Taking out your contact lenses before an eye exam helps us get accurate measurements and see your eyes clearly. Contact lenses sit directly on your cornea and can temporarily change its shape or hide signs of eye problems. Whether you need to remove your contacts depends on the type of exam and how long you have worn your lenses.
Contact lenses affect the shape of your cornea and can interfere with important measurements. Understanding how lenses change your eyes helps explain why we ask you to remove them for certain tests.
Your cornea is the clear, dome-shaped front surface of your eye. When you wear contact lenses, they gently press against the cornea throughout the day. This pressure can temporarily mold the cornea into a slightly different shape, similar to how a pillow leaves an impression on your face after you sleep.
These shape changes are usually small, but they can affect the measurements we take during your exam. Rigid gas permeable lenses cause more corneal reshaping than soft lenses, which is why we may ask you to remove them for a longer period before your visit. Once you stop wearing your contacts, your cornea gradually returns to its natural shape over several hours or days.
Several important tests work best when your eyes are completely free of contact lenses. We use specialized instruments to measure the curvature of your cornea, the length of your eye, and the exact power of your natural prescription.
Contact lenses can sometimes make it harder to evaluate the health of your eye surface accurately during your exam. Redness, swelling, or tiny blood vessels growing into your cornea may be covered by the lens or difficult to assess clearly.
Conditions like dry eye, allergic reactions, and corneal infections are harder to evaluate accurately when contacts are still in place. By examining your eyes without contacts, we can spot early warning signs and address problems before they become more serious.
Getting the right eyeglass prescription depends on measuring your eyes in their natural state. If you wear contacts to your exam and we test your vision with them in, the prescription we write for glasses may not match what your eyes actually need.
For contact lens follow-ups, we may check vision with lenses on first, then remove lenses if corneal measurements or ocular surface evaluation are needed. Even when you are primarily getting a contact lens prescription, we typically need to measure your eyes without lenses first during comprehensive exams. This baseline measurement tells us your starting point and helps us choose the correct contact lens parameters.
The type of eye exam you need determines when and how long you should be out of your contact lenses. Some exams require only brief removal time, while others need your eyes to be lens-free for days or even weeks.
During your yearly comprehensive eye exam, we check your overall eye health and update your prescription if needed. For the most accurate results, we typically ask you to be out of your contact lenses before you arrive.
If you wear soft contact lenses daily, removing them the night before or the morning of your appointment is usually enough. We will examine your eyes first thing, perform all necessary measurements, and then you can usually put your contacts back in before you leave.
When you are getting fit for new contact lenses or changing to a different type, we need to see your eyes both with and without contacts. The initial fitting appointment requires bare eyes so we can take baseline measurements of your corneal curvature and eye surface.
If you are experiencing eye pain, redness, discharge, or any unusual symptoms, you should remove your contact lenses immediately and leave them out until after your medical eye exam. Continuing to wear contacts when your eyes are irritated can make the problem worse or delay healing.
We need to examine your cornea and eye surface directly to diagnose the cause of your symptoms. Contact lenses can trap bacteria or irritants against your eye and obscure the signs we need to see. Always bring your most recently worn contacts to the appointment in their case, along with the solutions you used. Do not discard them before the visit, as we may need to examine the lenses and case.
Do not reinsert the lenses until you are cleared. If symptoms are severe, such as significant pain, light sensitivity, or reduced vision, contact us right away for same-day evaluation.
Advanced diagnostic tests like optical coherence tomography, corneal pachymetry, and wavefront analysis often require precise measurements of your eye structures. Contact lenses can interfere with these sensitive instruments and produce unreliable data when measuring the cornea and anterior segment.
Some imaging tests focus on the back of your eye and may tolerate contact lens wear in certain situations. However, many corneal and biometry measurements require a clear, unobstructed view of your eye surface in its natural state. Following the removal timeline we provide ensures the testing session is productive and does not need to be rescheduled.
