Primary Outcome Measures

Name	Time	Method
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 Outcome Measures

Name	Time	Method
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
