Optometrists dilate a person's eyes so they can see the inside and back of the eyes. An eye exam should be performed annually. An ophthalmologist examines a patient. Normally, a person's pupils contract when light is bright. Routine eye exams are painless and can help detect vision or eye problems early.
Why should I have my eyes dilated? Dilation allows Drs. Goering or Hageman to have a better view inside your eye to make sure your eyes are healthy. It is much like opening a door to see inside a room instead of looking in through a small window. With dilation, one can see the optic nerve head, blood vessels, the macula and out to the periphery of the retina.
