Table 3
Criteria for clinically significant refractive error
| Bilateral hypermetropia | ≥1.50Ds |
| Bilateral myopia | ≥1.50Ds |
| Bilateral astigmatism | ≥0.75Dc |
| All astigmatism in combination with hypermetropia | |
| Anisometropia | ≥1.00Ds |
| Full astigmatic, anisometropic myopic and mild/moderate hypermetropic (+2.00Ds to +5.00Ds) refractive errors will be prescribed. Prescriptions for high hypermetropes are given within 2.00Ds of the full correction. | |
