You should consider the following factors when prescribing spectacles for a young child (under seven years of age)⁸¹:

1. Is the refractive error within the normal range for the child’s age?
2. Will this child’s refractive error emmetropise? 
3. Will this level of refractive error disrupt normal visual development or functional vision?
4. Will prescribing spectacles improve vision function or functional vision? 
5. Will prescribing spectacles interfere with the normal process of emmetropisation?
