Block out for an hour and you'll rarely be caught out.
A routine comprehensive exam usually runs 30 to 60 minutes. Add contact lenses, dilation, or a first visit, and you're closer to 90. Here's the breakdown so you can plan properly rather than guessing.
The exam isn't one test. It's a sequence, and each part is quick, which is why the total surprises people.
History and symptoms first, then visual acuity the chart everyone pictures. Refraction after that, where you compare lenses and tell us which looks clearer. That's the part that produces your prescription and it takes around ten minutes on its own.
Then the health side. Eye pressure measurement for glaucoma screening. A slit lamp examination of the front of the eye at high magnification. An assessment of how the two eyes work together. A look at the retina and optic nerve, with or without dilation.
Color vision and peripheral field testing where appropriate.
Every one of those takes two to five minutes. Stack them and you're at half an hour before anyone has discussed results with you.
Longer, and the time doesn't end when you leave.
Dilating drops need around 20 to 30 minutes to take full effect before we can examine anything, and longer for some people. So a 40-minute exam becomes 70 minutes with a wait in the middle.
The part people underestimate is afterwards. Pupils can stay dilated for up to six hours. You'll be light-sensitive, near vision will be blurry, and screens become difficult. Plenty of people manage to drive home, though it isn't comfortable and it isn't advisable in bright conditions.
If you're being dilated, plan for it. Bring sunglasses. Arrange a lift if you can. And don't schedule it for the morning of a day you need to read anything.
This is worth knowing before you book anywhere.
Wide-field retinal imaging photographs most of the retina without drops. We use Optomap at both offices, which captures the image in a fraction of a second and gives us a permanent record to compare against at your next visit something a dilated look through a lens can't do.
It doesn't replace dilation in every case. Certain findings, certain symptoms, and some high-risk patients still need drops for a full view. But for a lot of routine exams, it means no waiting period, no blurry afternoon, and you drive yourself home.
If your time is tight, ask about it when you book.
Here's the practical failure I see most often.
Someone books a 45-minute appointment in their lunch break. The exam finishes on time. Then they need to choose frames, get measurements taken, discuss lens options, and sort out insurance and that's another 30 to 45 minutes they hadn't allowed for.
So they rush it, pick something they're lukewarm about, and wear it for two years.
If you're expecting a new prescription, treat the optical part as a separate appointment in your head even though it happens in the same visit. Give it its own half hour. And if you're being dilated, choose frames before the drops go in, because judging how something looks on your face is genuinely harder afterwards.
Fill in any forms before you arrive. Most practices email them now and it saves ten minutes at the desk.
Bring your current glasses and your contact lens boxes. The boxes matter more than people think they carry the exact parameters, which saves us reconstructing them.
Bring a list of your medications. A surprising number affects the eyes.
Know your family history, particularly glaucoma, macular degeneration and diabetes. If you don't know, ask before you come.
Have your insurance details ready and mention them when booking so the benefit can be checked in advance.
And say what you're there for when you make the appointment. "I want to try contacts" or "I've been getting headaches" changes how much time gets allocated. Turning up and mentioning it at the end is what causes appointments to overrun.
You'll see very short appointment slots advertised. Worth understanding what they are.
A 15-minute test is a refraction enough to produce a prescription and nothing more. It doesn't include pressure testing, a proper look at the retina, or an examination of the eye's health.
That's fine if you're a young adult updating a stable prescription. It's inadequate if you're over 40, diabetic, have a family history of glaucoma, or have noticed anything changing. Glaucoma and diabetic retinopathy cause no symptoms until they're advanced, and they're found on the parts of the exam a quick refraction skips.
The length of an appointment is usually a decent proxy for what's in it.
Briefly, since it's the other thing people want to know when they're booking: without insurance, expect roughly $69 to $250 depending on the type of practice, with a national average around $110. With a vision plan, most people pay a small copay or nothing.
Contact lens fittings are billed separately on top.
There's a fuller breakdown of what drives the price, including what should be included and what gets added, in our guide to eye exam costs.
Glasses generally take 7 to 10 business days, faster for simple single-vision lenses and longer for complex prescriptions or specialist coatings.
