A first visit to an eye clinic is not quite like seeing any other doctor. Before you meet the doctor you may read letters off a chart, rest your chin in two or three different machines and feel a small puff of air against your eye. Some visits also involve drops that widen the pupils and leave the world bright and blurred for the rest of the afternoon.
None of it hurts, and knowing the order takes away most of the surprise. This page walks through a typical first exam and then covers what to pack. The tests and their order vary with the clinic, the country and the reason you came, so read it as a common pattern rather than a fixed script. If you have a sudden change in vision or a painful eye, do not wait for a routine appointment: the urgent symptoms are listed at the end.
Step by step
1. Check-in and your health history
At the desk you will usually show ID and, depending on where you live, an insurance card or your health service details, plus any referral letter. Then comes a form or a short interview. Expect questions like these:
- What brings you in, since when, and which eye
- Health conditions such as diabetes or high blood pressure
- Every medicine you use, including tablets from other doctors and any eye drops
- Allergies
- Past eye surgery or injuries
- Eye disease in the family, glaucoma in particular
- Driving, screen work and sports, since they shape what you need from your eyes
If small print is hard for you, bring reading glasses for the form. Staff can help you fill it out.
2. The vision test
You read a chart across the room: letters in many countries, pictures for young children, and in Japan usually a ring with a gap whose direction you point to. Each eye is tested on its own, first without correction and then with glasses or lenses. Eye doctors pay most attention to the best corrected result. If the right lenses still cannot make the chart clear, something other than your prescription may be involved, and the rest of the exam looks for it.
Depending on the country, these early tests may be done by a technician, an orthoptist or an optometrist before you see the doctor.
3. Refraction
You look into a machine at a picture, often a road, a house or a hot-air balloon far away, while it estimates how nearsighted, farsighted or astigmatic each eye is. Relax and let the picture sit there; straining makes the reading less accurate. Many clinics then fine-tune by placing lenses in front of your eyes and asking which looks clearer, the first or the second. There are no wrong answers, and "they look the same" is a useful one.
4. Eye pressure
Some clinics measure the pressure inside the eye with a quick puff of air. Others put in numbing drops and touch the surface gently with a small instrument. Either way it is over in seconds and does not hurt. Pressure is one of the clues for glaucoma, but glaucoma can damage the optic nerve while the pressure stays in the normal range (this form is common in East Asia), so nobody judges glaucoma on pressure alone.
5. The slit lamp
In the exam room you rest your chin on a support and lean your forehead against a band while the doctor looks through a microscope that throws a narrow, bright beam of light. It gives a magnified view of the lids, the white of the eye, the clear front window called the cornea, and the lens, where cataracts form. This is a good moment to describe your symptoms and ask questions.
6. The back of the eye
To see the retina, the optic nerve and the blood vessels, the doctor may put in drops that widen the pupils, which gives a much fuller view. Many clinics also take photographs, or a scan that shows the layers of the retina in cross-section. Whether to dilate is the doctor's decision, based on your symptoms and what the earlier tests showed.
7. Results and next steps
You hear what the tests found and what happens next. That may be a prescription for glasses or drops, a date to come back, or further tests such as a visual field test, which maps how much you can see toward the edges and is often booked for another day. Costs depend on which tests were done, so a first visit can cost more than later ones.
If your pupils are dilated
The drops usually take 15 to 30 minutes to work. After that, for several hours and sometimes longer, light feels harsh and close focus is poor. Phone screens and paperwork are the hardest.
Do not drive, ride a motorcycle or cycle until your vision is back to normal. Because the decision to dilate is often made during the visit, the simplest plan for a first exam is to leave the car at home: take public transport, or ask someone to drive you. Sunglasses or a wide-brimmed hat make the trip home more comfortable.
Allow plenty of time. Waiting, extra tests and dilation can stretch a visit well past an hour, so if you are taking time off work, half a day is a safer plan than one hour.
What to bring
| Item | Why it helps |
|---|---|
| ID, plus insurance or health service details where your system uses them | Needed to register and, in many places, to bill the visit |
| A list of every medicine you take | Tablets from other doctors can matter for your eyes, and the doctor needs to know about any drops |
| Your current glasses, every pair | The doctor can check that your distance, reading or computer pair still suits you |
| Contact lens details | The box, packet or prescription showing lens type and power |
| Notes on your symptoms | When it started, which eye, what you notice, what makes it better or worse |
| Sunglasses or a hat | For the bright trip home after dilation |
| Referral letter and earlier results | If another doctor or optometrist has given you any |
| Reading glasses | For filling out forms |
If you wear contact lenses, ask when you book whether to come with them in or out. Some clinics want lenses left out for a while before they measure you for glasses, because lenses can briefly change the shape of the front of the eye. Bring your lens case and glasses either way.
Your notes are worth more than they look. Plenty of people go blank in the exam chair. A line such as "worst first thing in the morning" or "the right eye looks different when I close the left" tells the doctor a lot.
Two small things for the day itself. Go light on eye makeup, which can get in the way of some tests. And try to arrive with your eyes in their usual state, since a late night of screens can make vision seem worse than it normally is.
Bringing someone with you
You may be perfectly able to go alone, but company helps at two points: getting home after dilation, and hearing important news about treatment or surgery. Two people remember more of an explanation than one.
If you are going with an older relative, let them speak for themselves and fill gaps only when needed. Some small clinics have cramped waiting rooms and ask companions to keep numbers down, so check ahead if more than one person is coming.
Taking a child
Children rarely complain about poor vision, because they have nothing to compare it with. Amblyopia (lazy eye) affects about 2 to 3 of every 100 children, and treatment works best early, while vision is still developing, which it does most until about age 7 or 8. Many countries offer vision screening for young children; ask your child's doctor or health visitor what is available where you live. If a screening suggests an eye exam, book it soon. Lazy eye and early vision checks goes into more detail.
A few things make the visit easier:
- Book a time when your child is usually rested and fed.
- Explain beforehand in simple words: "You'll look at pictures inside a machine, and the doctor will shine a little light."
- Pack a quiet book or small toy for the wait.
- Bring screening results, your child's health record and any insurance details.
To measure a child's prescription accurately, the doctor may use drops that relax the eye's focusing. Some of these last longer than the drops used for adults, so ask how long the effect will last and plan school, sports and outdoor play around it, with a hat or sunglasses for the brightness.
Questions to write down
If you are not sure what to ask, these three cover a lot:
- What did today's tests show, and what is still unclear?
- When should I come back?
- What changes mean I should come back sooner?
If drops are prescribed, check how to put them in, how often, and how long to wait between different kinds. Do not stop using them because your eyes feel better; raise it at the next visit instead. Put the next appointment in your calendar before you leave the building.
When not to wait for a routine first visit
Everything above assumes a planned visit. These symptoms do not fit that plan:
- Sudden loss of vision in one eye, even if it returns within minutes, can be a warning sign of stroke. Severe eye pain with blurred vision, haloes, headache and nausea can be acute angle-closure glaucoma. Both are emergencies: call your local emergency number, such as 911, 999, 112, or 119 in Japan, or go to an emergency department.
- New flashes of light, a sudden shower of floaters, or a curtain over part of your vision can mean a retinal tear or detachment. Get eye care the same day.
- After a chemical splash, rinse with plenty of clean water for at least 15 minutes, then get urgent care.
- Any eye injury needs to be seen promptly.
