It is important to identify vision problems in children as early as possible. These problems include amblyopia ("lazy eye," or reduced vision due to lack of development in the visual area of the brain), strabismus (eyes are not aligned correctly due to eye muscle problems), and refractive errors (when you need glasses to see up close or far away). Early identification of the vision problems allows them to be treated earlier which makes it more likely that vision can be improved. VisionQuest 20/20 can be easily distributed to schools, and it is easy for the child and the vision screener to use. The test can be performed by volunteers instead of an ophthalmologist.
