|
Try to relax and remain still. Avoid talking during the test. You will sit in a reclining chair or lie down on an exam table in a softly lighted room. The technologist will measure certain points on your head. He or she will use a special pencil to mark the spots where electrodes will be placed on your scalp. Your scalp will be rubbed with a mild abrasive, and electrodes will be attached.

Detailed information on eye examinations and at what age they are recommended During an eye exam, an eye doctor reviews your medical history and completes a series of tests to determine the health of your eyes. The information from an eye exam may lead to medical procedures or prescriptions. Eye examinations should take place periodically as follows:

Detailed information on eye examinations in children Children are different than adults in that a child's brain develops more rapidly. Any problems a child may experience with his/her vision may disrupt the development of visual pathways to the brain. A critical stage of visual development occurs between birth and age 3 to 4 months, during which time the brain must receive clear visual messages from both eyes. Early detection and treatment can prevent loss of vision, learning difficulties, and delayed development.
