Plan to be at your doctor’s office for at least an hour for a comprehensive eye exam. There are many steps to the examination, and each of these takes time. You may have some downtime during part of your visit, as the doctor awaits the dilation drops to take into effect. If you are found to need supplementary testing, such as a visual field, for example, additional time may be required. Child exams may require longer appointments. Please discuss that with one of our patient care coordinators.
