Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The accuracy of the online refraction test results is expected to be comparable to both the subjective dynamic refraction performed by ophthalmologists and the refraction performed by the self-refractor | — |
Secondary
| Measure | Time frame |
|---|---|
| It is expected that the average duration of the online exam will be comparable to the subjective refraction time;The dial clock test is expected to be accurate in identifying the presence of astigmatism;It is expected that the comparison of the spherical and cylindrical degree obtained through the online refraction test with those obtained through the auto refractor technique and subjective dynamic refraction will show consistency and precision between the methods | — |
