| **Refraction:** Visual acuity and refraction were measured for both eyes with an autorefraction device. The participant is seated with their forehead and chin placed on rests on the device. They are asked to focus on an image within the device while the auto-refraction occurs. Next, a letter chart is projected and the visual acuity is determined. The visual acuity threshold for abnormality is defined as <0.5. | **Refraction:** Visual acuity and refraction were measured for both eyes with an autorefraction device.
