Annual Contact Lens Eye Exams
Why a Yearly Contact Lens Exam Matters
Contact lenses interact with your eyes every single day, which means small changes can build quietly over time. A yearly exam gives your Eye Doctor the opportunity to catch those changes early, before they become harder to address.
Some of the most important findings in an eye exam have no obvious symptoms. A yearly visit screens for early glaucoma, diabetic retinopathy, and corneal blood vessel growth that can develop from lens overwear. These conditions can threaten your vision before you feel or notice anything unusual. Skipping a year allows small problems to develop into larger ones that take longer to correct.
Contact lenses sit directly on the cornea, the clear dome at the front of your eye, and share space with your tear film, the thin layer of moisture that keeps the eye comfortable. Daily wear gradually affects how the tear film spreads and can create subtle surface changes on the cornea that you cannot feel. A yearly check identifies early signs of dryness, surface stippling, or corneal thinning before they become significant. Catching these signs early often means a simple lens adjustment rather than a forced break from contacts altogether.
Refraction, the measurement of how your eye focuses light, changes slowly over time. A small shift in power can leave you squinting without a clear reason why. The physical fit of your lens can also change as the eye ages and the shape of the eyelids adjusts. Your annual exam confirms the lens power is still correct and that the base curve, diameter, and brand still match your cornea properly. An outdated prescription is not just inconvenient; it can also mean wearing lenses that do not sit or perform the way they should.
A yearly appointment is a natural opportunity to review the parts of your contact lens routine that can quietly fall behind. Your Eye Doctor can walk through cleaning steps with you and identify any gaps. Replacing your contact lens storage case at least every three months is an important habit that reduces buildup and lowers the risk of infection. Your annual visit is a useful reminder to refresh your case, restock solution, and confirm your routine is still working well.
What Happens During a Contact Lens Exam
A contact lens exam covers more ground than a standard glasses prescription check. It combines a full eye health evaluation with a detailed assessment of how lenses interact with your specific eyes, giving your Eye Doctor a complete picture of your ocular health and your lens fit.
Before any lens work begins, your Eye Doctor checks the overall health of both eyes. This includes the front surface of the eye, internal eye pressure, and the structures at the back of the eye. A dilated exam looks at the retina, optic nerve, and crystalline lens and can reveal conditions that a routine vision check would miss. Your Eye Doctor will decide how often dilation is needed based on your age, personal health history, and overall risk factors. Plan to bring a pair of sunglasses to your appointment because your eyes will be light-sensitive for a few hours afterward.
Refraction is the step most patients recognize. You look through a series of lens choices and identify which ones look clearer. Your Eye Doctor combines those responses with objective measurements from specialized instruments to determine your current prescription power. For contact lens wearers, the contact lens power is often slightly different from a glasses prescription because the lens rests directly on the eye rather than at a distance in a frame.
A complete contact lens exam goes well beyond updating your power. Your Eye Doctor measures the shape of your cornea, evaluates tear-film quality, and observes how the lens centers and moves with each blink. A fluorescein dye pattern can show exactly how the lens rests against the cornea and whether the fit is correct. A lens that feels comfortable to you may still be sitting too tight or riding too high, which can trigger irritation, redness, or corneal changes over time if left uncorrected.
A contact lens prescription is not the same as a glasses prescription. It includes the base curve, diameter, brand, material, and power specific to your eyes. Federal rules require your Eye Doctor to provide you with a copy of your prescription after the fitting is complete. This allows you to purchase lenses from any verified seller. Keep your prescription somewhere accessible because most retailers will ask for it with each new order.
Specialty Contact Lens Fittings at Our Practice
Not every patient is well served by standard soft lenses. Our optometry team includes specialists with deep experience fitting complex and specialty lenses for patients who need a more individualized approach, including those with challenging prescriptions or corneal conditions.
Our optometry team brings a high level of specialty lens expertise to every fitting. Dr. Paul Zerbinopoulos has been fitting scleral lenses since 2008 and is a past president of the Rhode Island Optometric Association. Dr. Earle Scharff brings four decades of experience fitting rigid gas-permeable, multifocal, toric, and scleral lenses. Dr. Lori Boivin has a background in specialty lens fittings from her training at Massachusetts Eye and Ear. Together, they manage some of the most complex contact lens cases in the region.
Several conditions make standard soft lenses difficult or ineffective. Our team fits patients with keratoconus, a condition where the cornea progressively thins and bulges forward, as well as post-surgical corneal irregularities, severe dry eye, and high prescriptions that are hard to correct with conventional lenses. We also fit pediatric patients with aphakia, a condition where the natural lens of the eye is absent, which requires a very specific lens approach.
