Brief summary
Software refraction in the mobilerone for myopia and astigmatism is a novel medical device for myopia adults and elder children with or without astigmatism. And the investigators would like to test its accuracy and efficacy as well as safety.
Detailed description
It's a software installed in a mobilerone with subjective guide on screen for testing myopic refractive error with or without astigmatism for adults or elder children. The investigators would like to compare its refraction results with retinoscopy.
Interventions
