Eye Exam Length Depends on Your Needs
You’ve got a 2 p.m. call, a walk back to the office, and a calendar with no white space. Before you book an eye exam at Lunettes Optometric, you want to know exactly how much of your afternoon the appointment will take.
Plan on 30 to 60 minutes for a routine eye exam, and closer to 90 minutes if your eyes are dilated or you’re also doing a contact lens fitting or a dry eye consult. Knowing which type of appointment you’re booking helps you block the right amount of time on your calendar, whether you’re coming in for an adult eye exam or something more involved.
What Happens During Your Exam & How Long Each Part Takes
Health History & Preliminary Tests
Your visit starts at the front desk with your vision plan details, a list of your medications, and any past eye history. A technician then walks you through a few quick checks.
These preliminary tests usually cover eye pressure, your peripheral vision, and imaging. Each one takes a couple minutes. You’ll be finished with this part of your eye exam in about 10 to 15 minutes total.
Time with Your Eye Doctor
Next comes the part you picture when you think of an eye exam. You’ll read an eye chart off the wall while your optometrist fine-tunes your prescription. This is the lens-by-lens comparison where you pick which lenses look clearer.
Your eye doctor will also use a slit lamp to look closely at the front of your eyes. Expect questions about your screen time, any dryness or grittiness by late afternoon, what your hobbies are, and headaches. Answer honestly here. These details are important for your eye health and your final prescription.
Factors Affecting Appointment Length
A few situations can make your appointment last longer.
- A first visit means paperwork at the office if you didn’t complete it online.
- A contact lens fitting adds time, especially if you’re learning to insert and remove lenses for the first time.
- If your appointment is a dry eye evaluation or a myopia control appointment for your child, these exams involve additional testing.
Dilation & What to Expect After
In some cases, your eye doctor may recommend eye dilation as part of your exam. Dilation drops need up to 30 minutes to take effect, so this adds extra time to your appointment.
Once the drops kick in, your eyes will be light sensitive for several hours. Nowadays, in many cases, optometrists use retinal photos rather than eye drops, so ask your optometrist ahead of time what you should expect.
Your Drive Home & Screen Time Afterward
If you’re getting dilation drops, bring sunglasses for after your appointment and plan a ride home or back to the office rather than driving yourself.
Close-up work is generally harder until the eye drops wear off, so save these kinds of tasks for later in the day.

How to Prepare & Shorten Your Visit
Small steps before you arrive can trim real time off your appointment. Start with these three:
- Fill out your forms before you walk in the door.
- Bring your ID, your vision plan information, and your current glasses.
- Write down your symptoms and your medications so nothing gets missed.
Morning or Afternoon Appointment?
Morning slots work well if you’re heading into the Financial District and want your exam done early.
Late-day visits have their own advantage. If your eyes feel dry and tired after 8 hours in front of a screen, your eye doctor can see them exactly as they are at the end of the day.
What Comes After Your Exam
Once the clinical part of your appointment wraps up, your optical team can help you try on frames and find shapes that suit your face and your prescription. Give yourself 20 to 30 extra minutes if you want to choose frames.
Glasses are typically ready in 7 to 10 business days. If you wear contacts, you can often leave with trial lenses the same day, while your full order ships later.
When to Book Your Next Exam
Many adults do well with a yearly exam, though this often depends on the health of your eyes. Children can have a first exam by 12 months of age, and anyone managing an ongoing eye concern may need to come in more often.
If your vision changes or new symptoms appear between visits, book sooner rather than waiting for the calendar reminder.
Book a Time That Fits Your Day
An eye exam doesn’t have to eat your afternoon. With your forms done and the right appointment type on the books, you can be in and out in about an hour.
