A practical checklist covering the questions to ask, the checks your eye care provider will run, and habits to establish from day one.

Key Takeaways

A contact lens fitting is a separate appointment from a routine eye exam and involves additional measurements.
Sharing your full medical history, medications, and lifestyle details helps your provider choose the right lens type.
Most first-time wearers spend time in-office practicing insertion, removal, and basic care before leaving.
Wearing contacts before your fitting appointment can temporarily alter corneal shape and skew measurements.
Follow-up visits are a standard part of any contact lens fitting and should not be skipped.

Why a Contact Lens Fitting Is More Than a Regular Eye Exam

If you already wear glasses, you might assume your existing prescription is all you need to order contact lenses. In practice, a contact lens fitting is a distinct clinical appointment that goes well beyond refraction. Your eye care provider will measure the curvature and diameter of your cornea, assess your tear film, and evaluate how a trial lens actually sits on your eye. These steps determine the correct BC and lens diameter — numbers that do not appear on a glasses prescription.

Understanding what happens during a fitting helps you arrive prepared, ask the right questions, and start wearing lenses safely. If you are still weighing whether contacts are right for you at all, our comparison of glasses and contact lenses can help you think through comfort, cost, and lifestyle fit before you commit.

Before the Appointment

Stop wearing soft contact lenses for at least 24–48 hours before the fitting, or rigid lenses for longer as advised, so corneal measurements are accurate. Must

Compile a list of all current medications, including eye drops and antihistamines, since some affect tear production and lens tolerance. Must

Note any history of dry eye, allergies, or previous eye conditions and be ready to share these with your provider. Must

Bring your current glasses to the appointment so the provider can reference your existing prescription as a baseline. Should

Think about your typical daily activities — screen time, outdoor exposure, sports — so your provider can recommend a lens material and wearing schedule suited to your lifestyle. Should

Write down any questions you have in advance so you do not forget them during the appointment. Nice to have

During the Fitting

Confirm that the provider is performing corneal curvature measurement (keratometry) and not relying solely on your glasses prescription. Must

Ask your provider to explain each lens type being considered — daily disposable, bi-weekly, monthly, or specialty lenses — so you understand the tradeoffs. Must

Disclose any symptoms such as dryness, redness, or sensitivity to light, even if they seem minor. Must

Practice inserting and removing the trial lens in the office until you feel reasonably confident; do not leave without completing this step. Must

Ask for a written or printed copy of your contact lens prescription, including base curve, diameter, power, and brand of trial lens. Should

Request a demonstration of proper lens care — solution use, case cleaning, and replacement schedule — before leaving. Should

Questions to Ask Your Provider

Ask how long you should wear trial lenses each day initially and when you can build up to full-day wear. Must

Clarify which symptoms should prompt you to remove the lenses immediately and when to call the office. Must

Ask whether your tear film or corneal shape makes you a candidate for specialty lenses such as toric (for astigmatism) or multifocal designs. Should

Confirm how many follow-up visits are included in the fitting process and what will be evaluated at each one. Should

Ask about sleeping or napping in lenses and whether the lens type you are trying is approved for extended wear. Nice to have

After the Fitting: First Two Weeks

Keep a simple daily log noting hours worn, any discomfort, redness, or blurry vision to share at your follow-up visit. Should

Attend the scheduled follow-up appointment even if your lenses feel comfortable, as the provider needs to assess corneal health with a slit lamp. Must

Avoid wearing trial lenses in water — including showers, pools, and hot tubs — until your provider confirms the lens type is appropriate. Must

Tools and Information Your Provider Will Use

Your eye care provider will use a combination of instruments and clinical judgment during the fitting. Knowing what they are can reduce any anxiety on the day.

Required

Keratometer or Corneal Topographer

Measures the curvature of your cornea to determine the correct base curve and diameter for your lenses.

Required

Slit Lamp Biomicroscope

Allows the provider to examine how a trial lens sits on the eye and assess corneal and conjunctival health.

Required

Phoropter or Trial Lens Set

Used to refine your contact lens power, which may differ slightly from your glasses prescription.

Required

Tear Film Assessment Tools

Evaluates tear quantity and quality to determine whether dry eye may affect lens comfort or suitability.

Required

Trial Contact Lenses

Diagnostic lenses placed on the eye during the appointment to evaluate fit, comfort, and vision before a final prescription is issued.

Optional

Contact Lens Care Kit (starter)

Includes multipurpose solution and a lens case; often provided or recommended by the office so you can practice proper hygiene from day one.

Common Pitfalls to Avoid Before and After Your Fitting

Do Not Wear Contacts Before Your Fitting

Soft contact lenses can temporarily reshape the cornea, causing measurements taken at your fitting to be inaccurate. Rigid gas-permeable lenses require an even longer break before the appointment — often several weeks. Ask your provider exactly how long to go lens-free before your visit and follow that guidance precisely.

Tap Water and Contact Lenses Do Not Mix

Rinsing lenses or your lens case with tap water introduces microorganisms — including Acanthamoeba — that can cause a serious corneal infection. Use only sterile, purpose-made contact lens solution for all rinsing and storage, and replace your lens case at least every three months.

Once you leave the office with trial lenses, safe daily habits become your responsibility. Our guide on caring for contact lenses safely walks through cleaning routines, storage, and wearing schedules that protect your eyes long-term. For a broader checklist of what to bring and disclose at any eye appointment, see before your eye appointment.

Remove Lenses Immediately If These Symptoms Occur

Sudden eye pain, significant redness, unusual discharge, or a noticeable drop in vision are signals to remove your lenses right away and contact your eye care provider. Do not wait to see if symptoms resolve on their own. These signs can indicate an early infection or corneal injury that worsens rapidly without prompt attention.
