Eligibility

Age
18 Years to 40 Years

Inclusion criteria

Inclusion criteria: Healthy volunteers. Aged between 18 and 40 years. With no history of ocular diseases or current evidence of serious ocular conditions

Exclusion criteria

Exclusion criteria: Participants with refractive error greater than 6 diopters (myopia or hypermetropia), astigmatism greater than 3.00 diopters, antimetropic anisometropia. Diabetes. Pregnancy. Lactation. History of previous ophthalmic surgery

Design outcomes

Primary

MeasureTime 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

MeasureTime 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
