Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Normalized logMAR Visual Acuity | Assessed at 2-hour post-baseline | Normalized logMAR visual acuity is the change in visual acuity (how well you can see) from baseline (spectacle). Normalized visual acuity is calculated by subtracting the logMAR visual acuity with a contact lens from the baseline (refraction without a contact lens). Each letter on the logMAR visual acuity chart has a value of 0.02. |

Outcome results
Normalized logMAR Visual Acuity
Normalized logMAR visual acuity is the change in visual acuity (how well you can see) from baseline (spectacle). Normalized visual acuity is calculated by subtracting the logMAR visual acuity with a contact lens from the baseline (refraction without a contact lens). Each letter on the logMAR visual acuity chart has a value of 0.02.
