Regular comprehensive eye exams are crucial for both adults and children to maintain eye health. An eye exam can help adults not only formulate and update their eyewear prescription, but also search for any sign of common eye diseases. For children, eye exams are even more important since vision is so closely related to their study. If they have poor vision or image interpretation, they are most likely to have a poor performance in their study. Parents should take children to a related professional doctor for an eye examination as soon as they get a reading or learning difficulty, in order to find out the potential vision root.

Different people should receive complete eye exams at different intervals. Children’s eyes should be examined at six months of age, three years of age, and six or seven years of age and every two years during school days, since high vision problem rates are reported among both preschool and school-aged children. For children with risk factors of vision problems such as prematurity, developmental delays, turned eyes, family history of eye diseases and history of eye injury, more frequent eye exams are necessary.

A comprehensive eye exam contains several tests, from simple eye chart reading to tiny structure visualization. Some factors play a role in deciding the exam time, such as caseload and test complexity.

Retinoscopy is always used to get an approximation of your prescription. You will be required to fixate on a large target and receive a light shined by the doctor. By changing lenses in front of your eyes and interpret the light reflects from your eyes, the doctor can work out the general prescription of your eyes.
