Notes: *Prescribing guidelines from the American Academy of Ophthalmology for refractive error correction;

¹ Reduce the amount of refractive error by up to +2.00 D, and if this is ≥+7.00 D, reduce up to +3.00 D;

² Give the full cycloplegic refraction. If ≥+3.00 D, reduce it by +0.50 D;

³ When astigmatism is oblique, it must be corrected if >1.00 D;

** Minimum amount of refractive error that should be first treated with spectacles in recent trials by the Pediatric Eye Disease Investigator Group (2002).
