Interventions

• Proclear 1 Day Contact Lens — DEVICE
  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 — DEVICE
  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 — DEVICE
  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 — DEVICE
  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.
• Investigational Contact Lens — DEVICE
  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 this investigational contact lens in one eye. Order of exposure to this lens will be determined via randomization.
• VisionApp — DEVICE
  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.)

Study Details

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).

Arms

• Active Comparator: Adults: Lens 1, then Lens 2
  Subjects will be asked to look at letters and describe any shadows or distortions they see using slider bars or numerical rating scales. This will be performed twice, while wearing two different soft multifocal contact lenses in one eye. The order in which the participant wears each of the multifocal contact lenses for these tasks will be randomized. After the assessment while wearing the first multifocal lens is completed, subjects will repeat the task while wearing the second multifocal lens.
