If you are interested in contact lens, we may perform a contact lens evaluation after your comprehensive eye exam. During the contact lens evaluation we perform the following tests to ensure that the contact lenses fit your cornea (the part of your eyes where the contact lens sits on) properly. Just as one shoe size doesn’t fit all, one contact lens size doesn’t fit all.
Different contact lens has different curvature. We use a keratometer to measure the curvature of the cornea to match it with an appropriate contact lens. Diameter of the cornea is also measured to ensure that the contact lens covers the cornea adequately. Our eye doctor would then use a microscope to ensure that the contact lens is in fact fitting the cornea properly. We look at the movement, centration and coverage of the contact lens.
Contact lens training is also required if you are new to contact lens. We will teach how to take care of your contact lenses and how to insert, remove your contact lenses properly without scratching or damaging your eyes.
*These special tests are not typically performed in routine eye exams for eyeglasses. Please let us know when you are booking for your eye exam, so we can schedule enough time in your appointment.