If you are being evaluated for cataract surgery, LASIK, PRK, or other refractive procedures, accurate corneal measurements are critical for calculating the correct lens implant power or laser treatment plan. Contact lenses can alter the shape of your cornea, and these changes must fully resolve before we perform keratometry, corneal topography, or biometry measurements.
Discontinuation times for preoperative measurements are often longer than for routine eye exams. The exact timeline depends on your lens type, how long you have been wearing them, and how quickly your corneas return to a stable baseline. We may ask you to come in for serial measurements to confirm your corneal shape has stabilized before scheduling surgery.
Proper preparation makes your exam day smoother and more productive. The timing and technique for removing your contact lenses depend on the type of lenses you wear and the purpose of your visit.
Soft contact lenses require different removal times depending on the purpose of your exam. The timeline varies based on whether we are performing routine refraction, detailed corneal mapping, or preoperative measurements.
Our office will provide personalized instructions when you schedule your appointment.
Rigid gas permeable lenses, also called RGP or hard lenses, require much longer removal times than soft lenses. These lenses hold their shape firmly and can significantly mold your cornea while you wear them. The reshaping effect takes longer to reverse once you remove the lenses.
For routine exams, RGP wearers often need to be out of lenses for days to weeks. For preoperative planning or irregular cornea assessments, the timeline may extend further depending on the duration of wear, corneal stability, and the type of measurements needed.
Always bring a clean contact lens case filled with fresh solution to your appointment, even if you plan to remove your lenses at home. You may need to take them out in our office, or we might ask you to remove them partway through your visit.
Bring the contact lens care system you actually use, including peroxide neutralizing cases if applicable. Backup glasses are equally important. If we find an eye health issue that requires you to stay out of contacts for a while, you will need glasses to see clearly when you leave.
If you arrive wearing contacts and need to remove them at our office, ask our staff for a clean, private space with a mirror. Always wash and dry your hands thoroughly before touching your eyes or lenses. Remove your contacts gently, place them in your case with solution, and close the case securely.
Do not rinse lenses or cases with tap water, as this can introduce harmful microorganisms. Let our staff know immediately if you have any trouble removing your lenses. Forcing a stuck or dried-out contact lens can scratch your cornea. We can provide rewetting drops or other assistance to help the lens come out safely.
Sometimes your eyes will tell you that your contacts need to come out sooner than planned. Unusual discomfort, redness, light sensitivity, or blurred vision are all signals that something is wrong. If you notice any of these symptoms in the days leading up to your exam, remove your contacts right away and keep them out.
Understanding the exam process helps you know what to expect and why certain steps are necessary. We structure your visit to gather the most accurate information about your eye health and vision needs.
When you first arrive for your appointment, we may conduct a few preliminary tests while you are still wearing your contact lenses. These initial checks help us understand how well your current contacts are working and whether they are providing adequate vision.
We also observe how your contact lenses fit and move on your eyes during these early minutes. This assessment is valuable for identifying lens-related problems like poor centration, excessive movement, or tight fit. Once we complete these initial observations, we will ask you to remove your contacts so we can proceed with measurements that require bare eyes.
Evaluating your contact lens fit is an important part of maintaining healthy eyes. Even if your lenses feel comfortable, they may not be positioned correctly or may be causing subtle changes to your cornea. We use a specialized microscope called a slit lamp to examine how your lenses sit on your eyes and how they move when you blink.
A properly fitting contact lens should move slightly with each blink but remain centered over your cornea. Lenses that fit too tightly can restrict oxygen flow and cause corneal swelling, while lenses that fit too loosely may slip around and cause blurry vision.
Once your contacts are out, we perform the core measurements that require direct access to your eyes. These tests form the foundation of your eye care and help us write accurate prescriptions. We start with refraction, where you look through different lenses and tell us which ones make your vision clearest.
Most patients can reinsert their contact lenses shortly after the exam is complete. Once we finish all the measurements and examinations, we will let you know when it is safe to put your contacts back in, which is usually before you leave the office.
