Background:

Preschool vision screening programs are widely implemented.
Evidence regarding the effectiveness of these programs is often limited.
Ethical considerations surrounding mandatory health interventions for young children are significant.

Purpose of the Study:

To evaluate the evidence base for preschool vision screening.
To discuss the ethical implications of vision screening for three- and four-year-old children.
To inform discussions on the continuation or withdrawal of such programs.

Main Methods:

Systematic review of existing literature on preschool vision screening effectiveness.
Analysis of ethical arguments concerning non-beneficial or minimally beneficial interventions for children.
Discussion of findings in the context of public health policy.

Main Results:

A systematic review found a lack of robust evidence supporting the effectiveness of preschool vision screening.
Concerns were raised about the ethical justification for screening young children when benefits are not clearly established.
The review suggests that the lack of evidence supports program withdrawal.

Conclusions:

The effectiveness of preschool vision screening is not adequately supported by current evidence.
Ethical considerations necessitate a re-evaluation of mandatory screening programs for young children.
Withdrawal of preschool vision screening programs may be warranted due to insufficient evidence of benefit.
