Primary Outcome Measures

Name	Time	Method
refraction in diopters over telemedicine compared standard phoropter refraction	an average of 1 year

Secondary Outcome Measures

Name	Time	Method
telemedicine refraction results beyond dioptric readings	an average of 1 year	to see if there are other uses for telemedicine refraction results