However, there are some situations where we may ask you to stay in glasses for a period of time after your exam. If we find signs of infection, inflammation, or corneal damage, your eyes need a break from contact lens wear to heal properly. We will provide clear instructions about when you can resume wearing contacts and may prescribe medicated eye drops to use during your recovery period.
Before your appointment, consider how you will get home if you need to remain in glasses. If your current glasses prescription is significantly outdated or you do not have glasses with you, your vision may be too blurry to drive safely. Some patients also have dilating drops during their exam, which makes driving difficult for several hours.
Planning ahead eliminates stress and keeps you safe. Bring a friend or family member who can drive you home, use a rideshare service, or schedule your appointment at a time when you can wait for the effects of dilation to wear off.
Certain situations require extra attention or modified preparation. Understanding these special circumstances helps you know when to reach out to our office for specific guidance.
Extended wear contact lenses are designed to be worn overnight for several days or even weeks at a time. If you use this type of lens, you should still remove them before your comprehensive eye exam. The removal timeline depends on whether you have soft or rigid extended wear lenses.
Continuous wear increases the risk of certain eye complications, making it even more important for us to examine your bare corneas thoroughly. We need to check for signs of oxygen deprivation, protein deposits, and corneal changes that can develop with extended wear.
Forgetting to remove your contacts before your exam is common and usually not a major problem. Let our staff know as soon as you arrive, and we will work with you to get the most accurate results possible. You can remove your contacts in our office, and we may adjust the order of your tests to allow your corneas time to settle.
In some cases, we may need to reschedule certain measurements for a different day if your contacts have significantly altered your corneal shape. This is especially true for rigid lens wearers or for patients who need precise corneal mapping.
Certain symptoms require urgent attention and immediate contact lens removal. Severe eye pain, significant redness, vision loss, or discharge that looks infected are all red flags that something is seriously wrong. Remove your contacts right away and call our office for guidance, even if you do not have a scheduled appointment.
Some patients find it helpful to gradually transition from contacts to glasses in the days before their eye exam. This approach allows your corneas to return to their natural shape slowly and can reduce the adjustment period.
If you normally wear contacts every day, switching to glasses exclusively for a few days before your exam ensures the most accurate measurements. This strategy works particularly well for people who experience discomfort or dryness with prolonged contact lens wear.
Yes, you can remove your contacts in our waiting room or exam room if needed. Ask our staff for a clean space with a sink and mirror, and make sure to bring your contact case and solution with you. Let us know when you arrive so we can allow extra time for your corneas to settle before we begin testing. Never rinse lenses or cases with tap water, as this introduces harmful organisms that can cause serious infections.
Your ability to drive safely depends on how strong your prescription is and whether you bring backup glasses. People with mild prescriptions may see well enough to drive, while those with stronger prescriptions should wear glasses or arrange alternate transportation. State laws require adequate vision for safe driving, so always plan ahead. If you need to stay in glasses longer than expected due to an eye health issue we discover, having transportation arranged in advance prevents stress and keeps you safe on the road.
Contacts that have been worn overnight sometimes become stuck to your cornea due to dryness. Do not try to force them out, as this can cause injury. Instead, use rewetting drops or sterile saline to lubricate your eyes generously, wait several minutes, and try again gently. If the lens still will not budge after repeated attempts with lubrication, call our office for help removing the lens and checking your cornea for damage.
Even for a straightforward glasses prescription update, removing your contacts beforehand gives the most accurate results. Your eyeglass prescription measures your eyes in their natural, uncorrected state, so contacts interfere with getting the right numbers. The precision of your prescription directly affects your daily comfort and visual clarity. An inaccurate prescription can lead to headaches, eye strain, and dissatisfaction with your new glasses, making proper preparation worthwhile.
Yes, our eye care team can remove your contact lenses if you are unable to do so yourself. This service is especially helpful for new contact lens wearers who are still learning removal techniques, patients with limited dexterity due to arthritis or other conditions, or anyone experiencing a stuck or uncomfortable lens. We have specialized instruments and numbing drops if needed to safely remove contacts without harming your eyes. Let us know you need assistance when you arrive, and we will take care of it during your visit.
