A complete eye examination is performed to diagnose the overall health of your eyes and check any specific problems you are experiencing.
Your exam will include: a check of visual acuity, refraction for new glasses, examination of external eye structure, a glaucoma test, examination of the lid margins, conjunctiva, cornea, anterior chamber, lens and retina.
For a complete eye exam, your pupils will be dilated. Although it is not necessary in all cases, dilation is frequently needed to examine the inside of the eye for disease and problems. Dilation also makes measurements for glasses more accurate.
The dilation eye drops take 20 to 45 minutes to be effective, so plan to allow extra time in the office. Since dilation may cause your vision to be blurred for two to three hours, it is advisable to bring sunglasses and, if possible, someone to drive you home.
