A regular (comprehensive) eye exam checks your eye health and determines your glasses prescription. A contact lens exam adds fitting work — corneal measurements, tear-film evaluation, trial lenses, and follow-up — to prescribe a lens that physically fits your eye. It is separate clinical work with a separate fee, because a contact lens prescription is not a glasses prescription. Here is what each exam includes, why they are billed separately, and what you can expect to pay.
What the Comprehensive Eye Exam Covers
Every patient starts with a comprehensive eye exam, whether they wear glasses, contacts, or nothing at all. This exam evaluates the internal health of your eyes — checking for glaucoma, cataracts, macular degeneration, diabetic changes, and other conditions. It also measures your refractive error (nearsightedness, farsightedness, astigmatism) to determine a glasses prescription.
What the comprehensive exam cannot tell you is which contact lens brand, size, and curvature fits your specific cornea. Your glasses prescription describes how light needs to bend to reach your retina. A contact lens sits directly on the eye, so it needs additional physical measurements that a glasses Rx does not include.
What the Contact Lens Fitting Adds
The fitting exam is the clinical work that bridges the gap between a glasses prescription and a wearable contact lens. It typically includes:
- Corneal topography and measurements — mapping the curvature, diameter, and shape of the front surface of your eye so the lens matches your anatomy
- Tear-film evaluation — assessing tear volume and quality, which determines which lens material will stay comfortable throughout the day
- Trial lens selection — choosing a lens brand, base curve, and power based on your measurements, then placing it on the eye to evaluate movement, centering, and comfort
- Insertion and removal training — for new wearers, hands-on instruction until you can handle the lenses independently
- Follow-up visit — a return check (usually one to two weeks later) to confirm the fit, assess corneal health, and finalize the prescription
Each of these steps requires clinical time, specialized equipment, and professional judgment. The fitting is where your doctor determines not just what power you need, but which specific lens design will work on your eyes.
Why Two Separate Fees
The comprehensive exam and the contact lens fitting are two distinct clinical services. They involve different equipment, different measurements, different professional liability, and different time commitments. Billing them separately is standard across the industry — not an added charge unique to any one office.
A glasses prescription gives you a power and an axis. A contact lens prescription adds base curve, diameter, brand name, replacement schedule, and wear modality (daily, biweekly, monthly, extended). These are legally separate prescriptions: a retailer cannot fill a contact lens order using a glasses Rx, and vice versa.
For context on how insurance interacts with these two fees, see our guide to vision vs. medical insurance — vision plans typically cover part of the fitting through a contact lens allowance.
What Fittings Cost Here
Fitting fees depend on lens complexity. At our office:
- Non-specialty fittings (standard soft lenses — daily, biweekly, or monthly disposables): $200–$600
- Specialty fittings (scleral lenses, keratoconus lenses, ortho-k, hard-to-fit cases): $1,200–$4,000
Specialty fittings cost more because they involve custom lens designs, more trial sets, additional follow-up visits, and advanced imaging. A standard soft lens fitting may take one or two visits. A scleral lens fitting for keratoconus can take three to five visits over several weeks to optimize.

When Standard Lenses Are Not Enough
If you have tried soft contact lenses before and found them uncomfortable, unstable, or unable to correct your vision clearly, you may be a candidate for specialty contact lenses. Common reasons for a specialty fitting include:
- Keratoconus or corneal irregularity — standard lenses cannot conform to an irregular cornea; scleral lenses vault over the entire cornea for stable vision and comfort
- High astigmatism — toric soft lenses may rotate or blur; rigid or hybrid designs hold axis more precisely
- Presbyopia — multifocal contact lenses or monovision setups can reduce dependence on reading glasses
- Chronic dry eye — scleral lenses hold a fluid reservoir against the cornea, providing constant hydration
Dr. Bonakdar fits specialty lenses for patients across Orange County, including many referred from other practices after standard options failed. If soft lenses have not worked for you, that does not mean contacts are off the table.
How Often You Need Each Exam, and Insurance
A comprehensive eye exam is recommended annually for most adults. If you wear contact lenses, the fitting portion is also renewed annually — your contact lens prescription expires each year by regulation, and the renewal exam checks for complications like corneal oxygen deprivation, surface dryness, or subtle fit changes.
Vision insurance plans (VSP, EyeMed, and others) typically cover the comprehensive exam and provide a contact lens allowance that partially offsets the fitting fee. The allowance amount varies by plan. For questions about what your specific plan covers, see our insurance page or call the office before your appointment.

Frequently Asked Questions
Why do I pay a separate fitting fee for contacts?
A contact lens fitting is a separate clinical service from the eye exam. It includes corneal measurements, tear-film evaluation, trial lens selection, insertion and removal training, and follow-up visits to confirm fit and comfort. These steps require additional chair time, equipment, and professional liability beyond what a glasses prescription involves.
Can I use my glasses prescription to buy contacts?
No. A contact lens prescription is legally distinct from a glasses prescription. Contact Rx includes additional fitted parameters — base curve, diameter, brand, and wear schedule — that must be determined by a fitting exam. Retailers cannot legally fill a contact order with only a glasses Rx.
How much does a contact lens exam cost?
Non-specialty contact lens fittings (standard soft lenses) range from $200 to $600. Specialty fittings — scleral lenses, keratoconus lenses, ortho-k, or hard-to-fit cases — range from $1,200 to $4,000 depending on complexity. Vision insurance may offset part of the cost through a contact lens allowance.
Do I need a new contact lens exam every year?
Yes. A contact lens prescription expires annually by regulation. The yearly exam checks for complications that can develop silently — corneal changes, dry eye, or oxygen deprivation from lens wear. Skipping the annual fitting puts your eye health at risk and means your prescription cannot legally be filled.
What if regular soft lenses never worked for me?
Hard-to-fit does not mean impossible. Patients with astigmatism, presbyopia, dry eye, or irregular corneas (including keratoconus) often succeed with specialty options — toric soft lenses, multifocal designs, hybrid lenses, or scleral lenses. A specialty fitting evaluates which design matches your corneal shape and tear film.
