A contact lens exam requires extra evaluation and time for both the doctor and patient. The spectacle prescription is first gathered and then the proper conversion to a contact lens prescription is determined. The two prescriptions may not necessarily be the same. A further measurement of the shape of the eye is taken to ensure that the contact lenses provide clear vision as well as fit properly. Once the contact is placed on the eye, it needs to be evaluated for its visual function and for its fit. The lens should be comfortable for the patient and should be acceptable in terms of centering on the eye and movement from the doctor’s perspective. New contact lens patients should budget extra time as they must learn to insert, remove and properly care for a contact lens before they are allowed to leave home with the contact lenses.
