Getting your eyes checked starts with booking an appointment with an eye care professional, typically an optometrist for a routine exam. The process is straightforward: find a provider, schedule a comprehensive eye exam, and show up prepared with your health history. Most adults without symptoms or risk factors need an exam every two to four years before age 55, and every one to two years after 65. Here’s everything you need to know to make it happen.
Which Eye Professional to Choose
Three types of eye care professionals exist, and knowing the difference saves you time and money. For a standard checkup, an optometrist is your best starting point. Optometrists complete four years of specialized medical training after college and function like a primary care doctor for your eyes. They handle routine exams, diagnose common vision problems like nearsightedness and astigmatism, prescribe glasses and contacts, and screen for diseases like glaucoma.
An ophthalmologist is a physician (MD or DO) who completes medical school plus a one-year internship and three-year residency focused on eye care. Ophthalmologists can do everything an optometrist does, plus perform surgery and treat complex conditions like retinal detachments or advanced diabetes-related eye disease. You don’t need to see an ophthalmologist for a routine checkup unless you have a known eye condition or your optometrist refers you.
Opticians are the third piece of the puzzle, but they don’t examine eyes or write prescriptions. They help you select and fit glasses or contacts based on the prescription your optometrist or ophthalmologist writes.
How Often You Need an Exam
The schedule depends on your age and risk level. The American Academy of Ophthalmology recommends that healthy adults without symptoms get a baseline comprehensive eye exam at age 40. Before that, routine exams aren’t strictly necessary for people with no vision complaints or risk factors. After the baseline:
- Ages 40 to 54: Every 2 to 4 years
- Ages 55 to 64: Every 1 to 3 years
- Ages 65 and older: Every 1 to 2 years
If you’re at higher risk, the timeline tightens. African Americans face elevated glaucoma risk and should consider exams every two to four years even before age 40. People with diabetes, a family history of eye disease, or those taking medications with eye-related side effects generally need annual exams. The American Optometric Association takes a slightly more aggressive stance, recommending exams at least every two years for all adults 18 and older, with annual exams for anyone at risk.
For children, the first eye assessment should happen between 6 and 12 months of age. Kids should be checked at least once between ages 3 and 5, then annually starting before first grade. Children can’t always articulate that they’re having trouble seeing, so sticking to this schedule catches problems early, particularly amblyopia (lazy eye), which responds best to treatment in young children.
What Happens During the Exam
A comprehensive eye exam takes roughly 30 to 60 minutes and covers far more than just reading letters off a chart. Your doctor will start with questions about your health history, any vision changes, and medications you take. Then the testing begins.
Visual acuity testing is the familiar part: reading rows of progressively smaller letters on a chart, one eye at a time. This measures how sharp your vision is at a distance. If you need correction, the doctor will use a device called a phoropter (the machine with all the lenses that flips back and forth) to dial in your exact prescription. You’ll be asked “which is better, one or two?” repeatedly until the sharpest option is found.
Beyond that, the doctor checks your eye pressure to screen for glaucoma, usually with a quick puff of air or a gentle probe that touches the surface of your eye after numbing drops. A slit lamp, which is essentially a high-powered microscope with a bright light, lets the doctor examine the front structures of your eye: the cornea, iris, and lens. They’ll also evaluate how well your eyes work together, checking alignment and how smoothly they track moving objects.
Dilation: What to Expect
For a thorough look at the back of your eye, including the retina and optic nerve, your doctor will likely dilate your pupils using eye drops. Dilation takes about 15 to 30 minutes to kick in and allows the doctor to examine up to 240 degrees of the retina, including the far edges where tears and detachments tend to occur. The three-dimensional view through dilated pupils is particularly valuable for evaluating optic nerve health, which is critical for catching glaucoma.
The trade-off: dilation generally lasts 4 to 24 hours. During that time, you’ll experience blurry vision (especially up close), sensitivity to bright light, and difficulty focusing. Bring sunglasses, and plan to have someone else drive you home if your vision is significantly affected. Some people’s eyes return to normal within a few hours, while others stay dilated most of the day.
