An eye exam usually involves these steps:
You’ll be asked about your medical history and any vision problems you might be experiencing.
Your eye doctor measures your visual acuity to see if you need glasses or contact lenses to improve your vision.
You’ll be given numbing drops in your eyes. Then your doctor measures your eye pressure.
Your eye doctor checks the health of your eyes, possibly using several lights to evaluate the front of the eye and inside of each eye. To make it easier for your doctor to examine the inside of your eye, he or she will likely dilate your eyes with eyedrops.
Your eye doctor discusses what he or she found during the exam and answers questions you have about your eyes.
Part of the examination, such as taking your medical history and the initial eye test, may be performed by a clinical assistant.
Several different tests may be performed during the eye exam. The tests are designed to check your vision and to examine the appearance and function of all parts of your eyes.
