Contact Lens Exam vs Regular Eye Exam: What's the Real Difference?
If you've ever wondered whether your regular eye exam counts as a contact lens exam, the short answer is no. They're related but distinct. A contact lens exam includes everything your regular eye exam covers, plus additional measurements and tests specific to fitting lenses directly on your cornea. At Vision Palace Optical on Avenue U, we perform both thoroughly, and they're not the same appointment.
Here's what you need to know about each one, and why the difference matters if you're switching from glasses or trying contacts for the first time in Brooklyn.
Regular Eye Exam: The Foundation
Your standard eye exam evaluates your overall vision and eye health. Dr. Shlivko or Dr. Sheyko will check your eye pressure, test your peripheral vision, examine your retina, and determine your prescription for glasses or distance correction. We also screen for eye diseases like glaucoma and evaluate the health of your retina and optic nerve.
This exam is thorough and critical for detecting conditions that may have no symptoms. But it assumes you'll be correcting your vision with glasses sitting a specific distance from your eyes.
Contact Lens Exam: More Measurements, More Precision
A contact lens exam includes your regular eye exam plus additional steps. According to the American Optometric Association, a contact lens exam involves corneal topography (mapping the shape and curvature of your cornea), measurement of your corneal diameter, and assessment of your tear film, the natural lubrication that keeps contacts comfortable.
We also fit you with trial lenses and evaluate how they sit on your eye, how your lids interact with them, and whether your tears adequately coat the lens material.
The contact lens prescription is also different from your glasses prescription. Your glasses sit about 12 millimeters from your eye; contacts sit directly on your cornea. That changes the power needed to correct your vision, especially if you have astigmatism or a stronger prescription.
Why the Differences Matter
If you wear glasses and switch to contacts, your prescription will change, sometimes noticeably. A glasses prescription of -4.00 doesn't translate directly to a -4.00 contact lens prescription. Ignoring this and wearing a contact lens with your glasses prescription can result in blurred or distorted vision, eye strain, or discomfort on Avenue U or anywhere else in Brooklyn.
Additionally, contacts require corneal health assessment. If you have dry eye, allergies, or corneal irregularities, certain contact lens materials or wearing schedules may work better than others, information your regular exam alone won't uncover.
What Happens During a Contact Lens Exam at Vision Palace Optical
We start with your regular thorough eye exam to rule out any contraindications (conditions that might make contact lenses unsuitable). Then we measure your corneal curvature using corneal topography, determine your corneal diameter, and evaluate your tear production and quality.
Next, we place trial lenses in your eyes and have you wear them for a few minutes while we assess comfort, visual acuity, and lens positioning. If adjustments are needed, a different curvature, diameter, or material, we try again. This hands-on fitting ensures the lenses you take home will work.
Do You Need a Separate Contact Lens Exam Every Time?
Not always. If you've been successfully wearing the same contact lenses for years and your eye prescription hasn't changed, you may only need a regular eye exam annually and a contact lens exam every two years, depending on your eye health and your lens type. However, VSP Vision Care notes that fitting requirements vary, so always ask us during your visit.
If you're new to contacts, switching materials (daily to monthly, for example), or experiencing discomfort, a contact lens exam is essential.
Frequently Asked Questions
Do I need a contact lens exam if I only wear glasses?
No. A regular eye exam is sufficient for glasses correction. A contact lens exam is only necessary if you're considering or currently wearing contact lenses.
Can my glasses prescription be used for contacts?
No. Your glasses and contact lens prescriptions are different because of how they sit on your eye. Using your glasses prescription for contacts can cause blurred vision, discomfort, or eye strain. Always get a proper contact lens exam before ordering lenses.
How often should I get a contact lens exam?
The American Academy of Ophthalmology recommends annual eye exams for contact lens wearers. If your prescription is stable and your eyes are healthy, your optometrist may extend it, but contact lens exams typically happen at least every one to two years.
What if I have dry eye or allergies? Can I still wear contacts?
Your doctor will evaluate your specific situation during your contact lens exam. Dry eye and allergies don't automatically disqualify you from contacts, certain lens materials, wearing schedules, and solutions can minimize discomfort. We'll discuss the best options for your eyes during your fitting at Vision Palace Optical on Avenue U.
What's the cost difference between a regular eye exam and a contact lens exam?
Pricing varies depending on your insurance plan and the specific fitting complexity. Coverage varies by plan. Call us or book through Zocdoc to verify your benefits before your visit.
When to Schedule Each Type of Exam
Schedule a regular eye exam if you wear glasses, want to monitor your eye health, or haven't had your eyes checked in a year. Schedule a contact lens exam if you're trying contacts for the first time, switching lens types or materials, experiencing discomfort with your current lenses, or your eye prescription has changed.
Many Brooklyn families we see on Avenue U split their needs: a regular exam annually for overall health, and a contact lens exam when they need new lenses or want to troubleshoot fit issues. That's a smart approach.
Both exams are important anchors of your eye health routine. Dr. Shlivko and Dr. Sheyko are experienced in fitting all types of contacts, daily disposables, monthly lenses, toric for astigmatism, and multifocal for presbyopia. We'll help you find what works for your eyes and your lifestyle.
