What is the Purpose of a Contact Lens Exam?

Thinking about trying contact lenses or updating your current pair? It’s not as simple as swapping out your glasses prescription. A contact lens exam is a key part of the process - designed specifically to ensure your lenses fit well, feel comfortable, and support long-term eye health. At Central DuPage Vision Center, we take the time to perform a thorough exam so you can enjoy all the benefits of contact lenses.

Understanding a Contact Lens Exam

A contact lens exam is a specialized evaluation that ensures your lenses fit properly and correct your vision safely and effectively. While a comprehensive eye exam checks your overall eye health and vision needs, a contact lens exam goes a step further to assess whether contacts are suitable for your eyes and lifestyle.

Key Components of a Contact Lens Exam

• Vision Assessment: Just like a standard eye exam, your optometrist will measure your visual acuity and determine your prescription. However, contact lens prescriptions include additional parameters such as base curve and diameter, which are critical for a proper fit.

• Corneal Measurement: Using instruments like a keratometer or corneal topographer, we measure the curvature of your cornea. These readings help determine the right lens shape and size, ensuring comfort and stability throughout the day.

• Tear Film Evaluation: A healthy tear film is essential for comfortable contact lens wear. We assess tear quantity and quality to determine whether your eyes can tolerate contacts or if treatment is needed for dry eye before lens use.

• Lens Fitting and Trial: We’ll fit you with trial lenses based on your measurements and visual needs. After applying the lenses, we assess how they align with your eye, how well they move with your blink, and how clearly you see.

• Follow-Up and Final Prescription: After wearing the trial lenses for a short period, we’ll schedule a follow-up to evaluate comfort and vision. If necessary, we make adjustments before finalizing your prescription and recommending lens types (daily disposables, monthly lenses, toric lenses for astigmatism, etc.).

Why Contact Lens Exams Matter

Improperly fitted lenses can lead to eye strain, blurry vision, or even more serious issues like corneal ulcers and infections. A contact lens exam helps prevent complications and ensures you get the most comfortable and effective solution for your vision.
