Often I get this question from parents whose children have passed a screening at the pediatrician's office. I understand why parents feel this way. Most people think that "seeing" means being able to read the distance eye chart. However, that is only a small part of how children (and adults) use their eyes in today's world. Think of how much we all need to see up close to read, work on the computer, and use handheld devices/games. Although the pediatrician screening is important, there is no substitute for a comprehensive eye exam to access all aspects of the visual system and the health of the eyes.
