Contact Lens Evaluation

Contact Lens Evaluation

If you are interested in contact lens, we would perform a contact lens evaluation after your comprehensive eye exam. During the contact lens evaluation we perform diagnostic 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.

Power of your contact lens requires adjustments, because contact lenses sit on the cornea while glasses sit on the nose. This is important for any astigmatic and moderate to high nearsighted prescription. In the case of multi-focal contact lenses, this is especially important, as there is a fine balance between your distance and near vision.

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. We consider the diameter of the cornea to ensure that your contact lenses cover the cornea adequately. Our eye doctors 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

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.
