special camera photographs the child’s eyes to detect problems that could lead to amblyopia (lazy eye). These early screenings matter because many childhood vision problems are highly treatable when caught young but can cause permanent issues if missed.
Children at higher risk, including those with a family history of childhood cataracts, glaucoma, or retinoblastoma, should see an ophthalmologist as early as possible rather than waiting for routine screening milestones.
