Summary
Recent Android mobile device technology is available which allows user-measured refractive error and reading add power. This technology could be quite useful to the clinical and research community. The current study aims to evaluate the accuracy, repeatability, and reproducibility of one such technology by VisionApp, specifically with regard to ghosting vision. VisionApp is an app which runs on a smartphone or other device which uses the distance between the user's face and the phone to determine refractive error, while the user looks at different targets (lines, letters, words, etc).

Interventions
Proclear 1 Day Contact Lens
Proclear 1 day is a commercially available single vision soft contact lens for single use (daily wear). Participants will wear these contacts at the beginning of the study visit to establish best corrected vision. Participants will then continue to wear this contact lens in one eye for the duration of the study visit.
MyDay Contact Lens
MyDay is a commercially available multifocal soft contact lens for daily wear. Adult participants will assess images for ghosting while wearing a MyDay contact lens in one eye. Order of exposure to this lens will be determined via randomization.
NaturalVue Contact Lens
NaturalVue is a commercially available multifocal soft contact lens for daily wear. Adult participants will assess images for ghosting while wearing a NaturalVue contact lens in one eye. Order of exposure to this lens will be determined via randomization.
MiSight 1 Day Contact Lens
MiSight 1 Day is a commercially available multifocal soft contact lens for daily wear. Children participants will assess images for ghosting while wearing a MiSight 1 Day contact lens in one eye. Order of exposure to this lens will be determined via randomization.
MiSight ABC Contact Lens
MiSight ABC is an investigational multifocal soft contact lens for daily wear. While the contact lens is made of an FDA approved material which is already marketed in the United States, it differs from commercially available lenses in that it has a slightly different optical design.Children participants will assess images for ghosting while wearing a MiSight ABC contact lens in one eye. Order of exposure to this lens will be determined via randomization.
VisionApp
VisionApp is an app which runs on a smartphone or other device which uses the distance between the user's face and the phone to determine refractive error, while the user looks at different targets (lines, letters, words, etc.)
