Contact lenses give a convenient way to correct vision for various lifestyles and activities. If you want to wear lenses, you must schedule a specialized exam with your eye care professional. Contacts are medical devices that sit directly on the eye surface. Because of this, they require a specific prescription that is different from a glasses prescription. During this visit, your doctor verifies that your eyes are healthy enough for lens wear and determines the best brand for your needs.
Difference Between Comprehensive Eye Exams And Contact Lens Exams
While these two appointments might seem similar, they serve different functions for your eye health. A comprehensive eye exam is significant for checking your general wellness and visual acuity. The doctor looks for signs of conditions like diabetes or high blood pressure that might impact your sight.
A contact lens exam involves additional tests to measure the surface of your eye. These tests determine if you are a candidate for lenses and what size you require. Note, a glasses prescription and a contact lens prescription are not interchangeable because the lenses sit at

What To Expect During Your Contact Lens Fitting
Your doctor will discuss your lifestyle and preferences to help select the right type of lens. You might choose between daily disposables or monthly replacement schedules based on your routine. The exam also covers several measurements of your eye anatomy.
- Cornea measurements using a keratometer to find the correct curvature
- Pupil and iris measurements to verify the lens covers the visual field
- Tear film evaluation to check for dry eye symptoms that might cause discomfort
- Evaluation of your blinking habits to see how the lens moves
If you are a first time wearer, the staff will teach you how to insert and remove the lenses safely. They also review the best ways to care for your lenses and storage cases. Note, you should never use tap water to clean your contacts because it contains harmful microorganisms.
Appointment Duration And Follow Up Visits
A contact lens exam frequently happens during the same visit as your standard eye checkup. The entire process usually takes about sixty minutes. If you are trying lenses for the first time, the appointment might last slightly longer to allow for training.
Your doctor might schedule a follow up visit one or two weeks later. This allows them to verify that the lenses remain comfortable and your vision stays clear during daily use. Once the fit is successful, the doctor will release your final prescription.
Evaluating The Cost Of An Exam
The cost of a contact lens exam varies based on your location and the complexity of your prescription. Most exams fall within the range of one hundred to two hundred fifty dollars. Many vision insurance plans cover a portion of this fee or require a simple copay. You should contact your insurance carrier to verify your specific coverage levels. If you do not have insurance, you will likely pay the full amount at the time of the visit.
Frequency Of Contact Lens Prescription Renewals
Most contact lens prescriptions expire after twelve months. This means you should visit your eye care provider annually to check your eye health and update your vision needs. Regular visits are a significant way to catch changes in your vision early. If you experience redness or blurry sight between visits, you should contact your doctor immediately. Using an online vision test can also help you renew your prescription if your eye health is stable and you simply need a fresh order.
