An automated ophthalmic system is disclosed that is utilized to examine the eyes of a subject. A refraction system measures the refractive error of each eye and identifies a lens to correct the refractive error detected. A display presents one or more optotypes to the subject to ascertain the refractive error. An interface device receives a wireless signal from the refraction system, converts the wireless signal into one or more ASCII characters, and communicates the one or more ASCII characters to the display to present the one or more optotypes.
