Comprehensive eye exams are essential for protecting your vision and overall health. While you might think your eyes are fine if you can see clearly, many serious eye diseases develop without symptoms in their early stages. Regular exams allow us to detect problems before they affect your sight, and often before you even notice anything is wrong.
At Longwood Eye & LASIK Center, we use advanced diagnostic technology to evaluate not just your vision, but the complete health of your eyes. These thorough examinations can catch conditions early when they’re most treatable, helping you preserve clear, healthy vision for years to come.
What is a Comprehensive Eye Exam?
When most people think of eye exams, they picture reading letters on a wall chart. But comprehensive eye exams are so much more. We take your eye health seriously, which is why we continually invest in the latest technology to give you the most thorough evaluation possible.
Our comprehensive exams check your vision quality, screen for eye diseases, and examine the overall health of your eyes from front to back. Here’s what we evaluate:
Visual Acuity Test
This is the classic eye chart test you’re familiar with. You’ll cover one eye and read letters that get progressively smaller as you move down the chart. This gives us a baseline measurement of how well you see at various distances.
Refraction Assessment
When light enters your eye, it bends (refracts) as it travels to the retina at the back of your eye. If those light rays don’t focus on the right spot, you have a refractive error (nearsightedness, farsightedness, or astigmatism).
We use a phoropter to fine-tune your prescription. We’ll rotate different lenses in front of your eyes and ask, “Which is better, one or two?” This helps us determine exactly what correction gives you the clearest vision possible.
Visual Field Test
This test determines whether you have difficulty seeing in any areas of your overall field of vision. You’ll look into an automated perimetry machine and press a button each time you see a blinking light. This test is crucial for detecting conditions like glaucoma that can affect your side vision.
Eye Muscle Test
We’ll have you follow a moving object with your eyes while we watch your eye movements. This simple test checks for muscle weakness, poor control, or coordination problems between your eyes that could affect your vision or cause double vision.
Color Vision Test
To check for color vision problems, we’ll show you several multicolored dot-pattern tests with numbers or shapes hidden within the patterns. If you have colorblindness, certain numbers or shapes will be difficult or impossible for you to see.
Slit-Lamp Examination
The slit lamp is essentially a microscope that illuminates and magnifies the front of your eye. This allows your eye doctor to closely examine your eyelids, lashes, cornea, iris, lens, and the fluid chamber in your eye. They can spot early signs of cataracts, corneal problems, and other conditions that affect the front structures of your eye.
Retinal Examination
This exam examines the back of your eye, where the retina, optic nerve, and blood vessels are located. We’ll usually dilate your pupils with eye drops to get the best view.
This exam can reveal signs of macular degeneration, diabetic retinopathy, retinal detachment, and even systemic health problems like high blood pressure and diabetes.
Glaucoma Screening
Glaucoma is a disease where pressure builds inside your eye, gradually damaging the optic nerve and stealing your vision. However, most people don’t notice symptoms until significant damage has occurred.
Your eye doctor will measure the pressure inside your eyeball (intraocular pressure). If the pressure is elevated, we can catch glaucoma early and help preserve your vision with treatment.
Pediatric Eye Care at Longwood Eye & LASIK Center
Parents are usually well-versed in vaccination schedules and pediatrician visits, but many don’t realize how important early eye exams are for their children. Poor vision can hold kids back in school, and some childhood eye conditions can cause permanent vision problems if not caught early.
When Should Your Child Have an Eye Exam?
- First exam at 6 months: Infants should have their first comprehensive eye exam at six months of age
- Second exam at age 3: This checks for common childhood eye problems like lazy eye (amblyopia)
- Before starting school: Around age 5 or 6, just before entering kindergarten or first grade
- School-age children: Every one to two years to monitor vision changes and prescription needs
Catching vision problems early gives your child the best chance for normal visual development and academic success.
How Often Do You Need an Eye Exam?
If you haven’t noticed any changes in your vision, you might think you don’t need an eye exam. But here’s the problem: conditions like glaucoma can steal your sight silently, especially after age 40. Waiting until you notice a problem could mean it’s already too late.
