A contact lens exam is a comprehensive eye examination that specifically focuses on determining the best type of contact lenses to suit a person's visual needs and to make sure that they can be safely and comfortably worn.
During a contact lens exam, an eye doctor will perform several tests to assess the health of your eyes, your visual acuity, and the shape and size of your corneas. These tests may include:
1. Visual Acuity Test: The eye doctor will measure your ability to see clearly at various distances, both with and without corrective lenses.
2. Refraction Test: This test will determine the prescription needed for your contact lenses.
3. Corneal Shape and Size Evaluation: This test measures the curvature and size of your corneas, which is important for determining the appropriate type of contact lenses for you.
4. Tear Film Analysis: Your eye doctor will check the quality and quantity of your tears, which is important for wearing contact lenses comfortably.
5. Slit Lamp Examination: A slit lamp is a microscope that the eye doctor uses to examine the front of the eye, including the cornea, iris, and lens.
Once these tests are completed, the eye doctor will use the results to recommend the best type of contact lenses for you, based on your visual needs, lifestyle, and the health of your eyes. The eye doctor will also provide instructions on how to properly insert, remove, and care for your contact lenses.
It's important to have a comprehensive contact lens exam to ensure that you have the correct prescription, the best type of contact lenses for your eyes, and the proper instructions for their use. This will help you to safely and comfortably wear your contact lenses.
