The Importance of Eye Exams for Contact Lenses

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? 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 an eye exam for contact lenses 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. A prescription for glasses cannot be used for contact lenses. 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 prescription for contact lenses also includes the brand, lens diameter, and curvature.

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. During your exam, your eye doctor will measure:

• Corneal curvature — to select the optimal curve and diameter for your lenses.
• Pupil and iris size — important in determining the best contact lens design.
• Tear film evaluation — to determine whether your tears can keep contact lenses and your cornea sufficiently hydrated throughout the day.

Trial Lenses

Following the eye 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.

Wearing the correct contact lenses allows you to enjoy all the benefits of contacts while keeping your eyes healthy and comfortable. Contact St. Clairsville Eyecare in St. Clairsville to book your contact lens eye exam today. Call (740) 695-0444.
