This category contains data on measurements related to the assessment of the participant's eye prescription (refractive error). This category includes data on whether the measurement was made, and the test result for refractometry (Sphere, Cylinder, Axis, Pupil diameter) and keratometry (corneal refraction and astigmatism) for each eye. This measure was added to the re-imaging visit towards the end of 2022.