Contact lenses usually arrive within about a week, though you'll often leave with trial lenses on the day, so you can start wearing them straight away.
First-time contact lens wearers need a follow-up appointment a week or two later to check how the lenses are sitting. Budget for that when you're planning.
Both offices are open seven days a week, which helps if weekday appointments are difficult.
Tell us what you need when you call and we'll allocate the right amount of time a contact lens fitting in a routine slot is the main cause of anyone feeling rushed.
Jersey City is on 201-420-7733. Florham Park on 973-994-1444.
Around 45 to 60 minutes, sometimes longer with young children since testing has to be adapted to their attention span. Booking earlier in the day tends to go better.
After an undilated exam, yes. After dilation, it's legal but uncomfortable, and bright daylight makes it harder. Bring sunglasses at minimum and arrange a lift if you can.
No. It depends on your age, your prescription, your risk factors, and when you were last dilated. Wide-field retinal imaging covers many routine cases without drops.
Every one to two years for most healthy adults, annually from 60, annually if you wear contact lenses, and annually if you have diabetes regardless of age.
That was almost certainly a refraction rather than a comprehensive exam. Useful for a prescription, not sufficient for eye health.
So, how long does it take for an eye test? Half an hour at the quick end, an hour and a half with dilation and contact lens fitting.
Allow an hour as your default, add half an hour if you're choosing frames, and tell the practice what you need when you book. That's most of it.
There's a version of this article that gives you five exercises and wishes you luck. I'm not writing that one, because eye exercises help exactly one cause of double vision and do nothing for the rest.
Worse, some causes of double vision need attention today, and spending a fortnight on exercises instead is the wrong outcome.
So: how to work out which kind you have, when exercises are genuinely the answer, and what the exercises are.
This takes ten seconds and tells you more than anything else you'll read here.
Cover your left eye. Then your right. Does the doubling disappear when either eye is covered?
If it disappears you have binocular diplopia. Both eyes work individually, but they're not pointing at the same place. This is an alignment problem: muscles, nerves, or the coordination between them. Exercises are only relevant in this group, and only for some of it.
If it persists with one eye covered that's monocular diplopia. The doubling is happening inside one eye, usually because light is being split before it reaches the retina. Astigmatism, cataracts, dry eye, corneal irregularity. Exercises are completely useless here. A pinhole test usually clears it, which points straight at a refractive cause, and glasses or treating the cataract is what fixes it.
Most people who go looking for eye exercises for double vision have never done this test. Do it before you do anything else.
Skip everything below and get assessed urgently if any of this applies.
Double vision that came on suddenly, over hours or a day or two. Acute binocular diplopia is a red flag in its own right and standard guidance is to investigate it urgently.
A drooping eyelid alongside it. A pupil that's larger on one side, especially with headache that combination is a neurosurgical emergency and needs same-day imaging.
Any facial droop, arm weakness, slurred speech or sudden confusion. That's a stroke call, meaning 911.
Pain around or behind the eye, particularly on moving it.
If you're over fifty with new double vision plus a headache, scalp tenderness, or jaw ache when chewing giant cell arteritis needs excluding quickly, because it can take sight permanently.
Double vision that's worse in the evening and better first thing in the morning, or that comes and goes with fatigue. That pattern suggests myasthenia gravis and needs proper testing.
Double vision after a head injury.
One more thing that no article on this seems to mention: stop driving until someone has assessed you. New-onset diplopia is a driving risk regardless of cause.
Your eyes have to turn inward together to focus on anything close. When that inward movement is weak or poorly sustained, near work becomes a struggle and when it fails, the image splits.
The signature pattern: double vision that only happens close up, comes on after twenty or thirty minutes of reading or screen work, gets worse when you're tired, and disappears entirely when you look across the room. It's been there for months or years rather than arriving last Tuesday.
That's a benign condition. It's common, particularly in students and people doing heavy near work. And it responds to exercises, which is why exercises have a reputation they only half deserve.
If your double vision doesn't match that description, exercises aren't your answer.
These are for convergence insufficiency, confirmed by an exam. I'd rather you did them knowing that than started them on a guess.
