Are you planning on wearing contact lenses for the first time? Do you need a new contact lens prescription? Are your current contacts not as comfortable as you wish they were? Your eye doctor will perform a contact lens eye exam to ensure that your vision with contacts is clear, comfortable, and safe.

What Is a Contact Lens Exam?

If you wear or want to wear contact lenses, you'll need a contact lens exam in addition to your regular comprehensive eye exam. Special tests are performed during a contact lens exam to evaluate your eyes and vision with contacts.

Are Eyeglass Prescriptions the Same as Contact Lens Prescriptions?

No. An eyeglass prescription is for lenses positioned approximately 12 millimeters from your eyes, whereas a contact lens prescription is measured for lenses that sit directly on the surface of your eye. The contact lens prescription also includes the brand, lens diameter, and curvature, which are not part of an eyeglass prescription.

Contact Lens Fitting: One Size Does Not Fit All

If a contact lens is too flat or too steep for your corneal shape, you may experience discomfort or even eye damage. Your eye doctor will take certain measurements to determine the best contact lens design and fit for your eyes.

• Corneal curvature: Measures the curvature of your cornea so the eye doctor can select the optimal curve and diameter for your lenses.
• Pupil and iris size: The size of your pupil and iris is also important in determining the best contact lens design.
• Tear film evaluation: Evaluates the quality of your tears to determine whether they will adequately hydrate the lenses throughout the day. If you have dry eye disease, standard contact lenses may not be right for you.

Trial Lenses

Following the exam, you will be provided with trial lenses to verify that the chosen contact lenses offer clear and comfortable vision. This allows the eye doctor to make any fine adjustments to the prescription.
