About

Self evaluating tools based on smartphone devices are public available on the market for each person. The tools are used to estimate the existing refractive error for each eye of a patient. Hereafter, e.g. ordering glasses via internet could be the next step for this persons.

The daily routine within an eye hospital shows, that estimation of the refractive error is a difficult and time consuming procedure.

The study compares the results of the measured refractive error using a smartphone based tool with the results of conventional measurement methods.