If you don’t have vision problems, here are some general recommendations:
- Ages 20-39: Every 5-10 years
- Ages 40-54: Every 2-4 years
- Ages 55-64: Every 1-3 years
- Age 65 and older: Every year
However, you should be examined more often if you:
- Wear glasses or contact lenses
- Have a family history of eye disease
- Have a chronic condition that affects your eyes, like diabetes
- Take medications that have vision-related side effects
- Have had eye surgery or injury
How Do I Know if I Need Glasses?
During your comprehensive exam, our refraction assessment will tell us exactly how your vision compares to perfect 20/20 vision. Based on this test, we can determine if you’re:
- Nearsighted (myopic): You see close objects clearly but struggle with distance vision
- Farsighted (hyperopic): You see distant objects better than up-close objects
- Have astigmatism: Your cornea is shaped more like a football than a basketball, causing blurred vision at all distances
If you need vision correction, we’ll provide a prescription that specifies exactly what correction you need. During the phoropter test, we’ll flip between different lens options while asking “Which is clearer — one or two?” This precise process ensures your prescription is perfectly suited to your eyes.
What Eye Conditions Can Be Detected During a Routine Eye Exam?
One of the most important reasons for regular comprehensive eye exams is disease detection. We screen for every possible eye condition, including:
- Cataracts
- Glaucoma
- Macular degeneration
- Diabetic retinopathy
- Retinal detachment
- Corneal diseases
- Dry eye syndrome
Here’s why this matters: most of these conditions don’t show early symptoms. You could have glaucoma or macular degeneration developing right now and not know it until you’ve already lost significant vision. Regular exams allow us to catch these problems early when treatment is most effective.

Frequently Asked Questions
What should I bring to my eye exam?
Bring your current glasses or contact lenses, a list of any medications you’re taking, your insurance card, and information about any family history of eye disease. If you wear contacts, bring your contact lens prescription or the boxes they came in.
How long does a comprehensive eye exam take?
Plan for about 45 minutes to an hour for a comprehensive exam. If we need to dilate your pupils, you may need a bit more time, and your vision will be blurry for several hours afterward.
Will my eyes be dilated?
In most cases, yes. Dilation gives us the best view of the back of your eye, allowing us to check for signs of serious conditions like macular degeneration, diabetic retinopathy, and glaucoma. Your pupils will be enlarged for 2-4 hours, making you sensitive to light and affecting your ability to focus on close objects. We recommend bringing sunglasses and having someone drive you home.
Can I wear my contact lenses to my exam?
Yes, you can wear your contacts to your appointment. However, if you’re getting a new contact lens prescription, we may ask you to remove them so we can examine your eyes and get accurate measurements.
What’s the difference between an optometrist and an ophthalmologist? Optometrists are eye care professionals who examine eyes, prescribe glasses and contacts, and detect eye diseases. Ophthalmologists are medical doctors who can do everything an optometrist does, plus perform eye surgery and treat complex eye diseases. At Longwood Eye & LASIK Center, our team includes both, ensuring you get comprehensive care no matter what your eyes need.
I don’t have any vision problems. Do I really need regular eye exams? Absolutely. Many serious eye diseases have no early symptoms. By the time you notice something’s wrong, permanent damage may have already occurred. Regular exams catch problems early when they’re most treatable. Plus, your eyes can reveal signs of other health problems like diabetes, high blood pressure, and even brain tumors.
My child seems to see fine. Why do they need an eye exam?
Children are amazingly adaptable and often don’t realize they have vision problems. They might think everyone sees the way they do. Poor vision can significantly impact learning and development, and some childhood eye conditions need early treatment to prevent permanent vision loss. An exam is the only way to know for sure that your child’s eyes are healthy and developing normally.
Does insurance cover eye exams?
Most insurance plans cover comprehensive eye exams as preventive care, especially if you’re at risk for eye diseases. However, coverage varies widely between plans. Contact your insurance provider or our office, and we’ll help you understand your benefits.
What if I need glasses? Can I get them the same day?
While we can provide your prescription immediately after your exam, most people don’t receive their glasses the same day. If you order glasses from our optical shop, they typically take 7-10 days to arrive, depending on your prescription and lens options. We’ll let you know the expected timeline when you order.
