How to Prepare for an Eye Exam
Before Your Appointment
According to the AAO and AOA clinical practice guidelines, your family history of eye conditions directly informs your doctor's screening decisions. Write down whether any blood relatives have had glaucoma, macular degeneration, cataracts, retinal detachment, or color blindness. Also list family history of diabetes and cardiovascular disease, since both affect eye health.
Write down every prescription drug, over-the-counter medication, vitamin, and supplement you take, including dosages. Beta-blockers, antihistamines, antidepressants, and corticosteroids all affect eye pressure, tear production, or pupil response. Your eye doctor interprets exam findings differently depending on what medications you are taking.
Note any changes in your vision, eye comfort, or eye appearance. Record when symptoms started, how often they occur, and whether anything makes them better or worse. Prepare two to three questions you want your doctor to answer. Written notes keep the appointment focused and prevent you from forgetting something important.
Contact Lens Preparation
According to standard optometry protocol, you should remove soft contact lenses at least two hours before a comprehensive eye exam. Contacts alter corneal shape and tear film, which can skew refraction results. Wearing contacts to the appointment makes your prescription measurement less accurate.
If you are scheduled for a contact lens fitting or evaluation, wear your contacts for at least two hours before arrival so your doctor can assess how the lenses fit and function on your eyes. According to the AOA evidence-based guideline, your doctor needs to see the contacts in action to evaluate comfort, movement, and vision.
Always bring your glasses to the appointment even if you normally wear contacts. If your doctor needs you to remove your contacts during the exam, you will need glasses to see on the way home. Your doctor also measures your glasses prescription for comparison.
Plan for Dilation
Dilation is standard in comprehensive exams for adults, especially those age 40 and older. According to the AAO, dilating drops blur your near vision and increase light sensitivity for four to six hours. Arrange a driver or ride service so you do not have to decide whether you are safe to drive after the exam.
Book a morning appointment if possible so dilation effects fade by afternoon. Avoid scheduling detailed close-up work, important meetings, or activities that require sharp near vision for the rest of the day. If you must return to work, plan tasks that rely on distance vision or can tolerate some blur.
Sunglasses reduce the glare and discomfort that come with dilated pupils. Polarized or wraparound styles provide the best coverage. Even indoor lighting can feel uncomfortably bright after dilation, so keep your sunglasses handy until your pupils return to normal size.
Day-of Preparation
There is no need to fast before a routine eye exam. Take your regular medications on schedule. Your eye doctor needs to see your eyes in their typical medicated state. If you have diabetes, eating normally keeps your blood sugar stable, which affects your exam results.
If your doctor plans to examine your eyelids closely or perform testing for dry eye, consider skipping eye makeup on exam day. Mascara, eyeliner, and eyeshadow can interfere with tear film measurements and eyelid evaluation. Some clinics ask patients to arrive without eye cosmetics for certain tests.
Plan to arrive 10 to 15 minutes before your appointment to complete any remaining paperwork and settle in. If your office offers online intake forms, complete them at home to save time. Arriving rushed can elevate your blood pressure, which your doctor may check during the exam.
What to Expect During the Exam
A technician reviews your health information, medications, and symptoms. At a first visit, this takes about 10 minutes. Return visits are shorter because your records are already in the system. The technician may also perform preliminary tests like visual acuity, auto-refraction, and eye pressure measurement.
Your eye doctor performs a refraction (prescription measurement), slit-lamp exam (microscopic evaluation of the front of your eye), and eye pressure check. If dilation is included, the doctor examines the retina and optic nerve after the drops take effect. Ask questions during the exam while your doctor can show you findings in real time.
Your doctor discusses results and recommendations before you leave. You receive a new prescription if your vision has changed. If additional testing or follow-up is needed, the office schedules your next visit. Collect your sunglasses and ride before heading out if you were dilated.
Preparing for Specific Exam Types
Your first comprehensive exam is the longest because your doctor establishes baseline measurements for every part of your eye. Bring as much health history as possible. Expect the visit to take 60 to 90 minutes. Your doctor will explain each test before performing it.
If you have diabetes, bring your most recent hemoglobin A1c result and blood sugar log. Your eye doctor checks for diabetic retinopathy and other diabetes-related changes. Dilation is essential for this exam. Know your endocrinologist's name and contact information in case your eye doctor needs to coordinate care.
Parents should bring school screening results, teacher feedback on vision concerns, and the child's medication list. A familiar toy or tablet can help younger children stay calm. Explain to your child that the doctor will look at their eyes with a bright light and ask them to read letters or pictures. No part of the exam hurts.
Eye Exam Preparation Questions
Caffeine can temporarily raise eye pressure by a small amount. If your doctor is monitoring you for glaucoma, consistent caffeine habits help ensure comparable measurements between visits. You do not need to skip your morning coffee, but mention your caffeine intake if asked.
Do not stop any medications before a routine eye exam unless your doctor instructs you to. Your eye doctor evaluates your eyes in their typical medicated state. Stopping medications can change your exam results in misleading ways.
Tell your doctor at the beginning of the appointment. Eye doctors are experienced at working with anxious patients. Knowing your concern lets them explain each step before they do it, move at a comfortable pace, and check in with you throughout the exam. Deep breathing between tests also helps.
Light exercise is fine. Intense exercise can temporarily raise eye pressure, which may affect tonometry readings. If you have glaucoma or are being screened for it, schedule your exam before your workout or wait at least an hour after exercising.
That is common, and your eye doctor will not judge you. A thorough first exam establishes your current baseline. Bring whatever health information you can, including a medication list and family history. Your doctor may recommend additional testing to check for conditions that could have developed during the gap.
Tell your eye doctor if you are pregnant or breastfeeding. Pregnancy can temporarily change your prescription and affect your tear film. Some dilation drops may not be recommended during pregnancy. Your doctor can adjust the exam accordingly to keep you and your baby safe.
Get Ready for Your Appointment
Remove contacts two hours early, bring your glasses and insurance cards, write down your medications and questions, and arrange a ride if dilation is planned. A few minutes of preparation makes your exam more efficient and your results more accurate.
