Contact Lens Fitting

Contact Lens Fitting in Chinook

Contact lenses are not one-size-fits-all. Your eyes have a unique shape, curvature, and tear film composition that determine which lens design will give you the clearest, most comfortable vision. A proper contact lens fitting ensures that the lenses you wear are matched to your specific anatomy and your daily demands, not just your prescription.

At Chinook Eye Center, Dr. Perez takes the time to measure, test, and evaluate your contact lens fit with the same precision he brings to every part of your eye care. Whether you are a long-time contact lens wearer looking for a better option or trying contacts for the first time, we make the process comfortable and straightforward.

What Happens During a Contact Lens Fitting

Every contact lens fitting begins with a full eye health evaluation. Dr. Perez needs to confirm that your eyes are healthy enough for contact lens wear and that there are no underlying conditions, such as significant dry eye or corneal irregularities, that need to be addressed first.

Using both manual and computerized instruments, Dr. Perez measures the curvature and diameter of your cornea. These measurements determine the base curve and diameter of your contact lenses. A lens that does not match your corneal shape will move too much, sit too tight, or create discomfort and blurred vision.

Your tear production and tear film quality are evaluated. Contacts sit on your tear film, and inadequate moisture is the most common reason people struggle with lens comfort. In Montana’s dry, windy climate, this assessment is especially important.

Based on your measurements, prescription, and lifestyle, Dr. Perez selects trial lenses for you to wear. You will try the lenses on in the office so Dr. Perez can evaluate the fit, movement, and centration under the slit lamp before you leave.

After wearing the trial lenses for a period, you return for a follow-up so Dr. Perez can confirm the fit remains optimal and your vision is stable. Adjustments are made if needed.

Contact Lens Options

We fit a full range of contact lens types based on your needs:

A fresh pair every day, with no cleaning solutions, no storage cases, no buildup of deposits. Daily disposables are the healthiest contact lens option and ideal for patients with allergies, dry eye tendencies, or those who wear contacts only on certain days.
Replaced every 30 days with proper daily cleaning and overnight storage. A cost-effective option for full-time wearers with healthy tear film.

Designed to be worn continuously for up to a week or longer, depending on the lens. Dr. Perez will discuss whether extended wear is appropriate for your eye health.

Durable, long-lasting lenses that provide exceptionally sharp vision. RGP lenses are often recommended for patients with astigmatism or keratoconus who need optical correction that soft lenses cannot fully provide.

Specially designed soft lenses that correct astigmatism while maintaining rotational stability on the eye.

For patients over 40 experiencing presbyopia, the gradual loss of near-focus ability. Multifocal contacts reduce or eliminate the need for reading glasses.

Contact Lenses in Montana's Climate

Wind, dry air, dust, and UV exposure are facts of life on the Hi-Line. These conditions can make contact lens wear challenging if the wrong lens type is prescribed. Dr. Perez considers your environment and daily activities, whether you spend your days in an office, on a ranch, or behind the wheel on long rural drives, when recommending the lens that will perform best for you.

Your Prescription Is Yours

After your fitting is complete, you receive a one-year contact lens prescription that is valid for purchasing lenses anywhere , from us, from an online retailer, or from any other provider. We earn your business on the quality of our fitting, not by restricting where you buy your lenses.
