Contact Lens Exam vs. Eye Exam: What’s the Difference?

Understanding the difference between a contact lens exam and a comprehensive eye exam can help you make informed decisions about your vision care. While both exams are essential for maintaining healthy eyesight, they serve different purposes.

What Is a Comprehensive Eye Exam?

A comprehensive eye exam focuses on evaluating your overall eye health and determining your prescription for glasses or other vision correction. During this appointment, your optometrist checks how clearly you see at different distances and performs a refraction test to determine your most accurate glasses prescription.

Beyond vision clarity, the exam also assesses how well your eyes work together, how your eye muscles function, and the health of both the internal and external structures of your eyes. Your doctor will screen for common eye diseases such as glaucoma, macular degeneration, and diabetic retinopathy. Even if your vision feels normal, routine eye exams are critical because many eye conditions develop gradually and without noticeable symptoms.

What Is a Contact Lens Exam?

A contact lens exam includes everything performed in a comprehensive eye exam, but it goes a step further to ensure contact lenses fit safely and comfortably. Because contact lenses sit directly on the surface of your eye, precise measurements and evaluations are necessary.

During a contact lens exam, your optometrist measures the curvature and size of your cornea to determine the proper lens shape and fit. Your tear film is evaluated to make sure your eyes produce enough moisture to support comfortable lens wear. You’ll typically try on trial lenses so your doctor can assess how they move and settle on your eyes. This step ensures the lenses provide clear vision without causing irritation.

Your optometrist will also help determine the best type of lenses for your needs, whether that includes soft lenses, rigid gas permeable lenses, toric lenses for astigmatism, multifocal lenses, or daily disposables. In many cases, a follow-up visit is scheduled to confirm that your lenses continue to fit well and provide lasting comfort.

How Often Should You Schedule an Exam?

Most patients benefit from an annual eye exam, and contact lens wearers should also have their lenses evaluated each year. Even if your prescription hasn’t changed, your eyes can shift over time, and your lenses may need adjustment to maintain optimal comfort and clarity.

If you experience redness, dryness, blurred vision, or discomfort while wearing contacts, it’s important to schedule an appointment promptly rather than waiting for your next routine visit.
