Vision device validation
In the single arm of this study, all members of this group were examined using a number of mobile eyesight assessment devices.
Device: Vision device validation
Group members had their vision tested with the following devices/methods: Eyenetra NETRA, PlenOptika Quicksee, Right Manufacturing Retinomax K Plus 3, and standard eyesight tests using eye charts, phoropters, and slit lens lamp imaging.
- Accuracy of Assessment of Participants' Best Visual Acuity (in Diopters) [ Time Frame: 1-2 hours ]Measurements of participants' best visual acuity as measured by mobile devices compared to "gold standard" of subjective refraction