- Keratoconus and post-surgical ectasia
- Irregular corneas from injury or prior surgery
- Severe dry eye requiring scleral lens support
- High prescriptions including high myopia and astigmatism
- Pediatric aphakia
We offer a full range of contact lens options to match each patient's vision needs, corneal anatomy, and lifestyle. Your Eye Doctor will recommend the lens type that offers the best combination of clarity, comfort, and corneal health for your specific situation.
- Scleral lenses for irregular corneas and dry eye
- Rigid gas-permeable lenses for high prescriptions and irregular corneas
- Toric lenses for astigmatism correction
- Multifocal lenses for patients who need correction at multiple distances
- Orthokeratology and myopia-control lenses for eligible patients
- Daily and monthly soft lenses for routine wear
When to Book and What to Do Between Visits
Timing your annual exam correctly helps you avoid gaps in your lens supply and keeps your corneal health on a consistent schedule. A few simple habits between visits can also make a meaningful difference in what your Eye Doctor finds at your next appointment.
Contact lens prescription expiration dates are set by state law. Where no specific state rule applies, federal law sets a default one-year expiration unless your Eye Doctor documents a medical reason for a shorter window. Check the expiration date on your current prescription and book your appointment about one month before it expires. That buffer gives you time to schedule, complete the exam, and receive your new prescription before your supply runs out.
Certain symptoms should not wait for your yearly visit. Red eyes that do not clear after removing your lenses, new pain, light sensitivity, blurry vision that persists after rinsing your eyes, or any discharge are all reasons to contact us promptly. A sudden change in how a lens feels on the eye also warrants an evaluation. Small problems found early are nearly always easier to treat than those that have had time to develop.
At the end of a complete annual contact lens exam, you receive a fresh written prescription with all the specifications needed to order your lenses from any verified retailer. You also leave with a confirmed lens type and replacement schedule, along with any specific guidance your Eye Doctor wants you to follow over the next year. If a trial lens goes home with you that day, consider it a fit check rather than a final prescription. The prescription becomes official only once your Eye Doctor has confirmed the lens works well for you over a short wear period.
What you do in between your annual appointments directly affects what the next exam finds. Wear your lenses only for the schedule your Eye Doctor recommended and replace them exactly on time rather than stretching a pair for extra days. Replace your storage case every three months and use only the solution your Eye Doctor approved. These consistent habits reduce infection risk and help keep your next fitting straightforward.
Frequently Asked Questions
Here are answers to questions patients commonly ask about their annual contact lens exams, including guidance on timing, preparation, and when to seek care sooner.
Online refraction tools can estimate a change in your glasses power, but they are not a substitute for a contact lens exam. They cannot evaluate your corneal health, check your tear film, assess lens fit, or screen for conditions like early glaucoma. They also do not meet the legal standard required to issue or renew a contact lens prescription. Use online tools only as a general reference between visits, and plan to complete a full in-person exam before ordering new lenses.
Once your prescription expires, you should stop placing new lens orders because most retailers and pharmacies are legally required to decline expired prescriptions. Book your exam as soon as possible and switch to your backup glasses in the meantime. Avoid wearing your last pair of contacts past their intended replacement date to bridge the gap. Overworn lenses are among the most common causes of contact-related eye infections, and a tired pair is not worth the risk.
Yes. The changes that occur in the cornea and tear film over time are not solely a function of how many hours a day you wear lenses. They accumulate with time regardless of wear frequency. Part-time wearers sometimes assume they can safely extend the interval between exams, but an annual visit is still the recommended standard. Your Eye Doctor also uses the visit to check your overall eye health, which is important for everyone, not just full-time wearers.
Wearing your current lenses to the appointment is helpful whenever possible. Your Eye Doctor can observe how the lenses actually fit your eyes after a typical period of wear, which provides more useful information than examining a fresh lens straight from the package. If you cannot wear them in, bring the box and a spare pair in their case. Bringing your current solution along is also a good idea so your Eye Doctor can confirm your care routine is compatible with your lens type.
Yes, several systemic health changes can affect how your eyes respond to contact lenses. Pregnancy causes hormonal shifts that can alter corneal thickness and tear production. Conditions such as diabetes, thyroid disease, and autoimmune disorders can also change how the eye tolerates lenses over time. Let your Eye Doctor know about any new diagnoses, medications, or pregnancy at the start of your visit. Depending on what has changed, you may need a follow-up appointment sooner than twelve months to reassess your fit once your condition has stabilized.
A routine eye exam focuses on overall eye health and determines your glasses prescription. A contact lens exam includes those same components and then adds several additional steps: measuring your corneal shape, evaluating how a specific lens sits and moves on your eye, and confirming that the lens brand and material are still the right choice for you. Because of these added steps, a contact lens exam typically takes a little longer than a standard visit and may include a separate fitting fee.