Pencil push-ups. Hold a pen at arm's length, a small letter on it at eye level. Focus on the letter and bring it slowly towards your nose, keeping it single. When it doubles, stop, hold there a moment, then move it back out until it's single again. Repeat for around fifteen repetitions, once or twice daily. The point is finding where your convergence gives out and gradually pushing it closer.
Brock string. A length of string with three beads on it, one end held at your nose. Focus on the near bead you should see the string forming an X crossing at that bead. Move your focus to the middle, then the far one, and watch how the X shifts. This gives you feedback on where your eyes are pointing, which push-ups don't.
Near-far focus shifts. Something small held at reading distance, something across the room. Alternate between them, ten seconds each. Less about convergence strength and more about the switching being smooth.
A realistic note on results. Home exercises help a proportion of people with convergence insufficiency. Supervised in-office therapy performs better in trials, and this is one of the few areas of vision training where the evidence is solid rather than promotional. If six weeks of home work hasn't shifted anything, that's information, not failure.
Because most double vision isn't convergence insufficiency.
Prisms. Ground into your glasses or applied as a stick-on Fresnel, they shift the image so your eyes receive it in alignment. This is the workhorse treatment for small stable misalignments, and it works when nothing else will.
Treating what's underneath. Thyroid eye disease, myasthenia, diabetes-related nerve palsies the double vision improves as the condition is managed. Microvascular palsies from diabetes or high blood pressure often resolve on their own within about six months.
Patching or occlusion. Not a cure, but covering one eye or frosting one lens eliminates the doubling while you wait for something else to work. Useful for people who need to function meanwhile.
Surgery. Eye muscle surgery for large or long-standing misalignments that prisms can't manage.
Botulinum toxin. Occasionally used to temporarily weaken an overacting muscle while a palsy recovers.
The whole question here is which of these you're dealing with, and that isn't something you can determine at home beyond the cover test.
What an exam adds: measuring the size and direction of the misalignment, checking each muscle's range of movement, testing near point of convergence with a target, looking at your pupils, checking for lid droop or bulging, and examining the retina and optic nerve.
That's what separates a convergence problem from a nerve palsy, and a nerve palsy that can be watched from one that needs imaging this week.
If it turns out to be convergence insufficiency, the exercises above are appropriate and you'll know they're aimed at the right target. If it's something else, you'll have found out in an hour rather than after two months of pencil push-ups.
Both New Jersey offices see patients for this.
Jersey City is on 201-420-7733, Florham Park on 973-994-1444. Call the same day if anything in the red flags section applies.
For convergence insufficiency, often yes though some people need occasional refresher periods. For every other cause, no. Exercises don't repair a cranial nerve palsy or realign an eye affected by thyroid disease.
Six to twelve weeks of consistent daily practice for convergence insufficiency. Doing them sporadically achieves very little, which is the usual reason people conclude they don't work.
Some kinds. Microvascular nerve palsies related to diabetes or blood pressure often resolve within six months without treatment. That's a conclusion for an examination to reach, not one to assume.
Usually less alarming than the binocular kind. Monocular diplopia typically comes from astigmatism, a cataract, dry eye or corneal irregularity rather than anything neurological. It still needs identifying, because a cataract causing it is worth treating.
Convergence insufficiency is common in school-age children and treatable. A child with double vision needs examining first though, and a child who has suddenly developed it needs examining promptly.
The honest summary on eye exercises for double vision: they're effective, narrowly. One condition, well defined, with real evidence behind the treatment.
The trouble is that the same symptom has a dozen causes, several of them urgent, and none of the others care how many pencil push-ups you do.
Cover one eye. Read the red flags. Then book an exam, and let the exercises follow the diagnosis rather than replace it.
Your child's eyes are doing more work than you might realize. Reading the whiteboard, catching a ball at recess, recognizing a friend across the playground, sounding out words on a page. All of it runs through their vision, and most of it is happening while their visual skills are still developing.
That's why it's never too early to pay attention to your child's eye health. Regular eye exams help support their sight at every age and every stage, and they catch the small problems before they turn into bigger ones.
If your child is nervous about their first visit, that's completely normal. Our optometrists work with kids all the time and know how to put them at ease. A lot of children end up enjoying the whole thing. And if it turns out your child needs glasses, we carry plenty of colors and styles they'll actually want to wear, in materials tough enough to survive everyday kid life.
