  • Telemedicine refraction (Device), also known as Glasses,, Contact lenses,, Refractive surgery,
  • Traditional refraction (Device)

+Outcome measures

Primary outcomes

  • refraction in diopters over telemedicine compared standard phoropter refraction [an average of 1 year]

Secondary outcomes

  • telemedicine refraction results beyond dioptric readings [an average of 1 year]: to see if there are other uses for telemedicine refraction results

Other outcomes

  • patient satisfaction from telerefraction [an average of 1 year]
