It is very important that you have regular eye exams; it is the only way to monitor your visual health. To ensure that a thorough exam can be carried out, the eyes are dilated, this is not painful or complex, a few drops in the eye forces the pupil of the eye to remain wide open, it will not close up even under bright light. Although there is no pain at all associated with pupil dilation, you can write off a good part of your day; the drops take a good half hour to work and at least another four to six hours to wear off and let your pupil return to normal function. Why is pupil dilation even necessary?

During a normal eye exam, the Optometrist will shine a bright light into the eye, this allows him to see the cornea, lens and iris; Inspecting for any issues. If the pupil has not been dilated, the moment the bright light is shined into the eye, the pupil will close making it all but impossible for the Optometrist to study the details of the eye.
