This is a protocol for a Cochrane Review (Intervention). The objectives are as follows:

The primary objective of this review will be to evaluate the effects of vision screening in reducing the prevalence of amblyopia in comparable screened versus unscreened populations. Subgroup analyses are planned, if appropriate, to determine the effect of the type of personnel conducting the testing, the age at screening, and the threshold applied for failure. Secondary objectives will be to report available evidence regarding the disability associated with living with uncorrected amblyopia and to document reports of the potential harms and costs associated with screening.
