What Is Included in a Contact Lens Exam? A Complete Guide From an Austin Optometrist

If you wear contacts — or you're thinking about switching from glasses — you've probably wondered why a "contact lens exam" is valued more and takes longer than a regular eye exam. It's a fair question, and the short answer is that contact lenses sit directly on your eye, so fitting them correctly requires a level of measurement and evaluation that glasses simply don't need.

This guide walks through exactly what's included in a comprehensive contact lens exam, why each step matters, and what to expect from a contact lens fitting at Resolution Eyecare, a locally owned optometry practice with studios in Highland, Tech Ridge, and Round Rock, serving patients across Austin, Georgetown, Brushy Creek, and Hutto.

Quick Answer: What Happens During a Contact Lens Exam

A contact lens exam includes everything in a comprehensive eye exam: vision testing, glaucoma screening, and overall eye health evaluation, plus contact-lens-specific steps: corneal curvature measurement, tear film and ocular surface evaluation, pupil and iris measurement, a trial lens fitting, and a follow-up check to confirm the lenses fit properly and vision is clear and comfortable. At Resolution Eyecare, this process also includes screening for dry eye disease, which is one of the most common reasons contact lens wearers quit lenses altogether.

Why a Contact Lens Exam Is Different From a Regular Eye Exam

A standard comprehensive eye exam determines your prescription and checks the overall health of your eyes. A contact lens exam builds on that foundation but adds an entirely separate layer of evaluation, because a contact lens is a medical device that rests directly on the surface of your eye. Getting the fit wrong doesn't just mean blurry vision. It can cause corneal abrasions, chronic dryness, infections, or long-term damage to the cornea if lenses are worn incorrectly for years.

That's why Texas, like most states, legally requires a separate, valid contact lens prescription in addition to a glasses prescription, and why an optometrist needs additional in-office measurements before writing one.

What's Included in a Comprehensive Contact Lens Exam

1. A Comprehensive Eye Exam

Every contact lens fitting starts with a full comprehensive eye exam: visual acuity testing, refraction, glaucoma screening, and a health evaluation of the retina, optic nerve, and anterior eye structures. This step confirms your eyes are healthy enough for contact lens wear and establishes your baseline glasses prescription.

2. Corneal Curvature Measurement (Keratometry)

Using an instrument called a keratometer or corneal topographer, your optometrist measures the exact curvature of your cornea. Contact lenses have to match this curve closely. Too flat or too steep, and the lens will either move too much or restrict oxygen and tear flow to the eye.

3. Pupil and Iris Size Measurement

The size of your pupil and iris helps determine the diameter of the contact lens you need, which affects both comfort and how well the lens centers on your eye, especially important for larger specialty lenses like scleral lenses.

4. Tear Film and Ocular Surface Evaluation

This step is where a lot of basic contact lens exams fall short, and where Resolution Eyecare puts extra emphasis. Since a contact lens sits directly on the tear film, an inadequate or unstable tear film is one of the top reasons people find contacts uncomfortable or eventually give up on them. This evaluation checks tear quality and quantity and screens for early signs of dry eye disease, which is highly treatable when caught early.

5. Contact Lens Type and Material Selection

Based on your prescription, corneal shape, lifestyle, and any dryness or sensitivity issues, your optometrist recommends a lens type and material. Options include:

• Soft daily, weekly, or monthly disposable lenses for standard vision correction

• Toric lenses for astigmatism

• Multifocal lenses for presbyopia (age-related close-up vision changes)

• Specialty scleral lenses, which vault over the entire cornea and are ideal for irregular corneas, keratoconus, or chronic dry eye

• Orthokeratology (ortho-K) lenses, worn overnight to reshape the cornea and correct vision without daytime lenses or glasses

6. Trial Lens Fitting

Rather than ordering lenses blind, your optometrist places trial lenses on your eyes to evaluate fit, movement, centering, and comfort in real time. This is especially important for toric, multifocal, and specialty lenses, which behave very differently from person to person.

7. Vision Assessment With Lenses In

With trial lenses in place, your optometrist re-checks visual acuity to confirm the prescription actually delivers clear vision through the lens — not just on paper.

8. Insertion and Removal Training (First-Time Wearers)

If you're new to contacts, most exams include hands-on training for safely inserting, removing, and caring for your lenses, along with a review of wear schedules and hygiene practices that prevent infection.

9. Follow-Up Visit

Because a trial fit doesn't always translate perfectly to full-time wear, a short follow-up visit, typically within one to two weeks, checks how your eyes are adapting, confirms the fit is still correct, and finalizes your contact lens prescription.

How Long Does a Contact Lens Exam Take?

Expect a comprehensive eye exam plus contact lens fitting to take longer than a standard eye exam alone, often 45 minutes to an hour for a routine soft lens fitting, and longer for specialty fittings like scleral lenses or ortho-K, which require more precise measurement and multiple trial lenses.

Why Dry Eye Screening Matters for Contact Lens Wearers

Dry eye disease and contact lens discomfort are closely linked, and it's one of the most common reasons people abandon contacts within the first year. A contact lens exam that skips a real tear film evaluation is essentially guessing at long-term comfort. At Resolution Eyecare, dry eye disease management is a core clinical focus: patients who struggle with dryness in contacts can be evaluated and treated with in-office options like IPL and RF therapy, low-level light therapy (LLLT), and meibomian gland expression, often making contact lens wear comfortable again without switching back to glasses full-time.

About Resolution Eyecare

Resolution Eyecare is a locally owned, family-operated optometry practice with three studios across the Austin area — Highland, Tech Ridge, and Round Rock — serving patients throughout Austin, Round Rock, Georgetown, Brushy Creek, and Hutto. The practice was built around a simple standard: thorough, technology-forward exams and fittings, not rushed appointments designed to move you through the door.

That shows up directly in how contact lens exams are handled: full tear film and dry eye evaluation as a standard part of every fitting, in-depth trial fittings for complex prescriptions, and follow-up care to make sure lenses are actually comfortable, not just technically correct.

Frequently Asked Questions About Contact Lens Exams

Is a contact lens exam different from a regular eye exam? Yes. A regular eye exam checks your vision and eye health and produces a glasses prescription. A contact lens exam includes all of that plus additional measurements — corneal curvature, pupil size, and tear film evaluation — needed to fit a lens that sits directly on the eye.

Why does a contact lens exam cost more than a regular eye exam? The additional measurements, trial lenses, fitting time, and follow-up visit all require extra chair time and diagnostic testing beyond a standard eye exam, which is why contact lens fittings are typically billed separately from routine eye exams.

Can I get contacts if I have astigmatism? Yes. Toric contact lenses are specifically designed to correct astigmatism, and your optometrist will determine the right lens design and fit during your contact lens exam.

What if contacts have always felt uncomfortable for me? Discomfort is often linked to an unstable tear film or undiagnosed dry eye disease rather than the lenses themselves. A thorough contact lens exam that includes tear film evaluation, like the ones offered at Resolution Eyecare, can identify the underlying cause and often make contact lens wear comfortable again.

How often do I need a new contact lens exam? Contact lens prescriptions typically need to be renewed annually, since your cornea's shape, tear film, and prescription can all change over time, and lenses need to be reassessed for continued safe fit.

Can children get fitted for contact lenses? Yes. Many children are excellent candidates for contact lenses, including ortho-K lenses used in myopia management to help slow the progression of nearsightedness.

Do you offer scleral lens fittings in Austin? Yes. Resolution Eyecare fits scleral lenses for patients with irregular corneas, keratoconus, or dry eye disease that makes standard contacts difficult to wear comfortably.
