Contact lens fittings at 6 Chicago-area locations

A contact lens exam is different from a regular eye exam. Your doctor conducts additional tests to evaluate and measure your eyes for contact lens wear. Even patients who’ve been wearing contacts for years without problems need periodic fit evaluations from an eye doctor.

Contact lens exam cost factors

If you have vision insurance, your plan may cover part of the cost of your contact lens fitting. We offer free insurance benefits checks so you can avoid surprise out-of-pocket costs – just call or stop by.

What is a contact lens fitting?

A contact lens fitting includes the eye and vision tests you’re used to as part of a routine eye exam. It also includes special tests and measurements specific to contact lens wear. In addition to vision correction, the size and type of contact lenses are included in the prescription.

Your eye anatomy, overall health, history of contact lens wear and other factors determine which tests are needed. In general, contact lens fittings can include:

Corneal topography during contact lens fitting Corneal topography

Photokeratoscopy measures the transparent front surface of your eye (the cornea). Precise dimensions are needed to determine which contacts will fit you comfortably. This is a completely non-invasive procedure. Your eye doctor uses a computer-assisted diagnostic tool to create a 3D map of the curvature, shape and regularity of your cornea.

Biomicroscope used in contact lens exam Biomicroscopy

Slit lamp exam lets the doctor examine your eyes microscopically, to detect abnormalities or changes caused by contact lens wear. The slit lamp is a binocular microscope with an adjustable light so the doctor can focus on specific parts of your eyes. You may need eye drops to dilate your pupils, or eye drops with fluorescein dye to highlight any damage on the surface of your eye.

Measuring the pupil and iris in a contact lens fitting Pupil & iris measurement

Measurement is done by holding a gauge (typically a card or ruler) near your eye, or by using an automated instrument. The diameter of your pupil and iris determine what size contact lenses you need.

Evaluating the tear film during a contact lens exam Tear film evaluation

Evaluation determines whether your eyes produce enough tears to be able to wear contact lenses. Patients with low tear production may be able to wear contact lenses made for dry eyes, or may be advised to avoid contact lenses (in cases of extremely dry eyes).

Trial contacts & follow-up fittings

After the tests, your eye doctor will prescribe trial contact lenses and ask you to wear them for a few days before a follow-up exam. If this is your first time wearing contacts, you’ll be instructed on how to handle them properly to protect your eye health.

At your follow-up fitting, your doctor will conduct another exam to see how your eyes are adjusting, and to make sure the lenses aren’t putting your eye health at risk. Even if everything feels fine, poorly fitting lenses can lead to problems. Too small, and the lenses can restrict tear flow. Too big, and the lenses can shift around and harm the surface of your eye.

Some types of contacts (for example, contacts for patients with astigmatism) can take longer to find the right fit. Once both you and your doctor are happy with the way your contact lenses are fitting, your contact lens prescription is complete. You can order contacts in the store, or through our website.

How often do you need a contact lens exam?

Preparing for your contact lens fitting

Contact lens fittings typically take longer than regular eye exams, so allow a little extra time in your schedule.

  • If you already have prescription glasses or contacts, bring them to your appointment.
  • When scheduling your contact lens exam, ask us for a free vision insurance check. We’ll let you know what your plan covers so you can avoid surprise out-of-pocket costs.
  • If this will be your first contact lens fitting, or your first time with a new eye doctor, be prepared to answer questions about your medical history and lifestyle.
  • Write down questions or concerns you may have about contacts ahead of time, so you don’t forget to ask your doctor.
  • If you’re interested in colored contact lenses, take this opportunity to ask about your options. Even if you don’t need vision correction, you should always get colored contacts through an optometrist.

Frequently Asked Questions

Why do contact lens exams cost more than regular eye exams?

Contact lens eye exams cost more than regular eye exams because they involve more tests, measurements, and evaluations to ensure a proper fit and minimize risk of damage to your eyes.

Why can't I use my eyeglasses prescription for contact lenses?

Eyeglass and contact lens prescriptions have very different properties. Eyeglass lenses are positioned about 10-15 millimeters from your eye, while contact lenses are directly on the eye’s surface. In addition to lens power and magnifying power, contact lens prescriptions include individual eye measurements (base curve and diameter) and a specific lens brand or material.

What are medically necessary contact lenses?

Contact lenses are considered medically necessary when the patient has a medical condition that prevents vision correction through prescription eyeglasses. Contacts can also be medically necessary to address specific conditions such as high ametropia or keratoconus.

The reason for medically necessary contact lenses is because most insurance providers won’t cover “elective” contact lenses. The definition of “medically necessary” can vary based on the type of vision insurance you have. We provide free coverage checks so you can understand what your plan covers.
