Do You Need Both a Routine Eye Exam and a Contact Lens Exam?

If you wear contact lenses or are thinking about trying them, you may wonder why your eye doctor recommends both a routine eye exam and a separate contact lens exam. Aren’t they the same thing? While they may happen during the same appointment, a routine comprehensive eye exam and a contact lens exam serve different purposes. Each plays an important role in protecting your vision and ensuring your eyes stay healthy and comfortable.

What Is a Routine Eye Exam?

A routine comprehensive eye exam focuses on your overall eye health and vision. Even if you see clearly, these exams are essential for detecting early signs of eye conditions and systemic health issues.

During a routine exam at Spotlight Optometry, your optometrist will:

• Evaluate your visual acuity (how clearly you see at different distances)
• Update your glasses prescription if needed
• Check eye coordination and focusing ability
• Examine the internal and external structures of your eyes
• Screen for eye diseases such as glaucoma, macular degeneration, and diabetic eye disease

This exam ensures your eyes are healthy and functioning properly. However, it does not include the specialized measurements and evaluations required for contact lenses.

What Is a Contact Lens Exam?

A contact lens exam goes beyond determining your prescription. Because contact lenses sit directly on the surface of your eye, they must be carefully fitted to ensure safety, comfort, and optimal vision.

A contact lens exam typically includes:

• Precise measurements of your cornea (the front surface of your eye)
• Evaluation of your tear film to ensure your eyes can support lens wear
• Assessment of your eye surface health
• Determination of the correct lens material and brand based on your lifestyle and needs
• Trial lenses to evaluate fit, movement, and comfort

Even if your glasses prescription hasn’t changed, your contact lens prescription may need adjustment. Contact lenses are medical devices regulated by the FDA and require a valid, up-to-date prescription.

Why Isn’t a Glasses Prescription Enough?

Glasses and contact lenses sit in different positions relative to your eye. Glasses rest about 12 millimeters away from the eye, while contact lenses sit directly on the cornea. Because of this difference, the power and curvature of contact lenses must be calculated differently.

Additionally, contact lenses vary in:

• Base curve (how steep or flat the lens is)
• Diameter
• Material (daily disposable, monthly, toric for astigmatism, multifocal, etc.)

Wearing improperly fitted lenses can lead to discomfort, blurry vision, dry eye symptoms, or even serious complications such as corneal infections.

Do You Need Both Every Year?

If you wear contact lenses, you typically need both a comprehensive eye exam and a contact lens exam annually. Your routine exam ensures your eyes remain healthy and free of disease. Your contact lens exam ensures your lenses continue to fit properly and safely.

Skipping the contact lens portion can mean:

• Wearing an outdated or incorrect prescription
• Increased risk of irritation or infection
• Reduced comfort or visual clarity

Even if your lenses feel fine, subtle changes in your cornea or tear film can occur over time. Regular evaluations help catch issues before they become bigger problems.