Many offices now offer digital retinal imaging as an alternative or supplement to dilation. Advanced imaging systems can capture up to 97% of the retina without drops, provide instant digital images, and detect subtle changes like tiny hemorrhages or early signs of macular degeneration. There’s no recovery time. However, dilation still remains the gold standard for evaluating the far periphery of the retina and providing the stereoscopic, three-dimensional view that imaging can’t fully replicate. Some doctors recommend both for the most complete picture.
Contact Lens Exams Are Separate
If you want contacts, a standard eye exam alone isn’t enough. Contact lenses sit directly on the surface of your eye, while glasses sit about 12 millimeters away, so the prescriptions are fundamentally different. A contact lens exam includes additional measurements of your eye’s curvature and size to determine the right lens fit. Your doctor will also evaluate whether your eyes produce enough moisture for comfortable lens wear. This fitting typically costs extra and is billed as a separate service from your comprehensive exam.
How Much It Costs
Without vision insurance, a routine eye exam averages $136 nationally, with prices ranging from $105 to $257 depending on your location and the provider. With a vision insurance plan, the average out-of-pocket cost drops to about $25, ranging from $20 to $49.
Vision insurance and medical health insurance work differently for eye care. Vision plans are usually purchased separately and cover routine exams, frames, lenses, and contacts. Your medical health insurance typically covers eye visits only when you’re being treated for an eye disease or a medical condition that affects your eyes, such as diabetes, glaucoma, cataracts, or infections. If you’re going in purely for a glasses prescription with no underlying medical issue, that falls under vision insurance.
If you don’t have any insurance, large retail chains and warehouse stores with optical departments often offer lower-cost exams. Some community health centers and optometry schools provide reduced-fee or sliding-scale exams as well.
How to Prepare for Your Appointment
A little preparation makes the visit smoother and more useful. Bring your current glasses or contacts, even if the prescription is old. If you have a copy of your previous prescription, bring that too. Write down any medications you’re taking, including over-the-counter supplements, since certain drugs can affect your eyes or vision. Antihistamines, blood pressure medications, and some antidepressants are common culprits.
Know your family’s eye health history. Glaucoma, macular degeneration, and other eye diseases run in families, and this information directly affects how your doctor screens you. If you’ve noticed specific symptoms like difficulty reading at night, eye strain from screens, or occasional blurriness, note when they happen and how often so you can describe them clearly.
If you’ve had LASIK or another refractive surgery, you still need regular exams every one to two years. The surgery corrected your vision, but it didn’t eliminate the need to monitor your overall eye health.
Symptoms That Need Urgent Attention
Some eye problems can’t wait for a scheduled appointment. Sudden vision loss, even if it’s temporary or in only one eye, requires immediate evaluation. The same goes for sudden onset of flashing lights, a shower of new floaters, or a shadow or curtain moving across your field of vision, all of which can signal a retinal detachment.
Other symptoms that warrant urgent or emergency care: eye pain paired with vision changes, double vision, chemical exposure to the eye, a foreign object you can’t flush out, eye trauma from an impact, and signs of infection like significant redness with discharge. For these situations, go to an emergency room with eye care capabilities or an urgent ophthalmology clinic rather than waiting for a routine appointment.
Finding a Provider
If you have vision insurance, your plan’s website will have a provider directory filtered by location. Without insurance, you can search the American Optometric Association’s doctor locator or simply look for optometrists near you with strong reviews. Retail optical chains in pharmacies and big-box stores are a convenient, often affordable option for straightforward exams. For children, your pediatrician handles basic vision screenings at well-child visits, but a pediatric optometrist or ophthalmologist can provide a more thorough evaluation when needed.
When booking, ask whether the office accepts your specific insurance plan, whether dilation is included or optional, and whether a contact lens fitting is billed separately if you need one. Most offices can get you in within a week or two for a routine exam, though availability varies by location.