The American Optometric Association recommends a simple schedule:
Good vision matters far beyond the eye chart. Clear sight is essential to how children learn, play, and grow, and it feeds into their social, cognitive, and motor development too.
Children aren't born with the visual skills they need. They build them gradually, the same way they learn to walk and talk.
And those skills carry a lot of weight in the classroom. Around 80% of what children learn comes to them through their eyes. Reading, copying notes, working with classmates, finding their footing in gym class. Vision is wrapped up in nearly all of it.
Here's the tricky part. A child who starts school with an undiagnosed vision problem often has no idea anything is wrong, so they don't say anything. They just struggle to keep up. Sometimes that struggle gets mistaken for ADHD or another behavioral issue when the real cause is sitting in front of everyone's eyes.
Vision problems that go unnoticed can also lead to:
A routine eye exam takes these possibilities off the table, or catches them early enough to do something about it.
A baby's eyesight changes fast in those first couple of years. Knowing the milestones helps you spot whether things are tracking the way they should:
You can give this development a nudge through play. Peek-a-boo and patty-cake do more than entertain. Hand your baby things they can hold and explore, and play games that involve dropping objects and picking them back up. The classic games are classics for a reason.
And when you want to be sure those skills are progressing at the right pace, a comprehensive eye exam is the way to check.
This is the question we hear most, and the honest answer is that it's hard to tell from the outside. When something is off with their vision, children usually can't put it into words. Often they don't even know there's a problem, because they have nothing to compare it to. An adult knows what clear sight is supposed to look like. A child has never had that baseline.
That's exactly what regular exams give them. By checking your child's vision consistently, we can establish what's normal for them, spot any issues early, and step in with treatments like myopia control when they're needed.
Setting your child up for a lifetime of healthy vision starts with a single appointment. Our team is here for your whole family at both of our New Jersey locations, and we'd love to welcome your kids in.

Glasses are great — but they're not for everyone, and they're not for every situation. If you've been curious about contacts, or if you've worn them before and want to revisit the option, the first step is a contact lens exam and fitting with one of our optometrists.
It's a straightforward process, and it opens up more options than most people expect. Here's what you need to know.
Book your contact lens exam today.
Before we can fit you for contacts, we need a full picture of your eye health. A comprehensive eye exam lets us check your prescription, assess the health of your eyes, and determine whether contacts are a suitable option for you.
Most people are good candidates. But there are some conditions that can affect whether standard contacts will work well, including dry eye, eye allergies, and a history of repeat eye infections. The good news is that even if one of those applies to you, it doesn't automatically rule out contacts. Specialty lenses exist for exactly these situations, and we can talk through what might work.
The most common lenses correct nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. For most people, one of these standard options will do the job perfectly well.
But we also fit patients in specialty lenses for more specific needs. These include:
Multifocal contacts — for people who need correction at both near and far distances, often used as an alternative to reading glasses for those with presbyopia.
Toric contacts — designed specifically for astigmatism, with a shape that stays correctly oriented on the eye.
Aspheric contacts — these have a more gradual curve than standard lenses and can reduce the glare and halos some people notice, particularly in low light.
Acuvue Oasys MAX 1-Day — a daily disposable lens with built-in blue light filtering and moisture technology, a good option for people who spend long hours on screens.
Prescription colored contacts — yes, you can change your eye color and correct your vision at the same time. These require a proper fitting just like any other lens.
MiSight for kids — a daily disposable lens clinically proven to slow the progression of myopia in children. If your child has been diagnosed with nearsightedness that's getting worse year on year, this is worth asking about.
If we spot a specific condition during your exam, we'll let you know which type of lens would suit you best.
Contacts sit directly on the cornea, so how you care for them matters. Serious eye infections can develop when lenses aren't used properly — and most of them are entirely preventable with a few habits.
Here's what we recommend to all our contact lens patients:
These aren't complicated, but they do need to be consistent. Most people who run into problems with contacts do so because they're cutting corners on one of these.
Whether you're new to contacts or returning to them after a break, we'll make sure you're fitted properly and comfortable with how to care for them before you leave. Our teams at both Jersey City and Florham Park are here to help.
