Problems solved by technology

The shortcoming of existing technology is that a parent, teacher, or caregiver may wish to quickly and affordably test a child's vision without the oversized paper eye charts of current technology or a clear, properly lit 20-foot space
[0012] Recently, there have been a plethora of free mobile apps (Apps) claiming to measure vision, but to replicate the 20’ Snell

Abstract

A system for replicating a standardized visual acuity test, such as the 20' Snellen test may comprise a binocular viewer attached to a smartphone. A binocular viewer may comprise a housing comprisinga pair tube covers having voids allowing for viewing through a pair of lens tubes with each lens tube in visual communication with a second lens, a first lens, an aperture and a front cover. The optical systems use an artful combination of front and back lens surfaces, demagnification and other systems to faithfully replicate the sight lines perceived by a user of a traditional 20' test. The system also allows for the incorporation of other tests conducted with both eyes including Color Sensitivity and Contrast, furthermore by placing a deformable, tunable lens between the second lens and theeye the device serves as an ophthalmic refractometer, allowing a Spherical Equivalent refraction estimate for each eye.
